Embodiment 1

[0021] As shown in Figure 1.

[0022] A double gas source hypoxia protective ignition device for a gas heater, comprising a mounting frame 1, on which a thermocouple 2, a discharge electrode 3, a high calorific value gas ignition nozzle 4, and a low calorific value gas ignition nozzle 5 are installed , the high calorific value gas ignition nozzle 4 and the low calorific value gas ignition nozzle 5 are installed obliquely on the installation frame 1, and the thermocouple 2 is installed between the two, and its top is located at the high calorific value gas ignition nozzle 4 and the low calorific value gas ignition nozzle Near the intersection of the axes of 5, the discharge electrode 3 is installed on the installation frame 1 together with the thermocouple 2, and its discharge end should be located above the thermocouple 2.

[0023] During specific implementation, the discharge electrode 3 can be installed on the mounting frame 1 in addition to being installed on the mounting f...

Embodiment 2

[0025] as shown in picture 2.

[0026] A double gas source anoxic protective ignition device for a gas heater, comprising a mounting frame 1 on which a thermocouple 2, a discharge electrode 3, a high calorific value gas ignition nozzle 4, a low calorific value gas ignition nozzle 5, and a high calorific value gas ignition nozzle 5 are installed. The gas ignition nozzle 4 and the low calorific value gas ignition nozzle 5 are installed obliquely on the mounting frame 1, and the thermocouple 2 is installed between them, and its top is located on the axis of the high calorific value gas ignition nozzle 4 and the low calorific value gas ignition nozzle 5 Near the intersection point, the number of discharge electrodes 3 is two, the discharge end of one discharge electrode 3 is located above the high calorific value gas ignition nozzle 4, and the discharge end of the other discharge electrode 3 is located above the low calorific value gas ignition nozzle 5. They are all fixedly insta...

Embodiment 3

[0028] As shown in Figure 3.

[0029] A double gas source hypoxia protective ignition device for a gas heater, comprising a mounting frame 1 on which a thermocouple 2, a discharge electrode 3, a high calorific value gas ignition nozzle 4, and a low calorific value gas ignition nozzle 5 are installed. High value gas ignition nozzle 4 and low calorific value gas ignition nozzle 5 are installed in parallel on the mounting frame 1, and the outlets of high calorific value gas ignition nozzle 4 and low calorific value gas ignition nozzle 5 are equipped with deflectors 6, deflectors 6 is respectively provided with an ignition injection hole 7 and a gas injection hole 8 for hypoxia protection. The thermocouple 2 is installed between the two injection holes 8, and its top is not lower than the horizontal position of the two injection holes 8. The discharge terminal should be located above the thermocouple 2.

[0030] The discharge electrode 3 can be installed directly on the mounting ...

Abstract

The invention relates to a double gas source protective portfire, which can solve the problem that one fuel gas heater needs two fuel gases, but there is not right protective portfire. It comprises a mounting support (1), while said mounting support (1) is mounted with a thermal coupler (2), a discharge electrode (3), a high thermal valve fuel gas ignite jet (4), and a low thermal valve fuel gas ignite jet (5). Wherein, the thermal coupler (5) is mounted between the high thermal valve fuel gas ignite jet (4) and the low thermal valve fuel gas ignite jet (5). It has simple structure and high reliability.

Description

technical field [0001] The invention relates to a gas heater component, in particular to a dual gas source gas heater component, in particular to a dual gas source anoxic protective ignition device. Background technique [0002] At present, with the continuous improvement of transportation technology and the increasing shortage of oil resources, natural gas, biogas and other low calorific value gases have gradually entered people's daily life, and the single energy source in cities is being gradually broken by the multi-energy supply system. At the same time, it has become possible to connect the gas supply pipelines of coal gas, natural gas, liquefied petroleum gas, biogas and other energy sources. People can choose the appropriate gas to use according to market price changes and gas supply conditions. Taking the gas heater as an example, in the past, it was a single structure dedicated to liquefied petroleum gas or natural gas. Due to the different calorific values ​​of va...
