Brief Introduction 

SZL Series Biomass Chain Grate Boiler adopts double-tub vertical arrangement, and the combustion method is chain grate.The rated evaporation is 4~20t/h.This biomass boiler fired with biomass solid fuel.Biomass fuel is more economical for the worldwide customers. And this fuel has become very popular in the world.The SZL Series Biomass Chain Grate Boiler with high boiler efficiency, strong overload capacity and wide coal adaptability, it is famous as the best design scheme for similar domestic products in the world and it has advanced world level technology.

Features and Advantages of SZL Series Biomass Chain Grate Boiler

1.The membrane water wall structure used for power station boilers is applied to the assembly boiler, the advantages of this design are as follows: large heat transfer area, good conduction effect, low heat loss, good airtightness, no deformation of the furnace wall, and no leakage of ash.
2.The front and rear water wall pipes of the hearth extend downwards to the upper part of the grate to form the front and rear arches, increasing the radiant heat surface of the hearth, and the overload capacity is stronger; the front and rear arches are made of water-cooled wall tubes as the skeleton and casted with high-alumina cement, avoiding the defects of fractures and arches collapsed, prolonging the service life of the arches.
3.The length of the front and rear shafts of the grate is longer than that of domestic products of the same model, prolonging the burning time of the fuel in the furnace, so that the combustion of the coal is sufficient, the carbon content of the slag is reduced, the effective area of the grate is increased, and the boiler overload capacity is obviously enhanced.
4.Six independent wind chambers are arranged along the longitudinal direction of the grate. There is an independent air adjusting device between each air chamber to adjust the air volume of each air chamber to achieve the best adjustment of the combustion effect.

Application:

It is mainly used for heating supply in winter, central heating supply and industrial process steam supply.
