| Abstract: | IGCC unit gasifier oxyge n shut-off valve is the gasification furnace oxygen fuel supply control valve, which is the single-point jump interlock of the gasifier, in order to ensure the safe operation of the equipment, when the equipment is abnormal or the valve control equipment is faulty, the valve is fast. At the same time, it is easy to cause the valve to malfunction due to the abnormality of the control equipment, causing the gasifier to stop or even the IGCC unit to stop. This paper discusses how to optimize the optimal and most economical control of the gas shut-off valve of the gasifier to prevent it. The misoperation caused non-stop, and achieved the expected purpose after the implementation of the final optimization and transformation plan. |
