Massive and universal:Straw is a ubiquitous and inexpensive energy source that is easy to obtain and has a simple production process.

Reproducibility:Straw biomass energy is an ideal renewable energy source. As long as crops are grown, straw biomass energy will never be depleted.

Environmental friendliness:Using straw as energy can reduce environmental pollution. The rotting of straw piles can pollute the environment, breed bacteria, mosquitoes, and produce harmful and odorous gases such as hydrogen sulfide and methane, which not only occupy land resources but also pollute the environment.

Cleanliness:Using straw to generate electricity utilizes organic matter within plants, and the carbon dioxide emitted by the system is absorbed by the next season's plant growth. Therefore, it does not increase the concentration of carbon dioxide in the atmosphere and can achieve "zero emissions" of carbon dioxide.

Low cost:Low cost does not mean that our company's equipment is cheap. Of course, compared to large power plant systems, the investment cost per unit of electricity in our company's equipment is still relatively low. Low cost mainly refers to the low cost of gas and electricity generated after biomass gasification, because straw is used as the raw material source, so the cost of raw materials will be extremely low, or zero cost, or even negative cost (some countries' customers receive subsidies when receiving these raw materials).

Air is blown into the side wall air nozzle of the gasifier, and the flow direction of the produced gas is consistent with the direction of material falling. Therefore, a down draft gasifier is also known as a co current gasifier. The air blown in is mixed with the material and burned, and this area is called the oxidation zone, with a temperature of about 900-1200 ℃. The heat generated is used to support the cracking reaction in the pyrolysis zone and the reduction reaction in the reduction zone; The upper part of the oxidation zone is the pyrolysis zone, with a temperature of about 300-700 ℃. In this zone, the volatile components (cracking gas, tar, and water) in the biomass are separated; The upper part of the pyrolysis zone is the drying zone, where the material is preheated; The lower part of the oxidation zone is the reduction zone, where CO2, carbon, and water vapor produced undergo reduction reactions. At the same time, residual tar undergoes cracking reactions in this zone, producing gas mainly composed of CO and H2. The temperature in this zone is about 700-900 ℃. The gas rich in tar from the pyrolysis zone must pass through a high-temperature oxidation zone and a reduction zone dominated by hot coke, where the tar is cracked at high temperatures, resulting in a significant reduction of tar in the produced gas.
