[quote="stokerscot"]No, I have too many now. I'm not really concerned with a couple percent efficiency. When oil was a buck a gallon(seems like yesterday) I wouldn't have changed my 87% oil boiler out with a higher rated appliance. It just didn't pay. Same with coal. At the prices for these machines it isn't a concern to get a couple percent better efficiency. A couple ton more isn't going to break the bank, yet.
Your efficiency will not go up or down with them they do Nothing but get in the way when cleaning out the tubes and Collect Flyash it was a design that never worked a waste of metal
I think you might be wrong. The plates serve as a device to keep the intense coal heat from getting sucked out the chimney as fast. All it takes is a simple experiment, check the stack temp without the baffles for a 24 period in the winter and then again with the baffles in place, no other changes. I'll bet the stack is cooler with the baffles in place. No way would EFM continue to put 100 or so extra pounds of expensive steel into the boiler if it wasn't necessary, most customers surely wouldn't complain if they were omitted. As far as removing them for cleaning, how often does it need to be cleaned out, once every year at the most? I'd leave them in as EFM designed.[/quote]
Ed we are not talking about the baffle plates we are talking about the spiral Pieces of metal that went in the older tube boilers that EFM made They where to act like a heat sinker to help keep the heat in the tubes longer they really did not do anything but get in the way when you where cleaning the tubes out you had to take them out most people don't even know about them and the ones that did took them out
