Why is the pressure of the burner cooling water lower than that of the gasification furnace? Keeping the pressure of the burner cooling water lower than that of the gasifier is intended to prevent cooling water from flowing into the gasifier in case of a leak in the burner coils; this would otherwise damage the furnace walls and bricks, cause a sudden drop in furnace temperature, and harm the high-temperature components inside the gasifier, leading to unpredictable and negative consequences. The burner cooling water pipeline is equipped with a CO alarm; it is also possible to determine whether there is a leak of process gas by monitoring changes in the cooling water outlet temperature and water flow rate. Of course, it is also necessary to take into account factors such as the pressure and load of the gasification furnace; these can vary under different conditions. It is necessary to determine the appropriate action based on the extent of the leakage.
