Chain grate has certain selectivity for coal types, and soft coal with volatile content above 15%, ash melting point above 1250℃, moderate particle size and calorific value above 18800~21000kJ/kg is more suitable.
The chain grate is the combustion equipment of coal-fired steam boiler. There are three main types and structures: chain belt grate, scale grate and beam grate.
The thermal oil heater, also called the organic heat carrier boiler, is a kind of once-through boiler developed based on the forced circulation design concept. With gas, oil or coal as the fuel and heat conducting oil as the medium, the thermal oil heater adopts the thermal oil pump to force the medium conducting the circulation in the liquid phase. The medium transfers the heat energy to the heating equipment and then returns to the furnace for being reheated. The thermal oil heater has the advantages of high-temperature and low-pressure heating and precise control of the medium.
The coal-fired boiler has low fuel costs and high calorific value, which is a kind of important auxiliary heating equipment in the production-oriented enterprises. However, the coking on the furnace wall is common in the operation of the coal-fired boiler.
The fuel is necessary for the boiler operation. The fuel choice can also affect the overall boiler operating efficiency and the pollution emission of the boiler. What are the differences between the oil-fired boiler and coal-fired boiler?
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.
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.
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?
