What is biomass gasification?

Briefly, biomass gasification technology utilizes biomass as raw materials, oxygen, steam or hydrogen as representative, and turn the biomass into combustible gas through chain reaction at heat. The flammable gas can be made use of in industrial and agriculture production, such as power generation, supplying warmth, methanol and ethanol synthesis. Biomass gasification is a convenient means to make use of biomass, as well as capitalize on the sanitation of the biofuel.



Biomass gasification power generation

Biomass gasification power generation includes 3 procedures. Biomass gasification is to change biomass into gas fuel. Gas filtration is to eliminate the contaminations like ash, coke and tar in the gas with a filtration system. Gas power generation is to melt the gas fuel in a gas wind turbine or an interior burning engine. To enhance the power generation efficiency, the biomass gasification power plant is furnished with a warm recovery boiler and a heavy steam turbine.



The process of biomass gasification

The raw products for biomass gasification are various, consisting of timber processing waste, farming residues. Such as sawdust, branch, crop straw, rice husk, corncob, etc. The material source is bountiful as well as very easy to get.



The gasification procedure is executed in the gasifiers. The reaction process is made complex, which varies with the kind of gasifier, the response problem, the functions of resources, the grinding size. However they all have the complying with processes.



The raw products are burned in 4 layers: oxidation layer, reduction layer, thermal decomposition layer as well as drying layer. The decrease layer is the most fundamental part that affect the quality and also yield of the gas.




What is biomass gasifier?

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



Dealt with bed gasifier features straightforward structure, reduced investment, as well as very easy procedure. It has much less need on the size and also kind of the raw product, however the gas manufacturing is small. Dealt with bed gasifier appropriates for tiny gasification plant. Just up-flow type dealt with bed gasifiers appropriate for huge scale plant.



Fluidized bed gasifier has high warm transmission efficiency and also high gasification strength. It has high gas generation price, suitable for big as well as middle range manufacturing. It is an effective way to recognize the cycle of biomass gasification-- gas wind turbine generator-- vapor wind turbine generator. But it requires higher cost and also complex feeding process.



Features of biomass gasification power generation

Biomass gasification has actually become one of the most cost-effective power generation technique amongst all renewable resource modern technology. It's extensive expense has actually come close to the degree of power generation with standard energy resources.



High flexibility

The gasified biomass can be applied in internal burning engine, gas generator, or combined with warmth recuperation central heating boiler and also steam boiler. You can select an appropriate one according to the scale of your power plant to achieve high power generation effectiveness. The versatility can meet the decentralized utilization of biomass power.



High tidiness

Biomass is a kind of renewable resource. It can minimize the exhaust of CO2, SO2 and various other hazardous gas. The gasification process is executed at reduced temperature level, so the NOX generation is low.



Affordable

The adaptability of gasification power generation makes sure the financial advantages in tiny range manufacturing. The gas power generation procedure is simple, the tools is compact, so it requires low investment than various other renewable energy power generation.




The background and existing circumstance of biomass gasification

The biomass gasification innovation has been greater than 100 years. The first biomass gasifier showed up in 1883. It utilizes wood charcoal as basic material, and the fuel gas to drive the interior flammable engine in the automobile or farming machinery. The flourishing of biomass gasification is during the second world war, when all fuel oil is made use of in war as well as the domestic fuel is in brief. these details established automobile gasifiers that match with the auto engine.



After the 2nd battle, owing to the expedition of oil in the middle-east location, most established countries make use of oil as their major power resource. The biomass gasification technology has actually long stagnated. After the energy dilemma in 1973, increasingly more nations recognized the nonrenewable fuel source is non-renewable and not consistently distributed. Biomass gasification regains the globe's focus as a mew energy innovation.



With decades of development, biomass gasification technology has made fantastic development in Europe as well as America. Nowadays, the biomass gasifiers have actually accomplished high atomicity and also advanced technique. They are made use of for heat supply, power generation, and also fluid gas synthesis. Sweden, Denmark, Austria, Germany, America and Canada take the leading place in biomass gasification technology. They have attains massive commercial procedure.



The application prospect of biomass gasification

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



Professors predict biomass power will play an integral part in the future. Nowadays, lots of countries take measures to change the energy profile, and also give priority to development of biomass power. In richi pellet mill , the biomass energy uses up 15% of the complete energy intake. It is predicted that biomass energy will replace 20% fossil fuel. An increasing number of biomass plants will certainly go into operation in Europe, America, Canada and Japan in the future.
