Forced Draft Fan Sizing For Fired Heaters / Boilers

Forced Draft Fan Sizing For Fired Heaters / Boilers

Air leakage would therefore need to be included for ID fan sizing and for heat transfer calculations, but not for FD fan sizing. The burner draft loss seems reasonable for a fired heater, but would be low for a register type burner fitted to a fired steam boiler, when I used to size them we allowed 150 mm wg for register draft loss.
