2. Background 670 million people live in rural areas in China;
More then 70 % of rural households use solid fuel;
Most biomass wastes are burnt in the field;
Thermal efficiency of old traditional stove is only 12%;
Old traditional stove emits much pollution;
IAP causes 500,000 deaths per year in China.
Now, There are 670 million people live in rural areas in China;and More then 70 % of rural households use solid fuel;
About 15 years ago, some people just burn agricultural wastes in the field; they also keep some biomass like wood, straw for cooking in the old traditional stove, which the Thermal efficiency is only 12%;
The Old traditional stove emits much pollution;
It causes 500,000fifty thousond deaths per year in China.

13. Effect of moisture content of fuel on performance
According to the test results, the increase of MC of fuel resulted in lower emission factors of CO and PM2.5.
The effect were both statistically significant (p<0.05), although the effect became weaker at higher MC.

14. China Biomass Stove Carbon Trading Project

15. Carbon program development process
Investigation
Activity:
1）survey
2）kitchen performance test(KPT)
3）monitor indoor air pollution(IAP)
Site:
Xiaohu and Hedi village, Yu County
Yangquan City, Shanxi province China
we also do the project at Guizhou and Hubei province

16. Carbon program development process
Survey
KPT
IAP
Each household can save 2.1t coal, 15,134MJ energy and reduce 4tCO2 emissions during 8 months usage period. Thus small scale CDM project can be applied. Carbon finance can be used to subsidize residents.
Before biomass stove 99% of rural households used coal with the amount of 3.15t per year. After biomass stove, most people no long used coal, which saved fuel cost and alleviate health problem.
After biomass stove each kind of pollutions is reduced effectively with 47.1%CO, 30.07%PM2.5, almost 100%SO2.
All data above is necessary for applying CDM project and can provide data support for seeking international funds.

23. The result shows that each household can save 1
The result shows that each household can save 1.79t coal and 16,141MJ energy per year with 7.6 months usage period of biomass stove.
each household can save 1.79t coal per year with 7.6 months usage period of biomass stove.
Biomass stove can both save fuel and cost and protect environment by reducing pollution emissions. Carbon finance can provide subsidy for stoves under CDM. Thus stove price is reduced and stove dissemination can be expanded, each of those stoves cost 600 RMB (100dollar)without this project, and now it cost 200RMB (33 dollars)
This carbon finance project also keep going in Hubei and Guizhou province.
Biomass stove can both save fuel and cost and protect environment by reducing pollution emissions. Carbon finance can provide subsidy for
stoves under CDM. Thus stove price is reduced and stove dissemination can be expanded, which is beneficial to rural residents.
