What are the safety hazards of coal-fired gasifiers? Will the heating pipes explode over time?

Precautions for using coal-fired gasification heating furnaces. 1. It is strictly forbidden to let the stove burn dry without water to prevent accidents and burn out of the stove. The expansion water tank ensures normal water level. 2. The expansion water tank must not be sealed. It is strictly prohibited to install a valve between the water tank and the furnace outlet connecting pipe. If the water pavilion is installed on the return pipe, an exhaust elbow must be installed on the top of the main production pipe above the furnace. In addition, the water tank must not be installed outdoors to prevent accidents caused by the inability to vent after freezing. 3. Frequently check the pressure relief pipe to ensure that it is open, and operation under pressure is strictly prohibited. 4. If the water temperature of the furnace rises sharply and out of control, causing water overflow, the fire should be stopped to check the cause and handle it appropriately. 5. During a ceasefire in winter, the system water should be drained to avoid freezing and cracking. 6. Do not use flammable materials in the chimney. If the part of the chimney that comes out of the room and contacts the roof is a flammable structure, it should be fireproofed to prevent fire. 7. The stove is strictly prohibited to be installed in the bedroom or a room directly connected to the bedroom to prevent gas poisoning
