Industrial Applications :
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, semi-automatic cutting machine, shape cutting machine, CNC cutting machine to instead of traditional fuel gas.
The "kingkar" Hydrogen gas cutting system consists of a gas generator and a flame cutting machine.
The gas generator generates Hydrogen and Oxygen from water by electrolysis.
This system features low operating costs and environmental benefits because of no emission of CO2 or poisonous gases.
The gas generator can also be connected to conventional flame cutting machines.
FEATURE:
Machining time reduced by 20~30%
As the combustion rate of Hydrogen gas is faster than that of other fuel gases, the Hydrogen flame is narrower and more concentrated.
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.
Lower heat stress
Steel plate when heated for the same time by both conventional and Hydrogen fueled flames shows the following heat distribution in the plate.
The high combustion speed of the Hydrogen flame reduces the flame area and concentrates the thermal energy.
This allows the high pressure oxygen passage to heat only the immediate area being cut, preventing excessive heat transfer to the surrounding area.
This reduces cooling time and distortion caused by excessive heat stress.
Improved quality of the cut surface
The surface of the cut edge is smooth and dross free, reducing or eliminating the need for secondary processing.
On-Site gas production
This system produces Hydrogen gas on site as required. Consequently there is no storage of high pressure gas required. The machine does not need any special installation or certified or skilled personnel for handling of compressed gas cylinders.
Safer fuel gas
Mixture of flammable gas and air or Oxygen is explosive, and it has a lower and upper limit of concentration for explosion.
Lower explosive limit for Propane gas = 2.2%
Lower explosive limit for Acetylene gas = 2.5%
Lower explosive limit for Hydrogen gas = 4.0%.
Thus, Hydrogen is much safer than the other gases because of its higher value of Lower Explosive Limit. Additionally, because Hydrogen is lighter than air, it does not stagnate but will quickly diffuse in the atmosphere.
CO2 Emissions reduction
Hydrogen is a clean energy source. Water is the only product of combustion. Hydrogen combustion produces no CO2 because the molecule contains no Carbon atom, Hydrogen is the cleanest energy as an alternative to LPG, Acetylene gas or Natural gas.
