China plans to install 30 GW of biomass power capacity by 2020. The feed-in tariff of 3.2 cents/kwh over what is paid for fossil fuel power generation certainly helps promote new biomass plants. The facilities usually burn agricultural material such as rice husks and the stalks of cotton plants. This is a quick tour of the process and a facility. The rice husks are loaded onto a truck and weighed at a station. They could be stored on site.
If necessary, the organic material can be cut into uniform sizes by this machine.
The blue structures each house one boiler. The conveyer belt takes the biomass inside, where it is burned to heat water, generating steam and then electricity. The cooling tower cools the hot water.
Meanwhile, the central control room evaluates the power generation process and equipment.
Facilities such as these have a capacity of approximately 1.2 MW per generator, a total of 2.4 MW for two generators. Usually each generator runs 2/3 of the year, depending on the availability of fuel.
Finally, connections to the grid. The other side of the building, still in construction.
A biomass plant such as this is very small. It would be easy to conclude they make very little difference. However, one of the difficult struggles faced by China is increasing the standard of living for the rural areas. Despite the wealth in the cities, poverty prevails in the countryside. These opportunities allow the rural farmers to participate in the renewable energy economy.
