Based on these assumptions, the requirement of run-of-mine coal as sweetener in washery rejects-based power plants is 22 per cent. Accordingly, the MoP recommended linkage for ROM coal to the extent of 22 per cent of the total fuel requirement in case of such power plants.

Score: 4.6/5 (19 votes) . The majority of coal cleaning processes use upward currents or pulses of a fluid such as water to fluidize a bed of crushed coal and impurities.The lighter coal particles rise and are removed from the top of the bed. The heavier impurities are removed from the bottom.

Based on recommendations of the State Level Si After long deliberation on whether to allow coal washery-based thermal power plants in the state, the Orissa government has permitted it with conditions.

It has received a favourable report from a consultant regarding the feasibility of a washery with 12 million tonne per annum (MTPA) installed capacity along with a power plant based on reject coal generated from the washery at its biggest thermal power station at Chandrapur. The state power generation utility has floated an enquiry for ...

A total of 100 g of coal was mixed with 300 ml of water and conditioned with diesel oil (collector) in a flotation cell for 2 min. A total of 600-ml make-up water was added and conditioned further with a predetermined quantity of pine oil (frother). The pH of the slurry was adjusted to 8 during the flotation.

The paper outlines potential uses for coal washery rejects. It considers in detail the use of fluidized-bed combustion as a means of lessening rejects disposal problems, as a method of recovering energy for drying, steam raising and electricity production and as a source of ash as a substitute for natural aggregate. Considerable technical ...

Thermal power plant - a layout. So thermal power stations are driven by steam to rotate a turbine which is coupled to rotate a generator. This rotation of generator causes to produce electricity. But in more terms we require steam to drive and hence steam is generated by burning coal. As earlier told coal is mined from various place across ...

The two major uses of water in a coal based power plant are for cooling the hot steam that is used in the turbine to generate electricity, and for ash disposal. In a cooling tower based system - which is what all TPPs now have to eventually switch to -water is used to cool the steam that circulates in the boiler-turbine-condenser loop.

Thermal Power Plants. Both West Bokaro Rejects and Jharia coal washery rejects find established use in coal based Thermal Power Plants. The reliable quality and adherence to desired specifications, makes it a product of choice for thermal power plants having new technologies such as CFBC, AFBC, HRSG and Utility Water Tube Boiler.

As a rule of thumb, for every 1% reduction in ash the r every 1% reduction in ash the yield drops by 3.5 to 4.5%. Typically for reduction of ash from 40%-34%, yield may range anywhere between 70- 80%. Need of the hour is to upgrade coal washing technology to have better recovery.
