CASCADE CALC GENERATOR CALC

BOILER CALC MULTIPLE CALC

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.
