Was curious about the theory or opinions on this. Concerning draft and/or rising heat out of our stoves. The more air flowing through the coal bed, usually dictates the intensity of the fire. More air equals more heat. (Providing enuff fuel to support it). Air in usually also requires air out. I've been skooled here that, if we close down our MPD, then more heat will be retained into the stove. (Makes sense to me). However, if closing the MPD slows down the draft, then the stove can't produce the required amount of heat to build the fire. I'm wondering about which phenomenon has a larger potential for heat output. Close down the MPD, to retain heat, but lose the higher draft, or open the MPD for a higher draft, but send the hot air up the chimney? Which is the preferable method?
Well,being I'm a Combination of an Aspiring Alzheimers' Patient/Concentration Deprivation Candidate,and just a General Mental Trainwreck,Look Out,here's my take..... The Fuel dictates the Flow Method of Control. The Stove Design and Total Thermal Mass available to radiate outward allows the heat produced to leave the unit,thereby getting the most productive heat output from the stove without sending heat up the flue. Baseburners come to mind.Keep in mind that the MPD and Baro are tools of Flow Control. Their Complimentary Tools are your Combustion Air Inlet Controls. If the Stove has been constructed and maintained as an Air Tight,Theoretically those Control Tools are the only way to conduct flow. So the preferable method is no single method is ultimately correct. Sorry to do it to you,but the MPD has carried the day forever. It went as far as it could. It seems to me that the Baro was developed to compensate for Windy,Gusty Days trying to suck or draft the Living Daylights out of the Stove and its Fuel Supply. The Stove lacked the ability to Control Combustion Air due to the Higher Vacuum trying to pull through the Stove.....I love definite situations,but this one seems to be an Eternal Grey Area. In closing,I'm so full of crap that my eyes are brown!
