What is biomass gasification?

In short, biomass gasification technology uses biomass as basic materials, oxygen, vapor or hydrogen as agent, and transform the biomass into combustible gas via chain reaction at heat. The combustible gas can be used in industrial and farming production, such as power generation, providing warm, methanol and ethanol synthesis. Biomass gasification is a hassle-free method to make use of biomass, and take advantages of the cleanliness of the biofuel.




Biomass gasification power generation

Biomass gasification power generation includes 3 processes. Biomass gasification is to transform biomass into gas fuel. Gas filtration is to eliminate the contaminations like ash, coke and tar in the gas with a purification system. Gas power generation is to shed the gas fuel in a gas turbine or an internal combustion engine. To boost the power generation performance, the biomass gasification power plant is furnished with a warm recovery boiler and also a heavy steam turbine.




The process of biomass gasification

The raw products for biomass gasification are various, including timber processing waste, agriculture deposits. Such as sawdust, branch, plant straw, rice husk, corncob, and so on. small pellet mill machine is bountiful and easy to obtain.



The gasification process is executed in the gasifiers. The reaction procedure is made complex, which differs with the kind of gasifier, the response condition, the functions of raw materials, the grinding size. However they all have the adhering to processes.



The raw materials are burned in 4 layers: oxidation layer, decrease layer, thermal decomposition layer as well as drying out layer. The reduction layer is one of the most important part that influence the quality as well as yield of the gas.



What is biomass gasifier?

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



Dealt with bed gasifier includes simple framework, low investment, as well as simple procedure. It has less need on the size as well as type of the raw product, however the gas production is little. Dealt with bed gasifier appropriates for little gasification plant. Just up-flow type taken care of bed gasifiers appropriate for large range plant.



Fluidized bed gasifier has high warmth transmission effectiveness and high gasification strength. It has high gas generation rate, suitable for huge and also center scale production. It is a reliable means to understand the cycle of biomass gasification-- gas wind turbine generator-- vapor turbine generator. However it requires higher expense and also challenging feeding process.



Attributes of biomass gasification power generation

Biomass gasification has actually ended up being one of the most cost-effective power generation method among all renewable resource technology. It's comprehensive expense has actually approached the degree of power generation with standard power resources.



High flexibility

The gasified biomass can be used in interior burning engine, gas generator, or integrated with heat healing central heating boiler and also vapor central heating boiler. You can choose a suitable one according to the range of your nuclear power plant to accomplish high power generation efficiency. The adaptability can meet the decentralized application of biomass power.



High sanitation

Biomass is a sort of renewable resource. It can decrease the discharge of CO2, SO2 as well as other dangerous gas. The gasification procedure is accomplished at low temperature, so the NOX generation is low.



Cost-effective

The adaptability of gasification power generation makes sure the economic advantages in tiny range production. The gas power generation process is basic, the tools is portable, so it requires low investment than other renewable resource power generation.



The background and current situation of biomass gasification

The biomass gasification technology has been more than 100 years. The initial biomass gasifier appeared in 1883. It utilizes wood charcoal as resources, as well as the fuel gas to drive the inner flammable engine in the car or farming equipment. The flourishing of biomass gasification is during the 2nd world war, when all fuel oil is used in battle and also the domestic fuel is in brief. rice husk pellet mill established auto gasifiers that match with the car engine.



After the 2nd battle, owing to the expedition of oil in the middle-east area, many established countries use oil as their primary energy resource. The biomass gasification technology has long stagnated. After the energy dilemma in 1973, increasingly more nations understood the fossil fuel is non-renewable and not uniformly dispersed. Biomass gasification restores the world's attention as a mew power innovation.



With decades of growth, biomass gasification innovation has actually made fantastic development in Europe as well as America. Nowadays, the biomass gasifiers have actually achieved high atomicity and also progressed method. They are used for warm supply, power generation, and also liquid gas synthesis. Sweden, Denmark, Austria, Germany, America and Canada take the leading location in biomass gasification innovation. They have accomplishes massive industrial procedure.



The application possibility of biomass gasification

In regards to power equivalent, biomass is the world's 4th biggest energy resource after coal, oil and gas. Of the world's complete power consumption, the biomass accounts for 14%, and also over 40% in establishing countries.



Professors anticipate biomass power will play an important part in the future. Nowadays, many countries take measures to adjust the power portfolio, and provide priority to advancement of biomass energy. In floating fish feed pellet making machine , the biomass power occupies 15% of the complete power intake. It is anticipated that biomass power will certainly replace 20% fossil fuel. Increasingly more biomass plants will certainly go into procedure in Europe, America, Canada as well as Japan in the future.
