Ⅰ, biomass molding fuel boiler

A boiler that burns biomass molding fuel to heat working medium.

Biomass molding fuel is the use of woody, herbaceous plants (such as straw, rice bran, wood chips, bark, peanut shell, hemp stalk, etc.) and their waste materials as raw materials, with mechanical methods (such as cutting, crushing), dense molding technology, processing into a shape and size, bulk density, conducive to transportation and combustion of molding fuel. It can replace coal, oil and natural gas, achieve energy saving and emission reduction, and greatly reduce production costs compared with oil or gas boilers.

Biomass fuel is a renewable clean fuel, the development of biomass energy instead of oil, coal and other traditional energy, reduce fossil fuel consumption, reduce CO², not only can protect the environment, but also promote the sustainable development of agriculture and forestry, with good ecological and social benefits.
