Introduction

Product Tags

Chain grate boiler is a kind of horizontal three return water fire tube hybrid boiler, in which a bunch of threaded smoke pipes are arranged in the drum.

The two sides of the furnace are equipped with smooth tube water wall. Light chain grate is used to realize mechanical coal feeding, blower and induced draft fan are equipped for mechanical ventilation, and scraper type slag extractor is installed to realize automatic slag discharge.

New energy-saving technology is adopted in the front and rear arches of the furnace. The fuel falls on the grate from the coal hopper and enters into the furnace for combustion.

After the flame is refracted upward through the back arch, it turns to the front smoke box through the burning out chambers on both sides of the body, and then turns back to the tube bundle in the boiler from the front smoke box, and then enters the economizer through the rear smoke box, and then is pumped by the induced draft fan to the chimney and discharged to the atmosphere.
