Industrial boilers are widely used energy equipment in industrial production, and they are widely used in industries such as food, chemical, papermaking, rubber, and hospitals, with a variety of types. Reciprocating grate boilers are also widely used in the boiler industry. Considering that many users may be unfamiliar with this type of boiler, here, let me explain the principle and common types of reciprocating grate boilers.
Principle of Reciprocating Grate Boiler:
The principle of a reciprocating grate boiler is that the fuel is transported (elevated) by a feeding machine to the front hopper, and then it falls onto the screw feeding mechanism, which pushes it onto the grate. Through the reciprocating movement of the grate, the fuel gradually moves from the front to the back of the furnace, allowing the fuel to burn more fully.
Characteristics of Reciprocating Grate Boiler:
The reciprocating grate boiler manufactured by Taihu Boiler has the following advantages:
1) The principle of the reciprocating grate boiler makes it particularly suitable for burning biomass pellets and low-quality coal, not only achieving stable combustion but also meeting the design parameters smoothly.
2) The fuel combustion is more complete, and the thermal efficiency of Taihu biomass reciprocating grate boilers can reach over 88%.
3) The grate of the reciprocating grate boiler has the characteristics of a simple structure, easy manufacturing, low metal consumption, and good smoke removal and dust removal effects.
4) Various measures are taken to effectively avoid ash accumulation and coking in the boiler, thereby achieving strong continuous operation capability.
5) Taihu biomass reciprocating grate boilers solve the problem of high-temperature and low-temperature corrosion caused by biomass entering the furnace, greatly extending the service life of the equipment.
6) The Taihu reciprocating grate boiler has excellent dynamic response capability, easy start-up, and fast load increase and decrease rate.
7) Advanced control system with high degree of automation for fuel supply, ash removal, and slag discharge operations.
