Embodiment 1

[0034] In order to solve the problem of poor accuracy in detecting the flame of the ignition device in the prior art, this embodiment proposes an ignition device, a flame detection method, and a combustion system, as shown in the attached Figure 1-4 As shown, the ignition device 1 is applied in a combustion system, and the combustion system can be a conventional torch system or a conventional burner; The system provides a pilot flame to maintain the continuous combustion of the main flame in the combustion system.

[0035] For ease of description, the main flame of the combustion system is collectively referred to as "main flame", and the flame of the ignition device 1 is collectively referred to as "pilot flame".

[0036] For the ignition device 1, it is a hollow straight tubular structure, and its main body is marked as the outer tube 15. For the sake of illustration, part of the length of the pipe section is omitted in the drawings; the ignition device 1 is provided with a...

Embodiment 2

[0054] Considering that different fuels have different demands on the combustion environment, for the fuel gas that is easier to maintain combustion, the ignition device 1 can maintain the relevant structure of the first embodiment. For the fuel gas that is relatively difficult to maintain combustion, this embodiment further improves the ignition device 1 on the basis of Embodiment 1, specifically:

[0055] as attached image 3 As shown, the fuel pipe 3 includes a main fuel pipe 31 and a secondary fuel pipe 32. The feed end of the main fuel pipe 31 and the feed end of the secondary fuel pipe 32 all pass through the fixing seat 14, and are connected to the fuel main pipe 5 communicated; the discharge end of the main fuel pipe 31 and the discharge end of the auxiliary fuel pipe 32 are all arranged in the accommodating chamber 11; the distance between the discharge end of the main fuel pipe 31 and the fire outlet 12 is denoted as K', The distance between the discharge end of the...

Abstract

The invention provides an ignition device, a flame detection method and a combustion system. The ignition device is applied to the combustion system. The ignition device is internally provided with a containing cavity and comprises a fuel pipe, an ignition rod and a flame detection device, wherein at least part of structures of the fuel pipe, the ignition rod and the flame detection device are arranged in the containing cavity, and the flame detection device comprises an ion detection module and / or an electrical temperature measurement module. The ignition flame is detected through the ion detection module and / or the electrical temperature measurement module, so that the operation condition of the ignition device is detected in real time, and the accuracy of flame detection is improved.

Description

technical field [0001] The invention relates to the technical field of flame detection, in particular to a flame detection device, an ignition device, a flame detection method and a combustion system. Background technique [0002] In industrial combustion systems, such as torch systems, burners, etc., it is often necessary to set ignition devices inside the system, such as lights, igniters and other devices. [0003] According to the actual application and operation of the combustion system, the ignition performance of the ignition device must meet the following requirements: 1. High ignition success rate; 2. Stable flame combustion; 3. High temperature resistance and long service life. Among them, for the combustion system, the flame stability of the ignition device is particularly important; however, the maintenance of the flame is a dynamic process, which is easily affected by factors such as fuel, supporting gas and the outside world, and it is easy for the flame of the ...
