What is biomass gasification?
In short, biomass gasification innovation utilizes biomass as raw materials, oxygen, steam or hydrogen as representative, and transform the biomass right into flammable gas via chemical reaction at heat. The combustible gas can be made use of in industrial as well as farming production, such as power generation, supplying heat, methanol and also ethanol synthesis. Biomass gasification is a convenient way to utilize biomass, and take advantages of the cleanliness of the biofuel.

Biomass gasification power generation
Biomass gasification power generation consists of 3 procedures. Biomass gasification is to change biomass into gas fuel. Gas purification is to get rid of the impurities like ash, coke as well as tar in the gas with a purification system. Gas power generation is to burn the gas fuel in a gas turbine or an internal combustion engine. To improve the power generation performance, the biomass gasification nuclear power plant is furnished with a warm recovery central heating boiler and also a steam generator.

The process of biomass gasification
The raw materials for biomass gasification are different, including timber processing waste, farming deposits. Such as sawdust, branch, crop straw, rice husk, corncob, and so on. The material resource is plentiful and also easy to obtain.

The gasification process is carried out in the gasifiers. The response process is complicated, which varies with the kind of gasifier, the reaction condition, the attributes of raw materials, the grinding size. Yet they all include the following procedures.

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

What is biomass gasifier?
The core devices for biomass gasification is a gasifier, where the biomass is burned as well as gasified right into flammable gas. The gasifiers can be identified right into dealt with bed gasifier and fluidized bed gasifier.

Fixed bed gasifier features basic structure, low financial investment, and also easy procedure. It has much less demand on the size and also kind of the raw product, but the gas production is small. Fixed bed gasifier is suitable for tiny gasification plant. Just up-flow type dealt with bed gasifiers appropriate for big scale plant.


Fluidized bed gasifier has high warmth transmission efficiency and high gasification intensity. It has high gas generation price, appropriate for big and middle range production. It is a reliable means to understand the cycle of biomass gasification-- gas turbine generator-- heavy steam wind turbine generator. However it calls for higher cost as well as challenging feeding process.

Features of biomass gasification power generation
Biomass gasification has ended up being one of the most cost-effective power generation approach among all renewable energy innovation. It's comprehensive expense has actually come close to the level of power generation with conventional energy sources.

High flexibility
The gasified biomass can be applied in internal combustion engine, gas turbine, or incorporated with heat recovery boiler and vapor boiler. You can pick an appropriate one according to the scale of your power plant to attain high power generation efficiency. The flexibility can meet the decentralized utilization of biomass power.

High sanitation
Biomass is a kind of renewable energy. richi pellet mill can minimize the exhaust of carbon dioxide, SO2 and other hazardous gas. The gasification process is performed at low temperature, so the NOX generation is reduced.

The flexibility of gasification power generation ensures the economic advantages in little scale manufacturing. The gas power generation process is straightforward, the tools is compact, so it calls for reduced financial investment than other renewable energy power generation.

The background as well as current scenario of biomass gasification
The biomass gasification modern technology has actually been greater than 100 years. The initial biomass gasifier showed up in 1883. It makes use of wood charcoal as basic material, and also the fuel gas to drive the internal flammable engine in the vehicle or agricultural equipment. The thriving of biomass gasification is during the second world war, when all gas oil is utilized in battle and also the residential gas remains in brief. Some nations developed auto gasifiers that match with the vehicle engine.

After the 2nd war, owing to the exploration of oil in the middle-east area, most developed countries use oil as their primary power source. The biomass gasification innovation has long stagnated. After the energy situation in 1973, increasingly more nations understood the nonrenewable fuel source is non-renewable and not uniformly distributed. Biomass gasification gains back the world's attention as a mew power technology.

With years of development, biomass gasification technology has actually made great progress in Europe and also America. Nowadays, the biomass gasifiers have achieved high atomicity and progressed strategy. They are utilized for heat supply, power generation, and also fluid fuel synthesis. Sweden, Denmark, Austria, Germany, America and also Canada take the leading place in biomass gasification innovation. They have achieves massive commercial operation.

The application possibility of biomass gasification
In terms of power equivalent, biomass is the world's fourth largest energy source after coal, oil as well as gas. Of the globe's overall energy consumption, the biomass represent 14%, and also also over 40% in establishing countries.

Professors predict biomass energy will play an integral part in the future. Nowadays, lots of nations take measures to adjust the power profile, and also provide top priority to advancement of biomass energy. In Europe, the biomass energy takes up 15% of the overall power usage. It is forecasted that biomass energy will replace 20% nonrenewable fuel source. More and more biomass plants will certainly enter into procedure in Europe, America, Canada and also Japan in the future.
