Low Temperature Heat Recovery for Boiler Systems
Abstract
Low temperature corrosion proof heat exchangers
designed to reduce boiler flue gas temperatures to
150°F or lower are now being commercially operated
on gas, oil and coal fired boilers. These heat
exchangers, when applied to boiler flue gas, are
commonly called condensing economizers. It has
traditionally been common practice in the boiler
industry to not reduce flue gas temperatures below
the 300°F to 400°F range. This barrier has now been
broken by the development and application of
corrosion proof heat exchanger technology. This
opens up a vast reservior of untapped recoverable
energy that can be recovered and reused as an energy
source. The successful recovery of this heat and
the optimum use of it are the fundemental goals of
the technology presented in this paper. This
Recovered Low Level Heat Is Normally Used To Heat
Cold Make-up Water Or Combustion Air.
