OXY-HYDROGEN FLAME FOR CUTTING OF STEELS:
INTRODUCTION:
Thermal cutting, i. e. Gas cutting, is a wide-spread technology. In practical applications, gases such as propane-butane and acetylene prevail. Hydrogen is practically not used due to its high production cost and its explosiveness.
In the first part of the paper, a device for production of an oxygen-hydrogen mixture is described and some basic characteristics of oxy-hydrogen cutting are indicated.
BASIC CHARACTERISTICS OFCOMBUSTION OF HYDROGEN AND OXYGEN:
Hydrogen is a colourless, odourless, and tasteless elementary gas. It is not poisonous. In nature it is rarely found in its atomic form. With an atomic weight of 1, 008, it is the lightest known substance. It is flammable. Aflame temperature in hydrogen combustion in air attains 17000 ° C, and in oxygen 2400 ° C. When mixed with air, hydrogen forms an explosive mixture (an explosive gas). Its ignition temperature is 560 ° C whereas its explosion range is from 4 to 75 vol. % at atmospheric pressure. The equation showing the chemical reaction of complete combustion of hydrogen and oxygen is as follows:
H2+ 0.5 O2 →H2O,
2 kg + 16 kg →18 kg.
The main properties of hydrogen are as follows:
- the lightest gas (fourteen times lighter than air),
- high thermal conductivity (seven times higher than that of air),
-high diffusibility(five times higher than that of methane).
-Minimum energy required for ignition(five times lower than that required for petrol),
- high rate of combustion (eight times higher than that of petrol).
What is HHO Flame Cutting Machine:
Oxyhydrogen Generator/Metal Cutting Machine consumes water and electricity, electrolyze water into H2 and O2,
We can use H2 and O2 as source of flame replacing acetylene or natural gas or other fuel.
Oxyhydrogen Generator/Metal Cutting Machine is used for welding, cutting, polishing, brazing, glass processing and jewelry processing.
Also can burst with other fuel together for heating.
Multi-functions application:
1. Carbon Steel Cutting of machine building industry, shipyard, steel structure processing plant.
2. Continuous casting slab cutting of Steel Plant.
3. Cooperate with manual cutting torch, semiautomatic cutting machine, shape cutting machine, CNC cutting machine to instead of traditional fuel gas.
Features of Kingkar HHO Flame Cutting machine compared with acetylene propane etc. Gas fuel:
1. Oxyhydrogen gas flame is concentrated. Preheating time is short in the same energy condition. This provides higher heat transfer rate,
Higher piercing speed and faster cutting.
The shorter piercing time and increased cutting speed provides a significant cost saving when compared with LPG fueled cutting.
