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.

Below are diagram:

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 .

Gas purification system include Venturi Scrubber, water film dust

separator , dry filter , tar collector etc. Through one set of this complete

purification system , Dust Tar included in gas are effectively treated and

collected to completely achieve the demand of internal combustion engine .

Meanwhile, dirty Cooling water are treated through biochemical treatement

technology ,achieving to recycle exhaust water and achieving the purpose of

discharge zero pollution .

(3) Fuel gas Internal Combustion Engine and Generator (gen-set)

The project is collocated with 2unit 500kw gas gen-set. Voltage :400v ,

rated power : 500kw

(4)Waste heat (Affixation value ---it is also only for clients choice )

In this system, 3 parts waste heat can be used.

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.

Power generation system: 1000KW , occupy area:500m2. gasifier and

purification occupy about 350m2, recycle water pool take up about 150m2,

Exist and Idle construction can be used for plant so as to shorten project

construction time. Meanwhile, the upfront investment is increased . make

limited fund play biggest role.

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.

Gasifier specification:

3.4 Structure of power generation system

Adopting 2unit 500kw power generator, voltage 400v.Common house can

be used to install power generator.

3.5 Construction time

Whole set gasification power generation system adopt modularize designing.

Each parts of whole system will be finished by our processing factory. Weight

of one gasification furnace is approximately 40ton. Field basic construction is

simple. Once machine arrive, they can be installed rapidly. Whole

construction needs 3 months.

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
