After undergoing a cleansing process, coal is typically burned in order to produce electricity. The coal industry has a significantly negative environmental impact on the land, water, and air. It is responsible for producing pollution such as ash, sludge, slurry, arsenic, mercury, uranium, and other heavy metals that pollute the air and waterways.

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.

How a Coal Plant Works. Coalfired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over. Here's a real ...

production problems. Inside the power station, the coal is pulverised to a fine powder in giant grinding mills. This is because pulverised coal burns quickly, like gas. The pulverised coal is transported to the boiler furnace with air where it burns. Boilers, as high as a 35storey office block, are the rectangular blocks that give power ...

Abstract. Development of renewable energy is essential to mitigating the fossil fuel shortage and climate change issues. Here, we propose to produce a new type of energy, biocoal, via a fast pyrolysis coupled with atmospheric distillation process. The high heating values of the asprepared biocoals from the representative biomass are within ...

It stands to reason that the less coal used per unit of electricity generated, the less CO2 is produced. One way to support the reduction of the amount of CO2 produced during this process is to improve the efficiency of the steam and gas turbines currently used in the generation process. These turbines convert the heat released (from burning ...
