Introduce highly flammable gas from gasification into the sulfur recovery unit
Thread Content
Why does the heat in the flue gas furnace shift backward after high-flash-point gas from vaporization is introduced into the sulfur recovery unit?
High-flash-point gases are all burned in the middle section of the incinerator
Is hydrogen sulfide completely burned? Is it mixed with unburned hydrogen sulfide after combustion?
What kind of gas is high-flash-point gasification gas? Flash steam? I’ve never heard of it.
What the original poster is referring to is sulfur recovery in the coal chemical industry. Vaporized flash steam refers to the gas coming from the high-pressure flash tanks in the gas chemical processing section, with hydrogen, carbon monoxide, carbon dioxide, and other substances as its main components. The apparent shift in heat that you observe is merely a superficial phenomenon; it can be understood as follows: the vaporized flash steam enters after hydrogenation, compared to before. The amount of gas being heated remains unchanged, but the amount of gas that supplies heat (the gas after combustion) increases; moreover, the combustion of the incoming gas also generates heat. Active participation
I understand that the system pressure increased, which shifted the combustion area backward.
