Description

High-efficiency burner and electric flame stove Technical Field The utility model relates to an electric flame stove. Background The electric flame stove is also called as a plasma stove, and is a novel flame generation mode, an electric field with high frequency change is adopted, two electrodes generate an electric arc phenomenon under a certain voltage, the electric arc is a beam of high-temperature ionized gas, and the electric flame stove uses continuous electric arc as energy for heating a pot body. The utility model patent with the application number 202311369153.9 discloses a furnace end for rotating working medium jet flow, which comprises a cathode plate, a plurality of cathode flame spraying pipes which are arranged on the cathode plate and are of hollow structures, a plurality of insulating seats and a plurality of anode needles which are arranged on the insulating seats, wherein a plurality of air inlet holes are arranged at the bottoms of the insulating seats, and the air inlet holes are in inclined design and are used for manufacturing air fluid rotating in an electric arc generating space. However, in the above patent, the plasma moves to the outside of the flame tube rapidly with the air flow, and the electron density cannot be increased, which results in low efficiency, and even if a high power current is input, the energy input by the high power is difficult to be converted into the "high energy state" (the excited state and the dissociated state of the particles) of the plasma, but rather a large amount of loss is generated. Meanwhile, after the working gas of the furnace end enters the inside of the insulating seat, centrifugal rotary airflow is formed, and the airflow is rapidly carried away from the discharge area when passing through a strong electric field, so that the gas is not fully ionized, and the efficiency of electrode ionization of the working gas is low.
