Abstract: An ignition device that ignites a mixture including an oxidizer and fuel includes a heating element (1) that has a heat generation region (1a) generating formerly heat to a temperature above the ignition temperature of the mixture (Y) at a tip projected downward from an installation unit (100), a fuel holding unit (2) that encloses the heat generation region (1a), in which the heat generation region (1a) is installed inside thereof and has a through hole (2a) opened to an upper part thereof, and a surrounding wall (3) that forms a space (R) connected to the upper part of the through hole (2a) and has a flame ejection opening (3a) opened from the space (R) to the outside. According to the ignition device, an ignitability of the ignition device can be improved.

Abstract: This burner apparatus (S1) includes: an ignition system (7) including a heating portion (7a, 7c) which heats air-fuel mixture to its ignition temperature or more; and a windbreak device (10) placed around the heating portion (7a, 7c) apart from the heating portion (7a, 7c), and configured to reduce a flow speed of fluid (X) which is supplied to the heating portion (7a, 7c). According to the burner apparatus (S1), it is possible to improve the ignition performance of the ignition system, and to also generate high-temperature gas stably.

Abstract: Disclosed is a burner device that includes a partition member which air-permeably partitions an ignition region for igniting a mixture gas and a flame retaining region for maintaining the combustion of the mixture gas, and also adjusts the flow speed of the mixture gas supplied from the ignition region to the flame retaining region, the partition member including a protrusion portion that protrudes into an oxidant flow passage and stops a part of the oxidant flowing through the oxidant flow passage to guide the oxidant into a take-in passage region.

Abstract: The present invention is a burner apparatus (S1, S2, S3, S4) that combusts air-fuel mixture (Y) of an oxidizing agent and fuel. This burner apparatus (S1, S2, S3, S4) includes a partitioning component (8) that separates an ignition chamber (R2) where the air-fuel mixture (Y) is ignited and a combustion holding chamber (R3) where the combustion of the air-fuel mixture (Y) is maintained such that the air-fuel mixture (Y) is able to pass between them, wherein the partitioning component (8) adjusts the flow rate of the air-fuel mixture (Y) that is supplied from the ignition chamber (R2) to the combustion holding chamber (R3).

Abstract: A burner device (S1) that burns a mixture gas of an oxidant and a fuel includes a partition member (8) which air-permeably partitions an ignition region (R2) for igniting the mixture gas (Y) and a flame retaining region (R3) for maintaining the combustion of the mixture gas (Y), and which also adjusts the flow speed of the mixture gas (Y) supplied from the ignition region (R2) to the flame retaining region (R3), in which the partition member (8) includes a protrusion portion (8a1) that protrudes into an oxidant flow passage (1) and that stops a part of the oxidant flowing through the oxidant flow passage (1) to guide it into a take-in passage region (R1). According to the burner device (S1), with a sufficient amount of oxidant being supplied to a combustion region, it is possible to stabilize a combustion state of the mixture gas and, moreover, to stably produce a high-temperature gas.

Abstract: A cooling passage is formed to have a helical configuration so that a flow rate of a cooling medium supplied to the cooling passage is controlled to be in an optimum cooling region. Accordingly, the contact surface area and the cooling volume of cooling water are decreased respectively. Further, it is possible to stably obtain an optimum casting quality with ease.
