Project Description

Biomass Gasifier Reactor

Coal, oil, natural gas from fossil fuels such ancient creatures,They need to go through millions of years to form and which is nonrenewable resources. Oil, coal, natural gas is not renewable energy, Reserves are limited , they will eventually be replaced by renewable energy.
Biomass is solar energy to chemical energy stored in the living body of energy. Common mainly some larger number, and the more concentrated agricultural waste, such as rice husk, straw, bagasse, corn cob, etc.
Now we have many ways to use biomass, More traditional directburning, but this method is low efficiency, resulting in significantwaste and pollution. Another common use is to create methane, butnot large-scale development.
Principles to the use of fluidized bed biomass gasification underhigh temperature conditions into a combustible gas, then Re-use the gas engine or a burner for heating, this is a new way of using biomass and is currently the most promising approach.
Biomass gasification of biomass in principle under the conditions of high temperature and oxygen to decompose and produce flammable gas that is generally known as producer gas, and its in gredients include flammable gases such as H2, CO, CH4 and not flammable gases such as CO2, N2, etc.
Iomass gasification process as part of a useful gas, and part to ashes. Ash addition to field directly, but also can be used for developmentof silicon carbide, sodium silicate and other chemical products.

Gasification:

Partial oxidation process
C6H10O5+水 – >6CO+6H2 Gas phase energetic compounds–> CO, H2, CH4 25-50% O2 needed, 800-1000 oC Air, Oxygen or Steam C6H10O5+ O2 – >5CO+ CO2 +5H2
First developed in 1792 (No Natural Gas and Fuel Oil in that period)
1816 first coal gasification company in the US
1940 Gasification were used in many countries during WWII. Developing stop at 1950 due to introduction of Natural Gas and Fuel Oil
In 1970’s Oil crisis broke out twice worldwide, which accelerated the development of Gasification again.

Gasifier Reactor

This Gasifier is atmospheric Fluidized Bed Gasifier Biomass feed into Gasifier Reactor by screw conveyor. Air inlet to gasifier reactor by root blower at bottom of gasifier bed passes the multiple air nozzle for uniform air distribution.The fuel gas exit from gasifier reactor is at 700℃ and its composition is (CO, H2, CO2, CH4, N2).Bottom Ash is discharged to the bottom of Gasifier.Fly Ash is discharged to the bottom of Cyclone.

Biomass(straw) gen-set

Biomdss generating system is a process which changes biomass waste (wood , straw, chaff, bagasses)to combustible gas, and than generating in internal-combustion engine. The combustible gas of straw are CO, H2,and a small quantity of CH4. Straw gas usually contains coke tar,water and dust, it should have a pretreatment berore entering into gas gen-set.

Ash Utilization

Ash from Biomass is non-toxic and non-hazardous.It is organic and can be used as raw material forfertilizer and soil conditioner.

SiO2 68
Al2O3 17

CaO + MgO 1

For example:
Annual Body Powder of Ceramic tiles = 200,000 Tons
Annual Silica (SiO2) Consumption = 200,000 x 0.68 = 136,000 Tons
Rice Husk Ash have Silica (SiO2) = 93%
Annual Rice Husk Consumption (1set gasifier for kiln)= 57,624 Tons ,
Annual Silica from Rice Husk Ash Generation= 57,624 x 0.2 x 0.93 = 10,718 Tons
So can consume all Rice Husk Ash without disposal.
