ABSTRACT:
An open hearth boiler includes a body intended to be positioned above an open hearth. Inflow and outflow pipes are connected to the body and to a central heating or hot water circuit. The body includes internal combustion chambers which contact the flames and combustion gases. The combustion chambers are spaced from one another and baffles between various chambers define a spiral internal circulation circuit for a heat exchange fluid in the body.
