Description

Technical Field

[0001] The present invention relates to the technical field of oil supply systems, in particular to a heating ignition method. Background Art

[0002] The ignition method of traditional fuel supply systems mainly relies on spark plugs or direct ignition. This method has low ignition efficiency, especially in low-temperature environments. It is difficult for the fuel to fully vaporize, resulting in incomplete combustion and energy utilization of less than 85%. Secondly, unburned fuel not only wastes energy, but also produces a large amount of harmful emissions, exacerbating environmental pollution. When in use, it is necessary to equip it with complex ignition circuits and high-voltage components, which not only increases manufacturing costs but also poses safety hazards due to the exposure of high-temperature components. Inadequate thermal insulation design further leads to heat loss, and the system thermal efficiency is generally less than 75%. These problems are more prominent in applications with high-viscosity fuels such as heavy oil, and often lead to pipeline blockage or unstable combustion due to insufficient preheating. Summary of the Invention

[0003] In view of this, the present invention proposes a heating ignition method to solve the problems existing in the technical background. The specific contents include the following:

[0004] A heat ignition method includes a heating source, which utilizes a heating element and is installed at the outlet of a fuel supply device to rapidly heat the fuel to an ignition temperature. The fuel supply device includes a fuel pump and a delivery pipeline, and the fuel pump delivers fuel from a storage tank to the heating source. The fuel is delivered to the heating source through the fuel supply device, where it is heated to its ignition temperature and ignited. This heat ignition method ensures more complete fuel combustion, reduces emissions of unburned fuel, and lowers energy consumption.

[0005] In some embodiments of the present invention, a heat insulation structure is provided around the heating source to reduce heat loss and improve thermal efficiency.

[0006] In some embodiments of the present invention, the fuel supply device is provided with a control device, which includes a sensor and a controller. The temperature of the heating source is monitored and adjusted in real time by the temperature sensor and the controller to ensure a stable ignition process.

[0007] In some embodiments of the present invention, the structure of the heating source is designed as a multi-section spiral flow channel to extend the residence time of the fuel in the high temperature zone and ensure sufficient heating.

[0008] The above technical solution has the following beneficial effects:

[0009] In the present invention, fuel is delivered to a heating source via a fuel supply device, which heats the fuel to its ignition temperature, igniting a flame. Heating the fuel to the ignition temperature via the heating source enables efficient combustion, resulting in a simple structure, low manufacturing cost, excellent thermal insulation, efficient combustion, and energy conservation. The present invention directly raises the fuel to its auto-ignition temperature by heating, achieving improved ignition. This improves combustion efficiency, significantly increases fuel utilization, and reduces CO emissions. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic diagram of a heating ignition method of the present invention. DETAILED DESCRIPTION

[0011] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0012] Example 1, see Figure 1 A heat ignition method is shown, comprising a heating source, employing a heating element, installed at the outlet of a fuel supply device, enabling rapid heating of the fuel to an ignition temperature. The fuel supply device includes a fuel pump and a delivery pipeline, with the fuel pump delivering fuel from a storage tank to the heating source. The fuel is then delivered to the heating source via the fuel supply device, where it is heated to its ignition temperature, igniting a flame. This heat ignition method ensures more complete fuel combustion, reduces unburned fuel emissions, and lowers energy consumption.

[0013] The heating ignition method of the present invention is adaptable to a variety of fuel types, including liquid fuels such as diesel, kerosene, and biofuels. Based on the auto-ignition temperature characteristics of different fuels, generally about 200°C for diesel and about 220°C for kerosene, the heating element power and temperature control parameters of the heating source need to be dynamically adjusted. For high-viscosity fuels, a preheating module can be integrated into the delivery pipeline to improve fluidity through graded heating and avoid blockage. In addition, the fuel supply device needs to be equipped with a filtration system to prevent impurities from carbonizing and depositing during the heating process, which would affect the heat transfer efficiency.

[0014] The heating source is designed with a multi-stage spiral flow channel, which prolongs the fuel's residence time in the high-temperature zone and ensures sufficient heating. The insulation structure utilizes a nano-aerogel composite material with a thermal conductivity of less than 0.02 W / (m·K). Combined with a double-layer stainless steel shell, this creates a vacuum insulation chamber, reducing heat loss to less than 5%. The control unit integrates multi-sensor fusion technology: a temperature sensor, flow meter, and flame ionization detection probe form a closed-loop feedback system. The controller uses an algorithm to calculate the required fuel calorific value in real time, dynamically matching heating power with pump flow. For example, if insufficient flame intensity is detected, the heating temperature is automatically increased by 10% to 15% and the fuel supply is increased by 5%. The safety protection module, which includes a fuse, a pressure relief valve, and an emergency shut-off switch, immediately shuts down the system and issues an alarm if overtemperature, abnormal pipeline pressure, or ignition failure is detected.

[0015] Example 2, based on Example 1, utilizes a heating element as the heating source. This element is installed at the outlet of the fuel supply device to ensure that the fuel is quickly heated to the ignition temperature. The fuel supply device includes a fuel pump and a delivery pipeline. The fuel pump transports the fuel from the storage tank to the heating source. The insulation structure uses high-temperature resistant material to encase the heating source, reducing heat loss to the surrounding environment. The control device uses a temperature sensor and controller to monitor and adjust the temperature of the heating source in real time to ensure a stable ignition process.

[0016] In practice, using diesel as an example, fuel is pumped to a heating source, which heats the diesel to approximately 200°C (diesel's auto-ignition temperature), igniting the flame. The control system dynamically adjusts the heating power and fuel supply based on the combustion state to ensure continuous and sufficient combustion.

[0017] In the present invention, fuel is delivered to a heating source via a fuel supply device, which heats the fuel to its ignition temperature, igniting a flame. Heating the fuel to the ignition temperature via the heating source enables efficient combustion, resulting in a simple structure, low manufacturing cost, excellent thermal insulation, efficient combustion, and energy conservation. The present invention directly raises the fuel to its auto-ignition temperature by heating, achieving improved ignition. This improves combustion efficiency, significantly increases fuel utilization, and reduces CO emissions.

[0018] The above describes the basic principles and main features of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the invention to be protected.
