Description

The high combustion rate burner Electric spark ignitor

The utility model belongs to electric ignition device, is used for the Electric spark ignitor of the igniting of various combustion gas, fuel oil industrial furnace, particularly high combustion rate burner.

At present, the igniting of industrial heating furnace high pressure gas high combustion rate burner, automobile spark plug commonly used, because spark is little, eddy current not, the duration of ignition is long or can not use because of the tar bonding, often causes furnace explosion, and is dangerous.As Chinese patent CN20505400U " portable high energy ignition unit ", this device adopts rectification, energy storage, produces the pulse-triggered spark plug with flip flop equipment and gets angry, and is not suitable for the igniting of the industrial heating furnace of large-scale, high temperature, high combustion rate burner.

The purpose of this utility model provides a kind ofly to be used on large scale industry heating furnace high pressure gas high combustion rate burner, and igniting is fast, can produce the Electric spark ignitor of rotation spark and combustion gas eddy current.

The utility model high combustion rate burner Electric spark ignitor, comprise by front end being that negative pole urceolus, insulation attachment cap and the high pressure grafting positive contact of igniting chamber is connected as a body successively, it is characterized in that: be provided with the metal igniting pin of isolating in step tubular metal urceolus and the tubulose insulation attachment cap by the high-temperature insulation pipe, be positioned at and have a circle on the outer tube wall of igniting chamber igniting needle end part and touch annular distance (1), the other end of igniting pin connects the high pressure webge contact.

During use, with the high combustion rate burner Electric spark ignitor, insert in the high combustion rate burner fire hole, make the step place and the burner fire hole of urceolus tight-closed, low-pressure end by the button control high-tension transformer, positive pole after rectification connects the contact of high combustion rate burner Electric spark ignitor, the negative pole shell of meeting sb. at the airport, and promptly the urceolus with the high combustion rate burner Electric spark ignitor is connected.After the energising, between the igniting pin of igniting chamber and urceolus, produce rotation spark and combustion gas eddy current.

The utlity model has that spark is big, igniting is fast; Can produce rotation spark and combustion gas eddy current; Advantage such as safe and reliable.Be applicable to combustion gas, fuel oil, heating furnace, use in the electricity sparking of high combustion rate burner.

Below with reference to accompanying drawing the utility model is described in further detail.

Fig. 1 is the longitudinal sectional drawing of a kind of concrete structure of the utility model.

Negative pole urceolus of the present utility model (4) is the step metal tub, long 100mm, and internal diameter ∮ 7mm inserts inside, high combustion rate burner hole and is divided into 60mm, igniting chamber internal diameter ∮ 10mm wherein, long 25mm, external diameter 13mm.On urceolus (4) wall of the igniting chamber of urceolus (4), the circle that has a ∮ 7mm is touched annular distance (1), centre-to-centre spacing termination, hole 7mm.Tubulose insulation attachment cap (5) is wooden, pegs graft with urceolus (4), and connects with high-temperature flame-proof is gluing.Be installed with high-temperature insulation pipe (2) in the middle of urceolus (4) and the attachment cap (5), material is a quartz glass tube.Penetrate metal igniting pin (3) in the insulation tube (2), its material is the steel wire of ∮ 1mm.One end of igniting pin (3) is connected with high pressure webge contact (6).

Claims (1)

1, a kind of high combustion rate burner Electric spark ignitor, comprise by front end being that negative pole urceolus (4) the insulation attachment cap (5) of igniting chamber is connected successively with high pressure grafting positive contact (6) and is integral, it is characterized in that being provided with in step tubular metal urceolus (4) and the tubulose insulation attachment cap (5) the metal igniting pin (3) of isolating by high-temperature insulation pipe (2), be positioned at and have a circle on urceolus (4) wall of igniting chamber igniting pin (3) end and touch annular distance (1), the other end of igniting pin (3) connects high pressure webge contact (6).
