Propane torch
From Wikipedia, the free encyclopedia
A propane torch is a tool for burning the flammable gas propane. The maximum adiabatic flame temperature a propane torch can achieve with air is 2268 Kelvins (1995 °C/3623 °F). Some propane torches are also used with a tank of pure oxygen to achieve a flame temperature nearing 3095 Kelvin (2820 °C/5110 °F).
The temperature in these flames is lower due to not total oxygen gain of combustion, heat loss in combustion, oxygen quantity etc.
Propane torches are frequently employed to solder copper water pipes. It can also be used for some low temperature welding applications, as well as for brazing dissimilar metals together.
