Abstract

Provides a technique for rapidly homogenizing ambient gas into desired components and uniformly increasing the temperature of ambient gas. The combustion device (500) has a combustion part (100) and an adjustment gas flow path part (200), the combustion part has a combustion space (10) and is provided with a combustible opening to the combustion space (10) and allowing a combustible gas to flow in A gas inflow port (30), an air inflow port (50) that opens into the combustion space (10) and allows air to flow in, and a combustion gas discharge port (70) that discharges the combustion gas to the outside, the adjustment gas flow path portion It has a regulated gas discharge port (150) that discharges the regulated gas adjusted to a desired composition to the outside, and is adjacent to the combustion gas discharge port (70) and faces the combustion gas opening just discharged from the combustion gas discharge port (70) .

Description

technical field [0001] The invention relates to a combustion device and a heating furnace using the same. Background technique [0002] When manufacturing various products, heat treatment is sometimes performed. In heat treatment, it is of course necessary to control the amount of heat applied to the object to be heated, and it is sometimes required to strictly control the composition of the ambient gas in which the object is placed during heating. For example, in the manufacture of ceramic products, a molded body formed of ceramic powder into a desired shape is first produced, and then the molded body is placed in a heating furnace for heat treatment (firing). [0003] Burners are sometimes used for temperature control in furnaces. As a burner used in a heating furnace, for example, a burner of a type (multi-quantity type) in which the mixing ratio of combustion gas and air is appropriately adjusted inside a cylindrical body to generate a flame has been proposed (for exam...
