Description
Technical field
The present invention relates to a kind of natural gas for cutting metal；This combustion gas can be utilized for Metal Cutting metal, welding.
Background technology
In China's industrial combustion gas consumption, 70% is propane flammable gas and acetylene gas.Use pure acetylene gas to carbon steel cutting gold
During genus, it is easily generated cutting shoulder and melts, the phenomenons such as dross is many and not easy cleaning, tangent plane differential hardening, make cutting smithcraft not
Ideal, and use pure acetylene environment can cause the biggest pollution, not environmentally.During welding, need to polish, add and produce into
This.Shipyard, coastal area has forbidden using acetylene at shipbuilding platform, uses other novel cutting metal gas instead, for many years
Come the people have attempted to use other fuel instead acetylene as cutting metal gas, but due to other fuel such as natural gas, liquefaction
The fuel ignition temperatures in oxygen such as oil gas, propane flammable gas, propylene gas, artificial coal gas, dimethyl ether are less than 2500 DEG C and cut
Metal speeds is slow, undesirable directly as cutting metal gas, need to add perfect combustion catalizer basis gas is catalyzed, cracking,
Combustion-supporting, change fuel gas buring mode, thus promote flame temperature, it is allowed to burned flame temperature in oxygen and reaches or surmount second
3100 DEG C of alkynes, it is achieved substitute the purpose of acetylene；But after air can be caused exhaust emission, and interpolation by existing perfect combustion catalizer
The calorific value of various fuel be still insufficiently to serve as combustion gas cutting metal.
