Raw gas compressor trip

The opening degrees of the forced draft fan and induced draft fan are 36 and 31 respectively, which is normal. After the feed gas compressor trips, it’s necessary to ensure that the temperature in the reformer remains above 650°C. To increase the amount of fuel gas, should the forced draft fan and induced draft fan be opened wider or closed down at this time? Should it remain unchanged? Why? It takes over 10 minutes for the standby unit of the feed gas compressor on our side to start up.
In practice, increasing the fuel gas flow does not cause significant changes in the negative pressure inside the furnace; there is no need to operate the forced draft or exhaust fans. If you really want to make some adjustments, simply increase the settings for all of them. By the way, is the method used to deal with the shutdown of your raw material compressor to increase the furnace temperature rather than lowering it? Who taught you?
The exhaust fan is used to regulate the negative pressure in the furnace (it functions in a similar way to the flue dampers), while the blower is used to adjust the oxygen level (it functions similarly to the air valves). The fuel gas, on the other hand, is used to control the temperature of the furnace
The handling method doesn’t seem quite appropriate; we should stop feeding the raw materials. It’s necessary to reduce the gas level – adjusting the blower fan to achieve an appropriate negative pressure will help minimize the impact on temperature; it’s mainly the gas that’s a problem!
The converter should not be shut down; it needs to be cooled down, but its temperature must remain at a level that allows methane to be introduced, right?
