LPG has a higher calorific value (94 MJ/m³ equivalent to 26.1kWh) than natural gas (methane) (38 MJ/m³ equivalent to 10.6kWh), which means that LPG can not simply be substituted for natural gas. In order to allow the use of the same burner controls and to provide for similar combustion characteristics, LPG can be mixed with air to produce a synthetic natural gas (SNG) that can be easily substituted.
