It seems very troublesome if the internal heat coil is leaking inside. It is difficult to judge and deal with it.
Can the original poster also upload the correct answer?
There is no standard answer, haha. Sorry, but I can talk about the first two questions. Welcome everyone to add - 1. The operation of the hydraulic slide valve to the mechanical hand crank. Answer key: Contact the internal control to automatically change the regeneration slide valve to manual control, turn the hydraulic system "MV6" to the "lock position", turn the switch handle from "hydraulic" to "manual", turn the handwheel during the pulling process, turn "MV5" to "manual", and then turn the handwheel to open and close the regeneration slide valve. 2. Regenerator unloading balancing agent operation. Answer key: Stop small-scale feeding, check the scale of the balance agent tank, fully open the unloading line throttle valve (the 4th valve from the wall valve) to the gate valves of the balance agent tank, contact the dispatcher to put the vacuum pump into use (steam dehydration before putting into use), provide loose air in front of the throttle valve, fully open the 3rd valve, 2nd valve in sequence, the 1st valve has been secured Keep it normally open, supply air to the 4th valve, open the 4th valve and observe the unloading temperature. At the beginning, preheat the unloading pipeline and slowly increase the temperature. Gradually open the 4th valve, adjust the loose air to control the unloading temperature to not exceed 500°C, and check whether there is any leakage in the unloading line (including the plate heels of each gate valve).
