A fire safety protection evaluation system includes at least one horizontal collection device and at least one vertical collection device. The at least one horizontal collection device includes a liquid collection pan with a substantially horizontal opening, a first storage container in communication with the liquid collection pan, and a first measuring device to measure an amount of liquid in the first storage container and/or a rate of liquid entering the first storage container. The at least one vertical collection device includes a substantially vertical liquid collection surface extending between a top edge and a bottom edge, a trough located along the bottom edge to collect liquid from the substantially vertical collection surface, and a second measuring device to measure an amount of liquid and/or a rate of liquid collected by the trough.

A radiative recuperator preheats oxidant and/or fuel for combustion at one or more burners of a furnace. The recuperator includes a duct, at least portions of which comprise a material having a thermal conductivity of greater than 1 W/(m.Math.K), preferably greater than 3 W/(m.Math.K), that receives hot flue gas produced by the burner(s). The duct radiatively transfers heat to oxidant or fuel (for preheating) flowing through one or more metallic pipes disposed in between the duct and an insulating wall.

Submerged combustion burners having a burner body, a burner tip connected thereto, and a protective cap and/or cladding layer. Submerged combustion melters including the burners and methods of using them to produce molten glass. The burner body has an external conduit and first and second internal conduits substantially concentric therewith, forming first and second annuli for passing a cooling fluid therethrough. The burner tip body is connected to the burner body at ends of the external and second internal conduits. The burner tip and protective cap and/or cladding layer include a generally central flow passage for a combustible mixture, the flow passage defined by an inner wall of the burner tip and protective cap.

A mobile vehicle having a burner assembly for movement over a ground surface and directing flame onto the ground surface to incinerate the materials on the ground surface and growing therefrom and including a water spray for reducing air pollution associated with the incineration.

Apparatus and methods of use thereof for the production of carbon-based and other nanostructures, as well as fuels and reformed products, are provided.

A burner with a plurality of oxidant gas pipes distributed throughout the cross section of the burner and process gas in plug flow provides even mixing of the oxidant and the process gas.

According to one implementation a dual-fuel wall heater is provided that comprises a gas burner suitable for receiving a first gas or a second gas, a first pilot burner adapted to the first gas and a second pilot burner adapted to the second gas. The heater includes at least one pressure regulator, a control valve in fluid communication with the pressure regulator, and a selector valve in fluid communication with a gas outlet of the control valve. Each of the first and second pilot burners is arranged to direct a flame toward respective first and second thermocouples. The control valve includes an electromagnetic valve electrically connected to both the first and second thermocouples, the first and second thermocouples being arranged electrically connected in reverse polarity, such that in the event of the second gas being improperly supplied to the first pilot burner the resulting electromotive force generated by the first and second thermocouples is less than a disengagement threshold value of the electromagnetic valve.

The invention is directed to a burner for the gasification of a solid fuel, comprising a burner front having an opening for discharging a solid fuel, wherein the opening for discharging the solid fuel is fluidly connected to a central passage way and wherein the central passage way has a downstream part wherein the diameter of the passage way increases over a first length and subsequently decreases over a second length terminating at the burner front and wherein inside the downstream part of the central passage way a hollow member is positioned, and wherein the hollow member has an internal increasing diameter and inner decreasing diameter aligned with the increasing and decreasing diameter of the hollow member and wherein the connecting conduits have a discharge opening positioned in the diverging part of the hollow member.

Embodiments of integrated burner assemblies, for use in classified hazardous areas, effectively utilize a designated general or non-classified area classification inside a burner housing to simplify wiring connections between various components of a managed burner system. A valve train which supplies fuel to the burner and a control unit which manages the burner assembly and the valve train are mounted external to the burner housing in a classified hazardous area. Mechanically protected wiring is used to connect the valve train and control unit to the non-classified area. The open wiring connections inside the non-classified area, connecting between the burner assembly and the mechanically protected wiring from the control unit and the mechanically protected wiring from the valve train are free of mechanically protection considerations.
