What is biomass gasification?

In brief, biomass gasification technology uses biomass as basic materials, oxygen, vapor or hydrogen as agent, as well as transform the biomass right into flammable gas through chain reaction at heat. The combustible gas can be made use of in industrial and also farming production, such as power generation, supplying heat, methanol and also ethanol synthesis. Biomass gasification is a hassle-free way to make use of biomass, and also capitalize on the cleanliness of the biofuel.



Biomass gasification power generation

Biomass gasification power generation includes 3 procedures. Biomass gasification is to change biomass into gas fuel. pellet cooling machine is to get rid of the contaminations like ash, coke and tar in the gas with a purification system. Gas power generation is to shed the gas fuel in a gas turbine or an inner combustion engine. To improve the power generation efficiency, the biomass gasification power plant is furnished with a warmth recovery boiler as well as a vapor wind turbine.



The process of biomass gasification

The raw products for biomass gasification are numerous, consisting of timber handling waste, agriculture deposits. Such as sawdust, branch, plant straw, rice husk, corncob, and so on. The material source is plentiful as well as easy to obtain.



The gasification procedure is carried out in the gasifiers. pellet machine for feed is made complex, which varies with the type of gasifier, the reaction problem, the features of basic materials, the grinding dimension. But they all consist of the complying with processes.



The raw materials are shed in 4 layers: oxidation layer, decrease layer, thermal decay layer and drying out layer. The reduction layer is the most integral part that influence the high quality and also return of the gas.



What is biomass gasifier?

The core devices for biomass gasification is a gasifier, where the biomass is burned and also gasified into flammable gas. The gasifiers can be classified into fixed bed gasifier as well as fluidized bed gasifier.



Fixed bed gasifier includes basic framework, reduced investment, as well as easy procedure. It has less requirement on the size as well as type of the raw material, but the gas production is small. Repaired bed gasifier is suitable for little gasification plant. Just up-flow kind repaired bed gasifiers appropriate for big scale plant.



Fluidized bed gasifier has high warm transmission effectiveness as well as high gasification intensity. It has high gas generation rate, appropriate for big as well as middle scale manufacturing. manual animal feed pellet machine is a reliable method to realize the cycle of biomass gasification-- gas turbine generator-- vapor wind turbine generator. But it requires higher expense as well as complicated feeding process.



Functions of biomass gasification power generation


Biomass gasification has become the most cost-effective power generation approach amongst all renewable resource technology. It's detailed cost has actually approached the degree of power generation with traditional power resources.



High flexibility

The gasified biomass can be applied in inner burning engine, gas generator, or combined with warm healing central heating boiler and heavy steam boiler. You can choose a suitable one according to the scale of your power plant to achieve high power generation efficiency. The versatility can satisfy the decentralized application of biomass energy.



High tidiness

Biomass is a sort of renewable energy. It can reduce the emission of CO2, SO2 and other harmful gas. The gasification procedure is accomplished at reduced temperature, so the NOX generation is reduced.




Affordable

The flexibility of gasification power generation makes certain the financial advantages in tiny scale manufacturing. The gas power generation procedure is basic, the devices is portable, so it calls for reduced financial investment than other renewable resource power generation.



The history and existing situation of biomass gasification

The biomass gasification innovation has actually been greater than 100 years. The very first 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 agricultural equipment. The flourishing of biomass gasification is during the second world war, when all fuel oil is used in battle and also the residential fuel remains in brief. Some countries developed automobile gasifiers that match with the auto engine.



After the 2nd war, owing to the expedition of oil in the middle-east location, the majority of developed nations make use of oil as their primary energy source. The biomass gasification modern technology has actually long gone stale. After the energy dilemma in 1973, an increasing number of countries recognized the fossil fuel is non-renewable as well as not evenly dispersed. Biomass gasification gains back the globe's interest as a mew energy modern technology.



With decades of growth, biomass gasification technology has actually made great progress in Europe as well as America. Nowadays, the biomass gasifiers have actually attained high atomicity as well as progressed method. They are used for warmth supply, power generation, and also fluid gas synthesis. Sweden, Denmark, Austria, Germany, America and also Canada take the leading place in biomass gasification modern technology. They have attains large commercial operation.



The application possibility of biomass gasification

In regards to power matching, biomass is the globe's fourth largest power source after coal, oil and also gas. Of the globe's complete energy usage, the biomass make up 14%, as well as also over 40% in developing nations.



Professors predict biomass power will play an important part in the future. Nowadays, numerous countries take measures to readjust the power profile, and give concern to growth of biomass energy. In Europe, the biomass energy uses up 15% of the total power intake. It is forecasted that biomass energy will take the place of 20% nonrenewable fuel source. Increasingly more biomass plants will go into procedure in Europe, America, Canada as well as Japan in the future.
