Abstract
A boiler including a water jacket surrounding upper and lower combustion chambers for receiving heat for heating water or other fluid therein, which chambers are defined by a refractory structure that extends entirely across the inner casing. A vertical passage through the refractory structure provides for flow of combustion gases from the upper to lower combustion chamber. Oxygen is provided through a first forced air inlet to the upper combustion chamber for burning of wood or biomass, and is provided through a forced air passage in the refractory structure and opening into the vertical passage thereby providing at least one second forced air inlet for burning of the combustion gases and particulates passing therethrough. The refractory structure sealingly engages the inner casing in a manner to seal the upper combustion chamber from the lower combustion chamber so that the upper combustion chamber can be made substantially air tight.
