Apparatus for removing NOx and for providing better plant efficiency in combined cycle plants |
| abstract |
In a combined cycle power plant having one or more combustion turbines and a steam turbine, a dry catalytic NOx removal module is disposed in each of the turbine exhaust stacks. A waste heat exchanger system includes an economizer coil and a pair of high pressure evaporator coils on upstream and downstream sides of the NOx removal module to generate steam for injection into the turbine combustors and for delivery to a superheater coil upstream from the upstream evaporator coil. A bypass stack across the upstream evaporator coil is damper controlled to regulate the exhaust gas temperature at the entry to the NOx removal module. A downstream low pressure evaporator coil generates steam for induction into the low pressure section of the steam turbine. Superheated steam is supplied to the high pressure section of the steam turbine. The compressor inlet guide vanes are closed to increase exhaust gas temperature as required after the upstream evaporator bypass flow reaches zero and no longer controls gas temperature. If the inlet guide vanes reach the fully closed position, reductant injection flow is shut off to terminate the NOx removal process under low exhaust gas temperature conditions. A plant afterburner is operated to add heat to the exhaust gas if gas temperature is too low. |
