During the ignition and operation of the chamber combustion boiler fueled by pulverized coal, oil or combustible gas, improper operation can cause the deflagration or secondary combustion in the furnace or flue gas duct, which can further cause the increased pressure in the furnace. When the pressure reaches a certain value, the explosion-proof door is necessary to open automatically to protect the furnace wall of the boiler.
Boiler is a kind of thermal energy conversion equipment composed of drum and furnace. It uses fuel combustion to heat water into steam or hot water to provide power for production or help auxiliary production. With the continuous improvement of industrial manufacturing technology, boiler's control has also changed from the traditional full manual operation to the present automatic intelligent control.
A well designed and operated biomass boiler burning fuel within the specification of the boiler should not produce any smoke, but black smoke may be produced if the fuel is too wet for the boiler. All biomass boilers produce some oxides of nitrogen (NOx), particularly nitrogen dioxide (NO2). While NOx emissions from gas boilers have been reduced significantly in recent years through the use of low NOx burners which burn at a temperature slightly below that at which NOx forms, the nature of biomass combustion, and the need to ensure the complete combustion of wood gases, means that combustion takes place at a temperature where atmospheric oxygen and nitrogen can chemically combine. The better the quality of the combustion control system on a biomass boiler, the lower the NOx emissions will be. In general, biomass boilers produce less NOx than oil boilers. Biomass boilers do not produce any oxides of sulphur (SOx).
In the whole drying process, we should pay attention to gradually increasing the temperature instead of burning by raging fire; regularly checking boiler's water level and keeping it within the normal range; keeping the flame balanced in the furnace. In addition, we also should properly open the drainage valve and maintain the water level, regularly record the flue gas temperature to control the rise of temperature and high temperature and keep the temperature within the normal range. In general, under these conditions, boiler’s drying quality can be ensured.
The pollution discharge of the biomass-fired boiler is less than the coal-fired boiler. It is also necessary to deal with the exhaust gas of the biomass-fired boiler to meet the national standards before boiler ignition and operation.
The coal-fired boiler has always been one of the important boiler types in the industrial production and its operating costs and capacity play an important role in the enterprise operation.
The thermal efficiency of an industrial boiler is a measure of how effectively the boiler converts the energy contained in the fuel into usable heat. It is typically expressed as a percentage, indicating the ratio of heat output for heating or producing steam to the energy input from the fuel consumed. This efficiency is crucial for understanding the performance of a boiler, as it directly impacts fuel consumption, operational costs, and environmental emissions.
