What are the causes, symptoms, and treatment methods for the inclination of the fire layer in a pulverized coal pressurized gasification furnace?
Gouging and wind tunnels appear in the bed layer; the coal layers within it stick together, and the particle size of the coal changes. The jacket leaks water, the distribution of the gasifying agent is uneven, the oxygen content in the raw gas at the outlet may be higher, the outlet temperature is higher, as well as the temperature of the ash lock. It is necessary to check constantly for any unburned coal in the ash, and to monitor the oxygen content in the gas at the outlet. Reverse the grate arrangement and adjust the coal sample; if the ash is wet, then examine the water consumption of the boiler.
