How to prevent freezing and condensation in the catalytic external heat exchanger?
Thread Content
I would like to ask the experts: how can anti-freezing and anti-condensation measures be implemented for the catalytic external heat exchanger? If the main unit is turned on and the furnace is activated, what is the maximum allowable temperature?
Regarding the prevention of freezing and condensation in the catalytic external heat exchanger, let me share my views. During shutdown in winter, the regenerator’s temperature drops below 400°C; at that point, the external heat exchanger is disconnected from the system, and air is allowed to flow through it, using the residual heat to dry out any remaining water vapor. We are all discussing this plan; we plan to conduct the experiment during the next shutdown
There have been cases in the past where ignition was done at the bottom using liquefied gas, but safety must be taken into account. As for using an auxiliary combustion chamber, the main fan has to be turned on. Heating with a steam coil is also possible……
