This is affected by coal quality, boiler cleanliness and equipment deterioration as well as by the even distribution of the pulverised fuel to the burners. Expert systems for assessing coal quality and its implications for power generation have been and continue to be

Controlling the Furnace Process in Coal-Fired Boilers

2014-4-27  We give an outline of methods using which the furnace process in coal-fired boilers can be controlled to expand the range of loads, reduce the extent to which the furnace is contaminated with slag and the amount of harmful substances is emitted, and when a change is made to another kind of fuel.

Boiler Efficiency an overview ScienceDirect Topics

P. GoldsWorthy, E. On, in The Coal Handbook: Towards Cleaner Production: Coal Utilisation, 2013. Boiler efficiency and carbon burnout. Boiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler.

Gravimetric and Volumetric Coal Feed Systems for Boilers

The gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal in response to a boiler fuel demand. This ability to accurately weigh the coal provides significant improvement over volumetric types in terms of matching the fuel delivered by the feeder to the actual process energy required on coal fired units.
