Producing sustainable clean energy is one of the key challenges in modern power generation systems. Coalfired power plants are one of the main sources of electrical energy due to the low cost of coal compared to other fossil fuels. However, one of the major problems of the coalfired power plant is the exhaust emission of fine particulate matter.

Stage 1 The first conversion of energy takes place in the boiler. Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat. Stage 2 The second stage is the thermodynamic process. The heat from combustion of the coal boils water in the boiler to produce steam.

Coal is the main source of electricity generation in fossil fuel based power plants. The use of coal in coalfired power plant (CFPP) causes raise in global temperature due to greenhouse gases emission responsible for global warming across the globe [1, 2]. It also has an adverse impact on the health of human being.
A simplified layout of a thermal power station is shown below. Coal: In a coal based thermal power plant, coal is transported from coal mines to the generating station. Generally, bituminous coal or brown coal is used as fuel. The coal is stored in either 'dead storage' or in 'live storage'. Dead storage is generally 40 days backup coal storage ...
Introduction. Steam cycles have been used for electric power generation from coal since the early 1900's. These first coalfired power units featured outputs in the range 110 MW and the steam generator already included an economizer, an evaporator, and a superheater (Harvey et al., 2020).According to the same reference, the first steam cycle had an efficiency of only % while those ...
