Guide: 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, achieving zero CO2 emissions.
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 husks, fruit stones, sugar residue, oil residue, etc. According to its specifications, it can be divided into three types: chips (≤2mm), flakes (≤50mm), and blocks (>50mm).
DZL series product biomass fuel chain grate gas steam boiler detailed introduction
available materials
This product uses chain grate, which can be used as formed pellet fuel, a small amount of wood, blocks, or mixed with coal.
Structural features
The arched cylinder and the threaded smoke tube are used to form the furnace wall, 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 cooling and prevent the bag from under the furnace wall.
The use of heat-conducting threaded smoke tubes has achieved the practical effect of enhancing heat conduction, achieving the characteristics of rapid temperature increase and pressure change of the heating furnace, and the heating efficiency of the heating furnace is improved. The structure is compact, compared with the same type of heating furnace, and the size is small, saving the investment in the infrastructure of the boiler room.
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 duct and has the effect of self-cleaning.
The eight-character 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 controlled below the specification, which ensures 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
Biomass fuel forming fuel (Biomasspelletor Biomass Moulding Fuel, commonly referred to as "BMF") is made by using agricultural and forestry waste (such as straw, wood residue, bagasse, etc.) as raw materials, through production processes such as crushing, air drying, mixing, and extrusion molding. 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 biomass fuel forming material BMF
BMF is composed of flammable substances, inorganic compounds and moisture. The key elements include carbon (C), hydrogen (H), oxygen (O) and a small amount of nitrogen (N), sulfur (S), etc. 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 denitration 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, and replaces #### energy, reducing net pollution. According to the "Kyoto Protocol" system, biomass CO2 Discharge sewage for green ecology.
