摘要： A waste heat recovery (WHR) system operates in a reverse mode, permitting using the WHR system to transfer heat to the exhaust gas of an internal combustion engine. In another configuration, a WHR system may operate in two modes. The first mode removes heat from exhaust gas of an engine to perform useful work. The second mode transfers heat to the exhaust gas. The benefit of this flexible system is that a WHR system is adaptable to rapidly heat exhaust gas at startup and during other conditions where the temperature of the exhaust gas is less than a predetermined operating range. Because of the ability to rapidly warm engine exhaust gas, an exhaust gas receiving system, such as an EGR or an aftertreatment system, may function to reduce the emissions of the engine more quickly. Because this system is reversible, it retains the capability of a conventional WHR system.
摘要翻译：废热回收（WHR）系统以反向模式运行，允许使用WHR系统将热量传递到内燃机的废气。在另一种配置中，WHR系统可以以两种模式操作。第一模式从发动机的废气中除去热量以进行有用的工作。第二种模式将热量传递给废气。该柔性系统的优点在于，WHR系统适用于在起动时和废气温度低于预定工作范围的其它条件下快速排放废气。由于能够快速地对发动机废气进行加热，所以排气接收系统（例如EGR或后处理系统）可以起到更快速地减少发动机排放的作用。因为这个系统是可逆的，它保留了常规WHR系统的能力。

摘要： In a combined cycle gas turbine configuration having at least two power blocks, stack emissions (particularly nitrous oxides or NOx but also carbon monoxide CO and unburned hydrocarbons, UHC) are controlled concurrently with part load power output. In one power block a combined cycle power plant has a relatively large heavy-duty industrial gas turbine fired to about 1,700° C. at the turbine inlet leading to a first heat recovery system. A second power block with a smaller gas turbine has a second heat recovery system. A controller adjusts coupling of flue gas and steam paths from the second power block to the first power block to meet load demand in compliance with applicable emissions regulations.

摘要： Method for operating a combined-cycle power plant is provided. The plant includes at least a gas turbine and at least a steam power generation system. The plant activates at least one electric generator connectable to an electric grid, wherein the gas turbine includes a compressor. The steam power generation system includes a steam turbine, a heat recovery steam generator and a bypass line. The method is such that the gas turbine de-loads to a condition, where the compressor operates at its nominal speed. The method is such that the steam turbine de-loads in coordination with the de-load of the gas turbine, to a condition where the total load exported by the plant to the grid is substantially equal to zero, being both the gas turbine and the steam power generation system connected.
