Abstract: A low-profile burner assembly (LPBA) with pilot for creating realistic firefighter training fires in a controlled setting. The LPBA generally includes a sealed pipe fitting shell with a fuel inlet for inputting combustible fuel, an air inlet for inputting air to be mixed with the fuel, a spark ignition system coupled to the pipe fitting shell for igniting a pilot flame, and a main burner outlet for outputting a combusting air/fuel mixture to create a firefighting training flame. Fuel is distributed within the pipe fitting by an internal distribution tube for metering pilot and main burner portions, and for proper mixing with air. In addition, a sensor probe assembly is provided for monitoring the LPBA. All internal components are well-protected from the high-pressure spray of extinguishing agents by a transport/deflector assembly.

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.
