Fluidized bed combustion, and Gasification is the main trends now in Recent power plant, in which the sulfur and nitrogen gases reduced to become 10% during combustion.

Thanks for your response Dr. Edress

Fluidized bed combustion, gasification of carbon, integrated gasification combined cycle. For more information see:

Thanks Dr. Ramos

For Existing power plants we will have to increase the efficiency of the plant. Increasing efficiency will reduce consumption of coal and thereby reduces the emissions of carbon dioxide and reducing pollution.Reduction of pollution is also a prospective research area.

Amongst the new technologies for inferior coal fluidized bed coal combustion and gasification,integrated gasification combined cycle etc.

Combustion efficiency can be increased by using oxygen enriched air. Nox can be reduced by staged combustion.

Thanks for your response Dr. Ramesh Chandra.

Dear M Krishna,

My take is the trend will shift towards carbon capture, storage and utilization technologies (CCSU), Highly Efficient Low Emissions (HELE) coal-fired or IGCC power plants. See the following reference for some details on HELE Coal fired plants https://bit.ly/2v3AMX2.

Hope this helps.
