ABSTRACT:
The safety stove includes a stove body having a heating chamber and an air chamber therein. The stove body and chambers are pneumatically sealed. The heating chamber is positioned between the stove top and the air chamber. A burner assembly is mounted beneath the stove top in the heating and air chambers. The burner assembly has a fuel inlet and an air/fuel mixer and a burner. The burner being in the heating chamber, the fuel inlet being in the air chamber. The air/fuel mixer extending between the chambers. The burner assembly is the sole communication between chambers. The chambers are pneumatically isolated from the body. An air inlet duct communicates with the air chamber and the exterior of the body. A combustion product exhaust duct communicates with the heating chamber and the exterior of the body. The heater chamber and the product exhaust duct define an air/combustion product flow path. A fan is mounted within the air/combustion product flow path. The burner flame is isolated within the body and the flow path is isolated from the exterior of the body. When the stove is used in explosive atmospheres, both the air inlet and the combustion product exhaust ducts communicate with the exterior. In a motorhome or camper application, the air inlet duct may communicate with the interior of the motorhome or camper, if desired.
