What Is The Process Of Biomass Pyrolysis Furnace?

With the increasing prominence of global environmental problems and the challenge of energy shortages. Therefore the interest of renewable energy sources is greatly valued. Among the various renewable sources. Biomass energy has a wide range of sources and a low carbon footprint. Therefore it has received attention. Biomass pyrolysis furnace is an important process for biomass energy conversion. Biomass energy sources include: wood, waste, coconut shells, fruit shells, straw, rice husk, sawdust and so on.

Biomass Pyrolysis Furnace Working Principle: It mainly involves the pyrolysis of biomass raw materials in a high temperature, oxygen-poor environment. Biomass is converted into solid carbonaceous products and combustible gases through high temperature under high temperature conditions. Biomass heated to high temperatures, in the absence of oxygen in the environment is not its complete combustion occurs. This leads to the gradual decomposition of the organic matter in the organism. This produces: tar, acetic acid, water and other liquid products. In the process of pyrolysis, a large number of flammable gases are released. For example, methane and carbon monoxide. The solid carbon products produced during the pyrolysis process are further heated. The residual volatiles are removed. This increases the fixed carbon content of the char. The biomass has a high calorific value and stability.

What is the process of biomass pyrolysis furnace?

Pre-treatment: The biomass raw material is firstly crushed into appropriate size particles by crusher. Then the moisture in the material is removed through drying. By drying the biomass particles are more evenly heated. Reduce the consumption of water evaporation in the pyrolysis process.

Pyrolysis: In the pyrolysis furnace, the fuel layer can be divided into drying layer, pyrolysis layer and reduction layer. Biomass raw material into the gasification device first in the first layer for drying. The material layer falls down, as the temperature produces higher. The volatiles in the biomass will gradually decompose. Thus sending cracking at high temperature.

Cracking: complex organic matter in the biomass feedstock decomposes at high temperatures. This produces liquid products such as tar, acetic acid and water. It also produces a large number of flammable gases. For example: CH4, CO, H2 and so on. At the same time it can also produce solid carbon products, biomass charcoal.

Redox: The pyrolysed gas and biomass char send oxidation reaction and combustion in the oxidation layer of the gasification layer and the supplied gasification medium. The combustion releases heat for sustaining the drying, pyrolysis and reduction reactions. The gas passes through the reduction layer to reduce its content through reduction reactions. The final product: a mixture of CO, H2, CH4 and partially unsaturated hydrocarbons CmHn.

Finished product collection: The solid product biomass char is collected by discharging it. The combustible gases generated during the pyrolysis process are cooled and collected. The heat required for the pyrolysis furnace can be recycled. Energy self-sufficiency is achieved. The rest of the gas can also be used as fuel after purification. For example, to generate electricity and heat.
