The specific heat (= specific heat capacity) at constant pressure and constant volume processes, and the ratio of specific heats and individual gas constants - R - for some commonly used "ideal gases", are in the table below (approximate values at 68 o F (20 o C) and 14.7 psia (1 atm)). Liquefied Natural Gas (LNG) For the 2014 SPE Roughneck Camp Chris Caswell, Director – LNG and FLNG KBR July 17, 2014 Remember that natural gas will not provide as much heat as propane, so your forge may not be able to forge-weld. If you use a blower and large jet diamerter you will be able to forge-weld easily. A properly adjusted gas forge will have an air/gas mixture that will create a neutral, or slightly reducing, environment inside the forge.

  1. In a gas heater, propane or natural gas is fed through a gas valve inside the heater and ignited by a sparker or pilot flame. The burning fuel warms a heat exchanger, which activates a fan that blows air through it and out into your garage. The heat from the exchanger warms the air as it passes through, and transfers it to you.
