What is biomass gasification?

In short, biomass gasification modern technology utilizes biomass as raw materials, oxygen, steam or hydrogen as agent, and also turn the biomass right into flammable gas with chain reaction at heat. The flammable gas can be utilized in industrial and also farming production, such as power generation, providing heat, methanol and ethanol synthesis. Biomass gasification is a convenient means to use biomass, and capitalize on the sanitation of the biofuel.



Biomass gasification power generation

Biomass gasification power generation consists of 3 procedures. small pelletizer is to transform biomass into gas fuel. Gas purification is to eliminate the impurities like ash, coke and also tar in the gas with a filtration system. Gas power generation is to melt the gas fuel in a gas turbine or an inner combustion engine. To boost the power generation efficiency, the biomass gasification nuclear power plant is furnished with a warmth recovery boiler and also a vapor generator.



The process of biomass gasification

The raw products for biomass gasification are different, consisting of timber processing waste, agriculture deposits. Such as sawdust, branch, plant straw, rice husk, corncob, etc. The material source is bountiful and also very easy to obtain.



The gasification process is executed in the gasifiers. The response process is complicated, which differs with the type of gasifier, the response condition, the functions of raw materials, the grinding dimension. However they all have the complying with processes.



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



What is biomass gasifier?

The core tools for biomass gasification is a gasifier, where the biomass is melted and also gasified right into combustible gas. The gasifiers can be identified right into fixed bed gasifier and also fluidized bed gasifier.



Dealt with bed gasifier includes simple framework, reduced financial investment, as well as very easy procedure. It has less requirement on the dimension and also sort of the raw product, however the gas production is tiny. Dealt with bed gasifier is suitable for little gasification plant. Only up-flow type taken care of bed gasifiers appropriate for large scale plant.



Fluidized bed gasifier has high warm transmission performance as well as high gasification strength. It has high gas generation price, suitable for huge as well as middle range production. It is an efficient means to understand the cycle of biomass gasification-- gas turbine generator-- vapor turbine generator. But it calls for higher cost and also challenging feeding process.



Functions of biomass gasification power generation

Biomass gasification has actually come to be one of the most economical power generation method amongst all renewable resource technology. It's detailed cost has actually approached the degree of power generation with conventional power sources.



High adaptability

The gasified biomass can be applied in interior combustion engine, gas turbine, or integrated with warm healing boiler and heavy steam boiler. You can pick an appropriate one according to the scale of your nuclear power plant to achieve high power generation efficiency. The flexibility can fulfill the decentralized application of biomass power.




High sanitation

Biomass is a kind of renewable resource. It can decrease the emission of carbon dioxide, SO2 and also various other unsafe gas. The gasification process is carried out at low temperature, so the NOX generation is reduced.



Cost-efficient

The versatility of gasification power generation makes certain the financial advantages in little range manufacturing. The gas power generation process is simple, the devices is compact, so it needs low financial investment than other renewable resource power generation.



The history as well as present scenario of biomass gasification

The biomass gasification technology has been greater than 100 years. The initial biomass gasifier appeared in 1883. It uses wood charcoal as resources, and also the fuel gas to drive the interior flammable engine in the auto or agricultural equipment. The thriving of biomass gasification is throughout the 2nd world war, when all fuel oil is used in battle as well as the residential fuel is in brief. Some countries established car gasifiers that match with the car engine.



After the second war, owing to the expedition of oil in the middle-east area, many industrialized countries utilize oil as their major power source. The biomass gasification technology has long gone stale. After the power crisis in 1973, a growing number of nations understood the fossil fuel is non-renewable and not consistently distributed. richi pellet regains the globe's focus as a mew energy innovation.




With years of advancement, biomass gasification technology has actually made terrific progression in Europe as well as America. Nowadays, the biomass gasifiers have actually accomplished high atomicity and also advanced strategy. They are utilized for heat supply, power generation, as well as fluid gas synthesis. Sweden, Denmark, Austria, Germany, America and Canada take the leading location in biomass gasification modern technology. They have achieves large industrial operation.



The application prospect of biomass gasification

In terms of energy matching, biomass is the globe's fourth biggest power resource after coal, oil and also gas. Of the world's overall energy consumption, the biomass accounts for 14%, and also over 40% in establishing nations.



Professors predict biomass energy will play a vital part in the future. Nowadays, many countries take measures to readjust the energy profile, as well as offer top priority to growth of biomass power. In Europe, the biomass energy uses up 15% of the total power consumption. It is anticipated that biomass energy will certainly take the place of 20% fossil fuel. A growing number of biomass plants will go into procedure in Europe, America, Canada and also Japan in the future.
