What are the causes and hazards of water in the process gas of the gasification furnace?
See what kind of furnace it is. The reasons for the differences in furnace structure and process systems vary, but the methods and approaches for analyzing problems remain the same. I. Where does water come from? Is any abnormal water entering the process gas, or are the water addition parameters deviating from the specified values? Second, are the water removal facilities along the process gas path functioning properly? Including liquid level, water removal baffle, trays, etc
Reasons for water in the gasifier: high gasification load, inappropriate gap between the downcomer and the upcomer or severe ash accumulation, severe ash accumulation on the baffle plates in the gasifier, and poor quality of the quench water； Water in the process gas from the vaporization unit may be caused by problems with the wash tower trays or baffles. Risk associated with water: It is difficult to control the liquid level in the vaporizer, and there is a risk of shutdown due to an excessively low liquid level. Excessive water carried in the syngas to the shift unit may cause the shift catalyst to become pulverized
Is it because of the high operating temperature of the vaporization furnace?
What are the causes and hazards of water in the process gas of the gasification furnace? The main reason for water in the process gas is the low reaction temperature inside the furnace, which leads to a reduced rate of steam decomposition ； Of course, it will cause certain harm in the future.
