A mining or caving lamp has calcium carbide placed in a lower chamber, the generator. The upper reservoir is then filled with water. A threaded valve or other mechanism is used to control the rate at which the water is allowed to drip into the chamber containing the calcium carbide. By controlling the rate of water flow, the production of acetylene gas is controlled. This, in turn, controls the flow rate of the gas and the size of the flame at the burner, and thus the amount of li… WebStudy with Quizlet and memorize flashcards containing terms like How many cubic feet of acetylene gas is stored in a size MC acetylene tank weighing 8.0 pounds?, Why are acetylene cylinders only used in the upright position?, Most air conditioning manufacturers specify that refrigerant lines should be: and more.

WebThe “sweating” water phenomenon that occurs when you preheat material is just a reaction of burning hydrocarbons. If you balance the chemical equation of an neutral oxy-acetylene flame, it looks like this: C2H2 + O2 → 2CO + H2. The basic byproducts are carbon monoxide and hydrogen, which form a secondary reaction resulting in carbon ...
