specific Embodiment approach 2

[0021] Specific implementation mode two: combination figure 1 Describe this embodiment, each telescopic assembly described in this embodiment includes a spring connector 5, a spring 6 and a connecting sleeve 7, one end of the spring 6 is connected to a corresponding electrode assembly 1 through the spring connector 5; the other end of the spring 6 One end is connected to a corresponding intermediate contact 8 through a connection kit 7 .

[0022] With such arrangement, the telescopic assembly can enable the electrode to have a telescopic function as the burner damper switch moves, which is convenient for ignition.

[0023] Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0024] Specific implementation mode three: combination figure 1 Describe this embodiment, each electrode assembly 1 described in this embodiment includes an electrode 1-1 and an insulating ceramic sheath 1-2, the insulating ceramic sheath 1-2 is set on the electrode 1-1, and the ignition of the electrode 1-1 The end extends from the end of the insulating ceramic sheath 1-2.

[0025] In this way, an insulating ceramic sheath 1-2 is installed on each electrode to strengthen the insulation and enhance the oxidation resistance.

[0026] Other components are the same as those in the second embodiment in terms of connections.

specific Embodiment approach 4

[0027] Specific implementation mode four: combination figure 1 To illustrate this embodiment, an ignition device for increasing the service life of an oil-fired boiler described in this embodiment further includes a fixed platen 2, which is set in the middle of two insulating ceramic sheaths 1-2.

[0028] The pressure plate 2 is composed of the upper and lower halves of the stainless steel pressure plate. The upper pressure plate and the lower pressure plate are set opposite to each other, and are used to fix the insulating ceramic sheath outside the two electrode assemblies, and at the same time play a position-limiting role, and are also used to communicate with the burner damper. Snap connection on bezel.

[0029] Other compositions and connections are the same as those in the first, second or third embodiment.

Abstract

The invention discloses an ignition device for prolonging the service cycle of an oil-fired boiler, relates to an ignition device, and aims at meeting the use need, facilitating to maintenance for a boiler ignitor, and solving the problem of short service cycle of an oil-fired boiler. The ignition device for prolonging the service cycle of the oil-fired boiler comprises two electrode assemblies, ahigh-voltage junction box, two telescopic assemblies, two middle contacts and two rear contacts, wherein the two electrode assemblies are plugged into the high-voltage junction box in parallel; the two telescopic assemblies, the two middle contacts and the two rear contacts are sequentially installed in the high-voltage junction box from the left to the right; the right end of each electrode assembly is connected with the middle contacts through one telescopic assembly; and the middle contacts are connected with the rear contacts. According to the ignition device for prolonging the service cycle of the oil-fired boiler, the service cycle of the ignitor is prolonged, and then the service cycle of the boiler is prolonged, the cost is lowered, and the economic benefits are improved.

Description

technical field [0001] The invention relates to an ignition device, in particular to an ignition device for improving the service life of an oil-fired boiler. The invention belongs to the technical field of boiler ignition. Background technique [0002] Due to the low cost of heavy oil, oil-fired boilers generally use heavy oil as fuel. Use the igniter to ignite the fuel for boiler work. The igniter generally adopts a fixed igniter, and the ignition electrode assembly and the high-voltage junction box are fixedly installed on the boiler burner, which is used for starting and igniting the boiler under normal conditions. The ignition electrode assembly is fixed on the damper baffle of the boiler burner air distribution device, and the high-voltage junction box is fixed on the front shell of the boiler burner air distribution device. Since the ignition electrode assembly is installed facing the boiler furnace, it is a vulnerable part due to high temperature and needs to be re...
