Thermal performance optimization and burner system optimization of HRSG boiler in F-class gas turbine combined cycle power generation system

1. Thermal performance optimization of HRSG boiler
HRSG Boiler plays an important role in converting the heat in the high-temperature exhaust gas discharged by the gas turbine into steam in the F-class gas turbine combined cycle power generation system. Optimizing its thermal performance can not only improve the quality and quantity of steam, but also improve the efficiency of the entire combined cycle system.

Steam parameter optimization
Improving the parameters of main steam and reheat steam is an effective way to improve the thermal performance of HRSG Boiler. By increasing the pressure and temperature of steam, the work capacity of steam can be improved, thereby increasing the power generation output of the combined cycle unit. However, this also increases the initial investment and operation and maintenance costs of the equipment accordingly. Therefore, it is necessary to reasonably select steam parameters while ensuring economy. For example, detailed thermal calculation and simulation of HRSG boilers are performed to determine the optimal combination of steam parameters.

Heating surface layout optimization
The layout of the heating surface has an important influence on the thermal performance of F Class Gas Turbines HRSG Boiler. By optimizing the type and layout of the heating surface, the heat transfer efficiency can be improved and the heat loss can be reduced. For example, the use of high-efficiency heat transfer elements such as spiral finned tubes can increase the heat transfer area and improve the heat transfer coefficient. At the same time, reasonable layout of the heating surface can also avoid problems such as local overheating and corrosion, and extend the service life of the equipment.

Optimization of the steam-water system
The optimization of the steam-water system is also the key to improving the thermal performance of HRSG Boiler. By optimizing parameters such as the circulation ratio and feed water temperature, the stable operation of the steam-water system can be ensured, and the quality and quantity of steam can be improved. In addition, the use of advanced steam-water separation technology and sewage discharge system can reduce impurities and salts in the steam-water system and improve the purity and thermal efficiency of steam.

Control system optimization
The advanced control system can monitor and adjust the operating status of the HRSG boiler in real time to ensure its stable operation under the best working conditions. By optimizing the control strategy, precise control of parameters such as steam temperature and pressure can be achieved, and the thermal performance and operating efficiency of the HRSG boiler can be improved.

2. Burner system optimization
The burner system is a key component of the F-class gas turbine combined cycle power generation system. The optimization of its performance is of great significance to improving the efficiency of the gas turbine and the thermal performance of the HRSG Boiler.

Burner type selection
Different types of burners have different combustion characteristics and efficiencies. When selecting a burner, it is necessary to select a suitable burner type according to the model and operating requirements of the gas turbine. For example, the DLN series burner is famous for its low NOx emissions and high combustion efficiency, and is one of the commonly used burner types for F-class gas turbines.

Burner structure optimization
The structure of the burner has an important influence on its combustion efficiency and emission performance. By optimizing the structure of the burner, such as increasing the length of the premixing section and adjusting the nozzle angle, the mixing and combustion process of the fuel can be improved, the combustion efficiency can be improved, and emissions can be reduced.

Fuel adaptability optimization
With the adjustment of the energy structure and the development of renewable energy, the types of fuels for gas turbines are also changing. In order to improve the adaptability of the burner to different fuels, the fuel adaptability of the burner needs to be optimized. For example, by adjusting the fuel supply system and control system of the burner, stable combustion and efficient utilization of different fuels can be achieved.

Combustion control optimization
The advanced combustion control system can monitor and adjust the operating status of the burner in real time to ensure its stable operation under the best working conditions. By optimizing the combustion control strategy, precise control of parameters such as fuel supply and air flow can be achieved, thereby improving combustion efficiency and reducing emissions.
