Introduction of steam boiler

WNS series steam boiler is specially designed and developed a new generation dedicated biomass fuel

boilers based on the characteristics of biomass fuels dedicated machine, equipped with the company developed

a special biomass burner.

Features of steam boiler

1. Fully automatic running:

once ignited, the boiler will run automatically according to setted process;

2. Unique structure:

According to the characteristics of biomass fuel machine, furnace uses the latest design and manufacturing

processes, eccentric furnace, wet back three return, heating area, high thermal efficiency.

3. Low-carbon and environmentally friendly:

with dedicated biomass burner, combustion safety, high combustion efficiency; soot emissions by dust treatment

full compliance with national standards; zero carbon dioxide emissions;

4. Good insulation properties:

the use of glass fiber insulation, low heat loss;

5. Easy inspection and maintenance :

all parts of the boiler design is reasonable; easy to inspect and repair
