The variety burning gas that in lighting gas to be produced at present, uses and their main character sees a table 1, dosage is most before is acetylene, in recent years, because propane is low-cost, use safety, gas source is adequate, etc of acetylene of integrated effect excel burns gas, reason dosage increases greatly. Express 1 blaze cut to use burn gas main character lights air sort density of opposite element quality / (below Kg/m3)(mark condition) high fever is worth / (below Kg/m3)(mark condition) low calorific value / (Kg/m3)(mark condition falls) explosion limit (%) oxygen / , boiling point temperature) lowermost ignition temperature / temperature of ℃ combustion calorimeter / ℃ acetylene 26.

Aerobic oxygen is used in blaze cut the amount is larger. What our country majority uses is bottled and gaseous oxygen, its defect is quality is not stabilized, influence cut quality and efficiency and increase cost amount, create many steel jar and the waste of carriage time. Use liquid oxygen its advantage is quite big. Because oxygen is opposite in the liquid reserve big, carriage efficiency is tall, angry style quality is good, auxiliary the merit with little time, use at blaze cut to be able to improve work efficiency and cut quality greatly, be worth to be popularized energetically.
