TECHNICAL SOLUTIONS FOR BURNING OF THE DEPRESSED IONIZED GAS FUEL IN THE ELECTRIC FIELD
To improve the efficiency of gas equipment, the author proposes a technical solution for the device for forcing ionization of gas fuel. The principle of its operation is based on the use of the method of burning of the depleted ionized gas fuel in the electric field. The proposed method ensures maximum combustion of gas fuel, the reduction of heat losses for air heating, soot formation on the heat exchange surfaces, thermal resistance, as well as the completeness of chemical combustion.
The novelty of technical solution is the creation of the catalytic electric field by means of incorporating an ionizing device into the design of a gas stove that supplies the voltage of 7 kV to the electrodes with the current force of 2...3 mA. The additional electrification of gas fuel ensures the formation of Coulomb forces, intensifies the combustion, and the convection heat exchange increases due to the electroconvection.
The device design provides for the placement of electrodes at a distance of 50 mm from each other. The electrodes are powered from the voltage source (high-voltage transformer, through a rectifier). The fastening of the electrodes is performed using the ring porcelain insulators. Structural changes of the stove provide the increased temperature of the torch and the radiation power both in the visible and infrared range and in the ultraviolet. The additional electrolysis of the fuel mixture and the acceleration of its burning rate are achieved by the ionization.
The experimental studies carried out to determine the characteristics of the processes of gas fuel combustion (isobutane (CH3–CH(CH3)–CH3) – 72 %, butane (CH3–CH2–CH2–CH3) – 22 %, propane (С3Н8) – 6 %) in the electric field of the variable intensity allowed establishing that the constructional solution provides the increase in the temperature of the frying deck by 39 %, heat transfer – by 2 times, the efficiency factor – by 22 %, the reduction of carbon oxides – by 31...36 %, and the gas fuel consumption when cooking – by 26 %.
