The "Xineng" brand biomass fuel steam/hot water boiler can be used for forestry biomass, agricultural biomass, mixed agricultural and forestry biomass shaped fuels, and other types of fuels. Combustion equipment can adopt combustion types such as chain grate, reciprocating grate, and fixed grate. It can also be designed separately according to the customer's fuel needs.

Biomass Forming Fuel Boiler

A boiler that uses biomass formed fuel to burn and heat the working fluid.

Biomass formed fuel is a type of formed fuel that uses woody and herbaceous plants (such as straw, rice bran, sawdust, bark, peanut shells, hemp stalks, etc.) and their waste materials as raw materials. It is processed by mechanical methods (such as cutting and crushing) and dense forming technology to produce a certain shape and size, high bulk density, and is conducive to transportation and combustion. It can replace coal, oil, and natural gas, achieve energy conservation and emission reduction, and significantly reduce production costs compared to oil or gas boilers.

Biomass fuel is a renewable and clean fuel. Developing biomass energy to replace traditional energy sources such as oil and coal can reduce fossil fuel consumption and CO2 emissions. This not only protects the environment but also promotes sustainable development of agriculture and forestry, with good ecological and social benefits.

Classification of biomass fuels

• Agricultural biomass molding fuel
  The crop straw produced in the agricultural production process includes corn stalks, wheat stalks, rice straw, soybean stalks, sorghum stalks, and cotton stalks
  Surplus from agricultural product processing industry, including rice husks, corn cobs, peanut shells, and other residues generated during the processing of agricultural products
  A mixture of various agricultural biomass in agriculture
• Forest biomass fuel
  Harvesting and timber processing residues, timber pruning residues, forestry mixtures
• Mixed biomass fuel
  A mixture of agricultural and forestry biomass

Characteristics of Biomass Fuel

• Biomass formed fuel has the advantages of easy ignition, good fuel performance, high calorific value, no pollution, and can meet the requirements of GB13271 "Boiler Air Pollutant Emission Standard" after combustion.
• Biomass formed fuel has a specific gravity (1.0-1.27 kg/m3), high calorific value (3800~4500 kcal), volatile matter ≥ 65.6%, and a combustion rate of over 90%. Low cost, easy to use, clean and hygienic, and convenient for storage and transportation.
• Biomass formed fuel is a renewable clean fuel and a typical circular economy project.
• Low carbon energy with zero CO2 emissions, biomass fuel mainly consists of volatile matter, and its fixed carbon content is only about 15%, making it a typical low-carbon fuel. The CO2 emitted from combustion is absorbed by plants during their growth process for photosynthesis, achieving zero CO2 emissions.
• Low nitrogen and sulfur content can reduce the emissions of sulfur dioxide (SO2) and NO oxides. The sulfur content of biomass is only 0.06%, which is lower than that of light diesel, and can be directly discharged without the need for a desulfurization device.

Range

Rated evaporation capacity: 2-20t/h, rated pressure: 1.0-2.5MPa

Structural characteristics

• The boiler body adopts a double drum water pipe structure and a chain grate combustion method. The boiler drum is arranged longitudinally along the center of the boiler, with water-cooled wall tubes forming the radiation heating surface of the furnace, and the tube bundles between the upper and lower drums forming the convection heating surface. An economizer is arranged at the tail.
• Raise the grate combustion chamber and arrange lateral secondary air; Chain grate with separate compartments for air intake, independent adjustment of air volume, and stepless speed regulation of grate.
• The feeding device has independent intellectual property rights and adopts a locking mechanism.
• The radiation heat transfer surface and convection heat transfer surface of the furnace adopt special wear-resistant structures.
• The boiler has a compact overall structure, small footprint, high assembly level, short installation cycle, and low installation cost.
