Abstract
Rotary regenerative heat exchange apparatus having a rotor carrying a mass of heat absorbent element that is alternately exposed to hot and cold fluids. Heat from the hot fluid is first transferred to the cool element, and upon rotation of the rotor is then transferred to the cool fluid flowing therethrough. The rotor and rotor housing that encloses the rotor are supported separately upon independent columns whereby there can be no transmission of force therebetween to induce sympathetic distortion of either the rotor or the rotor housing.
Claims4
A rotary regenerative heat exchange apparatus having a rotor including an upright rotor post and a concentric rotor shell spaced therefrom to provide an annular space therebetween, a mass of heat absorbent material carried in the annular space between the rotor post and the rotor shell, a housing surrounding the rotor in spaced relation thereto, spaced ducts at opposite ends of the rotor adapted to provide inlet and outlet ducts for a heating fluid and for a fluid to be heated, a support bearing supporting the rotor post for rotation of the rotor post and concentric rotor shell about its vertical axis, means for rotating the rotor about is vertical axis, as support column adapted to carry the support bearing, and a plurality of support pedestals subjacent the housing, said support pedestals for the housing being structurally independent from the support column for the rotor whereby the rotor housing will effect a compressive force upon each pedestal independent from the compressive force of the rotor upon the support column thereby precluding sympathetic movement therebetween.
