Question 1: What is the designed temperature of the process gas at the waste heat boiler of the reaction furnace? Why? What does it indicate if there is a significant drop or rise in this temperature? Answer: The designed temperature of the process gas at the outlet of the reactor waste heat boiler is 318°C. Given the designed concentration of acidic gases and the operating load, this temperature prevents sulfur from condensing at the outlet of the reactor waste heat boiler. Therefore, the heat exchange area of the waste heat boiler was calculated to ensure that the temperature remains at 318°C under the designed load of the plant. If there is a significant drop in temperature, and such a drop occurs over a short period of time, it may indicate that the tube bank in the reactor’s waste heat boiler has burst; this situation requires prompt verification and handling ； Under normal operating load of the plant, if this temperature rises significantly, it indicates a decrease in the heat exchange efficiency of the reactor’s waste heat boiler; this could be due to scaling on the tubes of the waste heat boiler, which reduces its heat exchange efficiency.
The designed temperature of the process gas at the outlet of the reactor waste heat boiler is 318°C.

Answer: The designed temperature of the process gas at the outlet of the waste heat boiler in the reaction furnace is 318°C, as the acidic gas in the system is designed to be at this temperature
