Water tube boilers are designed for larger, high-pressure, and superheated steam applications. Biomass fired water tube chain grate boiler is a good example. Membrane water cooling wall structure in combustion chamber, good sealing to prevent heat loss. It is widely used in textile factory, paper factory, food industry, generating steam in industry process. SZL series water tube boilers were sold to Iran, Mongolia and Vietnam.
Heating, hotels, schools, hospitals
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.
a.Longer fuel combustion period. Front arch is higher and shorter than rear arch, 45°angle between the two arches, which can extend the time of flue gas combustion time, and enhance thermal transferring efficiency.
b.Available to burn various biomass. It design can burn biomass fuels such as rice husk, wood, bagasse, straw, sawdust, sunflower shells, as well as low calorific value coal.
Wind is feed from both sides of the boiler. There are six independent air chambers, each of them has independent air adjustment device which can respectively adjust the air volume so as to achieve the best combustion effect.
The distance between the front shaft and the rear shaft of the grate stoker is longer than other similar type 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.
