The boiler in a coal-fired power plant converts chemical energy contained within the coal into heat energy that is captured and carried away in hot, high-pressure steam (Figure 3.2). Coal-burning technology has a long history and has seen many plant configurations, but the most important type of plant in modern use is the pulverized coal-fired power plant, often abbreviated as PC plant.
Coal boilers are commonly used to heat water and create steam for energy production. Coal-fired boiler efficiency can often provide lower operating costs in comparison to other fossil fuels – almost 75% less than oil or natural gas. Coal, when properly handled and combusted, is one of the cleanest fossil fuels available today.
Coal boilers draw their combustion air from the bottom, up through the combustion grate. Lots of large clinkers on the combustion grate can hinder air passage, increase operation and maintenance costs and even force shutdowns of the boiler for cleaning out the clinkers.

Coal is burnt in the biomass fired 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.
In coal-fired power plants, the SCR system is normally located between the boiler economiser and the air preheater to provide an optimum tempera- ture of 350°C-400°C in the DeNOx reactor. Locating the SCR system after dust removal and
Coal-fired boilers Our coal-fired chain grate boilers and coal-fired fluidized bed boilers mainly produce hot water, saturated steam or superheated steam for industrial use. Coal-fired boilers have lower operating costs – nearly 50% lower than boilers using oil or natural gas.
One combustion company with experience in coal-to-gas conversions and retrofits for NOx emission control in power plant operations is Zeeco, Inc. Gathering the right information in advance of a
Solid waste ash from coal-fired boilers must also be removed. Some coal ash can be recycled for building materials. Fossil fueled power stations are major emitters of CO 2 , a greenhouse gas (GHG) which according to a consensus opinion of scientific organisations is a contributor to global warming as it has been observed over the last 100 years.

Jan 15, 2019 · A pulverized coal-fired boiler is an industrial boiler that generates thermal energy by burning pulverized coal. How does a steam boiler work? In pulverized coal fired boiler,The coal is pulverized to a fine powder, so that less than 2 % is +300 micro meter and 70 – 75 % is below 75 microns.
Coal received from the mines is stored in the coal yard adjacent to the power plant. It is then conveyed on a daily basis to the boiler and stored in a ‘Coal Silo’. ‘Coal feeders’ continuously feed the required amount of coal to the ‘Coal Pulverisers’. Coal Pulverisers grind the coal to a very fine powder to make it burn easily.
