Good practice for industrial coal-fired boilers

AUTHOR: John Kessels
DATE: September 2009

A significant quantity of coal is consumed globally to provide process heat and steam for commercial and industrial processes (excluding power generation). Coal-fired industrial boilers play a key role for process and comfort heat in the industrial, residential and commercial sectors. Currently no international world’s best practice (WBP) for efficient coal-fuelled industrial and commercial boilers exists. This is due to several factors including the type of coal, efficiency and size of the boiler. This report examines the opportunities and barriers to establishing WBP for stoker-fired and pulverised-fired units between 3 MW and 20 MW. This report discusses the different designs of industrial boilers, methods to improve their efficiency and the potential benefits.
