QSense™ Waste Heat Recovery Systems

Overview:
Efficiently recover valuable waste heat BTU’s from hot gases to heat water or other liquids the direct contact way with
a QSense™ Heat Exchanger. An optimal solution to reduce energy consumption and save on expensive fuel costs,
while at the same time cleaning the flue gas contaminants and reducing the exhaust temperature.
This highly efficient counter current flow exchanger can be used for process heating applications or to meet or
supplement building space heating needs. Almost any hot waste flue gas source can be used originating from
process or power sources including boilers, kilns, ovens, dryers, thermal oxidizers and incinerators.
The QSense™ Heat Exchanger is offered in a vertical configuration for maximum space savings and with all
necessary system components for complete one source responsibility.
For flue gases containing acid contaminants the unit can be equipped with neutralizing chemical reagents.
For particulate laden gas streams, a pre-scrubber and clog resistant contactor is available.
How it Works:
Air supplied by a blower (1) is raised in temperature by
the heat source (2). The hot gas enters the direct
contact exchanger inlet (3) and travels upward through
a high efficiency packed bed (4) with over 30 sq. ft./cu.
ft. of active heat transfer surface area. Cool water is
introduced at the top of the unit through a liquid
distributor (5) where it comes into intimate counter
current contact with the hot gas in the packed bed as it
travels downward. Sensible heat transfer between the
colder water and hot gas occurs resulting in rapid heat
up of the water. The heated water drains into the
sump section (6) and is pumped (7) through a plate
and frame or shell and tube heat exchanger (8) to
reheat return heat transfer liquid in a complete closed
loop cycle. Cleaned reduced temperature gas now
saturated with water vapor exits out of the top of the
unit (9).
