What is biomass gasification?

In short, biomass gasification technology utilizes biomass as resources, oxygen, vapor or hydrogen as representative, and turn the biomass right into flammable gas via chain reaction at heat. The combustible gas can be utilized in commercial and farming production, such as power generation, providing warmth, methanol and also ethanol synthesis. Biomass gasification is a hassle-free way to take advantage of biomass, and make the most of the cleanliness of the biofuel.



Biomass gasification power generation

Biomass gasification power generation consists of 3 procedures. Biomass gasification is to change biomass into gas fuel. Gas filtration is to get rid of the pollutants 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 inner combustion engine. To enhance the power generation performance, the biomass gasification nuclear power plant is geared up with a warm healing boiler and also a steam wind turbine.



The process of biomass gasification

The raw products for biomass gasification are various, consisting of timber processing waste, agriculture deposits. Such as sawdust, branch, crop straw, rice husk, corncob, and so on. The product source is plentiful and easy to acquire.



The gasification procedure is accomplished in the gasifiers. The reaction procedure is complicated, which varies with the sort of gasifier, the reaction problem, the functions of resources, the grinding size. Yet they all have the following processes.



The raw materials are shed in 4 layers: oxidation layer, decrease layer, thermal decay layer as well as drying out layer. The decrease layer is the most vital part that influence the top quality and also return of the gas.



What is biomass gasifier?

The core tools for biomass gasification is a gasifier, where the biomass is shed as well as gasified into combustible gas. commercial pellet mill can be classified into dealt with bed gasifier as well as fluidized bed gasifier.



Taken care of bed gasifier features simple structure, low financial investment, and also simple operation. It has much less need on the dimension and kind of the raw material, however the gas production is little. Fixed bed gasifier is suitable for little gasification plant. Only up-flow type repaired bed gasifiers are suitable for large range plant.



Fluidized bed gasifier has high warmth transmission effectiveness and also high gasification strength. chicken feed machine has high gas generation price, ideal for large as well as middle range production. It is an effective means to realize the cycle of biomass gasification-- gas wind turbine generator-- vapor turbine generator. However it needs higher price as well as difficult feeding procedure.



Features of biomass gasification power generation

Biomass gasification has actually become the most economical power generation approach amongst all renewable energy modern technology. It's thorough expense has approached the degree of power generation with conventional energy resources.



High versatility

The gasified biomass can be applied in inner combustion engine, gas generator, or combined with warm recuperation central heating boiler and steam central heating boiler. You can choose an appropriate one according to the scale of your nuclear power plant to accomplish high power generation efficiency. The versatility can fulfill the decentralized utilization of biomass energy.




High tidiness

Biomass is a type of renewable energy. It can decrease the discharge of carbon dioxide, SO2 as well as various other hazardous gas. The gasification process is accomplished at reduced temperature level, so the NOX generation is low.



Cost-efficient

The versatility of gasification power generation makes certain the financial advantages in small scale manufacturing. The gas power generation process is simple, the devices is small, so it needs reduced investment than various other renewable resource power generation.



The background as well as present circumstance of biomass gasification

The biomass gasification technology has actually been greater than 100 years. The first biomass gasifier showed up in 1883. It makes use of timber charcoal as resources, as well as the fuel gas to drive the interior combustible engine in the vehicle or agricultural machinery. The flourishing of biomass gasification is during the 2nd world war, when all gas oil is used in battle and also the residential fuel is in short. Some countries developed automobile gasifiers that match with the vehicle engine.



After the 2nd battle, owing to the expedition of oil in the middle-east area, many industrialized countries utilize oil as their main power resource. The biomass gasification technology has actually long stagnated. After the power dilemma in 1973, a growing number of nations recognized the nonrenewable fuel source is non-renewable and also not evenly distributed. Biomass gasification regains the world's interest as a mew energy modern technology.




With decades of growth, biomass gasification technology has made great progress in Europe as well as America. Nowadays, the biomass gasifiers have actually accomplished high atomicity and advanced technique. They are made use of for warmth supply, power generation, as well as fluid gas synthesis. Sweden, Denmark, Austria, Germany, America and Canada take the leading location in biomass gasification innovation. They have accomplishes large-scale commercial procedure.



The application prospect of biomass gasification

In terms of power matching, biomass is the world's fourth biggest energy resource after coal, oil as well as gas. Of the globe's overall power consumption, the biomass represent 14%, as well as even over 40% in creating nations.



Professors predict biomass power will certainly play a fundamental part in the future. Nowadays, numerous nations take measures to readjust the energy portfolio, and also offer top priority to growth of biomass energy. In Europe, the biomass power uses up 15% of the total energy consumption. It is anticipated that biomass power will fill in 20% nonrenewable fuel source. More and more biomass plants will certainly go into operation in Europe, America, Canada as well as Japan in the future.
