Description

The utility model relates to a power system, mainly to devices for igniting gas and liquid fuel burners of combustion devices of hot water and steam boilers.

Known ignition devices of burners (RF patents No. 2169885 dated June 27, 2001; 2107226 dated March 20, 1998, No. 53411 dated May 10, 2006) containing a cylindrical burner housing c and an ignition element.

The closest analogue is the ignition device of the burner (RF patent No. 135774, dated December 20, 2013), containing a cylindrical burner body with a lateral gas mixture supply, at one end of which a high-voltage unit is rigidly fixed, as well as an ionization flame control sensor and a spark plug .

The disadvantage of this device is the instability of the ignition of the gas mixture due to the low reliability of the flame control in the furnace space, leading to a decrease in the reliability and safety of the ignition device.

The objective of the utility model is to create an ignition device, a burner that provides increased reliability and safety of the ignition device, as well as the possibility of using it for any type of furnace devices and any type of boilers.

The technical result is achieved by the fact that in the ignition device of the burner, which includes a cylindrical body with a side supply of the gas mixture, at one end of which a high-voltage unit is rigidly fixed, and also containing an ionization flame control sensor and a spark plug, a disk with nozzles located around placed eccentrically, a spark plug connected electrically to the high-voltage unit through a hollow tube mounted in the cavity of the housing, parallel to which there is an ion tube a flame control sensor, one end of which through the insulator is placed in the high-voltage unit, and the other end, which is the ionization flame control sensor, is placed through the insulator in the disk and protrudes beyond the surface of the disk, the tube cavity of the ionization flame control sensor through the side hole passing through the insulator in the high-voltage unit and the housing are in communication with the surrounding air.

The proposed design of the ignition device of the burner provides stable ignition by increasing the reliability of flame control in the furnace space.

The ignition device is illustrated by drawings:

In FIG. 1 shows a longitudinal section through an ignition device.

In FIG. 2 shows a left side view of the end face of the ignition device;

The ignition device comprises a cylindrical housing 1 with a side fitting for supplying the gas mixture 2, a high-voltage unit 4 is rigidly fixed at one end 3 of the cylindrical housing 1, a disk 6 is installed at the other end 5 of the cylindrical housing 1 with nozzles 7 arranged around an eccentric disk 6, candles ignition 8, electrically connected to the high-voltage unit 4 through a hollow tube 9 installed in the cavity 10 of the cylindrical housing 1, parallel to which is located the tube 11 of the ionization flame control sensor, one The EC 12 which through the insulator 13 is placed in the high-voltage block 4, and its other end 14 is the flame control ionization sensor itself, is placed through the insulator 15 in the disk 6 and protrudes beyond the outer surface 16 of the disk 6, the inner cavity 17 of the tube 11 of the ionization flame control sensor through a lateral hole 18, passing through an insulator 13 in the high-voltage unit 4 and the housing 1, is connected to the surrounding air.

The ignition device of the burner operates as follows.

Gas is supplied to the cylindrical housing 1 of the ignition device through the gas mixture supply nozzle 2, which is directed through the cavity 10 of the housing 1 to the nozzles 7 of the disk 6, on the outer surface 16 of which comes into contact with the air of the combustion device (not shown), and where the gas is ignited mixtures from the spark plug 8. An electric discharge to the spark plug 8 is supplied through the hollow tube 9 from the high-voltage block 4, which is rigidly fixed to the end face 3 of the housing 1. In contact with the flame of the end 14 of the ionization sensor tube 11, an electric The tertiary signal through the tube 11 enters its other end 12, which, through the insulator 13 in the high-voltage unit 4, is electrically connected to the flame control unit (not shown). Cooling of the ionization flame sensor - the end 14 of the tube 11 occurs with external ambient air entering the cavity 17 of the tube 11 through the side hole 18 made through the insulator 13 and the housing 1 at its end 3.

The inventive ignition device is reliable and safe to operate.

The claimed technical solution meets the criterion of "novelty", as from the well-known and publicly available sources of information have not identified a similar technical solution.

The claimed technical solution meets the criterion of "industrial applicability", as it can be made from known materials and by known methods.
