Which type of fuel is commonly used in gas-fired live fire training structures?

The commonly used fuel in gas-fired live fire training structures is propane (LPG). This choice is favored for several reasons related to safety, control, and ease of use in training environments.

Propane burns cleanly and produces a consistent flame, which makes it ideal for creating realistic fire scenarios without excessive soot or toxic emissions. This aspect is crucial during training to maintain a safe environment for trainees and instructors alike. Furthermore, propane is readily available and can be easily transported and stored, making it a practical option for training facilities.

In the context of training, the ability to control the intensity and duration of the fire is paramount, and propane allows for this manipulation due to its adjustable flow rates. This ensures that instructors can tailor scenarios to meet specific training objectives while ensuring the safety of participants.

Other fuels, such as natural gas or butane, may also be used in some settings, but propane tends to be preferred in many cases due to its availability and favorable combustion properties. Diesel is less commonly used in gas-fired training structures, as it is typically associated with different training requirements, mainly involving heavy apparatus or vehicles.
