Title: HEAT RECOVERY STEAM GENERATOR SYSTEM FOR GAS TURBINE COMBINED GENERATION, IN WHICH CATALYST FOR REMOVING NITROGEN OXIDE IS ARRANGED
Abstract:
The present invention relates to a heat recovery steam generator system in which a catalyst for removing nitrogen oxide is arranged and, more specifically, to a heat recovery steam generator system in which a catalyst for removing nitrogen oxide is arranged, the system being capable of: providing denitrification equipment in a narrow space without modifying the structure of a heat recovery steam generator system in a conventional combined heat and power plant using LNG as fuel since a metal foam capable of providing a high active surface area and simultaneously having excellent lightweightness, refractoriness, insulation and the like is used as a module of a selective reduction catalyst; and obtaining excellent denitrification performance while hardly affecting the performance of a gas turbine since pressure loss is minimized by reducing the amount of a catalyst relative to nitrogen oxide reduction efficiency.
