Biomass Gasification Process

Biomass that can be used…

Rice husk (as is basis & no need to briquette)

Agri-residues like Cotton / Soyabean / Mustard stalks,

Corn Cobs

Shells of Arecanut, Almond, Cashewnut, Groundnut, Coconut

Waste Wood, Wood chips, Plywood & Saw mill

wastes

Branches & Twigs Bamboo pieces & Pine needles

Sugarcane bagasse & Sugarcane trash

(briquetted)

Wild bushes and weeds like Prosopis Juliflora,

Lantana, Invader Bush etc.

Greening of waste lands though production of

sturdy Energy species.

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/m3 & free flowing nature.

Charcoal can be sold as fuel.Biological ash can be returned to the soil.

In case of major user equipment i.e. genset, noise level is lower than with 100% liquid fuels.Nois

Biomass materials contain negligible Sulphur

Can be a system for Village / Rural Electrification

• 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.

Biomass Gasification Sustainable Economic Development of Rural India

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.

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.
