What is biomass gasification?

Briefly, biomass gasification innovation utilizes biomass as resources, oxygen, steam or hydrogen as agent, and also transform the biomass right into combustible gas through chemical reaction at high temperature. The flammable gas can be made use of in commercial and also farming manufacturing, such as power generation, supplying warmth, methanol and also ethanol synthesis. Biomass gasification is a convenient method to use biomass, and also benefit from the sanitation of the biofuel.



Biomass gasification power generation

Biomass gasification power generation includes 3 processes. Biomass gasification is to change biomass right into gas fuel. Gas purification is to get rid of the impurities like ash, coke and tar in the gas with a purification system. Gas power generation is to melt the gas fuel in a gas wind turbine or an interior burning engine. To improve the power generation performance, the biomass gasification power plant is geared up with a warm recuperation central heating boiler and a heavy steam turbine.



The procedure of biomass gasification

The raw materials for biomass gasification are numerous, consisting of wood processing waste, agriculture deposits. Such as sawdust, branch, plant straw, rice husk, corncob, etc. The material source is abundant as well as very easy to get.



The gasification process is carried out in the gasifiers. The reaction procedure is made complex, which differs with the kind of gasifier, the response condition, the attributes of resources, the grinding dimension. But they all contain the complying with procedures.



The raw materials are burned in 4 layers: oxidation layer, reduction layer, thermal decomposition layer and drying out layer. The decrease layer is the most integral part that affect the top quality as well as return of the gas.



What is biomass gasifier?

The core devices for biomass gasification is a gasifier, where the biomass is burned and gasified into flammable gas. rice husk pellet machine price can be classified right into fixed bed gasifier as well as fluidized bed gasifier.



Taken care of bed gasifier includes straightforward structure, reduced financial investment, and also simple procedure. It has less requirement on the dimension as well as type of the raw product, but the gas production is little. Taken care of bed gasifier is suitable for tiny gasification plant. Just up-flow kind taken care of bed gasifiers appropriate for large range plant.




Fluidized bed gasifier has high warmth transmission performance and high gasification intensity. It has high gas generation price, suitable for large as well as middle range production. It is an effective way to understand the cycle of biomass gasification-- gas turbine generator-- steam turbine generator. However it needs higher cost as well as complicated feeding process.



Features of biomass gasification power generation

Biomass gasification has actually become the most economical power generation method among all renewable energy technology. It's detailed cost has actually come close to the level of power generation with conventional power resources.



High versatility

The gasified biomass can be applied in interior combustion engine, gas generator, or combined with warm healing boiler and steam central heating boiler. You can select a suitable one according to the range of your power plant to achieve high power generation effectiveness. The adaptability can meet the decentralized utilization of biomass power.



High sanitation

Biomass is a kind of renewable resource. It can reduce the discharge of carbon dioxide, SO2 and other dangerous gas. The gasification process is carried out at low temperature, so the NOX generation is low.



Cost-effective

The adaptability of gasification power generation guarantees the financial advantages in tiny range manufacturing. The gas power generation procedure is easy, the equipment is compact, so it needs reduced investment than various other renewable energy power generation.




The background and also present scenario of biomass gasification

The biomass gasification technology has actually been more than 100 years. The very first biomass gasifier showed up in 1883. It utilizes wood charcoal as resources, and also the fuel gas to drive the inner combustible engine in the car or farming equipment. The flourishing of biomass gasification is throughout the second world war, when all gas oil is utilized in war and the domestic fuel is in brief. Some countries established car gasifiers that match with the auto engine.



After the 2nd war, owing to the exploration of oil in the middle-east location, the majority of industrialized countries utilize oil as their primary energy source. The biomass gasification innovation has long stagnated. After the energy dilemma in 1973, an increasing number of countries recognized the nonrenewable fuel source is non-renewable as well as not uniformly distributed. Biomass gasification restores the globe's focus as a mew energy innovation.



With years of development, biomass gasification innovation has made wonderful development in Europe and also America. Nowadays, the biomass gasifiers have actually attained high atomicity and also progressed technique. They are used for warm supply, power generation, as well as fluid fuel synthesis. Sweden, Denmark, Austria, Germany, America as well as Canada take the leading location in biomass gasification modern technology. They have attains large commercial operation.



The application prospect of biomass gasification

In regards to power equivalent, biomass is the world's 4th biggest energy source after coal, oil and also gas. Of the world's overall energy intake, the biomass represent 14%, and also over 40% in creating countries.



Professors forecast biomass energy will certainly play an important part in the future. Nowadays, lots of nations take measures to adjust the power profile, and also provide concern to advancement of biomass power. In Europe, the biomass energy occupies 15% of the overall power intake. It is anticipated that biomass power will fill in 20% nonrenewable fuel source. Increasingly more biomass plants will enter into procedure in Europe, America, Canada as well as Japan in the future.
