A flare pilot assembly has inner and outer tubes, defining inner and outer passages. A manifold delivers air and fuel to the outer passage. A bleed off passage directs a portion of the fuel and air entering the manifold to the exterior of the manifold. A diversion port in the inner tube diverts into the inner passage a portion of the air and fuel flowing through the outer passage. An electrical sparking device ignites air and fuel flowing through the inner passage. An evacuating tube extends from the manifold through the inner passage to the distal portion of the inner tube. The evacuating tube conveys moisture that may accumulate at the distal portion of the inner passage through the bleed off passage to the exterior.

Systems and methods for use with water-fuel supply to industrial engines are provided. A method for controlling water supplied to an engine may include using both a desired water-fuel ratio, and a compensated fuel flow. This compensated fuel flow may be calculated by a controller-implemented complementary filter, which may include receiving, by the controller, a first signal and a second signal. The complementary filter may subtract the second signal from the first signal to create an error signal, lag the error signal to create a lagged error signal, and add the lagged error signal to the second signal to create a compensated signal. The controller may calculate a water flow request using a desired water-fuel ratio and the compensated signal.

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.

In a method for reducing the NOx emissions of a rotary kiln of a clinker production plant, fuel supplied through a burner of the rotary kiln is burned along with primary air fed through the burner, wherein the primary air has a lower oxygen content and the primary air has an oxygen content reduced relative to that of the ambient air and a temperature increased relative to that of the ambient air, and the primary air is obtained by mixing ambient air with exhaust gas from the rotary kiln or from a heat exchanger connected to the rotary kiln and used for preheating raw meal. The primary air is further obtained by mixing with hot air, in particular waste air from a clinker cooler.

The present disclosure describes a system and method for shaping and energizing fluids that can generate luminous fluid sculptures. The method comprises sculpting the pattern and/or shape of a plurality of fluids using nonvisible forces such as mechanically generated turbulence, controlled movement through a shaped chamber, magnetic fields, vibration, gravity, or other forces; energizing the sculpted fluids so that they emit visible light using sources of nonvisible energy such as chemicals, heat, electrical currents, electromagnetic radiation, or other sources; and controlling the color of the emitted light using chemical additives, selected wavelengths of electromagnetic radiation, layering of selected chemicals, or other methods.

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.

The present disclosure describes an assembly configured to mitigate the harmful effects of smelt fouling, airflow interference, and operator exposure to hot air from the furnace and wind box through use of an extractable startup burner and an isolation chamber engaged to a windbox. The present disclosure also describes a method for safely extracting a startup burner from an active recovery boiler as has method for inserting an extractable startup burner into a recovery boiler during operation.
