What is biomass gasification?

In brief, biomass gasification technology uses biomass as basic materials, oxygen, steam or hydrogen as agent, as well as transform the biomass into combustible gas via chemical reaction at heat. The flammable gas can be utilized in commercial and also agriculture manufacturing, such as power generation, providing heat, methanol as well as ethanol synthesis. Biomass gasification is a practical method to utilize biomass, and also take advantages of the cleanliness 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 remove the contaminations like ash, coke as well as 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 improve the power generation performance, the biomass gasification power plant is outfitted with a warm healing central heating boiler as well as a steam generator.




The process of biomass gasification

The raw materials for biomass gasification are various, consisting of timber processing waste, farming deposits. Such as sawdust, branch, plant straw, rice husk, corncob, and so on. The material source is abundant and easy to acquire.



The gasification process is accomplished in the gasifiers. The response process is complicated, which varies with the type of gasifier, the response condition, the features of resources, the grinding size. Yet they all contain the following procedures.



The raw materials are shed in 4 layers: oxidation layer, decrease layer, thermal disintegration layer and also drying out layer. The reduction layer is one of the most important part that influence the high quality and return of the gas.



What is biomass gasifier?

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




Fixed bed gasifier features easy structure, reduced financial investment, as well as very easy operation. It has less requirement on the dimension and kind of the raw material, yet the gas production is little. Repaired bed gasifier is suitable for small gasification plant. Only up-flow type repaired bed gasifiers are suitable for large scale plant.



Fluidized bed gasifier has high heat transmission performance and also high gasification intensity. It has high gas generation price, ideal for big and middle scale manufacturing. It is a reliable way to realize the cycle of biomass gasification-- gas turbine generator-- steam wind turbine generator. Yet it calls for higher price and difficult feeding process.



Features of biomass gasification power generation

Biomass gasification has ended up being the most affordable power generation method amongst all renewable energy technology. It's detailed price has come close to the degree of power generation with traditional power resources.



High flexibility

The gasified biomass can be used in inner burning engine, gas wind turbine, or integrated with heat recovery central heating boiler and also heavy steam central heating boiler. You can select an ideal one according to the scale of your nuclear power plant to attain high power generation performance. The versatility can meet the decentralized usage of biomass power.



High tidiness

Biomass is a type of renewable energy. It can reduce the discharge of carbon dioxide, SO2 and also various other hazardous gas. The gasification procedure is performed at low temperature, so the NOX generation is low.



Cost-effective

The adaptability of gasification power generation makes sure the financial benefits in tiny scale production. The gas power generation process is basic, the tools is small, so it requires reduced financial investment than other renewable energy power generation.



The history and existing situation of biomass gasification

The biomass gasification modern technology has actually been greater than 100 years. The very first biomass gasifier appeared in 1883. It utilizes timber charcoal as raw material, as well as the fuel gas to drive the interior flammable engine in the auto or farming machinery. The prosperous of biomass gasification is throughout the second world war, when all fuel oil is used in battle as well as the residential fuel is in brief. Some nations developed automobile gasifiers that match with the vehicle engine.



After the second battle, owing to the expedition of oil in the middle-east area, most established countries utilize oil as their main power source. The biomass gasification modern technology has long gone stale. After Richi machine in 1973, a growing number of countries understood the fossil fuel is non-renewable and also not uniformly dispersed. Biomass gasification restores the world's focus as a mew energy modern technology.



With decades of advancement, biomass gasification technology has made great progress in Europe as well as America. Nowadays, the biomass gasifiers have achieved high atomicity as well as progressed technique. They are made use of for warmth supply, power generation, and also liquid gas synthesis. Sweden, Denmark, Austria, Germany, America as well as Canada take the leading location in biomass gasification technology. They have achieves massive industrial operation.



The application possibility of biomass gasification

In regards to power matching, biomass is the globe's fourth biggest power resource after coal, oil and also gas. Of the world's complete energy usage, the biomass make up 14%, and also over 40% in creating countries.



Professors forecast biomass energy will certainly play a vital part in the future. Nowadays, animal feed pelletizer take measures to change the energy portfolio, and also offer top priority to growth of biomass power. In Europe, the biomass power takes up 15% of the overall power consumption. It is predicted that biomass energy will take the place of 20% fossil fuel. A growing number of biomass plants will certainly enter into procedure in Europe, America, Canada as well as Japan in the future.
