Jon, Wood Gassers burn very diferent than conventional wood boilers. (1) they are totally sealed without combustion air). All air is pumped in via controlled fan. (2) all combustion air is pumped into the wood holding chamber from the top and forced DOWN through small orifices, into a secondary burn chamber. These orifices similate a blowtourch which burns off the "smoke at 1200-2000F. {much the same as blowing on coals to start a fire.} This secondary gasification chamber literally burns all the heat energy that would normally be released back into the air as smoke in a conventional boiler. Smoke can amount to 50% of the heat , BTUs/LB in a peice of wood, that a conventional wood burner never converts to heat. Gassers don't recover all the BTUs , but emissions are very low, no visible smoke, and while in the "idle mode" (temp above low limit) there is no oxogen present- thus no smoldering wood/no smoke, as air flow is down in the unit and any lingering smoke is trapped in the wood chamber above the gasser chamber and flues. when core temp drops below set paramiters, generally a Delta T of 10F from a set point of 180F high side, the combustion fan will turn on or off. It is also very important to maintain a core temp of +140F, because below that condensation can occure and deterioration of the water jacket occures. Electronic sensors controlling circ. pumps or a compound manifold with mixer valve can control the low jacket temp problem. Low jacket temp also will affect when gassifacation ocures, depending on the quality of the wood. Jon, I might have confused you a bit, but think of this system like the injection/combustion systen in a 930 Case, Inject fuel into Precombustion chamber, blow it out into the cylinder and off you go.

Today's Featured Article - A Lifetime of David Brown - by Samuel Kennedy. I was born in 1950 and reared on my family�s 100 acre farm. It was a fairly typical Northern Ireland farm where the main enterprise was dairying but some pigs, poultry and sheep were also kept. Potatoes were grown for sale and oats were grown to be used for cattle and horse feeding. Up to about 1958 the dairy cows were fed hay with some turnips and after that grass silage was the main winter feed. That same year was the last in which flax was grown on the farm. Flax provided the fibre which w
