Ask: Causes of booster shutdown and solutions
Thread Content
Yesterday, when the booster stopped operating, the external heat extraction liquid level rose sharply. By the way, to whom is the air from the booster pump supplied?
For external heat extraction fluidized air, used to boost the air flow in the raw material riser pipes.
The pressurized air should be supplied to the fluidization air of the external heat exchanger and the fluidization air of the catalyst bed distributor. Pressure booster shutdown – Symptoms: 1. The flow rates of the air used for external heat extraction and for fluidizing the catalyst distributor drop to zero. 2. The amount of heat extracted externally decreases, causing the temperature of the regenerator to rise. 3. The density of the material in the external heat exchanger as well as that of the catalyst distributor increases. 4. The oxygen content in the flue gas decreases. Solutions: 1. Immediately activate the main air supply to compensate for the loss of pressure-enhancing air. 2. Identify the cause and start the backup pressure booster as soon as possible. 3. If the temperature of the regenerator becomes too high, it is possible to reduce the amount of feed material fed into the reactor
