How to Run a Coal Fired Boiler at the Best Efficiency

High Ash Coals – A challenge to Power Plants – Optimisation of combustion in high ash coal fired boilers is of special interest due to the organic and inorganic mix up and the large amount of variation in the organics. One such experience with Indian low reactive coal in a tangential fired steam generator of 670 T/hr capacity is given here.

How Does a Coal Power Plant Work? - Bright Hub Engineering

Thermal-based power plants can produce electricity from coal or other fuel sources. The coal-fired process requires three different steps to turn energy released from burning coal to generating electricity for consumption. Coal fired power plants, while producing power, require a lot of water and produce a lot of pollutants like ash and CO2.

Mapped: The world’s coal power plants in 2019

And there are now 78 countries using coal power, up from 66 in 2000. Another 16 plan to join the club, notably Egypt and the United Arab Emirates. CO2 emissions from existing plants are enough to breach the carbon budget for 1.5 or 2C. These limits would mean no new coal plants and closing 20% of the fleet early, according to one recent study.

The largest pressurised fluidised bed power plant in operation is a 360 MW unit in Japan. This plant, with a supercritical boiler, has a claimed efficiency of 42%. Although commercial fluidised bed power plants with capacities of over 400 MW are available, the units have not proved as efficient as supercritical PC power plants for coal combustion.

Pulverised coal combustion (PCC) | IEA Clean Coal Centre

The coal is ground (pulverised) to a fine powder, so that less than 2% is +300 µm and 70-75% is below 75 µm, for a bituminous coal. The pulverised coal is blown with part of the combustion air into the boiler plant through a series of burner nozzles. Secondary and tertiary air may also be added.
