Abstract

A heat exchanger system capable of being modulated for cooling hot dust-laden flue gas having an elevated dew point is provided comprising, a heat exchanger formed of a vertical cylindrical shell containing a bank of tubes vertically disposed therein coupled to tube manifolds at opposite ends thereof such that the bank of tubes communicates with a hot gas inlet and a hot gas outlet coupled respectively to said manifolds each of said tubes being surrounded by a tube to provide annular spaces having manifolds communicating therewith through which air is circulated in said heat exchanger in concurrent flow with said hot flue gas, means being provided for maintaining a flow of hot flue gas through said heat exchanger to a downstream line, including a closed circuit air line with a blower for maintaining a flow of air through said heat exchanger in concurrent flow and heat exchanging relationship with said hot flue gas, valve means and temperature-sensing devices being provided in the system to control the air flow and thus the temperature of the heat exchanger at above the dew point temperature of the cooled flue gas.
