Abstract
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 dirt, toxic, or erosive flue gases.
