What is the reason for slow gas supply to the boiler
① In the operation of a steam boiler, if there is a decrease in load, the steam pressure continues to rise. If the water level is at a high level at that time, the combustion intensity should be reduced first. Further reduce the water supply to stabilize the water level of the steam boiler and keep the steam pressure within the design range of the boiler. If the water level is at a low level at that time, the boiler water supply should be increased, and the combustion intensity should be adjusted according to the change in steam pressure after the water level returns to the normal position.
② If the load increases during the operation of a steam boiler, the steam pressure will decrease. If the water level is too high at that time, the water volume should be reduced first, or the water supply operation should be suspended directly, and the coal and air supply should be increased. On the basis of strengthening combustion, it is necessary to gradually increase the feedwater for the steam boiler to ensure normal steam pressure and water level.
