Dr. Sudhir Puloria invented a biomass gasifier that converts solid biomass fuels like wood and agricultural waste into a combustible gas. There are two types - a simple natural gasifier priced at Rs. 8000 and a forced draft model priced at Rs. 15000. The gasifier provides a sustainable energy source for rural areas by utilizing agricultural waste and has benefits such as reducing firewood consumption and smoke. Challenges include adequate land and waste collection, but opportunities exist in powering atta chakkis and replacing diesel generators. The gasifier offers environmental and cost benefits over fossil fuels.
2. OVERVIEW
Biomass is basically an organic material,
which includes wood, crop residues, solid
waste, animal wastes, sewage, and waste
from food processing
Biomass gasifier benefits rural poor and
the industrial sector on regular basis and is
understood easily by every day users,
whether it is a Farm or House, Hospital or a
Clinic or a Factory
3. WHAT IS BIOMASS GASIFIER
Biomass Gasifier is a thermo-chemical
reactor where Biomass gasification takes
place which is a conversion of solid fuels
(Wood & Agricultural waste etc) into a
combustible gas mixture normally called
"Producer gas".
5. Simple Natural Gasifier
Price:Rs 8000
Pay Back Period: 100 days
Wood consumption : Very high
Smoke/Fume: Very high
Fuel used: Agro based ( Cotton, soya
husk)
6. Forced Draft
Price:Rs 15000
Pay back period: 60 days
Wood consumption: Less as compared to
simple natural gasifier
Characteristics:
more systematic
ash removal system from down
works on ac blower where primary
and secondary combustion takes
place
7. ADVANTAGES
These systems basically convert woody
biomass /agricultural wastes like rice-husk,
coconut waste etc into a combustible
gas which can be used in a number of
ways:
1. Burnt like a convenient gaseous fuel
through appropriate burners in case of
thermal applications.
2. Fed into gasoline engines (S.I. Engines) to
replace gasoline etc.
8. CHALLENGES
Availability
of land
Construction
Collection of agro waste for the
production
Viable only in the rural areas where ample
raw material is available
9. OPPORTUNITIES IDENTIFIED
In villages- this model can be substituted in
the aata chakki shops
In Naxalite area the power supply is absent.
Hence, government can subsidize the gram
panchayat to have this model as a substitute
for the generators which are expensive
It can replace fuels like:
1. Coal
2. Kerosene
3. Electricity
10. USP
Uses natural resource like solar energy-
saving energy and cost
Uses machinery parts available in the rural
market
11. PROJECT FUTURE
Future is bright as the natural resources
are depleting at a faster pace. Especially
coal and hence it can be substituted
Also, electricity demand is high and the
supply is comparatively low. Thus, this
model can help in fulfilling the difference
in demand and supply
12. Benefits to the society
Offersa sustainable option to all the rural
people because they can run the gasifier
and all the farm waste
Nowadays all the farmers burn their farm
grasses to clean it for the next use
So 1 acre of farm land waste can sustain
50 families
