The thermal efficiency of a steam turbine is usually higher than that of a reciprocating engine. The very high power-to-weight ratio, compared to reciprocating engines. Fewer moving parts than reciprocating engines. Steam turbines are suitable for large thermal power plants. They are made in various sizes up to 1.5 GW (2,000,000 hp) turbines ...

Pulverized coal is the most efficient way of using coal in a steam generator. The coal is ground so that about 70 % will pass through 200 mesh (0.075 mm) and 99 % will pass through 50 mesh (0.300 mm). A pulverized coal boiler can be easily adapted for other fuels like gas if required later without much difficulty.

Bunker C: Bunker fuel is the colloquial term for fuel oil used by marine vessels. Bunker fuels A, B, and C are respectively downgrading quality-classifications of fuel oil, characterized by their boiling points, carbon-chain lengths, and viscosities, all of which contribute to their value (in other words, Bunker A is more valuable than Bunker C) (see Fig. 2 for a breakdown of fuel mix …

Based on the Unit load demand pulverised coal moves from the Intermediate Bunker to the Furnace. A suction fan helps in sucking the pulverized fuel to the furnace. This system is suitable, where the boiler load varies and the mills consume huge power. But, the disadvantage is that the capital cost is high due to extra bunkers and fans.

November 13, 2016 Jagarnath Mahato. The initial process in coal based thermal power plant is coal handling.The Function of coal Handling Plant in thermal power plant is to receive, process, store, feed the coal bunkers consistently over entire life of the power plant. Coal is transported in thermal power station either by railways,roadways or ...

The train enters the power plants and dumps the coal into a underground bunker. Power plant owner needs to erect the railway tracks for the train to reach the power plant. 8. Transmission Line The power needs to be evacuated by means of high voltage transmission line to the purchaser of power such as State Electricity Board.

The minimum capacity of bunker is around 10 times of mill capacity. Feeder: Coal from the bunkers send to the feeder which provide coal to mill machine. The main reason to use feeder between bunkers and mill machine is that if we directly send coal to mill, it can damage the internal part of machine due to tones of pressure applied by the coal ...

The analysis of individual mill design and operation is complex; so, for simplicity we will consider a typical mill layout for one mill type only. As VSMs have come to represent the bulk of the power station mill fleet, the explanation of mill operations will be based on this mill type. Figure 13.2 illustrates the typical key components of a VSM.

About 80% of the ash that is generated in a thermal power plant is fly ash, with the remaining 20% being bottom ash. In the last 15‐20 years, it is a trend worldwide to use dense phase pneumatic conveying for fly ash collection and handling within a power plant For different environmental, economic and product benefits, coal ash is used by ...

Example – Heat Loss through a Wall. A major source of heat loss from a house is through walls. Calculate the rate of heat flux through a wall 3 m x 10 m in area (A = 30 m 2).The wall is 15 cm thick (L 1) and it is made of bricks with the thermal conductivity of k 1 = 1.0 W/m.K (poor thermal insulator).
