Power surge causes the coking radiation pump to trip. How to deal with the heating furnace?

Turn on the steam pump to replace radiation. If it fails, the coking oven will cut off the main gas, keep the continuous light on, and increase steam injection. Personal opinion.

1. Turn off the heating furnace and keep the light on

Was it a sudden jump? It should be possible to start a backup operation. The coking furnace should cut off the main gas, keep the lights on, and increase the steam injection.

1. If the pump suddenly stops, instead of stopping due to power failure that causes all the pumps to lose power, the backup pump can be started immediately. . . 2. If there is a sudden power outage in the entire plant, it must be handled in accordance with the operating procedures and emergency plans formulated by the company. Generally, it is necessary to start the steam pump to maintain pressure, quickly extinguish gas and other fire sources, and only burn the light to wait for the call. ； If there is no call for a long time, just follow the principle of stopping work and taking a break to deal with the device. . . :lol

Increase the water and steam injection, and the heating furnace should be cooled down in an emergency to keep the light on. Restore the radiation as soon as possible. The steam pump cycle cannot be restored for a long time.

The third option should be chosen because the backup pump needs to heat up quickly after it is started, and a certain furnace temperature should be retained even when the line is shut down and cleaned. Just make sure that the heating furnace tube does not coke.

It's just that the radiation pump has tripped. The furnace can be cooled down immediately without turning off the flame, and the gas injection can be increased. Since it is a power failure, it can be restarted immediately.

Cool down the heating furnace and immediately turn on the steam injection； If there is a power outage, it is easy to cause the entire plant's public works to stop (unpredictability). Steam is very important for heavy oil equipment such as coking. Otherwise, you will be in trouble when the steam is gone after you finish your work. In coking, you must pay attention to the steam rush in the case of plant-wide power outages, power outages, and purification air outages (purely personal experience, everyone is welcome to share) ； Several principles for handling accidents in heating furnaces 1. Residual oil cannot stay in the furnace tube 2. The furnace tube does not coke 3. Low-temperature residual oil does not enter the coke tower 4. The heating furnace outlet system does not hold pressure

You should choose the 3rd option. The key problem is that the furnace tube does not connect. It is better to design a plan according to the process of your own device. If this happens here, increase the steam injection and start the standby pump immediately. If the standby pump cannot be started, the outlet of the love tube should be fully opened to sweep the line with steam, and at the same time preheat the reciprocating pump.

If the power is just dazzling, the call will come in a short time or instant. At this time, while ensuring that the heating furnace tube does not coke, we must also consider quickly returning the device to normal. What I personally think should be paid attention to: 1. The coking oven immediately increases steam injection to the maximum amount. 2. Turn down the main gas regulating valve indoors and keep the continuous light on. 3. Go to the site immediately to start the feed pump. If the feed pump has a self-starting protection function, it is best to start the feed pump without closing the outlet valve. (The external operator goes to the installation site and turns on the pump normally, and the maximum time should be within 1 minute. If the feed pump has a self-starting protection function, it is 30 seconds.) 4. The internal operator quickly raises the gas and raises the temperature of the heating furnace.

3. Close the main gas regulating valve of the coking furnace to the minimum in the room (so that it will not go out), keep the continuous light on, and increase the steam injection. I would like to ask if the feed at the furnace outlet is still fed according to the original flow and the bottom of the tower should not exceed how much during this period to cause the low-temperature viscous oil to fall back? How much is the general increase in gas injection volume? If the production tower encounters this situation in the later stage, will increasing the gas injection volume cause the tower to collapse (our device does not have a neutron level meter: L)? Newbie: P Please give me some answers.

Cool down the heating furnace, increase water or steam injection, activate the backup pump (you can also restart the original pump, but it must be fast), and then gradually restore the furnace temperature after the flow rate becomes normal.

Summarizing so many emergency measures, in fact, the solution is to install an anti-shock power module. To ensure that the equipment does not shut down, there is no need for emergency treatment. .
