What is the meaning of gasification?
Gasification is a technological process that can convert any carbonaceous (carbon-based) raw material such as coal into fuel gas, also known as synthesis gas (syngas for short).
What is RDF gasification?
Abstract: Gasification is a promising technology for the conversion of mixed solid waste like refuse- derived fuel (RDF) and municipal solid waste (MSW) into a valuable gas consisting of H2, CO, CH4 and CO2.
What does biomass gasification mean?
Biomass gasification is a process of converting solid biomass fuel into a gaseous combustible gas (called producer gas) through a sequence of thermo-chemical reactions.
What is garbage gasification?
Waste gasification is a chemical process where trash is heated in a low-oxygen environment to the point that it breaks down into its constituent molecules. This reaction has two products: a combustible gas called syngas and inert slag or char.
Why biomass gasification is useful?
Biomass gasification allows the conversion of different biomass feedstocks to a more convenient gaseous fuel that can then be used in conventional equipment (e.g., boilers, engines, and turbines) or advanced equipment (e.g., fuel cells) for the generation of heat and electricity.
How are gasifiers classified?
Gasifier equipment is generally classified as upward draft, downward draft and cross draft gasifiers, based on the direction of air/oxygen flow in the equipment. It should be noted that there are types of gasifier equipment which are different from types of gasification processes.
What is gasification and how does it work?
Some gasification processes aim at refining out corrosive ash elements such as chloride and potassium, allowing clean gas production from otherwise problematic feedstock material. Gasification of fossil fuels is currently widely used on industrial scales to generate electricity.
What is the Milena gasification process?
The MILENA gasification process converts biomass into a combustible product gas with high efficiency. After cleaning, this gas can be used to generate power with gas engines, gas turbines or fuel cells.
What is the energy consumption of gasification?
By far the most energy consumption related to entrained flow gasification is not the milling of the fuel but the production of oxygen used for the gasification. In a plasma gasifier a high-voltage current is fed to a torch, creating a high-temperature arc. The inorganic residue is retrieved as a glass like substance.
What is the temperature at which gasification takes place?
This creates very high gasification temperature, as high as 1000 C. Above the gasification zone, a bed of fine and hot char is formed, and as the gas is blow forced through this bed, most complex hydrocarbons are broken down into simple components of hydrogen and carbon monoxide.
