(UEL). - correct answer ✔✔ The explosive range is the difference between the lower explosive
unit and the upper explosive limit of combustible gases.
LEL - correct answer ✔✔ the lowest concentration (air-fuel mix) at which a gas can ignite.
Concentrations below this are too lean to burn.
UEL - correct answer ✔✔ the highest concentration of (air-fuel mix) at which a gas can ignite.
concentrations above this limit are too rich to burn.
