In this paper, after thermal power plant 300MW boiler was studied, mat lab was used to write calculation program about heat transfer process between the main steam and boiler flue gas and amount of water was calculated to ensure the main steam temperature keeping in target temperature. Huang, Zhenqun Li, Ruyan Feng, Zhongbao Wang, Songhan Li, Wenbo Cheng, Jiwei Jin, Yingai Simulation and analysis of main steam control system based on heat transfer calculation Attention is given to methods for analyzing the filling and cooling of conduits and tanks by cryogenic liquids and ways to intensify heat transfer in these conditions are examined. General relationships are presented for heat transfer in cases of film, transition, and nucleate boiling, as well as for boiling crises. The single-phase-flow studies involve the investigation of gaseous and liquid heat-carriers in pipes, annular and plane channels, and pipe bundles in cases of cooling and heating. Methods are examined for calculating various conjugate problems of heat transfer in channels and closed vessels in cases of single-phase and two-phase flow in steady and unsteady conditions. ![]() Methods for calculating conjugate problems of heat transfer ![]()
