Hi Everyone,
Question regarding Boiler Controls , if anyone would like to chime in. I work for a Boiler OEM where we manufacturer our own Boilers we use siemens and honeywell burner management systems. Now occasionally we will provide a package of 2 or more boilers. If so we provide the customer with duplex boiler sequencer panel, primary boiler would call on secondary if the primary load draw is above a certain percent. Now the 2 boilers that we provide are sized the same so we can generate the same firing rate using header pressure in our PID loop in we output the Firing Rate via a 4-20mA connection to each boiler. We cycle the standby on as necessary based of the primary boilers load demand. One particular customer only wants one of our units but wants sequenced control with an existing boiler that he has on site. the problem is that our boiler is 200 BHP and the existing is 150 BHP. My question is can we proceed in a similar fashion that we do and send both boilers the same firing rate, or would I have to essentially ramp up the standby primary boiler to match the " btu output " of the primary?
