What is biomass gasification?
Briefly, biomass gasification technology uses biomass as resources, oxygen, heavy steam or hydrogen as agent, and transform the biomass into combustible gas with chain reaction at high temperature. The combustible gas can be utilized in industrial and agriculture production, such as power generation, supplying warmth, methanol as well as ethanol synthesis. Biomass gasification is a hassle-free way to utilize biomass, and take advantages 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 remove the pollutants 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 boost the power generation effectiveness, the biomass gasification nuclear power plant is furnished with a heat healing central heating boiler as well as a steam 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, and so on. The material source is bountiful and also easy to acquire.

The gasification process is accomplished in the gasifiers. The reaction process is complicated, which varies with the type of gasifier, the response condition, the functions of raw materials, the grinding dimension. Yet they all include the adhering to procedures.

The raw products are melted in 4 layers: oxidation layer, decrease layer, thermal disintegration layer as well as drying layer. The decrease layer is one of the most vital part that influence the quality and also yield of the gas.

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

Taken care of bed gasifier features simple framework, reduced financial investment, and simple operation. It has much less requirement on the size and sort of the raw material, yet the gas manufacturing is tiny. Taken care of bed gasifier is suitable for tiny gasification plant. Just up-flow kind dealt with bed gasifiers appropriate for big range plant.

Fluidized bed gasifier has high warmth transmission effectiveness as well as high gasification intensity. It has high gas generation rate, appropriate for huge and center range manufacturing. It is an efficient means to recognize the cycle of biomass gasification-- gas turbine generator-- heavy steam turbine generator. But it needs greater expense as well as complex feeding process.

Biomass gasification has actually ended up being one of the most affordable power generation method among all renewable energy innovation. It's extensive expense has approached the level of power generation with traditional power sources.

High adaptability
The gasified biomass can be used in interior combustion engine, gas generator, or combined with warm recovery boiler and also vapor central heating boiler. You can select an appropriate one according to the range of your nuclear power plant to attain high power generation efficiency. The adaptability can satisfy the decentralized application of biomass energy.

High tidiness
Biomass is a type of renewable resource. It can decrease the discharge of carbon dioxide, SO2 as well as various other unsafe gas. The gasification procedure is executed at low temperature level, so the NOX generation is low.

Inexpensive
The versatility of gasification power generation makes sure the economic advantages in little range production. The gas power generation process is straightforward, the tools is small, so it requires low financial investment than various other renewable resource power generation.


The history and present scenario of biomass gasification
The biomass gasification technology has been more than 100 years. The first biomass gasifier appeared in 1883. It uses wood charcoal as raw material, and also the fuel gas to drive the internal combustible engine in the car or farming equipment. The flourishing of biomass gasification is throughout the 2nd world war, when all fuel oil is used in battle as well as the domestic gas is in short. Some countries established automobile gasifiers that match with the car engine.

After the second battle, owing to the exploration of oil in the middle-east area, the majority of established nations utilize oil as their main energy resource. The biomass gasification modern technology has actually long stagnated. After the power situation in 1973, increasingly more countries recognized the nonrenewable fuel source is non-renewable and also not evenly distributed. Biomass gasification gains back the globe's interest as a mew power innovation.

With decades of development, biomass gasification modern technology has actually made wonderful progress in Europe and America. Nowadays, the biomass gasifiers have accomplished high atomicity as well as progressed strategy. They are utilized for warm supply, power generation, as well as fluid gas synthesis. Sweden, Denmark, Austria, Germany, America as well as Canada take the leading area in biomass gasification technology. They have accomplishes large commercial procedure.

The application possibility of biomass gasification
In terms of power matching, biomass is the globe's 4th biggest power source after coal, oil as well as gas. Of the globe's total energy usage, the biomass make up 14%, and also also over 40% in establishing countries.

Professors forecast biomass power will play an integral part in the future. Nowadays, several nations take measures to change the energy profile, as well as offer top priority to development of biomass power. In Europe, the biomass energy takes up 15% of the total energy intake. It is forecasted that biomass energy will replace 20% nonrenewable fuel source. Increasingly richi pellet will certainly enter into operation in Europe, America, Canada and also Japan in the future.
