10MW Waste biomass Gasification Power plant rice husk gasifier electric generator wood chips gas plant

 Introduce of biomass gasifier:

     Biomass gasifier adopts downdraft fluidized bed technology, turn various of biomass material into combustible gas, then remove the dust, cooling, remove the tar, at last get high grade energy from low grade energy.

     This technology not only confirms the biomass gasifier gas work continuously, but also improve the heat value of the combustible gas, reduce the tar content.

The working principle of biomass gasifier:

    Biomass material get into the gasifier reactor from the top of the gasifier,then it will be dried and heat, then along with the temperature increment, its volatile matter will be separated out and pyrolysis under high temperature, after pyrolysis the gas and carbon will react with supply air in the oxidation zone, then generate the CO and steam, the heat will use for remain dry area, pyrolysis and the heat absorption reaction in the reducing zone. The gas which generated from burning will go through high temperature carbon reduction zone, reacting with carbon layer(C+CO2=2CO,C+HO2=H2+CO), become CO,H2,CH4,CmHn, etc.combustible gas. The tar under oxidation and decomposition. This technology improves the heat value of the gas and also reduces the tar.

Raw material:

  Rice husk, woodchips, sawdust, bark, shavings, crop stalks, coconut hull, olive pomace, bagasse, plastic waste , palm tree .cotton straw Requirement of the feedstock particle size is ≤2 cm, moisture content ≤20 %.

Technological process:

1.The gasifier body adopts Mechanical ash clean system, combine with the feeding system , timed feeding, timed clean the ash, continuous produce gas.

2.Dust remover is made by 2 sets of cyclone separator used in series to clean the dust in the gas.

3.Cooler adopts wind pipe stucture, gas go through the wind pipe, cooled by the cold air which sended by the fan,  remove the most moisture in this period.

4.Tar cleaner consist by 4 sets of tar remover, connect the cooling water from circulating water pump, to make sure the tar remover in the cooling water.

5.The centrifugal separator adopts the priciple of centrifugal machine, it can separate the tar and gas efficiently because of the different weight.

6.Filter adopts dry type filtering method, the filter medium usually use the corncob or the industrial gas liquid  separation mesh.

7.Roots blower is the operating power of the whole equipment, it sucks air into the gasifier as the oxidizing agent to make it react. It make all the gasify system become useful gas .

8.Splitter is used for processing the qualify and unqualify gas, and split them into two ways.
Filtering cleaner last time filter process, adopts the dry filter method.
