The Model CFC boiler is a single pass,
vertical down fired durable firetube
boiler. The internal extended-heating
surface tubes provide very high levels of
performance in a compact space,
offering over 10 square feet of heating
surface per boiler horsepower, providing
many years of trouble free performance.
Tubes and tube sheets are constructed from UNS S32101 duplex stainless steel.
Tubes feature AluFer tube inserts for optimal heat transfer.
The extended heating surface design provides the ideal solution for the demands of
a condensing boiler and helps to recover virtually all the latent heat of the flue gas.
Each tube consists of an outer stainless steel tube (waterside) and the AluFer
extended surface profile on the flue gas side.
With the extended heating surface tubes the CFC boiler will provide fuel to water
efficiency of up to 99% at low fire and 97% at high fire with 80 degrees F return
water temperature.
The powder coated steel casing is designed for easy removal and re-assembly. As
shown in Figure B5-2, the burner is hinged and is provided with hydraulic pistons
for simple opening for service of the spark electrode, inspection of the burner
cylinder, tubes and tube sheet on Models CFC1000 and larger. (On the CFC500 and
750, the burner is hinged only). A front mounted service platform is provided for
easy access to the burner components and controls.
ISO 9001:2001 certified manufacturing process ensures the highest degree of
manufacturing standards are always followed.
ASME Code construction ensures high quality design, safety, third party inspection,
and reliability, and is stamped accordingly.
The burner utilizes "Premix" technology to mix both gas fuel and combustion air prior
to entering the burner canister, with air "leading" during burner firing transitions.
