A combinedcycle power plant uses both a gas and a steam turbine together to produce up to 50% more electricity from the same fuel than a traditional simplecycle plant. The waste heat from the gas turbine is routed to the nearby steam turbine, which generates extra power. Tour a combined cycle power plant.
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.

Model validation was done but only over a small load range, from full to 88% load, by comparing only a few key process variables, namely coal flow, steam flow, and plant efficiency. Chen et al. [9] and Chen and Bollas [13] used the Dymola simulation environment and Thermal Power Library to build a dynamic model of a subcritical plant.
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.
Like any thermal power station, we generate electricity from steam. Our entire process can be simplified into four main steps: Fuel is burned to create heat. By using finely pulverized coal, efficient combustion is assured and high temperatures are achieved. The heat is applied to demineralized water inside the boiler, turning it into steam.
