Difference between hot water boiler and steam boiler
1. Different composition structures
The structure of hot water boiler is relatively simple, mainly composed of burner, boiler body and heat exchanger. However, the structure of steam boiler is more complicated, which includes not only burner, boiler body and heat exchanger, but also steam generator, condenser, safety valve, pressure gauge and other components to ensure its safe operation under high pressure and high temperature.
2. Different working principles
A hot water boiler is a device that burns fuel and heats water to a certain temperature to provide hot water. Its working principle is relatively simple, and it only needs to transfer the heat generated by fuel combustion to water to heat it. The steam boiler generates steam by heating water to boiling state to provide power or heating. Steam boiler needs higher temperature and pressure, so its structure and working principle are relatively complicated.
3. Different application fields
Hot water boilers are mainly used for heating and hot water supply. They can transfer heat to buildings and families through hot water supply systems, and are widely used in homes, hotels, hospitals and other places. Steam boilers are mainly used to provide steam, which can transfer heat to various equipment and machines through steam pipes, and are widely used in industrial production, food processing, chemical industry, power generation, transportation and other fields.
4. There are differences in thermal efficiency
The thermal efficiency of hot water boilers is relatively low, usually around 8%. The thermal efficiency of steam boiler is higher, which can reach more than 9%. This is because the heat transfer efficiency of steam boiler is higher and the fuel is burned more fully.
5. Different environmental protection performance
There are also differences in environmental protection between hot water boilers and steam boilers. The flue gas of hot water boiler contains a lot of carbon dioxide and water vapor, which has a great impact on the environment. The flue gas of steam boiler contains less carbon dioxide and water vapor, which has little impact on the environment. Therefore, steam boilers are more popular in areas or places with high environmental protection requirements.
6. Is the maintenance different?
both hot water boilers and steam boilers need regular maintenance to ensure their normal operation and service life. The maintenance of hot water boiler is relatively simple, generally only need to clean and replace accessories regularly. However, steam boilers need more complicated maintenance procedures, including regularly checking whether the parameters such as pressure and temperature are normal, and replacing badly worn parts in time. Therefore, the maintenance cost of steam boilers is relatively high.
