A thermal power station is a power plant in which the prime mover is steam driven. Water when heated turns into steam which drives a steam turbine. After passing through the turbine, the steam is condensed in a condenser and recycled to where it was heated. [Rankine cycle] Coal is used as a fuel to heat water in a coal based thermal power plant.
In a coal based thermal power plant, the initial process in the power generation is "Coal Handling". So in this article i will discuss the overall processes carried out at a Coal Handling plant in a coal based thermal power generating station. The huge amount of coal is usually supplied through railways. A railway siding line is taken into ...

water or steam in the steam boiler receive heat by convection from the heating surface. When any fluid in a steam boiler is heated, its density is decreases and fluid become lighter. Then the heavier or cooler fluid will flow and replace the heated portion of the fluid. In turn the cooler portion become heated are example of convection.
Figure: Schematic diagram of a Thermal power plant. Selection of site for thermal power plant • Nearness to the load centre: The power plant should be as near as possible to the load centre to the centre of load .So that the transmission cost and losses are minimum. This factor is most important when Dc supply system is adopted.
By using the MATLAB calculation tool, a processbased computer program of the coalfired power plant has been successfully validated for thermal efficiency, steam flow rate and coal consumption rate at wide plant load range. The predictions were compared with operating data of 210MW thermal power plant at different power output levels.

Limestone preparation system in flue gas desulfurization (FGD) consists of following subsystems: 1. Limestone Handling System. Limestone will be delivered to the limestone storage shed by truck. Limestone will be delivered from the limestone unloading hopper to the limestone day silo by limestone transfer conveyor and bucket elevator. 2.
Table 2 gives the main parameters of the thermal cycle and power plant. Using this table, we observe that the net power delivered by the cycle is MW which is close to the data acquired from the power plant (∼ 590 MW).The net thermal efficiency of the cycle is %, the efficiency of the boiler is about % and the net efficiency of the power plant is %.
Gateway Generating Station, a 530megawatt combined cycle natural gasfired power station in Contra Costa County, California.. A combined cycle power plant is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical land, when used to make electricity the most common type is called a combined cycle gas turbine (CCGT) 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.

Working and Construction of Thermal Power Plant It consists of the following stages: Coal and Ash Handling Arrangement: The coal and ash handling plant generally consists of: (i) Coal storage, (ii) Coal handling plant, (iii) Ash handling plant, and (iv) Ash storage.
tons each. Conveyor systems are used to transport the coal from a nearby mine to a coal stockyard and then to the power station site. The purpose of the coal stockyard is to ensure that there is sufficient coal reserves available to keep the power station in operation should the mine experience production problems.
A thermal power plant is one kind of plant or system, which is used to produce electrical power by using thermal energy. Fig. 1 Thermal power plant. Coal is mainly used as fuel. Normally brown, bituminous, and peat coals are widely used. Water is used as secondary fuel which helps to transfer thermal energy from coal.
