Learn MoreJun 01 1996 · The CEMS flue gas flow rate monitor is suspected to be one of the factors contributing to this high bias. Since the flue gas flow rate monitors are certified and calibrated using EPA Methods 1 and 2 there is concern that the bias is not from the flue gas flow rate monitor directly but rather from the Methods 1 and 2 procedures.

Learn MoreAn increase in total flue gas mass flow inside the furnace and boiler part up to the take off point which assists with more heat transfer to the superheater the reheater and the economizer. (ii) A reduction of overall flue gas temperatures due to readmission of colder flue gas.

Learn MoreFor some boilers gas dampers are provided in the common flue gas path as the FCEs for reheater steam temperature which when positioned acts as a three-way proportioning valve that takes the task of apportioning the flue gas flow through both the superheater and reheater banks. This means that the total flue gas flow would be uninterrupted ...
