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.

Ⅱ, biomass fuel composition

(1) Agricultural biomass molding fuel
Corn stalk, wheat stalk, straw, bean stalk, sorghum stalk, cotton stalk and other crop straw produced in the process of agricultural production

(2) Agricultural product processing industry leftovers
Residues such as rice husks, corn cobs, peanut husks and other residues produced in the processing of agricultural products are agricultural mixtures and mixtures of various agricultural biomass

(3) Forest biomass fuel
Felling, timber building residues, wood processing residues, tree pruning and forestry mixtures

(4) Mixed biomass fuel
A mixture of agricultural and forestry biomass

Ⅲ, Characteristics of biomass fuel

1. Biomass molding fuel, with easy ignition, good fuel performance, high calorific value, no pollution, after combustion can meet GB13271 "boiler air pollutant emission standard" requirements.
2. Biomass molding fuel, with a significant ratio (1000-1270kg /m3), high calorific value (3800~4500Kcal/kg), volatile content ≥65.6%, combustion rate of more than 90%. Low cost, easy to use, clean and sanitary advantages, easy to store and transport.
3. Biomass molding fuel, a renewable and clean fuel, is a typical circular economy project.
4. Low-carbon energy CO2 zero emissions, biomass fuel is mainly volatile, its fixed carbon content is only 15% on the right, is a typical low-carbon fuel. The CO2 emitted by combustion is absorbed by plants for photosynthesis during the growth process to achieve zero CO2 emission.
5.Low nitrogen and sulfur content reduces sulfur dioxide (SO2) and NOx oxide emissions. The sulfur content of biomass is only 0.06%, which is lower than the sulfur content of light diesel, and it can be directly discharged without the need to set up a desulfurization device.
