Abstract. This paper aims at providing some guideline to plant engineers and consultants for selecting the Appropriate type of coal mill reject handing system for …
In coal milling for power stations, a 'closed-loop' process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the re-circulation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of re-circulation loops within a mill system.

Consider the following scenario. A plant require 24 units of electrical energy and 34 units of steam for its processes. If the electricity requirement is to be met from a centralised power plant (grid power) and steam from a fuel fired steam boiler, the total fuel input needed is 100 units. Refer figure-2.1 (top)
Thermal processes, such as coal-fired power plants, gasifier boilers, gas turbines and nuclear power plants, are the main sources of electricity generation, providing more than 80% of the total power supply in China and playing dominant and irreplaceable roles for electricity consumers in the long time to come.

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.

Fly ash originated from a 20 MW thermal power plant located in northern Finland. The power plant uses a bubbling fluidised bed combustion technique. The fuels used at the plant are wood and peat. The fuel ratios (dry mass) were approximately 75% wood (50% wood chips, 10% bark, and 15% recycled wood) and 25% peat.

mented and tested is a coal grinding mill, a subsystem in thermal power plant Kostolac that is used to pulverize the coal before it gets into the furnace. This algorithm will esti-mate the health of the plates within the mill based on acoustic measurements taken on the outside of the mill while the mill is in function.
The amount of mill reject is significant in older operating plant. In India for example, it is about 0.5–1.0% of coal throughput into the boiler. In this paper, an exercise is undertaken to show how these rejects could be burnt to produce low pressure process steam, which could save the bleeding of main steam of the power plant and thereby ...
