Patent ID: 6922984

Claim:
A heat recovery circuit comprising: a gas-turbine exhaust gas source; a primary exhaust line in operative communication with said exhaust gas source and a heat recovery system, said primary exhaust line having a first connection point downstream the gas turbine and a second connection point upstream the heat recovery system; a by-pass exhaust line having a first end and a second end, said by-pass exhaust line connected to said primary exhaust line at said first connection point on its first end, and to said second connection point on its second end, said by-pass exhaust line being capable of receiving exhaust gas from said first connection point and conveying the exhaust gas to said second connection point; a backpressure control system operatively connected to said primary exhaust line and selectively capable of reducing the pressure within said by-pass exhaust line to less than the would be pressure within said primary exhaust line in absence of said back pressure control system and said by-pass exhaust line; and a flow control system capable of selectively directing exhaust gas flow through said by-pass exhaust line and through said primary exhaust line.
