Abstract: An enhanced deck for generating live fire simulations of fuel spill and chemical fires and the like includes a receptacle for receiving a volume of fluid such as water within which is mounted a fuel burner array. Gaseous or liquid fuel is delivered to the burner assembly under pressure, resulting in the expulsion of fuel into the liquid, where the fuel transforms into vapor and rises to the surface of the receptacle. A support surface such as a metal grating or other rigid temperature resistant structure is provided at the upper end of the liquid receptacle and is at least partially immersed in the liquid so as to be in heat transfer relationship with the support surface. The fuel vapor is ignited at the support surface to generate a training fire. Preferably, a flow of liquid is provided to the receptacle to replace liquid that evaporates from the heat of combustion to maintain the support surface at or below a predetermined temperature.
