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".

4. INVENTION OF DR.SUDHIR
PULORIA
 Product:Biomass Gasifier
 Range: Rs.3000 – Rs.15000
 Types:
 Simple natural gasifier
 Forced draft

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
