ABSTRACT:
In the recovery of waste heat from flue gas containing particulate solids, CO.sub.2, SO.sub.2, SO.sub.3 and H.sub.2 O, several improvements are provided, e.g., passing hot flue gas, e.g., from a power plant, over heat exchange surface attackable by sulfuric acid, e.g., in a combustion air preheater, so as to release heat to said heat exchange surface and to partially cool said flue gas to a temperature within the range of about 350.degree. F. to above the condensation temperature of sulfuric acid; passing resultant partially cooled gas through a particulate removal zone to separate the particulate solids from the partially cooled flue gas; passing resultant solids-depleted, partially cooled flue gas to a regenerator containing heat exchange surface resistant to attack by sulfuric acid to release additional heat and to cool said flue gas to a temperature below the condensation temperature of sulfuric acid; and recovering the heat from the regenerator with air which is then passed through the air preheater to be used as combustion air for the furnace.
