  • What are the energy-saving measures of industrial coal-fired boilers? 2020-10-23
    Coal-fired boilers are applied in various industries for the industrial and civil uses to generate steam and hot water. The steam is mainly used for production and the hot water is mainly used for heating and daily use.
  • What are the causes and treatment methods for the slugging of the circulating fluidized bed boiler? 2020-10-09
    The slugging for the circulating fluidized bed boiler means that the bubbles in the feed layer converge and grow. When the diameter of the bubbles grows close to the cross section of the bed, the feed layer is divided into several sections to be particle layers with intervals of bubble sections. The particle layers are pushed by bubbles to move upwards to a certain height and then they burst into a large number of small particles that are thrown out of the bed and carried away by bubbles, while the large particles fall down like rain.
  • What are the causes and treatment methods for the extinguishment of the pulverized coal fired boiler? 2020-10-09
    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.
  • What is the meaning of slugging for the circulating fluidized bed boiler? 2020-10-02

  • What is the sequential process of desulfurization and denitrification for the coal-fired boiler? 2020-09-18
    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?
  • What are the reasons for and solutions to the increase in flue gas temperature of coal-fired boiler? 2020-09-11
    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.
  • What is the heat loss in the operation of coal-fired boiler? 2020-09-04
    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.
  • How to directly tell whether the coal-fired boiler saves coal? 2020-08-21
    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.
