It is difficult to raise the temperature at the outlet of the 200,000-liter diesel hydrogenation heater

Regarding the issue raised, the original poster likely assumes that increasing the temperature of the heating element is sufficient to raise the outlet temperature of the medium furnace. 2. From the description of the problem, it can be seen that the approach used for adjustment lacks consistency, and the experience gained cannot be replicated. 3. The heat transfer process relies on a balance between demand and supply; here, demand refers to the amount of heat required by the medium, while supply refers to the heat supplied by the fuel. When there is a balance between these two, the temperatures of both remain relatively stable. When supply exceeds demand, the temperature of the medium rises. 4. Regarding the question raised by the poster, if increasing the heating in the furnace still does not raise the temperature at the outlet of the medium, it is likely that the heat input to the furnace is not sufficient to meet the medium’s heat requirements. 5. As for the claim that opening the fire viewing port can increase the outlet temperature of the medium-fired furnace, this is achieved by adjusting the distribution of heat within the furnace, and it is based on the principle of supply and demand balance. 6. The heat distribution in the furnace takes place within a complex flow field; sometimes increasing the air supply can help direct heat toward the furnace’s outlet, but this does not mean that more heat is supplied to the furnace. To some extent, an increase in oxygen content leads to a decrease in the furnace’s efficiency. Only on the basis of complete combustion achieved through proper air distribution is it reasonable to increase heating to meet the medium’s heat requirements

Could we add WeChat to discuss it in more detail?
