The food processing needs the steam or hot water to assist the production and improve the efficiency. Usually, the food plant needs the small tonnage boiler, so the coal-fired boiler is not recommended.
The biomass-fired boiler is a kind of equipment that uses the combustion of renewable energy biomass to provide heat energy for the boiler. The biomass-fired boilers are widely used especially by the enterprises located in the areas with abundant biomass fuel.
What are the reasons for the low efficiency of dust collector of the biomass-fired boiler? They are nature of dust, quality of bag and velocity of filtering.
The exhaust gas heat loss of coal-fired boiler is caused by the flue gas removed by final stage heat exchanger. The flue gas will take away a part of heat, mainly including the heat taken away by dry flue gas and the sensible heat with water vapor in the flue gas. What’s more, if the combustible gas in the coal-fired boiler is not completely burned, there will be heat loss as well. Therefore, this kind of heat loss mainly depends on the content of incomplete combustion products in the exhaust smoke.
If the boiler gives overpressure indicator which affects boiler's safe operation, depressurization measures should be taken. However, please pay attention that depressurization can not be too fast. After the overpressure problem of steam boiler is solved, we should check the internal and external parts of boiler to ensure that everything is going well.
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?
There are many skill indicators involved in the operation of oil-fired boiler, some of which are variables. We must master the relationship between variables and working effect of oil-fired boiler to realize better regulation.
The fuel of coal-fired boiler will release some harmful substances after combustion that are harmful to human body, but also pollute the environment. Therefore, the desulfurization treatment is required for coal-fired boiler, including desulfurization before combustion, desulfurization during combustion and desulfurization after combustion. The specific operating methods are different.
