Apparatus and methods suitable for recovery of heat from hot flue gases are presented comprising primary heat transfer means for exchanging heat between a hot flue gas and an intermediate fluid to create a hot intermediate fluid from an originally cold intermediate fluid; one or more oxidant-fuel burners which create the main flow of hot flue gas, and transport means for transporting the hot intermediate fluid to the heat exchanger means. The apparatus and method of the invention solve the problem of recovery of heat from dirty, toxic, or erosive flue gases.

[ What is claimed is:] [1.] A method of cooling hot flue gas from combustion process, the method comprising:a) flowing the hot flue gas through a primary heat transfer means;b) flowing an initial intermediate fluid having an initial intermediate fluid temperature through said primary heat transfer means thereby exchanging heat and cooling the hot flue gas to form a cooled flue gas and a hot intermediate fluid;c) flowing the cooled flue gas to treatment means prior to exhausting the cooled flue gas;d) flowing the hot intermediate fluid to suitable heat exchange means to transfer heat to oxygen and/or fuel, and/or a load, and create a cool intermediate fluid; ande) venting the cooled intermediate fluid to atmosphere.
