Why is it necessary to maintain a temperature of 150 to 250 degrees at the bottom of the vent flare behind the incinerator?
Reply to 1# Crispy Sausage: Is it absolutely necessary to reach the temperature you mentioned?
150-250. This temperature is a bit low, isn’t it? What height is the dust? What is its structure? Participate actively
This is related to the design height of the chimney, especially in the case of steel burners. It is necessary to ensure that the exhaust gas exiting the burner does not cool the water vapor at the top of the chimney, thereby preventing the formation of sulfurous acid; that’s how I understand it
If it is to prevent dew point corrosion of chimneys, are there still such requirements for concrete chimneys? Is it also necessary to design a lining inside the cement chimney to prevent corrosion? Furthermore, if dew point corrosion is not taken into account, the flue gas temperature can be reduced further, allowing more waste heat from the flue gas to be recovered, which is beneficial for energy savings.
To prevent dew point corrosion. This temperature is way too low; our requirement is at least 280℃
Reply to 1# Crispy Sausage: OP, that temperature seems a bit low. It depends on the dew point temperatures of SO2 and SO3; the dew point temperature of SO3 is over 240 degrees, while that of SO2 needs to be checked
