What is biomass gasification?

In brief, biomass gasification modern technology uses biomass as raw materials, oxygen, vapor or hydrogen as representative, and also transform the biomass right into combustible gas via chain reaction at heat. The combustible gas can be utilized in industrial as well as agriculture manufacturing, such as power generation, supplying warmth, methanol as well as ethanol synthesis. Biomass gasification is a hassle-free means to utilize biomass, and also make the most of the cleanliness of the biofuel.



Biomass gasification power generation

Biomass gasification power generation includes 3 procedures. Biomass gasification is to transform biomass into gas fuel. Gas filtration is to remove the pollutants like ash, coke and also tar in the gas with a purification system. Gas power generation is to shed the gas fuel in a gas generator or an internal combustion engine. To boost the power generation performance, the biomass gasification nuclear power plant is geared up with a warmth recovery boiler and also a vapor generator.



The procedure of biomass gasification

The raw products for biomass gasification are various, including wood processing waste, farming deposits. Such as sawdust, branch, crop straw, rice husk, corncob, and so on. The product resource is bountiful and also very easy to get.



The gasification procedure is executed in the gasifiers. Richi machinery is complicated, which differs with the type of gasifier, the reaction condition, the attributes of basic materials, the grinding size. Yet they all consist of the complying with processes.



The raw products are melted in 4 layers: oxidation layer, reduction layer, thermal decay layer and also drying layer. The reduction layer is the most integral part that affect the top quality and also return of the gas.



What is biomass gasifier?

The core devices for biomass gasification is a gasifier, where the biomass is shed and also gasified into combustible gas. The gasifiers can be classified right into taken care of bed gasifier and also fluidized bed gasifier.



Fixed bed gasifier includes easy structure, low investment, and also very easy procedure. It has less need on the size as well as type of the raw product, yet the gas manufacturing is little. Fixed bed gasifier is suitable for tiny gasification plant. Just up-flow type repaired bed gasifiers appropriate for large range plant.



Fluidized bed gasifier has high warmth transmission efficiency as well as high gasification intensity. It has high gas generation rate, appropriate for big and also middle scale production. It is an efficient means to realize the cycle of biomass gasification-- gas turbine generator-- steam wind turbine generator. However it calls for higher price and also complex feeding procedure.



Attributes of biomass gasification power generation

Biomass gasification has actually come to be the most cost-effective power generation method among all renewable resource modern technology. It's thorough price has actually come close to the degree of power generation with traditional energy sources.



High versatility

The gasified biomass can be applied in inner combustion engine, gas generator, or integrated with warm recuperation central heating boiler and steam boiler. You can choose a suitable one according to the range of your nuclear power plant to accomplish high power generation performance. The versatility can fulfill the decentralized application of biomass energy.




High cleanliness

Biomass is a sort of renewable resource. It can minimize the emission of CO2, SO2 and also various other unsafe gas. The gasification procedure is carried out at low temperature, so the NOX generation is reduced.



Cost-efficient

The versatility of gasification power generation ensures the financial advantages in little range production. The gas power generation process is easy, the devices is portable, so it requires reduced financial investment than other renewable resource power generation.



The history as well as existing circumstance of biomass gasification

The biomass gasification modern technology has actually been greater than 100 years. The very first biomass gasifier showed up in 1883. It utilizes timber charcoal as basic material, and the fuel gas to drive the internal combustible engine in the vehicle or agricultural machinery. The thriving of biomass gasification is throughout the 2nd world war, when all gas oil is made use of in battle and the residential gas remains in brief. Some nations developed automobile gasifiers that match with the automobile engine.




After the 2nd war, owing to the exploration of oil in the middle-east area, a lot of established nations make use of oil as their major power source. The biomass gasification technology has long gone stale. After the energy dilemma in 1973, more and more nations recognized the nonrenewable fuel source is non-renewable and also not consistently distributed. Biomass gasification restores the world's interest as a mew power modern technology.



With years of development, biomass gasification modern technology has actually made fantastic development in Europe and also America. Nowadays, the biomass gasifiers have actually achieved high atomicity and also advanced technique. They are made use of for heat supply, power generation, and also liquid gas synthesis. Sweden, Denmark, Austria, Germany, America and also Canada take the leading area in biomass gasification innovation. They have achieves massive commercial operation.



The application possibility of biomass gasification

In regards to energy equivalent, biomass is the globe's 4th largest power resource after coal, oil as well as gas. Of the globe's complete power consumption, the biomass accounts for 14%, and also over 40% in developing nations.



Professors anticipate biomass power will play an important part in the future. Nowadays, several countries take measures to change the energy portfolio, as well as offer top priority to growth of biomass power. In Europe, the biomass energy occupies 15% of the overall power usage. It is forecasted that biomass energy will take the place of 20% fossil fuel. More and more biomass plants will enter into operation in Europe, America, Canada and Japan in the future.
