Proposal of 1000KW Gasification Power Generation with
Fluidized bed Gasifier
1 Project summaryIn order to save energy, reduce pollution, extensive use local rich biomass
resources, Hefei DeBo Biological Energy Technology CO., Ltd. has developed
fluidized bed gasification power generation technology, converting biomass to
green electricity. Power plant will not discharge pollution due to adopt biomass
as fuel materials. Biomass resource could achieve high efficiency utilization.
In order to best using Rice Husk etc., we intent to collocate one set of
1000KW fluidized bed gasifier , 1set purification system,2set 500kw fuel gas
gen-setfor this project . Gasifier gasified biomass into fuel gas, which will be
piped into purification system for removing dust, tar and other impurity.
Finally ,fuel gas genset generate electricity. Additionally, Waste Heat is
available to supply steam ,hot water and heat for drying (it is for customers
choice )
2 Technology RouteThe Technology Route adopts combination of fluidized bed gasification and
internal combustion engine to make best utilization of mentioned biomass.

1Biomass gasification Reaction (Rice Husk )
Rice Husk access to fluidized bed gasifier through Feeder located on the
bottom of gasifier. Under high-temperature , recycling and heating materials,
Biomass in gasifier meet hot air heated by air preheater entering from bottom
so that Pyrolysis& gasification reaction occurred. Hence, biomass is converted
into Biomass gas . the composition of fuel gas are mainly COH2CH4 etc.
Calorific value: 1200kcal/ m3 approximately. Moreover , including a little tar .

a. Cooling water of internal combustion genset, the temperature is about 80 ;
b. The temperature of fuel gas from gasifier is about 750C
c. Exhaust gas from internal combustion genset , the temperature is about
550 . some time 80 cooling water of power generator will be piped into
waste heat boiler and make a use of fuel gas and exhaust gas to heat the
water so as to produce steam.

3.2 Raw materials collectionstorage and preparation.Biomass Gasifier can adopt various crops biomass with moisture content
10%-20%. Fluidized bed gasification furnace is widely adaptable to materials.
Cotton stalk, straw, wheat stalk, corncob and saw dust, wood residue , tree
skin etc are all available. More materials are better to collect for power plant
running based on the practical situation of around village .
3.3 Gasification system structure
The gasification system include : 1feeder 2 fluidized bedgasifier 3cyclone separator 4air preheater 5) air blower 6Waterfilm dust catcher 7)venturi scrubber 8) dry-wet filter 9ash dischargedevice 10) Electrical control cabinet 10) steel frame
Biomass access to gasifier through feeder located on the bottom of
gasifier. Preheat air access to gasifier through air board located on the bottom
of gasifer.acheve fuel materials flow and gasified. Fuel gas after purification
will access to generator. Ash discharge device are fixed on the bottom of
cyclone separator to collect ash, which can be fertilizer after cooling.

Biomass power generation technology is highly reliable, low investing cost .
given from technology and economy, this power generation system achieve
worldwide lead level.
Except supply electricity, some potential benefits can be got, too.
1)ash in ash device can be sold to farm for fertilizer
2) reduce discharge CO2 and poison air .
3) the waste heat make use of heat boiler to produce abundant steam and hot
water for industrial using and residents.4)vinegar distilled from rice husk fuel gas can be instead of Chemical
pesticides
5Environment analysis5.1 save energy & emission reduction
Organic waste(rice husk) belongs to renewable clean energy.
Environment protection and clean biomass energy is sole renewable energy
that can be converted to clean fuel materials. Hazardous Substances from
biomass(S&Ash ) content is 90% less than bituminous coal. The emission and
absorption of Carbon compose carbon circulation in nature, achieving CO2
Zero emission. Practice has proved that biomass energy play a notable role in
reducing CO2 emission.
Because biomass is renewable energy and low(temperature
approximately 700-900 ) during gasification and little output of NOx ,
biomass power generation technology is one high degree clean energy
technology , one scientific choice of reducing CO2
emission and avoid global
environment degradation.
5.2 wastes emission detail
In this project, water used for fuel gas purification is circulation water ,
being able to recycle and reused through biochemical treatment. No exhaust
water is discharged .
Tar collected by purification system can be sold as chemical materials and
can be mixed with coal to improve calorific value of coal.
Ash through gasification furnace is one excellent potash fertilizer ,being

used to produce compound fertilizer. Due to low output of Ash, we will not
establish professional ash location in this project. But ash warehouse will be
set up . all ash will be completely consider to sell or comprehensive using.
5.3 noise control
Generally ,noise pollution are tried to control from noise resource and
transmission route. Firstly , we control from noise resource. As for
non-control noise , we adopt to block noise, reduce noise ,reduce vibration and
other control measures.
The noise of power plant is broad bound source, mainly from internal
combustion engine and pumps. as boiler discharge gas , the noise is sudden
noise, high noise, terrible affect environment . hence, mufflers will be fixed in
boiler air emission pipe and safe valve air emission pipe. Blocked noise work
room and main control room will adopt to block noise. Moreover, power plant
will be designed reasonable layout, paying attention to effection of isolating
and reducing noise. Outside of plant, green belt need be set out to further
reuduce the influence of noise
After adopting all measures, the influence of noise will achieve
