Guide: Biomass boiler material comes from universal sources and is a renewable clean energy. It has almost no sulfur content and low ash content. It can digest and absorb all the CO2 caused by the whole process of ignition during the whole process of growth and development.

  Biomass boilers come from common sources and are renewable clean energy sources. They have almost no sulfur content and low ash content. The entire process of growth and development can digest and absorb all CO2 caused by the entire process of ignition, and achieve zero CO2 emissions. Bioenergy will gradually replace coal and become one of the key power sources. Biomass includes straw, wood branches, bamboo production and processing waste, grain shells, fruit stones, sugar residue, oil residue, etc. According to its specifications, it can be divided into three types: crumbs (≤2mm), flakes (≤50mm), and blocks (>50mm).

  Structural features

  The furnace wall is composed of arched cylinders and threaded smoke pipes, so that the furnace wall is changed from a quasi-rigid body to a standard polyurethane elastomer structure. The bracing parts in the cylinder area are eliminated and the ground stress is reduced. The exhaust pipe in the cylinder is changed from two reciprocating to single reciprocating, which solves the difficulty of cracks in the cylinder.

  Because of the layout of the raised pipe row under the furnace wall, the muddy water area at the bottom of the furnace wall is cleared, so that the sludge is not easy to accumulate, and the furnace wall powder layer can obtain excellent refrigeration, preventing the bag from under the furnace wall.

  The use of heat-conducting threaded smoke pipes has achieved the practical effect of enhancing heat conduction, achieving the characteristics of rapid temperature rise and pressure change of the heating furnace, and improving the heating efficiency of the heating furnace. The structure is compact, compared with the same type of heating furnace, the size is small, and the boiler room infrastructure investment is saved.

  Smooth operation, convenient adjustment and sufficient load rate.

  The threaded smoke tube is used to enhance the heat conduction and improve the thermal conductivity and thermal efficiency, because the smoke and dust in the tube have an oscillating effect. Dust is not easy to accumulate in the exhaust pipe and has the effect of self-cleaning.

  The horoscope wall in the furnace and part of the smoke window at the entrance and exit have a certain dust removal effect. The initial dust concentration value of the heating furnace is manipulated below the specification to ensure that the dust discharge of the heating furnace meets the national environmental protection requirements.

  The distinctive two-layer secondary air design scheme has improved the biomass fire standard, and a separate air chamber is selected to achieve effective air distribution, so that an aerodynamic field beneficial to ignition is generated in the furnace, which promotes high ignition temperature, Ignite high efficiency.

  Biomass fuel forming material shows

  Biomasspelletor Biomass Moulding Fuel (BMF, commonly known as “BMF”) is made from agricultural and forestry waste materials (such as straw, wood residue, bagasse, etc.) as raw materials. After crushing, air drying, mixing, extrusion molding and other production processes, Formed materials (such as pellets, rods, small pieces, etc.). The key is to replace the traditional #### energy (coal, oil, gas), a new type of clean fuel that is immediately ignited in the biomass fuel burner for professional new product development.

  1. The composition of BMF

  BMF is composed of flammable substances, inorganic compounds, and moisture. The key elements include carbon (C), hydrogen (H), oxygen (O), a small amount of nitrogen (N), sulfur (S), and other elements. Ash and moisture. Various ingredients consist of the following:

  ▲Carbon: BMF fuel is a low-carbon environmentally friendly fuel, with low carbon content (approximately 45-50%), especially when the fixed carbon content is low (approximately 16%), so low carbon emissions when ignited .

  ▲Hydrogen: BMF material contains a lot of hydrogen (about 5-8%) and high volatile content (over 70%), so it has good ignition characteristics.

  ▲ Oxygen: BMF material has high oxygen content (about 35-40%). The oxygen content of biomass significantly exceeds that of mineral coal, which facilitates the ignition of biomass.

  ▲Sulfur: The sulfur content in the BMF material is lower, and the environmental protection characteristics are good. There is no need to set the flue gas denitrification equipment when it is ignited.

  ▲Ash: The key to BMF pellet fuel is to use high-quality wood-based biomass fuel as the raw material. The ash content is low, only.

  2. The calorific value of biomass fuel forming material BMF

  The calorific value of biomass fuel forming material BMF is 15-19MJ/Kg, about 2~3kg BMF replace 1Kg light fuel oil or 1 cubic gas.

  3, the characteristics of biomass fuel forming material BMF

  ▲As a high-quality homogeneous material, the formed material can automatically control the system at the transportation, storage, transmission system and ignition levels, and its convenience level can be comparable to that of light gasoline and diesel;

  ▲ Fuel methanol, high density, small size, convenient storage safety, clean and tidy;

  ▲The material has high volatile content, easy to catch fire, good ignition characteristics, and high burnout rate;

  ▲The sulfur content is extremely low, only about 1/20 of that of light fuel oil, and environmental protection regulations can be met without any desulfurization and dust removal measures;

  ▲Low ash content, the basic dust removal device can consider environmental protection regulations;

  ▲Sewage discharge: The CO2 that biomass fuel ignites and discharges is the same as the CO2 digested and absorbed during the whole process of growth and development, which reduces net pollution. According to the "Kyoto Protocol" system, biomass CO2 is a green ecological pollution.
