This document discusses biomass gasification as a process to convert various biomass feedstocks into syngas, which can then be used for power generation, thermal applications, or conversion to biofuels. It outlines the types of biomass that can be used, including agricultural and forestry residues. The environmental benefits are highlighted such as producing power in a cleaner way than liquid fuels. Large scale implementation is proposed to provide distributed power generation for rural areas and generate local employment.
3. Biomass that can be used…
Very wide variety of feedstock can be used with simple processing in terms of
sizing and moisture reduction to less than 20%, bulk density of above 100 kgs/m 3
& free flowing nature.
Agri-residues like Cotton / Shells of Arecanut,
Rice husk (as is basis &
Soyabean / Mustard stalks, Almond, Cashewnut,
no need to briquette)
Corn Cobs Groundnut, Coconut
Waste Wood, Wood chips,
Branches & Twigs Bamboo pieces & Pine
Plywood & Saw mill
needles
wastes
Sugarcane bagasse & Wild bushes and weeds Greening of waste lands
Sugarcane trash like Prosopis Juliflora, though production of
(briquetted) Lantana, Invader Bush etc. sturdy Energy species.
5. Applications
Power Generation Thermal Applications
• Irrigation Pumping • Hot Air Generators
• Village Electrification • Dryers
• Captive Power (Industries) • Boilers
• Grid-fed Power • Thermic Fluid Heaters
• Simultaneous Charcoal and • Ovens
Power Production • Furnaces & Kilns
6. Environmental Aspects

7. Environmental Aspects (contd.)
Charcoal can be sold as fuel.
Solid Biological ash can be returned to the soil.
Waste
In case of major user equipment i.e. genset,
noise level is lower than with 100% liquid
Noise fuels.
Biomass materials contain negligible Sulphur
8. Can be a system for Village / Rural
Electrification
9. Biomass Gasification Sustainable Economic
Development of Rural India
• Wealth from Waste.
• Large-Scale Employment Generation.
• More Equitable distribution of incomes &
employment.
• Great boost to Rural Entrepreneurship.
• Positive Impact on migration to urban areas.
10. The Proposed Focus can be… …
• Gasification is being recognized as an attractive technology for
Decentralized, Distributed Generation (DDG).
• Large scale implementation of Distributed Power Generation
Systems of 500 kWe to 2 Mwe.
• Preferably connected to tail ends of the rural, 11 KV grids.
• Small Power Packs available from 10-kWe onwards for
individual Village Electrification.
11. Benefits…
• Green Fuel & electricity.
• Use the systems to also generate steam,
chilling, hot water, hot air.
• High PLFs about 80%.
• Quick and modular solutions with no
pollution.
• Generate high energy, high value
charcoal & biochar as by-product.
