"Colemans" down here is Propane, or Propane+Butane "power mix".
I've used it to start gas (Propane) start jet Turbines. The "gas" is used for it's fast light-off and to get things nice and glowing - then the Kerosene (paraffin, JetFuel...whatever) ramps in until the Turbine is finally running on 'Kero'.
The more modern engines these days are Kero start i.e. the glow section has a Kero heater to vapourize the fuel and initiate/sustain combustion in the burner can. Commercial RC Turbine technology has come a long way in the last 10 years or so
