Chain boiler is a kind of mechanized combustion boiler equipment which is widely used in industrial boilers. It is named for its grate similar to chain crawler. There are many types of boiler parameters, but they must be understood by users when selecting the boiler. ZOZEN Boiler introduces the parameters of 20-ton chain grate boiler.
The 20-ton chain grate boiler drives the chain grate to rotate through the reducer, which makes the solid fuel catch fire from the front and burn out at the tail ...
Advantages:Chain grate is a kind of better combustion equipment in layer combustion furnace. Compared with gas-fired boilers on the market, the solid fuel used in chain grate boiler does not need pipeline laying, and the cost is relatively low. Moreover, the chain grate boiler system is simple, and the manufacturing cost and operating cost are relatively low.
Disadvantages:The chain grate boiler has a limit on the coal types. The combustion mode of the chain grate is moving hearth combusti...
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 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.
