Reforming furnace

What is the impact of shutting down the waste heat boiler on reforming and the unit?
After the waste heat boiler is shut down, in order to protect the furnace tubes, the heating furnace is cooled down; sometimes even the furnace itself is shut down and feed is stopped. The low-load operation of the recycle hydrogen compressor on the unit side is permitted, the compressor is shut down, the dry gas seal is replaced with nitrogen, and the steam generated by the waste heat boiler is disconnected from the medium-pressure steam network. In simple terms, if the waste heat boiler stops operating, the entire plant stops operating as well.
No heat. There’s no talk of waste heat then
