What is biomass gasification?

In short, biomass gasification modern technology makes use of biomass as basic materials, oxygen, heavy steam or hydrogen as agent, as well as transform the biomass into combustible gas through chemical reaction at high temperature. The combustible gas can be utilized in commercial as well as farming production, such as power generation, supplying warm, methanol and ethanol synthesis. Biomass gasification is a convenient method to take advantage of biomass, and capitalize on the tidiness of the biofuel.



Biomass gasification power generation

Biomass gasification power generation includes 3 procedures. Biomass gasification is to change biomass into gas fuel. Gas purification is to eliminate the pollutants like ash, coke and tar in the gas with a purification system. Gas power generation is to burn the gas fuel in a gas turbine or an inner combustion engine. To boost the power generation performance, the biomass gasification nuclear power plant is outfitted with a heat recuperation central heating boiler as well as a vapor wind turbine.



The process of biomass gasification

The raw materials for biomass gasification are different, consisting of wood handling waste, agriculture residues. Such as sawdust, branch, plant straw, rice husk, corncob, etc. The product source is abundant as well as simple to obtain.



The gasification procedure is accomplished in the gasifiers. The reaction procedure is made complex, which varies with the sort of gasifier, the response problem, the features of basic materials, the grinding size. Yet they all include the following processes.



The raw products are shed in 4 layers: oxidation layer, reduction layer, thermal decay layer and also drying out layer. The reduction layer is one of the most important part that affect 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 shed as well as gasified right into combustible gas. The gasifiers can be identified into dealt with bed gasifier as well as fluidized bed gasifier.



Dealt with bed gasifier includes straightforward framework, reduced financial investment, as well as easy operation. It has less requirement on the size and sort of the raw material, but the gas production is tiny. Repaired bed gasifier appropriates for tiny gasification plant. Just up-flow type taken care of bed gasifiers appropriate for large range plant.



Fluidized bed gasifier has high heat transmission effectiveness and also high gasification strength. It has high gas generation price, appropriate for large and middle scale manufacturing. It is an efficient method to recognize the cycle of biomass gasification-- gas turbine generator-- heavy steam wind turbine generator. But it calls for higher expense as well as complicated feeding procedure.



Functions of biomass gasification power generation

Biomass gasification has actually become the most economical power generation method among all renewable energy innovation. animal pellet feed machine has actually come close to the level of power generation with traditional energy resources.



High flexibility

The gasified biomass can be applied in interior combustion engine, gas generator, or incorporated with warmth recovery boiler and also heavy steam boiler. You can select an ideal one according to the range of your power plant to accomplish high power generation effectiveness. The versatility can satisfy the decentralized utilization of biomass energy.



High cleanliness

Biomass is a type of renewable energy. It can reduce the exhaust of carbon dioxide, SO2 as well as various other damaging gas. The gasification process is performed at reduced temperature, so the NOX generation is reduced.



Cost-efficient

The versatility of gasification power generation guarantees the economic advantages in small scale manufacturing. The gas power generation process is straightforward, the devices is small, so it requires reduced financial investment than various other renewable resource power generation.



The background and also existing situation of biomass gasification

The biomass gasification innovation has actually been greater than 100 years. The initial biomass gasifier appeared in 1883. It utilizes timber charcoal as resources, as well as the fuel gas to drive the inner flammable engine in the auto or agricultural equipment. The flourishing of biomass gasification is during the second world war, when all fuel oil is used in battle as well as the residential fuel is in brief. Some nations developed automobile gasifiers that match with the automobile engine.



After the second war, owing to the exploration of oil in the middle-east area, the majority of developed nations make use of oil as their main power resource. The biomass gasification innovation has actually long gone stale. After richi pellet mill in 1973, a growing number of countries recognized the nonrenewable fuel source is non-renewable as well as not evenly dispersed. Biomass gasification reclaims the globe's interest as a mew energy innovation.



With years of development, biomass gasification modern technology has made excellent progression in Europe as well as America. Nowadays, the biomass gasifiers have attained high atomicity as well as advanced strategy. They are utilized for warmth supply, power generation, and fluid fuel synthesis. Sweden, Denmark, Austria, Germany, America and also Canada take the leading location in biomass gasification innovation. They have attains large commercial procedure.




The application prospect of biomass gasification

In terms of power matching, biomass is the world's fourth largest energy source after coal, oil and gas. Of the world's overall energy intake, the biomass accounts for 14%, and even over 40% in establishing countries.



Professors predict biomass energy will play a fundamental part in the future. Nowadays, lots of nations take measures to change the power portfolio, and offer concern to development of biomass power. In Europe, the biomass energy takes up 15% of the complete energy consumption. It is forecasted that biomass power will fill in 20% nonrenewable fuel source. An increasing number of biomass plants will go into operation in Europe, America, Canada as well as Japan in the future.
