Brief Intro：

SZL double drum chain grate boiler has the characteristics of high automation level, safe and efficient operation, and convenient installation. The design of this type of boiler is optimized, the problem of coking is solved, the thermal efficiency is significantly improved.

Introduction：

The SZL series chain grate boiler uses coal or biomass as a solid fuel. The water-cooled walls on both sides adopt a membrane-type water-cooled wall structure; the water-cooled wall tubes of the front and rear walls extend down to the upper part of the grate to form front and rear arches, which not only increases the sealing performance of the boiler, but also increases the furnace volume and heating surface. To some extent, reinforced the strength of the rear arch.

SZL series chain grate boilers have high automation level, safe and stable operation, strong fuel applicability, and high dust emission standards. The front wall is arranged with secondary air, which is controlled by a valve, and is put into use when biomass fuel is burned to strengthen combustion, so that the fuel can be fully burned out.

(1) The characteristics of the boiler operation are stable and have a certain overload operation capacity;

(2) The matching of the front and rear arches is reasonable, the coverage of the furnace arch is large, the furnace temperature is high. In addition, the coal can burn when the combustible volatile matter is greater than 20%;

(3) The air volume required by each air chamber can be adjusted according to the fuel combustion stage, and the lateral wind pressure is consistent.
