Patent ID: 8087248

Claim:
An apparatus comprising: a cement plant CP, a particulate separation and heat transfer system PSHTS comprising: a separator C adapted to remove substantially all large particles from the hot gas stream from the cement plant CP, a scrubber S adapted to bring the substantially large particle-free hot gas stream into heat exchange with a cooled high temperature heat transfer fluid stream to from a cooled gas stream and a heated high temperature heat transfer fluid stream including a portion of the dust from the gas stream, a pump P adapted to raise a pressure of the heated high temperature heat transfer fluid stream to a desired high pressure, a fan F adapted to remove substantially all of the dust from the pressurized heated high temperature heat transfer fluid stream, and a heat exchanger HE transferring heat from the substantially dust-free high temperature heat transfer fluid stream to the working fluid stream of the power plant PP to form the vaporized working fluid stream, and a power plant PP, where the cement plant CP producing a hot gas stream including large particles and dust, the PSHTS removes the large particles and the dust to produce a heated high temperature transfer fluid stream and transfer its heat to a working fluid stream of the power plant PP where a portion of its heat is converted to a usable form of energy.
