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 type and parameters of coal-fired boilers are the direct factors affecting the cost of a small coal-fired boiler. For example, rated capacity, rated steam pressure, rated steam temperature, feed water temperature, etc. With different parameters, the more requirements, the higher the price.
The ignition of industrial coal-fired boiler needs to be operated steps by steps, and the ignition operation is different according to the specific model of industrial coal-fired boiler. Grates of industrial coal-fired boilers are usually divided into manual grates and mechanical grates. Here, according to the different grates, the correct ignition steps of industrial coal-fired boilers are introduced in detail.
The efficiency of a coal-fired boiler depends on the loss of the boiler, the best efficiency in the boiler can be achieved if the losses are kept to the minimum. Since 50% of the losses are dependent on the fuel and ambient condition, the best efficiency can be achieved by properly tuning the other 50%, i.e. mainly carbon loss and dry gas loss.
The special spray gun for pulverized coal boilers is a kind of equipment that atomizes fuel oil (light oil, heavy oil, residual oil, etc.) to make the fuel oil into UM-level particles. Through air distribution and ignition, the fuel oil can be sufficiently burned. It is widely used in the boiler industry.
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.
