Clean Electrical Power Generation from Municipal Solid Waste

The mountains of municipal solid waste (MSW) produced every day by human kind is a worldwide challenge. An efficient solution for dealing with the disposal of MSW from the standpoint of environmental responsibility and economic viability is to combust it in an up-to-date waste to energy (WTE) plant at approximately 1150degC temperature to generate heat used to create steam which generates electricity, distills potable (drinking) water and hot water for industrial uses. A new plant module combusts 180 metric tons of MSW and generates a minimum of 144 MWh (megawatt hours) of electricity, as well as 912,000 liters of potable water a day. The new waste heat to energy (WHE) systems utilize the waste heat in the saturated steam exiting from the primary steam turbine and the waste heat recovered from the wet scrubbing of the furnace flue gases to generate additional electricity.
