Embodiment 1

[0078] "constitute"

[0079] figure 1 It is a schematic diagram showing the appearance of the evaporative burner 1 according to the first embodiment of the present invention viewed from the downstream side. figure 2 yes figure 1 The A-A line sectional view. In the following description, the upper side in the vertical direction ( figure 1 as well as figure 2 The upper side of the sheet of paper) is referred to as "upper", and the opposite side, that is, the lower side, is referred to as "lower". Additionally, toward figure 2 , let the left side be the "upstream side", and the opposite side, that is, the right side, be the "downstream side".

[0080]The evaporative burner 1 includes an outer casing 2 and an inner casing 3 disposed inside the outer casing 2 . The shapes of the outer casing 2 and the inner casing 3 are not particularly limited, and can be appropriately designed according to the application and usage environment of the evaporative burner 1 , for example. ...

Embodiment 2

[0144] As described above, according to the evaporative burner 1 of Embodiment 1 of the present invention, it is possible to simultaneously solve the first problem and the second problem, that is, the first problem is to supply air to the ignition device in an amount suitable for igniting fuel. The vicinity of the device, thereby improving the ignitability of the evaporative burner, and prolonging the life of the liquid core. The second problem is to avoid the difficulty of fuel penetration into the liquid core, and to improve the heat transfer from the ignition mechanism to the liquid core, thereby Improves ignitability of evaporative burners.

[0145] The evaporative burner 1 a of the second embodiment of the present invention described below aims to solve the third problem of reducing air shortage that causes incomplete combustion of fuel on the downstream side of the combustion chamber.

Embodiment 3

[0166] In the above-described evaporative burners 1 and 1a, except for a local bent portion, a promotion member having a planar (plate-like) shape as a whole is used. However, in a plate-shaped accelerator member, deformation (thermal deformation) of the accelerator member may occur due to a temperature change accompanying fuel combustion. Therefore, in Example 3 of the present invention, the rigidity (section modulus) of the accelerator member is increased, and thermal deformation of the accelerator member accompanying fuel combustion is reduced.

[0167] "structure"

[0168] Such as Figure 23 As shown, in the evaporative burner 1b according to the third embodiment of the present invention, the promotion member 50 is constituted by a plate-shaped member having a curved surface shape in which the central portion protrudes toward the upstream side. In addition, the impregnating member 48 is also constituted by a plate-shaped member having a curved surface shape in which a ce...

Abstract

Disclosed is an evaporative-type burner. An acceleration member (10) is disposed across a prescribed gap on an impregnation member (8) that is installed on the upstream end of a combustion chamber (30), an ignition device (22) and a first air supply port (24) are provided in an ignition space upstream from the acceleration member (10), and a second air supply port (28) is provided in a combustionspace downstream from the acceleration member (10). Fuel is supplied to the smooth surface of the impregnation member (8), and at least part of the ignition device (22) is accommodated in a recess (8c) or notch (32) formed in the impregnation member (8). A configuration is adopted such that the flow of air supplied to the combustion space from the second air supply port (28) increases further downstream. This improves ignition performance in the evaporative-type burner (1), and minimizes incomplete combustion of fuel on the downstream side of the combustion chamber (30).

Description

technical field [0001] This invention relates to evaporative burners. Background technique [0002] Conventionally, there is known an evaporative burner in which fuel is immersed in a liquid wick disposed at one end of the combustion chamber, and fuel vapor generated from the liquid wick is heated by a glow plug disposed near the liquid wick to ignite and burn. Such an evaporative burner is expected to be used, for example, as a heat source for regeneration of a diesel particulate filter (DPF) mounted on a vehicle using diesel fuel, and in devices for heating vehicles and houses. [0003] In addition, although the evaporative burner is provided with an air intake port for introducing air for burning fuel into the combustion chamber, the glow plug may be cooled by the introduced air and the ignitability of the evaporative burner may be reduced. . Therefore, it is proposed to provide a windproof member on the side of the glow plug opposite to the liquid core (that is, the ai...
