What is biomass gasification?

Briefly, biomass gasification innovation makes use of biomass as basic materials, oxygen, steam or hydrogen as agent, and turn the biomass right into flammable gas through chemical reaction at heat. The flammable gas can be made use of in commercial as well as farming manufacturing, such as power generation, supplying warm, methanol and ethanol synthesis. Biomass gasification is a practical way to utilize biomass, and make the most of the tidiness of the biofuel.



Biomass gasification power generation

Biomass gasification power generation consists of 3 processes. manual pellet making machine is to change biomass right into gas fuel. Gas purification is to get rid of the contaminations like ash, coke as well as tar in the gas with a filtration system. Gas power generation is to burn the gas fuel in a gas generator or an inner burning engine. To enhance the power generation efficiency, the biomass gasification power plant is equipped with a warm recovery central heating boiler and a vapor turbine.



The process of biomass gasification

The raw materials for biomass gasification are various, consisting of timber processing waste, farming residues. Such as sawdust, branch, crop straw, rice husk, corncob, etc. The material source is bountiful and also simple to get.



The gasification process is accomplished in the gasifiers. The reaction process is complicated, which differs with the kind of gasifier, the response condition, the functions of raw materials, the grinding dimension. However they all include the adhering to processes.



The raw materials are melted in 4 layers: oxidation layer, decrease layer, thermal disintegration layer and drying layer. The reduction layer is one of the most important part that influence the top quality and return of the gas.



What is biomass gasifier?

The core tools for biomass gasification is a gasifier, where the biomass is melted as well as gasified into combustible gas. The gasifiers can be classified into repaired bed gasifier and also fluidized bed gasifier.



Taken care of bed gasifier features simple structure, reduced financial investment, as well as easy operation. It has much less need on the size as well as sort of the raw product, yet the gas production is tiny. Fixed bed gasifier appropriates for tiny gasification plant. Just up-flow kind fixed bed gasifiers appropriate for huge scale plant.




Fluidized bed gasifier has high heat transmission performance as well as high gasification strength. It has high gas generation rate, ideal for large as well as center range production. It is an effective way to realize the cycle of biomass gasification-- gas turbine generator-- vapor wind turbine generator. However it requires higher cost and complex feeding process.



Functions of biomass gasification power generation

Biomass gasification has become the most affordable power generation method amongst all renewable energy technology. It's thorough expense has come close to the level of power generation with standard power resources.



High adaptability

The gasified biomass can be applied in inner combustion engine, gas turbine, or combined with warm recuperation central heating boiler and steam central heating boiler. You can pick an appropriate one according to the range of your power plant to accomplish high power generation performance. The adaptability can satisfy the decentralized use of biomass power.



High tidiness

Biomass is a kind of renewable resource. It can minimize the emission of carbon dioxide, SO2 and also other hazardous gas. The gasification procedure is performed at reduced temperature, so the NOX generation is low.



Affordable

The flexibility of gasification power generation guarantees the financial benefits in little range manufacturing. The gas power generation procedure is easy, the tools is compact, so it requires reduced financial investment than other renewable energy power generation.



The background and existing scenario of biomass gasification

The biomass gasification innovation has been greater than 100 years. The first biomass gasifier showed up in 1883. It uses wood charcoal as raw material, and the fuel gas to drive the interior combustible engine in the auto or agricultural equipment. The prosperous of biomass gasification is throughout the 2nd world war, when all gas oil is used in war as well as the domestic gas remains in short. Some nations developed car gasifiers that match with the auto engine.



After the second war, owing to the exploration of oil in the middle-east area, many developed countries use oil as their primary power source. The biomass gasification technology has actually long gone stale. After the power dilemma in 1973, an increasing number of countries understood the nonrenewable fuel source is non-renewable and not evenly distributed. pellet making machine price reclaims the globe's focus as a mew energy technology.



With years of advancement, biomass gasification technology has actually made wonderful progress in Europe and America. Nowadays, the biomass gasifiers have actually accomplished high atomicity and also advanced strategy. They are used for warm supply, power generation, and liquid fuel synthesis. Sweden, Denmark, Austria, Germany, America as well as Canada take the leading place in biomass gasification technology. They have attains large-scale industrial procedure.



The application prospect of biomass gasification

In terms of power equivalent, biomass is the world's fourth largest power source after coal, oil and also gas. Of the world's complete power usage, the biomass make up 14%, and also even over 40% in creating nations.




Professors anticipate biomass energy will certainly play an integral part in the future. Nowadays, lots of countries take measures to change the energy portfolio, and also provide priority to development of biomass power. In Europe, the biomass energy takes up 15% of the total power usage. It is forecasted that biomass energy will take the place of 20% nonrenewable fuel source. More and more biomass plants will certainly go into procedure in Europe, America, Canada and also Japan in the future.
