摘要： The inlet arrangement comprises two inlet ports for a fuel and air mixture each of which terminates at an orifice openable and closeable by a respective valve. Each inlet port is of a high flow/low swirl type and a mixture of fuel and air which flows through the orifice can be deflected to enable the inlet port to perform as a low flow/high swirl at smaller throttle openings. In one embodiment, flow of mixture through the inlet port can be deflected at low throttle openings by a transverse flow of gas from inlet ducts. In other embodiments, the direction of mixture flow can be varied by members movable into and out of the mixture flow.
摘要翻译：入口装置包括用于燃料和空气混合物的两个入口端口，每个入口终止于可由相应阀门打开和关闭的孔口。每个入口端口具有高流量/低涡流型，并且流过孔口的燃料和空气的混合物可能被偏转，以使入口端口能够在较小的节流孔处作为低流量/高涡流。在一个实施例中，混合物通过入口端口的流动可以通过来自入口管的横向气流从而在低节气门开口处偏转。在其他实施例中，混合流的方向可以通过可移入和流出混合流的构件而变化。

摘要： In a boiling water reactor, provision is made to sample the core bypass region immediate the top guide to determine the physical and chemical constituents of the moderating water. A conduit for a local power range monitor is fitted with a measurement assembly. The conduit and measurement assembly are inserted up to the vicinity of the top guide. A tube opening is provided to the bypass region immediate the top guide. During reactor operation, the saturated liquid in this region flashes to a steam water mixture (18% steam) at constant enthalpy and is rapidly removed from the reactor to measuring equipment in the reactor building. During removal, the radiolytic disassociated gases (namely hydrogen and oxygen) partition to the steam phase where their recombination is retarded and accurate measurement of their constituent content can be made. Also, temperature of the steam water mixture decreases thereby preserving unstable species like hydrogen peroxide that degrade much more rapidly a high temperatures. In the reactor building, the gases are further cooled, condensed and divided with a first stream being diverted and cooled for detailed chemical analysis and a second stream reheated and pressurized for measurement of electrochemical potential. A substantially real time measurement of the chemical state of the reactor to enable monitoring, measurement, and correction of harmful imbalance is provided.
