How to maintain a reciprocating grate?

　　The reciprocating grate consists of two parts: the grate frame and the grate plates, which are usually cast from cast iron. After assembly, it is necessary to maintain a ventilation gap between each piece, and a separate ventilation chamber is usually set up below the grate, with adjustable air volume, so that air can enter the fuel layer for combustion through the gaps, and the ash after combustion can be discharged manually or mechanically. There are fixed grates, moving grates, vibrating grates, and feeding grates.Reciprocating Gratevibrating grate and feeding grate.

　　In the process of municipal solid waste incineration, various influencing factors should be reasonably controlled under possible conditions, so that their comprehensive effects develop in a direction favorable to the complete combustion of municipal solid waste. At the same time, it should be recognized that these influencing factors are not isolated; there is an interdependent and mutually restrictive relationship between them. The positive impact of one factor may lead to the negative impact of another factor. Therefore, the control of factors in the entire combustion process should be considered from the perspective of comprehensive effects. In particular, the government needs to take active incentive measures to ensure the healthy development of the municipal solid waste incineration power generation industry.

　　Using lightweight chain grates to achieve mechanical coal feeding, equipped with blowers and induced draft fans for mechanical ventilation, and equipped with scraper ash discharge machines for automatic ash discharge.Reciprocating GrateThe front and rear arches adopt new energy-saving technologies. After the fuel falls from the coal hopper onto the grate and enters the furnace for combustion, the flame is refracted upward through the rear arch, turns towards the front smoke box through the ash chambers on both sides of the furnace body, and then returns from the front smoke box to the boiler tube bundle, entering the economizer through the rear smoke box, and then being drawn in by the induced draft fan, discharged through the flue to the chimney.

　　Main maintenance considerations for the reciprocating grate:

　　1. Check the performance of the boiler pressure gauge, water level gauge, safety valve, sewage device, water supply valve, steam valve, etc., to see if they meet the requirements, and whether other valves are in good switching condition. Reciprocating grate

　　2. Whether the boiler water level and water tank temperature meet the requirements.

　　3. The conditions of the boiler fuel combustion system, including fuel reserves, transmission lines, combustion equipment, ignition equipment, fuel cutoff devices, oil pumps, etc., should meet the symbol requirements.

　　4. The boiler ventilation system, including fans, induced draft fans, regulating valves and damper openings, ventilation ducts, etc., should be intact. Reciprocating grate

　　For waste with different calorific values, different air volumes are allocated to supply combustion air. At the same time, the drive of each grate can be controlled independently, facilitating the separate control of feed amounts and air volumes in different combustion areas. An overlapping structure is set between each row of grate bars to prevent waste from leaking from adjacent bars, and there is almost no friction between the same row of grate bars; to reduce wear and improve the service life of the grate, elastic wear-resistant scrapers are set in front of the grate blades. The bottom of the grate plate is equipped with cooling steel plates, which have good cooling effects with primary air, making it difficult for the grate to burn.

　　Reciprocating GrateThe structure and movement mode are simple, not easy to block, with a low failure rate, saving a lot of maintenance costs. The grate is replaced starting from the fourth year, with an annual replacement rate of less than 2%. The modular structure of the grate section is conducive to road transportation and on-site installation. It can be fully assembled in the workshop, improving the precision required for on-site installation.
