While propane-oxygen combinations can reach a maximum temperature of 3,623 degrees F, or 1,995 degrees C, a propane-butane torch only goes up to 2237 degrees F, 1225 degrees C. A torch flame consists of two cones, an outer light blue flame and an inner dark blue flame. So Propane, as an LPG, is most suitable for exterior storage and use. Butane Gas. I have read that butane "burns hotter" does this make it more efficient in terms of cooking quicker and heating "warmer" when using a gas space heater. Pure propane, for example, is liquid at -44°F/-42°C at sea level. As butane seems to cost more (7kg butane £15.49 Vs 6kg Propane £14.49 on calor website) is it used at a slower or faster rate, therefore given a certain useage which would last longer. LPG, or Liquefied Petroleum Gas, is the term widely used to describe a family of light hydrocarbons. It burns at about the same temperature as propane, but may cost more.MAPP gas may burn too hot for your application. LPG, or liquefied petroleum gas, is a common mixture of the two substances. In a torch, it can be used for soft soldering copper pipes.The least toxic of the three, butane burns the cleanest, and you can safely store it indoors. We will also find out how reliable they can be when used in stoves! The key difference between propane, isobutane and butane is what’s referred to as their “vapor pressure.” Vapor pressure describes a fuel’s ability to vaporize and keep the canister pressurized at a given temperature. The two most prominent members of this family are propane and butane.Both types of gases are used for industrial and household purposes and have similar qualities that is why people often confuse them. MAPP gas may burn too hot for your application. The first fact consumers need to know about butane is this: Often when we talk about butane and propane that is sold commercially, the actual product is in fact a mixture of the two. After founding a small telecommunications engineering corporation and visiting 37 countries, Asmus studied broadcasting at Arizona State University and earned his Master of Fine Arts at Brooklyn College in New York. It burns at about the same temperature as propane, but may cost more. Propane has a lower boiling point than butane so it will continue to convert from a liquid to a gas even in very cold conditions, down to -45ºC. In this article, we will take a look at the similarities and differences of butane vs propane camp stoves. When released into the torch, they evaporate and the gas mixes with air and burns.MAPP gas, made from combining liquefied petroleum and Methylacetylene-Propadine, burns the hottest. Butane will not evaporate at lower temperatures so torches won't work below freezing.Richard Asmus was a writer and producer of television commercials in Phoenix, Arizona, and now is retired in Peru. Your choice between MAPP gas, butane or propane depends on your application. 2. Butane vs propane are dissimilar in boiling point and vapour pressure but both are regarded as LPG and commonly used for cooking, heating, hot water and autogas. Butane and propane, both combustibles and derived from petroleum, are often and commonly used as cooking fuels especially in portable stoves for camping. The lower boiling point of propane is advantageous, as it will continue to vaporise – turn to gas – even in colder climates down to -42°C. For safety, you should store propane outdoors. Best uses include hard or silver soldering and brazing.Propane, the most common of the three, does not burn as hot as MAPP gas, but is available at more retail outlets in more forms. LPG fuels exist as liquid under high pressures and in cold temperatures.
