Temperature of raw gas after quenching
Thread Content
To prevent excessively high temperatures, what is the general maximum temperature allowed for raw gas after quenching?
Is the poster referring to a furnace that uses water-coal slurry, or some other type of furnace? For water-coal slurry, the temperature during gas cooling is around 260-270 degrees Celsius; if I’m not mistaken, an alarm should be triggered when the gas outlet temperature exceeds 300 degrees
Yes, in the downward cooling process, the temperature isn’t as high as 260. Currently, the amount of cooling water used in the water-coal slurry boilers in use in China is generally set at its maximum level; one industrial plant has a temperature of around 225 on its DCS system. I’m not sure what temperature other companies maintain
Is this the temperature range controlled during the actual operation of your device?
In a water-coal slurry furnace, if the temperature of the gas exiting the quench chamber is only 200–220°C, then the operating pressure of such a furnace is likely to be relatively low, perhaps around 20 kilograms per square centimeter. For water-coal slurry with a density of 65 kilograms per cubic meter, the temperature of the gas exiting the gasification furnace under normal operation is 260–270°C; after passing through the wash tower, the temperature of the gas before it leaves the system is around 230–240°C
Our chain value is 266; the shutdown occurs at high temperatures, usually around 210
300 for jumping out of the car; usually 230 to 250
