Product Introduction:

The SZL double drum longitudinal chain grate boiler adopts a double drum longitudinal arrangement, and the boiler burns biomass formed solid fuel. The water-cooled walls on both sides of the furnace adopt a membrane water-cooled wall structure; The water-cooled wall tubes on the front and rear walls of the furnace extend downwards to the upper part of the grate, forming front and rear arches. This not only increases the sealing performance of the boiler, but also increases the furnace volume and heating surface, while reinforcing the strength of the rear arch. The fuel falls from the coal hopper onto the grate and is burned after entering the furnace with the grate. The flue gas enters the convection tube bundle area and passes through the smoke wall. The flue gas flows towards an S-shaped bend and uses inertia to separate the dust in the flue gas, which then falls into the four gravity type automatic ash hoppers set below. It then moves with the grate and falls into the slag hopper, where it is discharged from the furnace body by the slag extractor.

Application scenarios：

This boiler is widely used in hospitals, schools, hotels, government agencies, pharmaceutical industry, food factories, beverage factories, rubber factories, greenhouses, chemical industry, paper mills, building materials industry, clothing and textile factories, washing plants, etc

Our Advantages：

(1) High thermal efficiency The boiler adopts a convective arrangement, with high heat transfer efficiency on the heating surface. The efficiency characteristics of the boiler operation are stable and have a certain degree of overload operation capability (2) Reasonable water circulation system Reasonable water circulation system, large water capacity, ample steam space, and good steam quality; (3) Stable combustion The cross-sectional ratio between the descending surface and the ascending pipe of each heating surface is reasonable, and the combustion conditions are stable; (4) High furnace temperature Reasonable matching of front and rear arches, high coverage of furnace arches, high furnace temperature, and the ability to burn coal with combustible volatiles greater than 20% (5) Adjustable air volume Each air chamber can be manually adjusted according to the required air volume for each combustion stage of the fuel, and the lateral air pressure is consistent, so there will be no phenomenon of partial combustion (6) Good sealing performance Each air chamber is equipped with a pull-out cast iron ash discharge door at the bottom, which is not easily deformed, easy to use, and has good sealing performance
