DZL type chain grate steam boiler is a kind of horizontal three-return water and fire pipe mixed boiler, which is arranged with a bunch of threaded smoke pipe inside the boiler barrel.The left and right sides of the furnace chamber are equipped with water cooling walls of light pipes.It adopts light chain grate to realize mechanical coal feeding, equipped with blower and induced draft fan for mechanical ventilation, and equipped with scraper type slag discharge machine to realize automatic slag discharge.The front and rear arches of the boiler adopt new energy saving technology.

After the fuel falls on the grate from the coal sill and enters the furnace for combustion, the flame, through the refraction of the rear arch, turns upward through the burning Chambers on both sides of the body and turns to the front smoke box, and then turns back to the tube bundle in the steam boiler by the front smoke box, enters the economizer through the rear smoke box, and then is pumped by the induced draft fan to the air through the flue to the chimney.

Performance Features:

1. The boiler thermal efficiency is above 77%, higher than the standard of "General Technical Conditions for Industrial Boilers".

2, the operation has achieved mechanization, reduce the labor intensity of the stoker.

3. Quick loading leaves the factory. After arriving at the service site, install and connect the valve instrument, drum, induced draft fan, smoke air pipe, economizer, dust collector and slag extractor.Coal loader and water and electricity road can run, and has the characteristics of starting a fire quickly.

4. Easy installation and movement can save a lot of capital investment.

5. Grade ii bituminous coal with lower heating value ≥17750J/Kg, volatile >38.5% and ash content ≤32.4%.

Boiler Accessory

DZL series quickly installed biomass fired steam boiler is the most advanced water-fire tube boiler in Chinese market, This series boiler can be used in textile, food and package factory with high efficiency, small in size and long working life.

The biomass fired steam boiler after improvement takes use of structure of wing type smoke duct, one-way screwed smoke tube, arched tube plate, smoke and gas separate room and several other advanced technology, which has increased the water circulation speed and safety factor. This boiler series is well designed, compactly made up, quickly installed, mono layer, so that the civil engineering and investment could be saved. With these improvement, the boiler's working life extend much to be the national energy saving product.
