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： A gas burner is described having a cylindrical combustion chamber having at least two spaced apart counter-rotation stationary tangential air injectors and at least three sets of radial injection holes in between for admitting air under pressure in the combustion chamber to cause adjacent counter-rotation air turbulence regions in said combustion chamber. The combustion chamber has a closed end and an open end with a gas injector tube extending in the chamber from the closed end and disposed centrally therein. The injector tube has combustion gas injection ports at least upstream and downstream of the at least two air injectors to create a combustion mixture which is initially fuel-lean to generate a flame having a lower temperature and producing less nitrogen oxide than with conventional gas burners of this type. An air chamber is provided about at least a portion of the combustion chamber and communicates with the tangential air injectors.

摘要： A controller for an ultraviolet (UV) purification system having UV lamps includes a sensor in communication with a given UV lamp as well as a processor in communication the sensor. The sensor provides the UV light intensity rate of the UV lamp (sensed rate) and transmits this information to the processor which compares the sensed rate with a memory stored desired UV light intensity rate (desired rate). An indicator in communication with the processor indicates when the UV lamp is producing a UV light intensity below the desired rate. Current is provided to the UV lamp by a ballast. The processor includes a memory stored predetermined UV light intensity rate (predetermined rate) that is greater than the desired rate. When the sensed rate is lesser than the predetermined rate, the current provided by the ballast is increased such that the UV lamp produces a UV light intensity at least equal to the predetermined rate.

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).
摘要翻译： 公开了一种用于喷射燃料的逆流燃料喷射喷嘴。 喷嘴包括具有限定喷嘴内部的内表面的喷嘴壁，用于在其中接收燃料的内部。 喷嘴还具有形成在喷嘴壁中的燃料通道，用于将燃料从内部分配到喷嘴外部的位置，燃料以燃料流注入方向分布到外部位置。 在喷嘴外部的位置以主要的空气流动方向设置气流。 燃料流注入方向的至少一个矢量分量与主流气流方向的至少一个矢量分量相反。 以这种方式，通过将燃料以逆流角度分配到空气流中，实现了空气中燃料混合的改进控制。 逆流喷嘴可以作为新燃烧器的一部分而被包括，或者作为对现有燃烧器的改造以包括逆流混合。 有利地，通过使用具有使用FGR的燃烧器的逆流燃料喷射喷嘴（即，供应到燃烧器的燃烧空气中具有较低的O2），燃烧器调节比和稳定性得到增强。
