Lot's of ways to skin a cat Goose. I would imagine that in this particular layout, Siggy was approaching it from the standpoint of integrating wood with a modern boiler system already in place. I haven't studied the schematic that closely as I usually just glean an idea or two from any of them. Every job presents a different set of circumstances and I've yet to do two jobs the same.
Here's the part that lit me up and it's the most important thing you can do for efficiency.............."Most wood-gasification boilers have variable-speed combustion air blowers that can partially throttle the combustion process when the water in the boiler reaches a set high-temperature limit. However, the highest overall combustion efficiency is achieved when a full load of wood is burned at the maximum combustion rate possible, as determined by the blower’s capacity. This results in a “burst” of heat output that lasts as long as it takes to burn off a firebox full of wood (usually two to four hours). "
