“…Their function is to complete the energy form transformation of fuel from chemical energy, to the thermal potential energy of steam, then to mechanical energy, and finally to electric energy. Boiler, steam turbine, and generator are called the three main equipment in thermal power plants [5][6][7][8][9][10][11], other auxiliary equipment of production system includes the coal delivery system, the chemical treatment system of water, and the slurry discharge system, etc. These systems cooperate with the main system to complete the task of electricity production [12][13][14][15].…”

To keep the main system and the auxiliary equipment of production system of thermal power plants operating normally, it's a necessary work to fully consider the periodical repeat features of thermal process when modelling the thermal process based on thermal state data of machine units. Since most equipment in power plant work in an electromagnetic coupling environment, a too high ambient temperature will affect the safe operation of units, so when studying the dynamic features of multi-modal thermal process of power plants and their soft environment, the temperature distribution features of multimodal thermal process should be classified. To solve these questions, this paper established a model for the coupled temperature field during multi-modal thermal process and studied its analytical solutions. At first, this paper proposed a multi-modal modelling method for solving the distribution features of coupled temperature during multi-modal thermal process, the method can quickly determine the optimal number of local models of multimodal thermal process of power plant units while reducing the computational load of the coupled temperature field model. Then, this paper introduced an improved niche method into the basic cross-entropy optimization algorithm and used it to solve the layout optimization problem of coupled temperature field during multi-modal thermal process. At last, the validity of the proposed method was verified by experimental results.

“…The T24 steel, with 2.4-wt% Cr, has a maximum service temperature limited to 575°C according to ASME Code Case 2540. Otherwise, the T92 and VM12 steels, with 9-and 12-wt% Cr, [12,13] have a maximum operating temperature of 600°C and 620°C, respectively. These ferritic steels have been described deeply in previous works.…”

The corrosion mechanisms of T24, T92, VM12, and AISI 304 steels are studied under the influence of NaCl–KCl, NaCl–Na2SO4, and KCl–K2SO4 salt mixtures in a dry air atmosphere at 650°C for 15 days. NaCl–KCl was the most aggressive deposit and AISI 304 stainless steel exhibited the highest corrosion resistance. There was no relation between the Cr content of the ferritic steels and their corrosion resistance in NaCl–KCl. In contrast, the resistance of high‐Cr steels was better when exposed to NaCl–Na2SO4 and KCl–K2SO4. The high‐Cr and the low‐Cr steels were more susceptible to NaCl–Na2SO4 and to KCl–K2SO4, respectively.
