  Boiler GrateIt is a type of mechanized combustion equipment that is widely used in industrial boilers. This time, the manufacturer of the boiler grate will systematically explain its function.

  Function:

  The boiler grate is a type of mechanized combustion equipment that is widely applied. The function of the boiler grate is to allow solid fuel to burn evenly.


Boiler Grate


  Boiler GrateCompared to recovery furnaces, vibrating furnaces, and bubbling furnaces, the boiler grate has higher quality requirements for coal types. Mechanical coal throwing furnaces basically belong to the infinitely ignited layer combustion grates, which have a relatively wide adaptability to coal quality.

  Characteristics of Different Types of Boiler Grates

  The types and structural forms of boiler grates mainly include three categories: chain grate, slat grate, and beam grate.

  1. Chain GrateBoiler GrateCharacteristics of Function

  The name comes from its shape, which looks like a chain belt, forming a wide circular chain belt linked together. The chain belt is supported and revolves around the front and rear axles through sprockets. Therefore, it is called a chain grate. Currently, the Zhongzheng boiler quick-install chain grate boiler mainly uses large block chain grates, with a tonnage range of 1 to 20 tons/hour.

  2. Characteristics of Slat Boiler Grate

  The slat grate has many advantages, among which the most obvious is that it has less coal leakage, slats can be replaced without stopping the furnace, ventilation is uniform, the ventilation cross-section is relatively small (6%), the slats are not stressed by high temperatures, and the chains under tension are not affected by high temperatures, improving the working conditions of the chain grate.

  3. Characteristics of Beam Boiler Grate

  The main feature of the beam boiler grate is that it can greatly expand in width and length, allowing for larger boiler tonnage. Currently, domestic beam boilers can reach a tonnage of 240 tons/hour. At the same time, this grate has a long lifespan, is durable, arranged neatly, and is easier to replace.
