The essence of NovelEdge™ Technology is the ability to utilize a great deal of supplemental firing to add low cost capacity, only without the detrimental effects on heat rate that is prevalent in the conventional combined cycle. To accomplish this task, a unique heat recovery method, in conjunction with a more efficient bottoming cycle is employed.

The process schematic below illustrates a high-efficiency conventional combined cycle plant that is typical in the industry. This cycle utilizes a gas turbine, 3 pressure level HRSG, and a reheat steam turbine. Design point HRSG stack temperatures are normally in the 180 to 220 F range. The steam turbine typically provides 30 to 50% of the overall plant capacity (a steam turbine to gas turbine capacity ratio of 0.43 to 1.0).



The NovelEdge™ Technology process schematic is similar to the conventional combined cycle plant in that it utilizes a gas turbine, an HRSG, and a reheat steam turbine. In addition, design point HRSG stack temperatures are normally in the 180 to 220 F range. However, the NovelEdge™ Technology HRSG has only one high-pressure drum, versus 3 pressure levels in the conventional plant. The steam turbine is much larger and does not require admissions for IP and LP steam. And the amount of supplemental firing is not as limited as in the conventional plant, as there is no worry concerning boil-out in the IP section. For the NovelEdge™ Technology process, the steam turbine typically provides 50 to 70% of the overall plant capacity (a steam turbine to gas turbine capacity ratio of 1.0 to 2.3).
