Product Discription
WNS Series Horizontal Biomass Gas Fired Steam Boiler
WNS series horizontal biomass gas fired steam boiler is fast loading structure, internal combustion, three-pass fire tube boiler, use offset wet back structure, high temperature flue gas scour second-pass and third-pass fire tubes one after another, and then discharge into atmosphere from back smoke box and chimney. Boiler equip with mobile front and back smoke box cover, convenient maintenance.
Product Features
1. Installation convenience:
The boiler is generally fast-loading factory, easy to transport and on-site installation, greatly shorten the construction cycle, save installation costs, so that the boiler can be put into production in time.
2.Reliable operation:
Boiler heating surface layout is reasonable, water circulation is smooth, and each heating surface is cooled in time, so as to effectively ensure the safe operation of the boiler.
3.Maintenance and repair convenience:
Boiler drum set up manhole, can enter inspection repair. It is convenient to open the smoke box in front of the boiler, and the personnel can check it easily and clearly, which provides a good condition for correct treatment.
4.Full combustion:
With the secondary air and reasonable furnace design, the fuel can be fully burned and the black smoke can be eliminated.
5.High efficiency grate:
Boiler grate adopts double side ventilation, which is brought naturally to the front end of boiler row by dust cleaning technology, which avoids air leakage, fuel leakage and uneven ventilation, and is easy to operate, and has obvious advantages compared with ordinary grate.
6.Convenient ash cleaning:
Many ash cleaning holes can be set up on the boiler, which can remove ash in time and effectively, avoid the trouble of operation and decrease of thermal efficiency caused by boiler ash accumulation, and ensure the stability of boiler load.
