Abstract
Abstract A heater system comprising a reaction vessel having a liquid metal mixture and a container of oxidant communicating therewith via a regulating valve. The oxidant reacts with the metal melt exothermically producing solid and/or liquid reaction products. The system furthermore comprises a spare container filled with the same metal mixture, this spare container being in heat contact with the reaction vessel and in communication with said vessel through a supply duct and removal duct; pumping means are present for maintaining a continuous liquid flow from the reaction vessel to the spare container, all this in such manner that the formed reaction products settle in the spare container.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
29 words
A heater system according to claim 1, wherein the heat source means for the spare container comprises a portion of said vessel in heat exchanging relationship with the container.
Claim 2
Dependent Claim
25 words
A heater system according to claim 2 wherein the heat source formed by the reaction vessel, comprises heat transmitting wall incorporated in the spare container.
Claim 3
Dependent Claim
66 words
A heater system according to claim 1 wherein the reaction vessel is constructed as a circulating channel having locations at different pressures, the pumping means is incorporated therein with the liquid outlet duct and the liquid supply duct communicating respectively (i) with said places of different pressures in the channel, and (ii) with the outlet side of the pump and the suction side of the pump.
Claim 4
Dependent Claim
104 words
A heater system according to claim 1, wherein the spare container at room temperature is partly filled with reaction material and at the operating temperature said container is substantially entirely filled due to thermal expansion, the space above the material in the spare container containing a gas inert to the material, the system further comprising means for maintaining said inert gas at a selected pressure, the supply duct opening being at a level in the spare container which is situated only slightly below the liquid level at the operating temperature, and sealing means for closing the outlet duct until the operating temperature is reached.
Claim 5
Dependent Claim
47 words
A heater system according to claim 3 wherein the outlet duct is situated at substantially the same level as the supply duct in the spare container, its orifice being closed by a plate of a material which, shortly prior to reaching the operating temperature, melts or dissolves.
Claim 6
Dependent Claim
28 words
A heater system according to claim 1 wherein the spare container is divided into compartments by partitions which extend from the bottom to slightly below the liquid level.
