Combustion chamber and quenching chamber
Thread Content
Is a high pressure difference between the combustion chamber and the quenching chamber of the Texaco gasifier due to a blocked quenching ring?
No, it has nothing to do with the quenching ring. The pressure difference between the combustion chamber and the quenching chamber refers mainly to the pressure difference at the slag outlet – it’s necessary to check whether that outlet is blocked. Additionally, factors such as the outlet for syngas, the gap between the downcomer and the upcomer, and the liquid level in the gasifier come into play, but the likelihood of problems occurring with these latter factors is low
The poster must have just started working in the coal chemical industry, right?
Well, I just graduated this year; I’ve been studying for a little over two months now, and I feel lost and worried!
Same question: how does the pressure difference between the two affect the operating temperature of the vaporization furnace?
Can it be explained in this way: the pressure difference between the two increases, which means that the high-temperature gas stays in the combustion chamber for a longer time. In terms of heat output, gas serves as the medium for delivering heat; since the gas stays in the combustion chamber for a longer period of time, the rate of heat output slows down. As a result, more heat remains in the combustion chamber, which is reflected in an increase in the furnace temperature.
