Hi i am new here. I Am setting up a Coal/biomass fired firebox fire tube 3-pass Boiler for heating barns and such. It will be set up for heating water to 160-180 degrees F. The boiler is rated at 4,000,000 btu/hr and my question is, how much CFM should i spec the induced draft exhaust fan and multicyclone separator. Is there a ratio out there for BTU to exhaust CFM. Any help is appreciated. thanks.
