Abstract

The present invention addresses the problem of providing a heating furnace that sufficiently exhibits the microwave effect produced by microwave heating and allows economical heating taking advantage of the characteristics of each heating method. The provided microwave composite heating furnace (1) is equipped with: a housing (10); a heating container (11) for accommodating and heating an object to be heated; a heating means (12) for heating the heating container (11) from the outside; a microwave irradiation device (13); a to-be-heated object supplying device (14) that supplies the object to be heated to the inside of the heating container (11); a gas introducing means (15) for introducing gas into the heating container (11); and a gas recovery means (16) for recovering the gas generated when heating the object to be heated. The heating container (11) comprises a material that has high electrical conductivity so as to reflect microwaves and confine the microwaves inside and that has high heat resistance so as not to react with the heated object, thereby confining microwaves irradiated into the heating container (11) not through the outer wall of the heating container, and allowing an improvement in electromagnetic field density.

Description

technical field [0001] The present invention relates to a microwave composite heating furnace for heating an object to be heated by using a combination of microwaves and external heating such as a burner. Background technique [0002] It has been known since the 1980s that high power microwaves are emitted onto heated objects to heat them in order to provide, for example: [0003] (1) lower reaction temperature; [0004] (2) Shorter reaction time; [0005] (3) High purity material is produced (reaction selectivity). [0006] These properties are different from those chemical and physical properties obtained by conventional heating by flame or high temperature gas. These properties are known as the "microwave effect", which is caused by the direct action of microwave electromagnetic energy on the molecular structure of a substance before the electromagnetic energy is released as heat. There have been many attempts in many fields to apply this effect. [0007] like Figur...
