Coal-fired hot water boiler

describe

characteristic

This product is a new type of product independently developed by our company, with a unique and innovative structure. Adopting double-layer grate reverse combustion and multi horizontal fire tube structure, equipped with induced draft fan for negative pressure combustion. This product is suitable for various purposes in enterprises, institutions, military, and service industries. It was rated as an excellent new product by the Zhejiang Environmental Protection Association in 1994; In 1996, it was awarded the third prize for scientific and technological progress by the Shanghai Railway Bureau. It has the following characteristics:

The volatile matter burns completely without black smoke;
Novel structure and high thermal efficiency;
Induced negative pressure combustion with sufficient output;
High smoke velocity and fast heat transfer;
The process of flue gas in the furnace is long, and the exhaust temperature is low.
