In Lees' Loss Prevention in the Process Industries (Fourth Edition), 2012. 12.8.4 Waste Heat Boilers. Process heat recovery boilers, or waste heat boilers, are widely used, particularly on ethylene and ammonia plants and on sulfuric acid and nitric acid plants.This type of boiler has developed as a cross between a conventional shell-and-tube heat exchanger and a firetube boiler.
