Kerosene cutter: operating principle and technical characteristics

Kerosene cutter It's designed for cutting low-carbon steels and uses liquid fuel—kerosene, gasoline, or diesel—instead of combustible gas. It differs slightly from an oxygen cutting torch in some respects, but the operating principle remains the same. Kerosene cutter It can be heated or unheated and has two nozzles (internal and external). When the kerosene is preheated and its vapors enter the asbestos braid of the evaporator, located in the mixing chamber, there is a heating nozzle. In the mixing chamber, the kerosene vapors are mixed with oxygen, after which they enter the cutting head, where one part of the mixture is in the heating nozzle, and the oxygen is released through the central channel of the cutting head. Oxygen enters kerosene cutter Kerosene is also supplied under pressure from a special tank through a hose through a fitting on the cutter handle. Passing through a tee, the kerosene vapor mixes with oxygen in a mixing chamber and then exits through the outer nozzle.

Kerosene metal cutters Two types are used: atomizing and vaporizing. Spray torches have a special atomizing device through which the liquid fuel is atomized and then fed into the nozzle, where it evaporates. The vaporizing type of torch has an asbestos-lined vaporization chamber. When kerosene enters this chamber, an additional flame vaporizes the liquid kerosene, converting it into kerosene vapor.

Kerosene cutter without heating, Spray type systems have some advantages:

• the weight of the cutter is almost half lighter;
• does not have asbestos winding, which allows servicing a kerosene cutter;
• there is no heating flame, so the cutter does not overheat during operation;
• can operate at temperatures of 40⁰From the cold with a special mouthpiece;
• has high resistance to flame backfire.

Kerosene cutter without heating - This new generation of kerosene cutting torches has a 20-second burn-in time and complete combustion, allowing for efficient fuel use. It features quick disassembly, easy access to parts and components, and is very easy to maintain, low-maintenance, simple, reliable, and economical, capable of cutting up to 300 mm thick. The Bobukh "VOGNIK" 181 cutting torch is such a torch.

Another practical one kerosene cutter without heating - This is the RK200 "VOGNIK" 182, which also meets the same requirements as the "VOGNIK" 181. This cutter does not require centering of the mouthpiece, as the oxygen stream is always adjusted in the center. It works well at temperatures as low as -25°C.⁰With a minimum power setting of 15 seconds, it cuts metal from 3 to 200 mm thick and can pierce metal up to 50 mm thick. It runs on gasoline at a pressure of 0.5-1.5 kgf/cm.², at oxygen pressure of 3 - 8.5 kgf/cm², simple spare parts, easy to repair, always available.

Oxygen-kerosene cutting torch It can cut metals whose combustion temperature in oxygen is below the melting point and the resulting slag must be fluid. The RK2-02 cutter is designed for manual separation cutting of low-alloy and carbon steel and can cut up to 200 mm thick. Nozzle burnout on a kerosene torch This may be due to the pressure of the supplied oxygen, it is necessary to comply with the pressure established by the standards, and may also affect the material from which the nozzle is made, copper and bronze are more wear-resistant.
