MSW Power Plant

 

Garbage power generation refers to burn the municipal solid waste by special combustion boiler, and then generate electricity by steam turbo-generator set. MSW power generation firstly need to collect all kinds of garbage, and then sort them to process. The garbage with high heat value can be burned with high temperature, and the heat energy produced during high temperature combustion is converted into high temperature steam. The steam drives steam turbine to rotate the generator for electricity. For the organics unfavorable to combustion, we can take fermentation, anaerobic treatment, and finally dry it together with desulphurization. A kind of gas named methane is produced, also called marsh gas. Then through combustion, thermal energy is converted into steam, which propel turbine to rotate and drive generator to generate electrical energy.

MSW power generation technology gradually has become mature. There are mainly two types of Garbage Combustion Boilers, one is the mechanical grate type and another is fluidized bed type of boiler.

 Mechanical Grate type and Fluidized Bed type boiler are main combustion equipment of large scale MSW combustion boiler. Mechanical Grate combustion Technology is more suitable for High Heat Value MSW, and the Low Heat Value and high moisture MSW need to be added fuel oil to assist combustion. Fluidized Bed Technology has excellent adaptability for Low Heat Value MSW, higher combusting efficiency, which could enable MSW get sufficient heating, drying and comparatively complete combustion. However, this kind of technology should pay more attention to reduce secondary pollution.
