摘要： A counterflow fuel injection nozzle for injecting fuel is disclosed. The nozzle includes a nozzle wall having an interior surface that defines a nozzle interior, the interior for receiving a fuel therein. The nozzle further has a fuel passageway formed in the nozzle wall for distributing the fuel from the interior to a location exterior of the nozzle, the fuel distributed to the exterior location in a fuel flow injection direction. An airstream is provided in a prevailing air flow direction in the location exterior of the nozzle. At least one vector component of the fuel flow injection direction opposes at least one vector component of the prevailing air flow direction. In this manner, by distributing fuel into an air flow at a counterflow angle, improved control of mixing of the fuel in the air is achieved. The counterflow nozzle may be included as part of a new burner or as a retrofit to existing burners in order to incorporate counterflow mixing. Advantageously, burner turndown ratios and stability are enhanced through the use of the counterflow fuel injection nozzles with burners that use FGR (i.e., have lower O2 in combustion air supplied to the burner).

摘要： Disclosed is a chemical and biological air purifier. The air purifier has a housing having an inlet and an outlet both aligned on a longitudinal axis, a turbulence generator, one or more vacuum ultraviolet (UV) sources achieving a chemical purification and one or more germicidal ultraviolet (UV) sources achieving the biological purification. The turbulence generator is mounted within the housing downstream of the inlet and promotes a dispersion and mixing of air received through the inlet. The vacuum UV source is mounted within the housing downstream of the turbulence generator and breaks oxygen molecules into mono-atomic oxygen which then reacts with chemical contaminants present in the air and degrades them by successive oxidation to odorless and inoffensive byproducts. The turbulence generator reduces the production of ozone by increasing the contact between the mono-atomic oxygen and the chemical contaminants. The germicidal UV-C source is mounted within the housing parallel to the longitudinal axis of the housing downstream of the vacuum UV source. The germicidal UV-C source, in use, kills biological contaminants present in the air by irradiation and degrades residual ozone produced by the vacuum UV sources into molecular oxygen, thereby purifying air from the biological contaminants and residual ozone.

摘要： A burner is provided for heating a stream of combustion supporting gas, like air. The burner has a main feed pipe extending across the stream of combustion supporting gas. The main feed pipe has an inlet for receiving a fuel gas from a fuel gas source, and at least one outlet for producing a main jet of fuel gas substantially in the direction of the stream. The burner also has two parallel auxiliary feed pipes extending across the stream of combustion supporting gas, at a predetermined distance downstream from the main pipe and on each side of the main jet. Each of the auxiliary feed pipes has an inlet for receiving fuel gas from the fuel gas source, and at least one outlet for producing an auxiliary jet of fuel gas in the direction of the stream. The burner further has two bluff-body devices in front of the outlets of both the auxiliary feed pipes respectively. Each of the bluff-body devices has a hole aligned with each corresponding outlet in order to produce a stable pilot flame adjacent to the main jet of fuel gas for ignition thereof. This burner is useful since it allows for a better mixing of the fuel gas with the stream of combustion supporting gas. Such in turn allows for a better combustion of the fuel gas and, hence, a reduction of pollutant emissions.

摘要： An air-cooled oxygen-gas burner for use with a direct fired furnace. The burner comprises a body formed from three concentric metal tubes supported in a cylindrical housing secured about a conical bore in a refractory side wall of a furnace. The three concentric tubes have a cone shaped inner end which are adjustable to define a nozzle with annular openings therebetween of variable size to vary the shape of a flame produced by a mixture of combustible gas, oxygen and air fed under pressure, respectively, in each of two chambers defined between the three concentric metal tubes and a chamber defined between the tubes and the cylinder housing. The combustible gas is fed in the inner chamber, the oxygen in the intermediate chamber, while the air is fed in the outer chamber to cool the concentric tube assembly and the furnace refractory about the burner nozzle. The tube assembly can be retracted within the cylinder housing so that the nozzle is protected from the high heat within the furnace after the burner is shut off.
