A fluid fuel burning device, comprising: an elongated combustion compartment comprising side walls, where distal end is open allowing fluid communication from inside the combustion compartment and out of compartment; an insulation layer arranged on the inner surface of the side walls and/or on an inner surface of the proximal end of the compartment, preventing heat inside the compartment from radiating away from the compartment from the side walls and/or the proximal end, air flow means for providing a current of air, a fuel nozzle for aerification of the fluid fuel inside the combustion compartment, fuel feeding means for feeding fluid fuel to the fuel nozzle, pressure providing means for applying pressure to the fluid fuel fed via the fuel feeding means, and where the insulation layer comprises a heat absorbent layer that is of a temperature retentive material and radiating heat from the absorbent layer into the combustion compartment.
A fluid fuel burning device, comprising:
A device according to any of the preceding claims, wherein the elongated combustion compartment has an inner surface area having a first cross sectional diameter and a second inner surface area that has a second cross sectional diametre, where the first cross sectional diametre is smaller than the second cross sectional diametre.
A device according to any of the preceding claims, wherein the elongated combustion compartment has a first right circular cylindrical volume having a first cross sectional diametre and a second right circular cylindrical volume having a second first cross sectional diametre that is smaller than the first cross sectional diametre.
A device according to any of the preceding claims, where the inner end proximal end section of the combustion compartment comprises the fuel nozzle and an outlet for the fan ensuring that the air supply envelops the fuel nozzle for feeding oxygen in a direction parallel to the longitudinal axis of the compartment.
A device according to any of the preceding claims, wherein the fuel feeding means comprise a circulating fuel arrangement, the arrangement comprising a fuel tank, an output conduit from fuel tank, an input conduit into fuel tank, a driving arrangement for circulating the fluid, a regulator valve for regulating the pressure inside the circulating fuel arrangement, and a fluid input means for incrementing the amount of fluid inside the circulating fuel arrangement.
A device according to any of the preceding claims, where the device comprises an oxygen measuring means and/or a pressure measuring means arranged to measure the oxygen and/or pressure of the exhaust gas of the device.
A device according to any of the preceding claims, wherein the pressure and/or the oxygen measuring means has at least part control of the regulator valve.
A device according to any of the preceding claims, wherein the pressure and/or the oxygen measuring means controls the magnitude of air provided by the air flow means.
A device according to any of the preceding claims, wherein the fluid input comprises a water input means for introducing liquid water into the closed circulating fuel arrangement.
A device according to any of the preceding claims, wherein the thermal absorption layer is a layer of a material that has a high thermal conductivity, or approximately between 1.2-3.05 W/m·K ASTM C 182 at 800° C., more specifically the thermal conductivity may be between 1.3 and 2.5 W/m·K ASTM C 182 at 800° C., even more specifically between 1.5 and 2.4 W/m·K ASTM C 182 at 800° C.
A device according to any of the preceding claims, wherein the thermal insulation layer is a layer of a material that has a low thermal conductivity, or approximately between 0.1-0.5 W/m·K ASTM C 182 at 800° C., more specifically the thermal conductivity may be between 0.1 and 0.35 W/m·K ASTM C 182 at 800° C., even more specifically between 0.15 and 0.24 W/m·K ASTM C 182 at 800° C.
