Hybrid PF
Solid Fuel Fired Boiler
The Hybrid PF design is suitable for applications to
produce high pressure steam or hot water in ranges from 3,450 - 60,000 lbs/hr
(3.4 mm BTU - 60 mm BTU) output from 100 up to 400 PSI. This system is designed
by HBC to combine the best technologies from the "old school" of
biomass combustion and the latest advanced combustion control technologies.
HBC's Pneumatic Feed Stoker Systems have proven their ability to provide
a very low turn-down rate making it particularly suitable for heating applications
in lumber dry kilns, veneer log vats, veneer dryers, greenhouses and factories.
This combination enables these systems to provide a flexible and reliable
operation utilizing a consistent "grade" of biomass waste with
low moisture contents ranging from 8 - 20%. Ash removal is a manual operation.
The boiler vessel is a two pass hybrid design incorporating a water tubed
boiler-type water membrane and a two-pass fire tube scotch marine vessel.
This vessel's advantages over standard water tube boilers include much larger
steam disengagement area providing high quality steam, larger steam storage
capability for quicker response to sudden steam demand and much larger thermal
storage that provides fast demand response times and safer operation.
