专利汇可以提供Heat accumulator专利检索，专利查询，专利分析的服务。并且In combination with a heat accumulating machine or oven a heat accumulator which comprises a eutectic mixture of LiF and fluoride having a melting point of less than 850*C of the group constituted by sodium fluoride and/or magnesium fluoride. The mixture may additionally comprise potassium fluoride and/or calcium fluoride. The heat accumulator is suitable for supplying thermal energy to a hot-gas engine and for use in heat accumulating ovens.，下面是Heat accumulator专利的具体信息内容。
1. In combination a heat accumulator comprising a reservoir which contains an inorganic material having a melting point of less than 850* and wherein the inorganic material consists mainly of a eutectic mixture of lithium fluoride and at least one fluoride selected from the group consisting of sodium fluoride, potassium fluoride, calcium fluoride and magnesium fluoride, potassium fluoride or calcium fluoride being present only in the presence of both sodium fluoride and lithium fluoride or both magnesium fluoride and lithium fluoride, the maximum quantity of potassium fluoride being less than 30 mol percent and the maximum quantity of calcium fluoride being less than 40 mol percent, a hot gas engine having a heater which receives thermal energy from said material, a burner in which is burned fuel in combustion gas to produce thermal energy, duct means for flowing said material (a) through said burner for receiving thermal energy therefrom, (b) to and through said heat accumulator, (c) to and through said heater, and back to said burner, and pump means for urging said material to flow through said duct means.
2. A hot gas engine having a heater in combination with a heat supply for said engine comprising a burner in which is burned fuel in combustion gas to produce thermal energy, means for introducing said fuel and gas thereto, a heat accumulator comprising a reservoir which contains an inorganic material having a melting point of less than 850* and wherein the inorganic material consists mainly of a eutectic mixture of lithium fluoride and at least one fluoride selected from the group consisting of sodium fluoride, potassium fluoride, calcium fluoride and magnesium fluoride, potassium fluoride or calcium fluoride being present only in the presence of both sodium fluoride and lithium fluoride or both magnesium fluoride and lithium fluoride, the maximum quantity of potassium fluoride being less than 30 mol percent and the maximum quantity of calcium fluoride being less than 40 mol percent, duct means for flowing said material successively and cnotinuously through said burner, heat accumulator, and heater, and pump means for causing said material to flow through said duct means.
3. Apparatus according to claim 2, wherein the inorganic material consists of a eutectic mixture of lithium fluoride and sodium fluoride.
4. Apparatus according to claim 2, wherein the inorganic material consists of a eutectic mixture of lithium fluoride and magnesium fluoride.
5. Apparatus according to claim 2, wherein the inorganic material consists of a eutectic mixture of lithium fluoride, sodium fluoride and calcium fluoride.
6. Apparatus according to claim 2, wherein the inorganic material consists of a eutectic mixture of lithium fluoride, sodium fluoride and magnesium fluoride.
7. Apparatus according to claim 2, wherein the inorganic material consists of a eutectic mixture of lithium fluoride, magnesium fluoride and potassium fluoride.
8. In a heat accumulating oven a heat accumulator comprising a reservoir which contains an inorganic material having a melting point of less than 850* and wherein the inorganic material consists mainly of a eutectic mixture of lithium fluoride and at least one fluoride selected from the group consisting of sodium fluoride, potassium fluoride, calcium fluoride and magnesium fluoride, potassium fluoride or calcium fluoride being present only in the presence of both sodium fluoride and lithium fluoride or both magnesium fluoride and lithium fluoride, the maximum quantity of potassium fluoride being less than 30 mol percent and the maximum quantity of calcium fluoride being less than 40 mol percent, said accumulator being the source of thermal energy for said oven, and means for transferring said thermal energy from said accumulator to said oven.
