Abstract
A rotary regenerative heat exchange apparatus having a rotor 10 carrying a mass of heat absorbent material that is ultimately exposed to a hot and a cold fluid in order that heat absorbed from the hot fluid may in turn be transferred to the cold fluid. The rotor 10 is surrounded by a housing 18 including a sector plate 30 at the hot end of the rotor that separates the fluids. A turndown indicator 40 operatively associated with the hot end sector plate 30 is provided so that the operator may at any time determine the amount of turndown of the rotor thereby permitting adjustment of the sector plate or other sealing means to reduce to a minimum any fluid leakage between the hot and cold fluids throughout a wide range of temperature variation and thermal expansion.
