Atomization ignition method and device for liquid fuel

Abstract

The invention discloses an atomization ignition method and device for liquid fuel. The ignition method comprises the following steps: presetting ignition liquid fuel amount; starting an igniter to preheat; enabling the liquid fuel with preset amount to enter a T-junction from a first port of the T-junction; meanwhile, starting an air blower to enable the air blower to operate at a low wind speed and supply air to the T-junction from a second port of the T-junction through an air-splitting pipe; atomization ejecting the liquid fuel to a combustor from an oil nozzle communicated with the last port of the T-junction; enabling the igniter to ignite the atomization fuel entering the combustor. The ignition device comprises an ignition switch, a speed regulator, the air blower, a main air pipe, an oil conveying pipe, the air-splitting pipe, a main oil path, an ignition oil path, the igniter, an ignition needle, an oil conveying T-junction, an oil gas mixture atomization T-junction and the combustor. According to the method and device, provided by the invention, the operation is convenient, the success rate of one-time ignition is high, and prominent substantive characteristic and remarkable improvement are realized.

Description

technical field [0001] The invention relates to a pulse electronic ignition device and an ignition method for civil stoves, in particular to a liquid fuel atomization pulse electronic ignition device and an ignition method. Background technique [0002] In the field of daily civilian stove heating, liquid fuels such as diesel and alcohol-based fuels are widely used, especially in civilian applications, these liquid fuels do not have special pressure atomization devices, and generally flow into the burner through the self-weight pressure generated by the height difference. The electronic ignition device is used to generate a high-voltage arc, which directly ignites the liquid fuel flowing into the burner. When igniting, the damper is closed to prevent the air from blowing out the flame. Since the liquid fuel is not atomized and properly proportioned with air, the ignition success rate is low at the beginning of a cold stove. [0003] Excessive wind force or not properly prop...

AI Technical Summary

Problems solved by technology

Because the liquid fuel is not atomized and properly proportioned with air, the ignition success rate is low at the beginning of a cold stove

[0003] Excessive wind or failure to properly mix the liquid fuel with air is the main factor leading to ignition failure in the prior art

However, if the oil supply and the opening of the air valve on the main air pipe are adjusted at the same time to reduce the air volume and cooperate with the ignition, the operation and control will be difficult, and the fire will not ignite or the ignited flame will be blown out by the excessive air volume.

There is also a way of using a pressure atomizer for atomization and ignition. The structure of the pressure atomizer is complicated and the price is relatively expensive, which limits its application in civilian stoves.
