摘要
In Mongolia,approx.200,000 herder families are breeding the livestock for their livings.Nearly half of them are not able to use the energy in proper or sustainable manner yet.Both the herd population and number of domestic animals reach 70.0 million in Mongolia.It is assumed that the power demand for a typical herder family is around 10 to 20 kWh/day.In addition,there is a demand of heat for the herder families,especially in winter season.The herder family moves around for the fresh grass for their livestock.Therefore,they need to have a portable power supply source.There is an abundant biomass resource in their living circumstances.The 2.0 kW portable biomass micro-cogeneration systems were designed to supply electricity and heat to herder family.The residue of the biomass in the steppe emits greenhouse gas(GHG)indeed.It is necessary to use biomass as an energy source,especially for electricity to reduce emitting of the GHG.
