What is biomass gasification?

In brief, biomass gasification technology makes use of biomass as basic materials, oxygen, steam or hydrogen as agent, and also transform the biomass into flammable gas with chemical reaction at high temperature. The flammable gas can be used in commercial as well as farming production, such as power generation, providing warm, methanol and ethanol synthesis. Biomass gasification is a hassle-free method to utilize biomass, as well as make use of the tidiness of the biofuel.



Biomass gasification power generation

Biomass gasification power generation consists of 3 processes. Biomass gasification is to transform biomass into gas fuel. Gas filtration is to remove the impurities like ash, coke and tar in the gas with a filtration system. Gas power generation is to shed the gas fuel in a gas wind turbine or an internal combustion engine. To improve the power generation effectiveness, the biomass gasification power plant is furnished with a heat recuperation boiler and a heavy steam generator.



The process of biomass gasification


The raw products for biomass gasification are different, consisting of wood handling waste, farming deposits. Such as sawdust, branch, crop straw, rice husk, corncob, etc. The material resource is abundant as well as very easy to obtain.



The gasification process is executed in the gasifiers. The response procedure is made complex, which varies with the sort of gasifier, the reaction condition, the attributes of basic materials, the grinding size. Yet they all have the following procedures.



The raw materials are burned in 4 layers: oxidation layer, decrease layer, thermal decay layer and drying layer. The decrease layer is the most vital part that affect the top quality and also yield of the gas.



What is biomass gasifier?

The core equipment for biomass gasification is a gasifier, where the biomass is melted and gasified into flammable gas. The gasifiers can be classified right into taken care of bed gasifier as well as fluidized bed gasifier.



Fixed bed gasifier includes simple framework, low investment, and easy operation. It has much less need on the size and type of the raw material, yet the gas production is tiny. Taken care of bed gasifier is suitable for little gasification plant. Just up-flow type dealt with bed gasifiers are suitable for big range plant.



Fluidized bed gasifier has high warm transmission efficiency and also high gasification intensity. It has high gas generation price, suitable for big and also middle scale manufacturing. It is an efficient method to recognize the cycle of biomass gasification-- gas turbine generator-- steam wind turbine generator. However it requires higher cost as well as complex feeding procedure.



Features of biomass gasification power generation

Biomass gasification has become the most affordable power generation method amongst all renewable resource modern technology. It's extensive cost has actually come close to the degree of power generation with conventional energy sources.



High flexibility

The gasified biomass can be applied in inner burning engine, gas turbine, or incorporated with heat recovery central heating boiler and heavy steam boiler. You can select an ideal one according to the scale of your power plant to accomplish high power generation effectiveness. The versatility can satisfy the decentralized utilization of biomass power.



High cleanliness

Biomass is a type of renewable energy. It can reduce the exhaust of carbon dioxide, SO2 and other harmful gas. The gasification process is carried out at reduced temperature level, so the NOX generation is reduced.




Affordable

The flexibility of gasification power generation guarantees the economic benefits in tiny scale manufacturing. The gas power generation process is simple, the tools is portable, so it needs reduced financial investment than various other renewable energy power generation.



The background as well as existing circumstance of biomass gasification

The biomass gasification modern technology has been greater than 100 years. The initial biomass gasifier appeared in 1883. It uses wood charcoal as raw material, and also the fuel gas to drive the inner flammable engine in the car or farming machinery. The thriving of biomass gasification is during the 2nd world war, when all gas oil is utilized in battle as well as the domestic fuel remains in brief. Some countries created vehicle gasifiers that match with the vehicle engine.



After the 2nd battle, owing to the exploration of oil in the middle-east location, the majority of developed countries utilize oil as their primary energy source. The biomass gasification modern technology has long stagnated. After the energy dilemma in 1973, increasingly more nations understood the fossil fuel is non-renewable and also not consistently distributed. diy feed pellet mill as a mew power technology.



With years of development, biomass gasification innovation has made wonderful progress in Europe as well as America. Nowadays, the biomass gasifiers have actually attained high atomicity as well as progressed technique. They are used for warmth supply, power generation, and also fluid gas synthesis. Sweden, Denmark, Austria, Germany, America and also Canada take the leading area in biomass gasification innovation. They have achieves massive industrial operation.



The application prospect of biomass gasification

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



Professors anticipate biomass power will certainly play an important part in the future. Nowadays, Richi machine take measures to readjust the power profile, and offer priority to advancement of biomass energy. In Europe, the biomass energy uses up 15% of the complete power usage. It is forecasted that biomass energy will certainly replace 20% nonrenewable fuel source. More and more biomass plants will go into operation in Europe, America, Canada as well as Japan in the future.
