Coal Fired Chain Grate Boilers from ZOZEN Boiler

1. What is a coal-fired chain grate boiler?
A coal-fired chain grate boiler is a type of industrial boiler that uses a chain grate as its combustion equipment. The fuel enters the chain grate through the coal hopper and moves along the grate to undergo combustion. The burnt coal cinder is then discharged at the end of the grate. This type of boiler is widely used in industries such as food, paper, construction, cable, electronics, tobacco, and textile for processes like drying, disinfection, sterilization, and distillation.
2. What are the main types of chain grates used in coal-fired steam boilers?
There are three main types of chain grates used in coal-fired steam boilers: chain belt grate, scale grate, and beam grate. Each type has its own structural characteristics and is suitable for different combustion requirements.
3. What are the advantages of ZOZEN's coal-fired chain grate boilers?
