The generators that run on propane are known as best propane generators. They may be single fuel or bi and tri-fuel. Propane is a hydrocarbon with 3 carbon and 8 hydrogen atoms (C3H8) in its molecule. Water boils at 100°C and turns into steam. While propane boils at -42°C to become vapour. Propane is called Liquefied Petroleum Gas(LPG) because it is pressurized into a gas cylinder. It turns back into vapour when the pressure is released.
Thus, the mechanism that facilitated its use is in the extraction from the cylinder in which it is supplied. Most applications and appliances such as water heaters, generators, cookers use vapour.In its natural state, it is colourless, odourless and looks like water. Thus, for safety, a smell or an odorant is added to the gas so that a gas leak could be detected. This gas is extremely flammable. In the event of a leak ensure there are no flames or sparks and static electricity in the vicinity, and also allow thorough ventilation. Propane is heavier than air thus sinks to the floor, ensure a proper dispersal of the leak by opening all windows and doors.

Propane burns readily with oxygen and has a high energy content. It burns at 1980°C with a blue flame. This means it also burns clean and completely leaving behind only carbon dioxide, water and heat. The heat powers the internal combustion engine. As the engine turns the generator produces electricity.There is 25MJ (Mega-Joules) of energy in one litre of propane. The base unit is Joule it is the unit of work.
And energy is required to do work. A Mega-Joule is a million times a joule. Gas consumption is expressed in Mega-Joules per hour (MJ/hr). This translates to how much gas consumed or work (in MJ) was done in an hour (in this case, turning the engine in RPM).25MJ per litre converts to 6.9kWh. A kWh equals the amount of energy required to run a 1000-watt appliance for an hour. This means, on 6.9kWh you can run this appliance for 6.9 hours on one litre of propane. A twenty-pound tank contains 9.0718litres of propane. This means you can achieve a runtime of approximately 9 hours per tank.
