Abstract
Method and apparatus to determine the skin-temperature of heat-exchange tubes and to prevent overheating of the heat-exchange tubes in a process gas heater (where extreme conditions prevent obtaining sufficiently-accurate direct thermocouple or pyrometric measurement to reliably prevent such overheating) by calculating the maximum skin temperature of heat-exchange tubes using preferably real-time calculation of the overall heat flux through the walls of the heat-exchange tubes with preferably real-time values of gas composition and gas temperature at the inlet and at the outlet of the tubes to calculate the overall transferred heat; and by periodically measuring the temperature of the gas flowing through each of the heat-exchange tubes, and using the measured gas temperatures for calculating the skin-temperature of all tubes, or of a tube selected for the highest gas temperature using the equation:
