    摘要： Heat is recovered from the flue gas stream discharged from a power plant combustion zone by heat exchange of the flue gas stream against the air stream which enters the combustion zone. Each gas stream flows through two rotating air preheaters, with a first preheater rotating at a constant rate and a second preheater rotating at a variable rate. The rate of rotation of the second preheater is varied to adjust the temperature of either the heated air stream or the temperature of the flue gas stream after passage through the preheaters.

    摘要： A system for recovering the waste heat normally exhausted into the atmosphere by chemical or other processing plants. The invented system comprises a heat exchange apparatus located in the exhaust stack or flue passage, heat transfer means for carrying the waste heat absorbed from the exhaust gases to a location remote therefrom, and a second heat exchange apparatus for releasing the transferred waste heat for beneficial use at said remote location. The present invention also includes temperature and pressure control means which enhance the safety and efficiency of the system's operation. The heat transfer means disclosed in this invention is a high temperature liquid (and associated pumping and piping means) capable of withstanding temperature up to 900 F. without flashing, changing state, or corroding the heat exchange apparatuses.
