May 15, 2016· In this study, numerical analyses of repowering of a thermal power plant boiler using plasma combustion systems were performed. In order to reduce the energy consumption of the power plant, fuel-oil burners were disassembled and plasma combustion systems were installed on the surfaces of the boiler.

However, it is just as important to reduce the amount of carbon dioxide (CO 2) that ends up in the waste flue gas that comes out of the flue stack of a power station. This is done by improving the efficiency of the coal combustion process. It stands to reason that the less coal used per unit of electricity generated, the less CO 2 is produced.

⇒⇒In this power plant, The cost of generation is lesser than that of the diesel power station. ⇒⇒ Thermal plants are able to respond to the load demand more effectively and support the performance of the electrical grid. Disadvantages of thermal power plant ⇒⇒ Thermal power plant creates pollution due to large amount of smoke and fumes because of coal combustion.

Coal ash, also referred to as coal combustion residuals or CCRs, is produced primarily from the burning of coal in coal-fired power plants. Coal ash includes a number of by-products produced from burning coal, including: Fly Ash, a very fine, powdery material composed mostly of silica made from the burning of finely ground coal in a boiler.

US coal power plants emitted more than 3.1 million tons of SO 2 in 2014. Nitrogen oxides (NOx): Nitrous oxides are visible as smog and irritate lung tissue, exacerbate asthma, and make people more susceptible to chronic respiratory diseases like pneumonia and influenza. In 2014, US coal power plants emitted more than 1.5 million tons.

2. Process description of a coal-fired power plant A coal-fired power plant burns coal to produce electricity. In a typical coal-fired plant, there are pulverisers to mill the coal to a fine powder for burning in a combustion chamber of the boiler. The heat produced from the burning of the coal generates steam at high temperature and pressure.

Steam coal, also known as thermal coal, is used in power stations to generate electricity. Coal is first milled to a fine powder, which increases the surface area and allows it to burn more quickly. In these pulverised coal combustion (PCC) systems, the powdered coal is blown into the combustion chamber of a boiler where it is burnt at high
