The coal is usually smashed to be the pulverized coal for boiler combustion. This is an introduction to the causes and treatment methods for the extinguishment of the pulverized coal fired boiler.
In the boiler operation,the flue gas discharged from the flue gas duct has a certain temperature. However, the abnormal increase of flue gas temperature in boiler's flue gas duct is usually accompanied with other abnormal phenomena. In this regard, corresponding measures should be taken for adjustment based on the reason analysis.
1) Set up the air preheater. One of the most effective measures to improve the thermal efficiency of thermal oil heater is to use an air preheater for heat recovery. 2) Use waste heat boiler for heat recovery. The waste heat boiler uses the waste heat in the flue gas exhausted from the thermal oil heater to heat water or generate steam.
Once the flameout of gas-fired or oil-fired boiler is confirmed, the boiler should be shut down for inspection and maintenance in time according to the operating regulations. Only after the inspection and test are completed, the boiler can continue to be used.
Before the operation of oil-fired boiler, we should effectively adjust the heating system to make it conform to the actual working conditions. Moreover, what are the specific operating steps when adjusting the oil-fired boiler?
