In this context, thermal power plants, especially coal-fired power plants, operate at frequent load changing and low-load modes, resulting in challenges including reduced safety, reduced efficiency and increased pollutant emissions [3]. Digitization and smart power plant development provide an effective way to alleviate the challenges with coal-fired power plants is the emission of pollutants, especially for NO2 and NO (collectively referred to as NOx). Today, NOx emission is regulated and has become an important consideration in the design and modification of coal-fired utility boiler[1-2]. However, many old-designed utility boilers in China emit the NOx pollutantsMulti-objective Optimization of Coal-fired Boiler

Introduction. Steam cycles have been used for electric power generation from coal since the early 1900’s. These first coal-fired power units featured outputs in the range 1–10 MW and the steam generator already included an economizer, an evaporator, and a superheater (Harvey et al., 2020).According to the same reference, the first steam cycle had an Accurate modeling of thermal power plant is very useful as well as difficult. Conventional simulation programs based on heat and mass balances represent plant processes with mathematical equations. These are good for understanding the processes but usually complicated and at times limited with large number of parameters Prediction of power output of a coal-fired power plant by

In order to provide more grid space for the renewable energy power, the traditional coal-fired power unit should be operated flexibility, especially achieved the deep peak shaving capacity. In this paper, a new scheme using the reheat steam extraction is proposed to further reduce the load far below 50% rated power. Two flexible operation For coal-fired power plants, operational flexibility is the rapid power response capability for frequency regulation, which usually demands the activation of thermal storage in power units. Thus, boiler-turbine coordinated control, which mainly uses the thermal storage in the boiler system, is a popular strategy to regulate steam turbine Improving operational flexibility by regulating extraction
