CASCADE CALC GENERATOR CALC
BOILERCALC MULTIPLECALC
Our FlueCalc software accurately calculates chimney size based on a number of factors we take into
consideration. These include (but are not exclusive of) plant application, flue gas volume, overpressure
available, loss/friction for bends and tees, cowls and temperature release from the boiler. With this
information we can determine the best chimney size for your application.
