Alkane gas is the main gas, liquefied gas and other gases can also be used as fuel for direct fire heating of non-fixed household kitchenware, hotel supplies, and outdoor leisure supplies. Cassette stoves are also called portable butane gas stoves; portable barbecue grills are a type of kitchenware that has just emerged in recent years and are mostly used for home outdoor leisure and hotel supplies. According to the appearance, it is mainly divided into single-eye, double-eye, mini and ultra-thin types, and single-purpose and dual-purpose cassette furnaces. Historical development (1) Initial stage (2002-2003) The product structure is simple and the function is single. Before the 20th century, there was almost no development of China's cassette stove industry. The popularity of domestic concepts such as outdoor leisure was very low, and there was almost no People would think of a kitchen utensil that is easy to carry outdoors or is not fixed and easy to transport. It was not until 2002 and 2003 that one or two domestic companies began to research and develop cartridge furnaces. Moreover, the product structure is simple and the function is single. In addition, the awareness of outdoor leisure in China has not yet risen, so the development is average. (2) Development stage (2003-2009) Durability and reliability are greatly improved. After 2003, as the national awareness of leisure continued to increase, the cassette stove market economy emerged. Various foreign cassette stove appliances entered China one after another, and the development of the domestic cassette stove industry also began to enter the development stage. The product quality and appearance of the cassette furnace have been fundamentally changed, and the product varieties and functions are also constantly changing. During this time, panels, combustion systems, and ignition were also improved. The panel material is cold plate spray plastic, the burner has aluminum burner head, copper burner head, the surface is electroplated or zinc sprayed, the regulator has plug valve and screw valve, the ignition device uses piezoelectric ceramic electronic ignition, which improves the ignition rate , the durability and reliability of gas stoves have been improved. (3) Breakthrough stage (2009-2012) The variety increases and the styles are complete. After 2009, China's cassette furnace industry entered a stage of rapid development. The introduction of foreign advanced cassette furnace development and manufacturing technology has brought about breakthrough changes in China's cassette furnace industry. The varieties have increased, the measures have been strengthened, the materials and styles are novel, and safety, function and performance have all been improved. There have also been improvements in production quality and reliability, process level, degree of automation and intelligence, advancement of performance indicators, energy conservation and environmental protection, and safe use. The regulator for the cassette stove basically eliminates the screw valve. The safety of the plug valve cassette furnace, the exquisite and exquisite appearance treatment, the heat-resistant furnace shell and pot holder, the piezoelectric ceramic ignition for tens of thousands of times, and the perfect printing process are the mainstream consumption of the cassette furnace market in recent years. The cassette furnace industry is developing rapidly. It already has several Chinese brands of cassette furnaces recognized by the state, as well as several foreign companies and several domestic companies with foreign investment. Cassette stove classification Classification overview There are many classifications of cassette stoves, basically single-eye, double-eye; single-purpose, dual-purpose; ordinary type, ultra-thin type, and mini type. From the classification, we can see that this type of classification is mainly distinguished by the number of combustion eyes of the cassette stove. Some on the market only have single eyes and double eyes. The basic structures of single eyes and double eyes are actually the same. The difference lies in the difference in volume and the number of combustion eyes. The difference between single-use and dual-use is the difference in the air inlet device on the regulator. The single-use cassette stove is only suitable for installing butane gas cylinders. The dual-purpose cassette stove is suitable for domestic liquefied gas combustion in addition to its single-use function.

Ordinary type, ultra-thin type, and mini type are classifications of appearance volume. From the literal meaning, the ultra-thin type means the overall height of the shell is lower, the mini type means the smaller volume, and the ordinary type refers to the commonly used ones on the market. of cassette stove. Working Principle When the cassette stove is working, the butane gas enters the regulator from the butane cylinder, and after being adjusted by the regulator (the user adjusts it through the knob), it enters the burner head, and at the same time mixes a part of the air (this part of the air is called (for primary air), these mixed gases are ejected from the flame holes of the flame distributor and are ignited by the ignition device to form a flame (the air required for combustion is called secondary air). These flames are used to heat the pot holder. cooking utensils. Ignition methods There are two popular ignition methods for gas stoves: electronic pulse ignition and piezoelectric ceramic ignition. Cassette stoves mostly use piezoelectric ceramics for ignition. The biggest advantage is that they do not require batteries. However, the success rate of ignition is related to the ambient humidity. It is difficult to ignite when the humidity is high. In addition, you need to press and hold the switch to start the ignition, which is not as fast as electronic pulse ignition. Of course, the success rate and number of ignitions of piezoelectric ceramics also depend on the quality of the magnetic needle. A good magnetic needle can ignite tens of thousands or more times, while an ordinary or poor quality magnetic needle may only ignite a few thousand times. Safety device For the safety of the cassette furnace, it is very necessary to have a safety device in the cassette furnace. Most of the cassette furnaces on the market now use a regulating valve to sense the pressure in the valve body and gas cylinder. The increase and decrease in pressure causes the explosion-proof rod in the regulating valve to perform corresponding actions. For example, when the pressure is too high, if If there is no regulating explosion-proof device of the regulating valve, it may cause the gas cylinder and the regulating valve to explode due to excessive pressure. When there is a safety device, if the pressure is too high, the explosion-proof rod in the regulating valve will perform corresponding actions. Isolate the entry of gas by touching the cylinder lever or cutting off the gas inlet and outlet to stop the hidden dangers caused by the continued increase in pressure. Purchase matters 1. Selection of purchase location. When purchasing a cassette stove, you should go to professional large stores, shopping malls and offices of various sales companies in various places. Never buy at street stalls or small shops for convenience or cheap prices, let alone Buy "three no's" products. After purchasing, don’t forget to ask for a formal invoice, and keep the warranty certificate and invoice. Otherwise, users will be helpless if quality problems arise. 2. Look at the packaging and appearance. The packaging of the cassette stove reflects the quality of the product to a certain extent. Qualified cassette furnaces should be neatly packaged, beautifully printed and fully marked. After opening the package, the appearance of the cassette furnace should be beautiful and elegant, with no collisions anywhere in the body, and the paint surface of the product should be even and smooth, with no blistering or peeling off. The overall structure of the cassette stove should be stable and reliable, the stove surface should be smooth and flat without obvious warping, and the installation of parts should be firm and reliable without looseness. The parts are finely processed, the connecting parts are firm and reliable, and the pot supports should be stable and firm. The parts of inferior cassette stoves are roughly processed, and some even have obvious pores and blisters on the gas line system, which not only affects the normal use of the stove but also It can easily cause personal injury accidents. Due to shoddy manufacturing, cutting corners, and primitive assembly techniques of inferior cassette stove manufacturers, the parts of the stove are loose, the parts do not match each other, the valves or knobs are inflexible, the stove body is not strong enough, the stove surface is seriously deformed after bearing load, and the stove body is warped. Qu et al. 3. On-site ignition test When purchasing a cassette furnace, you must not only look at the appearance and other processing quality, but also need to conduct an ignition test. If the store does not have the conditions for a fire test, you should test the fire in time after buying it home. If it does not work, you should return it in time. When testing the fire, the electric ignition device should be flexible and reliable. It should ignite 10 times in a row and ignite at least 8 times. The flame should spread throughout the entire fire eye within 4 seconds without deflagration. A blue flame appears, the inner and outer cones of the flame are distinct, there is no backfire, no dead fire, and basically no yellow fire. The noise of igniting and extinguishing the flame should be small. Otherwise, the gas will not burn fully and the carbon monoxide will exceed the standard, which will endanger human health. 4. Weigh the stove. Weigh the stove with your hands. Products that meet the standards have sufficient weight due to the use of high-quality materials. Inferior stoves are lighter in weight due to their thin material. Troubleshooting: After a period of use, the cassette stove has smaller flames due to external factors such as weather, dust, etc., and sometimes it even fails to ignite. Consumers who encounter these problems must not blindly disassemble the machine to check. Experts have focused on these common problems. The question gives us a detailed answer. If you encounter problems with the use of cassette stoves, you may wish to pay attention to: What measures should be taken when using cassette stoves for hours? The normal flame of a cassette stove is light blue, the flame inside the flame is clear, the height is about 60mm, there is slight noise, and the firepower is strong.

If the flame is very small, the reasons and troubleshooting methods are as follows: 1) The fire hole of the burner fire cover is blocked by dirt, which hinders the flow of mixed gas from the burner. Clean the fire hole dirt. 2) If the nozzle is clogged, unscrew the nozzle and clean it. 3). The air inlet and nozzle of the pressure regulator are blocked by rust, which hinders the flow of gas from the bottle. Replace the pressure regulator with a qualified one. 4) If the copper pipe is flattened and ventilation is blocked, straighten the copper pipe or replace it. 5) In addition, you should also pay attention to reasons such as the gas is about to be used up and the valves are not fully opened, and corresponding measures can be taken to solve the problem. Is it normal for the cassette stove to be red-hot? Why are cassette stoves booming? The red fire of the cassette stove is mainly caused by the following reasons: 1) Gas reason: When there is too much moisture or impurities in the combustion gas, the flame color will appear red. 2) Causes of dust: When there is dust in the house or when the amount of moisture and oil and gas in the air increases when cooking, red fires are also likely to occur. 3) Cause of damper: This situation may also occur when the damper is not adjusted well. 4) Reasons for the pot holder: Because the enamel on the surface of the pot holder turns red when heated to high temperatures, and due to the special material of the enamel, the flame around the pot holder will be red, which is the color of metal ions at high temperatures. Therefore, red fire when burning is not a problem with the stove, but is caused by the above reasons. It will not affect normal use and will not be harmful to human health. What should you do when your cassette stove keeps failing to ignite? If the gas stove fails to ignite, you should check according to the following procedure: First, check whether the gas source switch is on. If it is on, then secondly, check whether the connecting copper pipe is If it is not flattened or bent, then, finally, pick up the pot support and see if there is fire at the ignition nozzle: 1) If there is no fire, check whether the discharge needle discharges a. If the discharge needle If there is no discharge, it means that the discharge needle is faulty and should be replaced. b. If the discharge needle discharges, it means that part of the air path is blocked or the valve body is faulty, and the valve body should be replaced. 2) If there is a fire: a. If it can burn normally, it means that the ignition position is too high. The user should be instructed to gently press the igniter down a few times and then put the pot support on it. b. If there is a fire, but the flame is too weak and cannot reach the burner head, the gas pressure is too low. It may be that the gas cylinder is almost used up or the regulating valve is maladjusted. c. If there is a fire, and the flame can reach the fire cap, But if it doesn't catch fire, it means the valve body is clogged. Instruct the user to use a thin wire to clear the nozzle.
