waste heat from the boilers

How to Generate Steam Energy from Furnace Waste Heat

The heat of waste furnace-gases can be most economically utilized in the production of steam. Steam is used everywhere and always in metallurgical works. Even those which are run throughout by electric power, derived from gas-engines, are provided with steam-boiler plants at least as a reserve, or for use in special operations.
