Recovery Boiler

In the present work a procedure for optimum design of waste heat recovery boiler of a combined cycle power plant has been developed. This method enables the optimization of waste heat recovery boiler independent of the rest of the system and the design thus obtained can directly be employed in an existing plant.

Abstract: This paper presents the thermodynamic performance analysis of an existing combined cycle power plant to be retrofitted with a waste heat driven aqua lithium bromide absorption refrigerator for cooling the inlet air streams to the compressor and air-cooled steam condenser. The power plant is located in the hot and humid tropical region of Nigeria, latitude 4°45′N and longitude 7°00′E. This was achieved by performing energy and exergy analysis of the integrated system. Using the operating data of the existing combined cycle power plant, the results of the analysis showed that by cooling the inlet air streams to 15oC at the compressors, and to 29oC at the air-cooled steam condenser, the net power output, thermal and exergy efficiencies of the combined cycle plant increased by 7.7%, 8.1% and 7.5% respectively while the plant total exergy destruction rate and specific fuel consumption dropped by 10.8% and 7.0% respectively. The stack flue gas exit temperature reduced from 126oC to 84oC in the absorption refrigerator, thus reducing the environmental thermal pollution. The COP and exergy efficiency of the refrigeration cycle was 0.60 and 27.0%, respectively. Results also show that the highest rate of exergy destruction in the combined cycle power plant occurred in the combustion chamber while the highest rate of exergy destruction in the absorption refrigeration cycle occurred in the evaporator followed by the absorber.

Operation And Management

Risk factor in gas-steam combined cycle power plant (CCPP) was identified by application of safety system engineering principles and techniques. The CCPP system was divided into gas transmission subsystem, gas turbine subsystem, waste heat boiler subsystem, steam turbine subsystem and generation & transformation subsystem. The accident-proneness areas in each subsystem were studied, and various accident-causation modes were clarified. The bursting leakage accident caused by failure of steam-water pipelines was analyzed, and evaluated with Fault Tree method. The targeted countermeasures of safe operation and management were proposed.

Professional Fields

The study investigates two professional fields; the questions of vegetable production in greenhouses, the necessary steam supply and heat regulations. The actuality of this investigation is provided by the planning of a combined cycle power plant of 2400 MW in Hungary. According to the plans the steam developing by generating electricity in the power plant can be used to intensify the vegetable production. In my current study I present the experiences and results gathered as member of the research and development team led by Mr. Dr. Sinórós-Szabó.
