At present, oxy-hydrogen generator (water cutting machine) have been known by the carbon steel industry. and is beginning to replace some traditional gas cutting method as for its prominent superiority.
The water cutting machine can be wide application of mental,steel,copper pipe cutting etc.

Compared with acetylene,propane etc, its advantages are mainly reflected in the following respects:
(1) Compared with acetylene and propane flame, oxy-hydrogen gas flame is concentrated.
Preheating time is short in the same energy condition
(2)Compared with other fuel cutting, the affect zone of oxy-hydrogen flame is small.
(3) Oxy-hydrogen gas cutting machine is barely have hang slag, cutting section have a good vertical.
The following left picture is Oxy-hydrogen Cutting, the right picture is acetylene cutting.

(4)Oxy-hydrogen generator( water cutting machine) has no pollution, no black smoke when burning,
it is environmental friendly and not harm for people’s body.
Oxy-hydrogen generator(water cutting machine):
2H2+O2à 2H2O, only water vapor generated (it just formed water vapor) in the cutting process,
no any carbon emissions.
|
Acetylene cutting:
2C2H2+5O2à4CO2+2H2O, there is carbon dioxide emissions.
|
Oxygen-propane cutting: C3H8+5O2à 3CO2+4H2O, there is carbon dioxide emissions.
|
Furthermore, Hydrogen gas is non-toxic and tasteless but acetylene, propane and other industrial gas include sulfide
lead compounds and etc. harmful substances, they will cause respiratory disease if workers inhaled.
(5) Energy saving effect is prominent.
A) Oxy hydrogen gas generator (water cutting machine) uses water and electricity, electrolyze water into H2 and O2,
no need gas cylinder, this way saves the cost of gas cylinder leasing fees of handling and storage.
B) Oxy-hydrogen generator (gas cutting machine) produces some low pressure oxygen by itself, preheating oxygen
can be saved, there just need some hyperbaric oxygen.
Test tool: stopwatch, mass flow meter, three-phase watt-hour meter, straight line cutting machine
Test steel plate: 1m long, 60mm thick steel plate
Test method: take the average of ten times test
General data:
Propane: $1.39/kg Acetylene: $3.15/kg
Oxygen: $2.5/bottle=$0.41/m3 Electricity: $0.13/degree
