Problems solved by technology

Although this method cancels the high-voltage pulse igniter and the discharge electrode, which simplifies the system configuration to a certain extent, the existing problems are: it does not have the intelligent control function, and the power-on time of the heating wire is fixed when igniting. There are limitations in use; the heating wire is used as a heating element, the mechanical strength is not high, it is easy to oxidize and break, and the service life is not long
[0004] In short, there is no method in the prior art to realize automatic ignition and detection of oil burners through intelligent control

Embodiment approach

[0018] figure 2 It is the first embodiment of the present invention, which is applied to the premixed burner. The energy storage body 2 is installed in the thermal stability chamber 3 and is about 5-10mm away from the edge of the fin 6 on the evaporator 5. The high temperature area of ​​the energy storage body 2 It is roughly on the same level as the fins 6; the temperature sensor 7 is installed in the pre-mixing chamber 1 to detect the ambient temperature of the ignition. see figure 1 , the voltage detection will transmit the power supply voltage value and the temperature sensor to the ignition environment temperature value to the controller, and the computer in the controller will use the mathematical model or interpolation method to calculate and set the best warm-up time for the energy storage body 2, when the energy storage body 2 When the temperature reaches above 1000°C, the controller enters the ignition program, the air enters the thermal stability chamber 3 along t...

Abstract

The invention relates to an igniting method of an oil burner, comprising the following steps of: detecting flame temperature, voltage, environmental temperature and supply voltage by adopting an intelligent controller through arrangement; calculating detected data by using a mathematical model or an interpolation method through a computer; automatically setting optimal igniting time; when the temperature of an energy storage body reaches above 1000 DEG C, detecting a flame condition by setting flame detection after the controller enters an igniting program; controlling the optimal igniting time; using the energy storage body as an igniting heat source, and adopting electric power to store heat, wherein the power range is 10-100W, the supplied power is alternating current or direct currentwith voltage of 6-240V, and the highest temperature of 1000-1500 DEG C can be achieved in 5 seconds; and detecting flame by adopting a photoconducting device or an ion detection device. The inventioncan control the optimal igniting time and realize the automatic, convenient, quick, accurate and reliable ignition of the burner.

Description

technical field [0001] The invention belongs to the technical field of automatic ignition of oil burners. Background technique [0002] Due to the characteristics of the liquid fuel itself, the ignition method of the oil burner using liquid as the fuel, in the past, the fuel is heated and preheated and then artificially ignited by an open flame, or the fuel is ignited by high-voltage pulse after atomization and vaporization. The artificial open flame ignition method after preheating is laborious and time-consuming; the high-voltage pulse ignition method after atomization and vaporization needs to be equipped with a high-voltage pulse igniter or power transformer, discharge electrode, etc. in the device, and the device is complicated; at the same time, the high-voltage pulse igniter itself is a source of interference , the generated electromagnetic waves affect system stability and pollute the environment. [0003] Chinese patent 200720027133.3 discloses an electrodeless ign...
