Abstract
A radiation heating apparatus comprising a heating zone, a zone to be heated, a gas non-permeable boundary member defining the boundary between the two zones, and a porous radiator member provided in the heating zone, wherein a high-temperature gas is formed in, or introduced into, the heating zone and discharged at least through the porous radiator member, and the zone to be heated is heated through the gas non-permeable boundary member.
Claims34
A radiation heating apparatus comprising within a housing therefor,
- (a) a first heating zone,
- (b) a second zone to be heated through a gas non-permeable boundary member,
- (c) said gas non-permeable boundary member separating and defining the boundary between the two zones and being made of a material substantially optically non-transparent to radiation energy,
- (d) at least one means selected from means for generating or introducing a high-temperature gas, said means being positioned in a sub-zone within the heating zone adjacent to the boundary member,
- (e) a porous radiator member in the heating zone, said porous radiator member having pores through which the high-temperature gas formed in, or introduced into the sub-zone is discharged, and
- (f) a porous heat-receiving member in the zone to be heated, whereby said porous heat-receiving member is heated through the gas non-permeable boundary member.
A radiation heating apparatus comprising a housing member;
- a first zone located within said housing member, said first zone including means for receiving or generating a high-temperature gas;
- a second zone located within said housing member, said second zone including means for receiving therein a substance to be heated by heat provided by said high-temperature gas;
- a gas non-permeable boundary member in contact with, and separating from each other, said first and second zones and being made of a material substantially optically non-transparent to radiation energy;
- a porous radiator member located in said first zone and positioned therein in heat-flow relationship to said boundary member;
- and
- means for flowing the high-temperature gas through the porous radiator member in a direction generally away from said boundary member;
- whereby, in operation, high-temperature gas flows through said porous radiator member to raise the temperature thereof and heat radiated from said heated porous radiator member contacts said gas non-permeable boundary member and said heat is in turn radiated from and/or transmitted through said boundary member into said second zone to thereby heat said substance in said second zone.
A method for raising the temperature of a substance in a temperature raising zone of radiation heating apparatus by exposing the substance to radiant heat energy passing through or from a gas non-permeable boundary member which separates the temperature raising zone of the apparatus from a heating zone of the apparatus said boundary member being made of a material substantially optically non-transparent to radiation energy, wherein the heating zone includes therein a porous radiator member, said method comprising,
- generating a high-temperature gas;
- passing the high-temperature gas through the porous radiator member in a direction away from the gas non-permeable boundary member whereby the porous radiator member is brought to an elevated temperature to generate radiant energy;
- allowing the radiant energy generated by the porous radiator member to be absorbed by and/or transmitted through the gas non-permeable boundary member into the temperature raising zone whereby the temperature of the substance to be heated is raised by the heat energy transmitted through or by the boundary member.
