Abstract (en)
[origin: WO2018152394A1] A method of controlling operation of a furnace having a pre-mixed burner, a heat exchanger, and an inducer blower downstream of the heat exchanger includes monitoring a pressure drop across the heat exchanger. The speed of the inducer blower is controlled in response to the monitored pressure drop to thereby control mass flow through the furnace.
