ABSTRACT OF THE DISCLOSURE A method is provided for preheating combustion air being supplied to a system which includes a furnace. for heating a fluid stream. The method of preheating the eombustion air being supplied to the system com- prises circulating a portion of fluid from a fluid stream first in con-con- tact heat exchange relationship with the flue gas for heat collection, then circulating this portion of fluid in con-contact heat exchange relationship with the combustion air for heat donation thereto. The rate of circulation and temperature of the portion of fluid is controllable substantially inde- pendently of the rate of flow and of the temperature of the parent fluid stream. The furnace comprises means to heat a portion of a fluid stream and includes means to circulate, at a controllable rate and temperature, such portion of fluid from a fluid stream through an adjacent loop connected to the fluid stream for collection of heat from the flue gases and donation of heat to the combustion air. This system and method provides a vastly simpli- fied and flexible air preheating system which provides a much lower cost and physical size than previous systems of its nature, and extends to the industry a preheating system generally applicable to all sizes of combustion equip- ment.
