What is biomass gasification?

In brief, biomass gasification innovation utilizes biomass as raw materials, oxygen, heavy steam or hydrogen as agent, as well as turn the biomass right into flammable gas via chain reaction at high temperature. The combustible gas can be utilized in industrial and agriculture production, such as power generation, providing warm, methanol as well as ethanol synthesis. Biomass gasification is a convenient way to take advantage of biomass, as well as make use of the sanitation of the biofuel.



Biomass gasification power generation

Biomass gasification power generation consists of 3 processes. Biomass gasification is to change biomass right into gas fuel. Gas purification is to remove the pollutants like ash, coke and also tar in the gas with a purification system. Gas power generation is to burn the gas fuel in a gas turbine or an internal combustion engine. To improve the power generation performance, the biomass gasification power plant is outfitted with a warmth recuperation central heating boiler as well as a vapor generator.



The process of biomass gasification

The raw materials for biomass gasification are different, including timber processing waste, agriculture deposits. Such as sawdust, branch, crop straw, rice husk, corncob, and so on. The product resource is bountiful and also easy to get.



The gasification process is executed in the gasifiers. The response procedure is complicated, which differs with the kind of gasifier, the reaction condition, the functions of resources, the grinding size. Yet they all include the following procedures.



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



What is biomass gasifier?

The core devices for biomass gasification is a gasifier, where the biomass is burned as well as gasified into flammable gas. The gasifiers can be classified into repaired bed gasifier as well as fluidized bed gasifier.



Dealt with bed gasifier includes basic framework, low investment, and also easy procedure. pellet mill cooler has less requirement on the size and kind of the raw product, yet the gas production is small. Dealt with bed gasifier appropriates for tiny gasification plant. Only up-flow kind fixed bed gasifiers appropriate for big range plant.



Fluidized bed gasifier has high heat transmission efficiency and high gasification strength. It has high gas generation rate, ideal for huge and also middle scale production. It is an efficient method to understand the cycle of biomass gasification-- gas turbine generator-- steam turbine generator. However it calls for higher price and difficult feeding procedure.



Functions of biomass gasification power generation

Biomass gasification has become one of the most affordable power generation approach among all renewable resource innovation. It's comprehensive expense has actually come close to the level of power generation with conventional power sources.



High flexibility

The gasified biomass can be applied in interior combustion engine, gas turbine, or integrated with heat recovery boiler and also vapor boiler. You can select a suitable one according to the scale of your nuclear power plant to attain high power generation efficiency. The versatility can fulfill the decentralized usage of biomass power.



High tidiness

Biomass is a kind of renewable energy. It can minimize the emission of CO2, SO2 as well as various other dangerous gas. sawdust pellet maker is accomplished at reduced temperature, so the NOX generation is low.



Inexpensive

The adaptability of gasification power generation ensures the economic advantages in little scale manufacturing. The gas power generation procedure is easy, the tools is small, so it calls for low financial investment than other renewable energy power generation.




The background and present scenario of biomass gasification


The biomass gasification innovation has actually been greater than 100 years. The initial biomass gasifier showed up in 1883. It uses timber charcoal as raw material, as well as the fuel gas to drive the internal combustible engine in the vehicle or agricultural machinery. The thriving of biomass gasification is during the second world war, when all fuel oil is utilized in battle and also the domestic gas remains in short. Some nations developed auto gasifiers that match with the vehicle engine.



After the 2nd battle, owing to the exploration of oil in the middle-east area, the majority of developed countries make use of oil as their main power resource. The biomass gasification technology has actually long stagnated. After the energy dilemma in 1973, more and more nations understood the nonrenewable fuel source is non-renewable and also not consistently dispersed. Biomass gasification gains back the world's focus as a mew energy modern technology.



With decades of development, biomass gasification innovation has made excellent progress in Europe and also America. Nowadays, the biomass gasifiers have actually achieved high atomicity and also progressed technique. They are used for warmth supply, power generation, as well as liquid gas synthesis. Sweden, Denmark, Austria, Germany, America and also Canada take the leading location in biomass gasification modern technology. They have achieves large industrial procedure.



The application possibility of biomass gasification

In terms of power equivalent, biomass is the world's fourth largest power source after coal, oil and gas. Of the world's total energy intake, the biomass accounts for 14%, as well as even over 40% in developing nations.



Professors forecast biomass power will certainly play an integral part in the future. Nowadays, many nations take measures to readjust the energy portfolio, and offer concern to growth of biomass energy. In Europe, the biomass energy occupies 15% of the overall power intake. It is anticipated that biomass power will certainly fill in 20% fossil fuel. An increasing number of biomass plants will certainly go into operation in Europe, America, Canada and also Japan in the future.
