As the state environmental protection requirements become more and more strict, there are also relevant regulations and standards for boiler pollutant discharge. As a result, what is the sequential process of desulfurization and denitrification for the coal-fired boiler?
Whether the water quality in the gas-fired boiler reaches the required standards is directly related to the safety, performance and service life of boiler. The water must be treated before the boiler operation. However, what are the water quality standards for the gas-fired boiler?
With the continuous development of boiler manufacturing process and technology, fuel types of boiler have also increased, such as various combustible gases, fuel oil, biomass, coal and so on.
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.
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.
Coal is one of the main fuels used by boilers, especially the coal-fired boiler. In order to reduce the production costs, we need to know whether the coal-fired boiler saves coal in operation.
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?
