Advantages technical features

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.

Recommend  gas oil water tube boiler & vertical water tube boiler:

1) Vertical water tube boiler, 100kg-2000kg steam boiler, 100kw-1400kw hot water boiler, it cost small occupy area of vertical type, suitable small capacity, low cost and long lifespan.
