Question 2 of 15. 2. The smaller the piece of coal, the more efficiently it will burn -- so it's no surprise that a lot of work has to be done to get the coal ready for the boiler. Chunks of coal are first run through a crusher and then through a pulverizer, where they are ground to a powder the consistency of flour.

Main Components of Coal Power Plant: #1. Conveyor Belt. Coals from the coal storage area are transported to the plant through a large conveyor belt. The load-carrying capacity of this belt is very high because very large quantities of coal are required every day. #2. Pulverizing Plant.

One of the objectives of the pulverizer coal in such systems is to reduce the coal particle size so that 70–80% passes through a 200 mesh (75 μm) screen (summary after Scott, 1995). Pulverizing is accomplished in several different ways, including grinding with large steel balls in a bowl mill.

In a coal fired thermal power generating station raw coal is used as the main fuel in the steam generating boiler in addition to heavy fuel oil or light diesel oil as start up fuel. Raw coal is transported on a coal conveyor belt located at the tripper floor from coal handling plant and dropped into the variable speed-controlled coal

unit amount of energy to also be reduced [3]. In today's conventional coal-fired power plants, coal is burned in the form of dust. This technology allows for the combustion of a wide range of coals in terms of quality but is less effective for coals with a high ash content. Classic coal combustion technologies in power plants have a ...

In an experimental study of cofiring, where the amount of biomass mixed with coal was in the range of 0%–16% on the basis of energy input, at a high feed rate of biomass of about 24 t/h in a large-scale (300 MW) coal-fired power plant, there was a drastic reduction of NO x emissions, about 10% ( Wang et al., 2011 ).

A wide range of biomass mixed co-firing rates can be realized by applying coal/biomass dual system (coal pulverizer/burner) to coal-fired power generation technologies. Biomass co-firing rates can be adjusted without major changes of equipment. In addition, it is possible to have biomass firing in a boiler by adding a small amount of coal ash.

Coal is the most available fuel, has a rather stable price and as a result is the most cost-effective fossil-fired technology. Nowadays, crude oil or heavy fuel oil have become quite unusual as fuels for electricity generation purposes. Sulzer provides maintenance and service for all rotating equipment to improve efficiency and reliability.
