Gasification Technology

What is Biomass Gasification?

The biomass gasification process basically converts almost all the forms of biomass or solid fuels (such as, agricultural residues, corn-wastes, rice- husks, woods, wood-wastes, etc.) into a combustible gas mixture known as producer gas. The producer gas is comprised of carbon monoxide, hydrogen, carbon dioxide, methane and nitrogen. This process of conversion is typically used for various biomass materials, and it partially limits the combustion of such biomass during the process. The partial combustion occurs when the intake of air (oxygen) supply is controlled and its less than adequate quantity is fed into the system for the combustion of biomass.
The overall process is a combination of four distinct processes -
The moisture in the feed comes out in this zone in the form of water vapour. Drying takes place in the upper most portion of the Gasifier, through heat transferred from the high temperature combustion zone.
Pyrolysis means heating in absence of oxygen at high temperatures. The organic biomass is thus chemically decomposed and volatiles are released in gaseous form and char is produced.
Combustion is the process of burning in presence of controlled oxygen and as a result heat and energy are released.
CO2 and H2O obtained as the combustion products get reduced by carbon in the presence of high temperature to finally give CO and H2.

What is a Biomass Gasifier?

The Biomass Gasifier is basically a chemical reactor in which thermo-chemical processes mentioned above take place simultaneously. It carries out the conversion of solid biomass fuel into producer gas consisting of carbon monoxide, hydrogen, carbon dioxide, methane and nitrogen. The resulting fuel gas has a calorific value of 1000-1200 kcal/nm3, and can directly be burnt with high efficiency and good degree of control without the emission of smoke. The produced gas flame temperature can be as high as 1100oC. Each kilogram of air-dried biomass with 10% moisture content yields about 2.5 nm3 of producer gas. In energy terms, the conversion efficiency of the gasification process is in the range of 80-90%.

What are The Process Benefits?

Below mentioned are some of the advantageous features of the Manglam Biomass Gasification Systems that can be an ideal solution for your Industrial Power needs.
  • Manglam Biomass Gasifier replaces the use of expensive liquid/gaseous fuels like L.D.O./F.O./CNG/LPG/Diesel/CNG by low cost solid fuels without any changes in operations, temperature profile, temperature control and cleanliness in the plant area.
  • Typically the cost of replacing 1 ltr/kg of liquid/gaseous fuel works out to be Rs 15 to 20, depending on the application and type of fuel used for gasification.
  • The heat can be increased/reduced by just adjusting a valve.
  • Very low maintenance, no operative risk, easy to operate.
  • Zero Tar/Effluent system & highest overall efficiency.
  • Auto ash removal system.
  • Worldwide environment friendly accepted renewable technology.
  • It offers clean combustion, high thermal efficiency and a good degree of control just like conventional diesel burners.
  • No emission of smoke from the gasifier.
  • Replace fossil fuels & reduce oil import.
