Coal-fired power plants coupled with domestic waste can achieve carbon emission reduction while processing domestic waste at low cost

which is an important development direction of coal-fired power plants in the future. This paper introduces in detail the characteristics and treatment status of domestic waste in China

as well as the coupled power generation model of domestic waste. Moreover

it analyzes the influence of coupled power generation on pulverizing and combustion system

operation safety

coal consumption

environmental protection characteristics and carbon emissions of coal-fired units. The results show that

the direct coupling power generation is recommended when the contents of heavy metals and Cl are low and the coupling ratio is small(less than 10%). Indirect coupling power generation is recommended when the contents of heavy metals and Cl are high and the coupling ratio is large. Although the parallel coupled power generation does not have policy risks

its economy is the worst. It points out that the domestic waste coupled power generation currently has problems such as lack of corresponding standards and regulations and insufficient policy support.
