For CO 2 capture from existing coalfired power plants, postcombustion technology is thus far considered the most viable method due to its "endofpipe" characteristic. Chemical absorption or scrubbing process is currently the technology most likely to be implemented in the near future but rather energyintensive.

Incomplete combustion occurs in a coalfired unit's furnace when insufficient oxygen (O 2) is available during fuel combustion. "Excess Air" is the amount of O 2 available for combustion. Coal requires a relatively high amount of excess air to burn completely, quickly, and in the furnace compared to other types of fuel.

A hybrid design that combines waste gasification and coalfired power generation has been proposed for improving the wastetoenergy process. In the integrated scheme, municipal solid waste is fed into the plasma gasifier and converted into syngas, which is precooled by the feedwater of the coal power plant and then conveyed directly into the coalfired boiler for combustion.

Coal and oilfired process. Coal and oilfired steam power plants have steam turbines to convert the heat energy of combustion into mechanical energy, which then operates an electric generator. All plants use the steam turbine for the drop between the high pressure and temperature of the steam and the lower pressure of condensing vapor.

Introduction. Arsenic is one of the most volatile and potentially toxic elements to be released from coalfired power plants. Arsenic is primarily volatilized as As 2 O 3 (g) during hightemperature combustion process [1], [2], more than 80% of which is partitioned into the fly ashes afterward and eventually captured by dust removal device [3].
