Biomass GasifierOpportunities in Renewable Energy
A Biomass Gasifier converts solidfuel such as wood waste, saw dustbriquettes and agro-residues convertedinto briquettes into a gaseous fuelthrough a thermo-chemical process andthe resultant gas can be used for heat andpower generation applications. Theoverall thermal efficiency of this processis more than 75%. The combustible gasmixture, known as ` producer gas, typi-cally contains carbon monoxide (20-22%), hydrogen (12-15%), nitrogen (50-54%), carbon dioxide (9-11%) andmethane (2-3%). The producer gas hasrelatively low calorific value, rangingfrom 1000 to 1100 k Cal.Nm3 (5500 MJ/Nm3).Types of Gasifiers
1. Biomass Gasifier (down-draft): inwhich one can use woody biomass orbriquettes of loose biomass. Gas gener-ated by this gasifier is clean and suit-able for power generation as well as forthermal applications where clean gas isrequired.
2. Biomass Gasifier (Up-Draft): Inwhich one can use coal, charcoal, bri-quettes of loose biomass. Gas generatedby this gasifier is not very clean and suit-able only for thermal applications. Up-draft gasifiers are multi-fuel gasifiers.
3. Biomass Gasifier (Fluidised bed):In which one can use rice husk, wheat
straw or other loose biomass asit is.
Chanderpur Works (CPW) is per-haps the only company in the world who
is supplying all types of gasifiers. Thecompany provides complete solutions,once the prospective customer informstheir application and raw material. Itidentifies the suitable gasifier for the cus-tomer then undertakes design, supply,erection and commissioning of the gas-ifiers (complete turnkey solution).
Biomass fuels that can be used in-clude fuel wood, wood chips, agriculturestalk, coconut shells, briquettes of sev-eral residues, mustard stalk, cashew-nutshells, lantana, wheat/rice husk, coal,charcoal, etc.
Potential ApplicationsThe gasifier can be used in any ap-
plication where LPG, diesel or any otherpetro-fuel is used.
This includes petro-fuel replacementin industrial kilns, stainless steel re-roll-ing industries, lime kilns, hot air genera-tors, galvanizing industries, hot watergenerator, glass melting and annealing,aluminium die-cast, copper/brass sheetindustry, resorts/hotels/farm houses, foodprocessing, bakeries, charcoal produc-tion, etc.
Power ApplicationsGasifiers from 20 kW to 1.5 MW can
be used for power requirements for vil-lage, colonies, farmhouses, hotels andcaptive generation for industries, etc. Toproduce power with gasifiers, there aretwo routes available:

1. Dual fuel application: In this sys-tem diesel generation sets are used. Pro-ducer gas is fed to the DG set, whichreplaces up to 60%-70% of the dieselconsumption. After modification, theDG set will use up to 60%-70% gas and30%-40% diesel.
2. 100% producer gas application:In this system, spark ignition engines areused and the engine runs on 100% gas.These are similar engines used in CNGapplications.
The company also has the expertisefor converting existing diesel enginesinto gas engines.
Advantages of BiomassGasification Lowest cost per kW of energy
generated among all renewableenergy sources
Extremely clean emission Reduces wood consumption up to
50% for institutional and industrialapplications, where wood is stillbeing used for thermal applications
Environmentally sound technology Easy to operate and maintain, and Replaces fossil fuels, and Being a renewable energy product
eligible for carbon credits underCDM mechanism.
Salient FeaturesThe company is an approved manu-
facturer of gasifiers by the Ministry ofNew & Renewable Energy (MNRE),Government of India. These are alsotested and approved by the Indian Insti-tutes of Technology, New Delhi andMumbai. It now offers CE marked gas-ifiers. Features include: Gasifier designed with low specifi-
cation rate, which facilitatessmooth fuel flow and avoidsbridging
Multi-fuel capability Air pre-heating for gasification
maintains high temperatures result-ing in better quality of gas forpower applications
Insulated firebox, which maintainshigh temperatures resulting in bet-ter quality of gas and longer ser-vice life
Specially designed for rural areas,reliable and rugged system, doesnot consume diesel or any otherfossil fuel operation (for 100% pro-ducer gas application
Uses spark ignition engines (for100% producer gas application),and
Efficient cleaning and cooling train.The company manufactures Down
Draft gasifiers for thermal applicationsunder technical collaboration of TERI.It has a full fledged laboratory, and acomputerised chromatograph for check-ing gas comparison and other param-eters. Besides gasifiers, the companyalso manufactures other range of prod-ucts: cement plants up to 1000 TPD, fer-tilizer plants (SSP Plants), TSP plants,NPK Plants), mineral processing plants,sugar, chemical and paper machinery,LPG bullets, material handling equip-ment (EOT cranes, conveyors, elevatorsetc.), pressure vessels, heat exchangers,bricks making machines, lime kilns.
