What is biomass gasification?

In short, biomass gasification technology utilizes biomass as raw materials, oxygen, steam or hydrogen as agent, as well as turn the biomass into combustible gas via chain reaction at high temperature. The flammable gas can be utilized in commercial and also farming manufacturing, such as power generation, supplying warmth, methanol as well as ethanol synthesis. Biomass gasification is a convenient way to take advantage 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 into gas fuel. Gas purification is to eliminate the impurities like ash, coke and tar in the gas with a filtration system. Gas power generation is to burn the gas fuel in a gas generator or an interior burning engine. To enhance the power generation efficiency, the biomass gasification nuclear power plant is furnished with a heat recuperation central heating boiler and also a steam generator.



The process of biomass gasification

The raw products for biomass gasification are numerous, including timber handling waste, agriculture deposits. Such as sawdust, branch, crop straw, rice husk, corncob, etc. The product resource is abundant as well as simple to obtain.



The gasification procedure is accomplished in the gasifiers. The reaction procedure is complicated, which varies with the type of gasifier, the reaction problem, the functions of raw materials, the grinding size. However they all consist of the adhering to processes.



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



What is biomass gasifier?

The core equipment for biomass gasification is a gasifier, where the biomass is burned and gasified into flammable gas. agricon pellet can be classified into fixed bed gasifier and fluidized bed gasifier.




Fixed bed gasifier features straightforward structure, low financial investment, and also simple operation. It has less demand on the size and also kind of the raw material, however the gas manufacturing is tiny. Taken care of bed gasifier is suitable for little gasification plant. Just up-flow type dealt with bed gasifiers appropriate for large range plant.



Fluidized bed gasifier has high warm transmission efficiency as well as high gasification intensity. It has high gas generation rate, suitable for big as well as middle scale production. It is an efficient means to realize the cycle of biomass gasification-- gas turbine generator-- steam wind turbine generator. But it needs greater expense and challenging feeding process.



Attributes of biomass gasification power generation

Biomass gasification has become the most affordable power generation approach among all renewable resource innovation. It's extensive cost has actually approached the level of power generation with standard power sources.



High adaptability

The gasified biomass can be applied in internal combustion engine, gas generator, or integrated with warm recovery boiler and also heavy steam central heating boiler. You can choose a suitable one according to the scale of your power plant to attain high power generation effectiveness. The versatility can fulfill the decentralized utilization of biomass energy.



High sanitation

Biomass is a kind of renewable resource. It can decrease the discharge of CO2, SO2 and various other dangerous gas. water ring pelletizer is accomplished at reduced temperature level, so the NOX generation is reduced.



Inexpensive

The flexibility of gasification power generation makes certain the financial advantages in little scale manufacturing. The gas power generation process is simple, the devices is small, so it calls for low financial investment than other renewable energy power generation.




The background and present circumstance of biomass gasification

The biomass gasification modern technology has been more than 100 years. The initial biomass gasifier showed up in 1883. It makes use of timber charcoal as raw material, as well as the fuel gas to drive the internal combustible engine in the vehicle or agricultural machinery. The thriving of biomass gasification is during the 2nd world war, when all fuel oil is made use of in battle and the domestic fuel is in brief. Some nations established cars and truck gasifiers that match with the vehicle engine.



After the 2nd war, owing to the exploration of oil in the middle-east area, many industrialized nations use oil as their primary energy source. The biomass gasification innovation has actually long gone stale. After Find Out More in 1973, increasingly more nations recognized the fossil fuel is non-renewable and also not evenly dispersed. Biomass gasification gains back the globe's attention as a mew energy innovation.



With years of development, biomass gasification modern technology has made great development in Europe and America. Nowadays, the biomass gasifiers have attained high atomicity as well as progressed strategy. They are utilized for warmth supply, power generation, and also fluid fuel synthesis. Sweden, Denmark, Austria, Germany, America and Canada take the leading location in biomass gasification technology. They have attains large-scale industrial operation.



The application prospect of biomass gasification

In terms of power matching, biomass is the world's fourth largest energy source after coal, oil and gas. Of the globe's complete power consumption, the biomass make up 14%, and also over 40% in creating nations.



Professors predict biomass energy will play a vital part in the future. Nowadays, several countries take measures to change the power portfolio, and give concern to growth of biomass energy. In Europe, the biomass power takes up 15% of the complete energy consumption. It is forecasted that biomass energy will replace 20% fossil fuel. An increasing number of biomass plants will certainly enter into procedure in Europe, America, Canada as well as Japan in the future.
