Introduction of wood fired industrial water tube szl steam boiler

The SZL series quickly installed coal/biomass fired steam boiler is the most advanced water-fire tube boiler in worldwide market and foreign market,this series boiler can be used in textile,food and corrugated box factory with high efficiency, small in size and long working life.

The coal/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 series boiler 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.

Main Features of wood fired industrial water tube szl steam boiler

1. By adopting the water-cooling system in packaged boilers which is usually used in power plant boilers, the boiler can achieve large heat transfer area, high heat transfer efficiency, low heat loss, good air tightness, and no distortion or dust leakage of the brickwork.
2. The front and back water-cooling wall tubes stretch themselves to the upper side of the chain grate, which increases the heating surface and overload capacity. The frames of the front and the rear arch are made of water-cooling tube wall, together with high-alumina cement, which can avoid the defects of the cracking and collapsing of the arch and extend its lifespan.
3. The distance between the front shaft and the rear shaft of the grate stoker is longer than other similar type domestic products. In this way, the combustion time of the fuel in the furnace is extended and the fuel combustion is more sufficient and the carbon content in the slag is decreased. Meanwhile, the actual heating surface of the grate is increased and the overload capacity is remarkably enhanced.
4. There are six independent wind chambers arranged lengthways and each chamber has an independent air adjuster, which can respectively adjust the air volume in each chamber so as to achieve the best combustion effect.

Machine Parts

Name: Chain Grate

Brand: Sitong

Original: China

The scale chain grate boiler could resist the temperature as high as 1200℃, long working life. It has a low coal leakage because of the small gap. High automatic degree, decrease labor cost. Convenient for maintenance, it could be done without boiler shut down.

Main Features

Name: Economizer
Brand: Sitong
Original: China
Economizer is the boiler tail flue in the boiler feed water heated to the steam pressure under the saturated water heating surface, because it absorbs relatively low temperature flue gas, reducing the smoke exhaust gas temperature, saving energy, improve the efficiency.

Machine Parts

Name: Threaded Smoke Pipe
Brand: Sitong
Original: China
The boiler use spirally corrugated tube, the thermal transfer efficiency is high. The texture of it is 20# steel, it belongs to low-carbon steel, has high tenacity.
