Waste heat recovery boilers recover heat by generating steam and extract heat from hot fluid, generally a gas, which is produced as a by-product of a chemical reaction and has no intrinsic value as a chemical, or which is in the form of exhaust fr. The History of Boilers. Boilers, in some form, have been around for plus years. Today’s fire-tube boiler is pretty similar to the original designs used in ships and trains. The simple round steel shells set horizontally with tube sheets welded at either end remains one of . Sulfite process recovery boilers. The article gives the impression that recovery boilers are used only in the kraft process. But aren't recovery boilers also used in the sulfite process? If so, it seems appropriate to expand the article to include the use of recovery boilers in both processes. --Andersneld , 8 January (UTC).
