What is biomass gasification?

Briefly, biomass gasification innovation uses biomass as raw materials, oxygen, heavy steam or hydrogen as agent, and transform the biomass into flammable gas through chain reaction at high temperature. The combustible gas can be used in commercial and also farming production, such as power generation, supplying warmth, methanol as well as ethanol synthesis. Biomass gasification is a convenient means to make use of biomass, and also make the most of the tidiness of the biofuel.



Biomass gasification power generation

Biomass gasification power generation includes 3 procedures. Biomass gasification is to change biomass right into gas fuel. Gas filtration is to eliminate the contaminations 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 enhance the power generation effectiveness, the biomass gasification nuclear power plant is equipped with a warmth recuperation boiler and a vapor wind turbine.



The process of biomass gasification

The raw products for biomass gasification are various, consisting of timber processing waste, agriculture residues. Such as sawdust, branch, crop straw, rice husk, corncob, etc. The material source is plentiful and simple to obtain.



The gasification process is executed in the gasifiers. The response procedure is complicated, which varies with the kind of gasifier, the reaction condition, the features of resources, the grinding dimension. Yet they all contain the complying with processes.




The raw products are burned in 4 layers: oxidation layer, reduction layer, thermal disintegration layer as well as drying out layer. The reduction layer is one of the most important part that influence the top quality and yield of the gas.



What is biomass gasifier?

The core devices for biomass gasification is a gasifier, where the biomass is melted and gasified right into combustible gas. The gasifiers can be categorized into dealt with bed gasifier and fluidized bed gasifier.



Taken care of bed gasifier features simple framework, reduced investment, as well as easy operation. It has less requirement on the dimension and also sort of the raw material, but the gas production is tiny. Dealt with bed gasifier appropriates for tiny gasification plant. Just up-flow type repaired bed gasifiers appropriate for huge range plant.



Fluidized bed gasifier has high heat transmission performance and also high gasification intensity. It has high gas generation price, ideal for huge as well as center scale production. It is an effective method to realize the cycle of biomass gasification-- gas wind turbine generator-- vapor turbine generator. However it calls for higher cost as well as complicated feeding process.



Features of biomass gasification power generation

Biomass gasification has become one of the most cost-effective power generation method among all renewable resource modern technology. It's comprehensive expense has come close to the degree of power generation with traditional power resources.



High versatility

The gasified biomass can be applied in inner combustion engine, gas wind turbine, or combined with heat recovery boiler and vapor central heating boiler. You can pick a suitable one according to the scale of your nuclear power plant to achieve high power generation performance. The flexibility can satisfy the decentralized use of biomass energy.



High sanitation

Biomass is a sort of renewable energy. It can reduce the discharge of carbon dioxide, SO2 and other hazardous gas. The gasification process is performed at low temperature, so the NOX generation is low.



Cost-effective

The flexibility of gasification power generation guarantees the financial benefits in tiny range manufacturing. The gas power generation procedure is simple, the tools is compact, so it needs low financial investment than other renewable energy power generation.




The history and existing circumstance of biomass gasification

The biomass gasification modern technology has actually been greater than 100 years. The first biomass gasifier showed up in 1883. It makes use of timber charcoal as resources, and the fuel gas to drive the internal combustible engine in the automobile or agricultural machinery. The thriving of biomass gasification is during the second world war, when all gas oil is used in war and also the domestic gas remains in short. Some countries established car gasifiers that match with the vehicle engine.



After the second war, owing to the expedition of oil in the middle-east location, most developed nations make use of oil as their main energy resource. The biomass gasification technology has actually long stagnated. After the energy dilemma in 1973, more and more nations understood the nonrenewable fuel source is non-renewable and not uniformly dispersed. gemco pellet machine reclaims the world's interest as a mew energy technology.



With decades of growth, biomass gasification technology has actually made terrific progression in Europe and also America. Nowadays, fish feed making machine low price have achieved high atomicity and progressed strategy. They are made use of for heat supply, power generation, and also liquid fuel synthesis. Sweden, Denmark, Austria, Germany, America as well as Canada take the leading location in biomass gasification modern technology. They have achieves large-scale industrial operation.



The application prospect of biomass gasification

In regards to energy equivalent, biomass is the world's fourth biggest energy resource after coal, oil as well as gas. Of the globe's total power intake, the biomass accounts for 14%, and even over 40% in creating nations.



Professors forecast biomass power will play an important part in the future. Nowadays, numerous countries take measures to change the energy profile, as well as provide top priority to development of biomass energy. In Europe, the biomass power uses up 15% of the complete energy consumption. It is anticipated that biomass energy will certainly take the place of 20% fossil fuel. Increasingly more biomass plants will certainly go into operation in Europe, America, Canada and also Japan in the future.
