6 Ton firewood biomass pellet fired steam boiler industrial boilers for sale
1. Product fuel characteristics
Our Biomass pellet-fired steam boileris closed mechanical equipment that uses biomass as fuel, generates
heat energy and converts heat energy in the process of combustion.
Yongxing Biomass pellet fired steam boiler is the most environmentally friendly and energy-saving boiler.
The amount of CO2 absorbed by biomass fuel during its growth is
basically equal to the amount of CO2 generated by combustion, and
it is a kind of renewable green energy with almost no sulfur
content.
In the next few years, biomass energy will gradually replace the
current use of coal products, become one of the main energy.
Biomass fuels come from a wide range of sources, including crop
straw, bamboo twigs, bamboo processing waste, rice husks, fruit
husks, bagasse and so on.
biomass pellet fired steam boiler fuel as follow pictures
According to the characteristics of loose and light biomass fuel,
the shape of the furnace is changed, the furnace volume is
improved, and the design of low flow resistance is designed, so as
to reduce the fan power and realize the purpose of energy-saving
and electricity saving.
According to the specific requirements of different fuels, the
company can set up a burner in front of the boiler to achieve
automatic feeding, reducing labor intensity, and improving
combustion efficiency.
2. Product structure features
