摘要： A system for discharging inert gas for extinguishing or suppressing a fire is disclosed. A fluid discharge control arrangement is positioned in a fluid flow path between a pressurised gas supply 10A,10B,10C and the target fire suppression zone 20. The fluid discharge control arrangement reduces the pressure in the fluid flow path downstream thereof. This may allow the downstream pipework to be selected to withstand a lower pressure than in a conventional system in which the fluid discharge control device was not provided, thereby reducing costs. The fluid discharge control device may comprise a first valve 30 and first restrictor 26 in the first flow path 22 and a second valve 32 and a second restrictor 28 provided in the second flow path 24. Fluid from the containers 10A,10B,10C flows initially through flow path 24 and restrictor 26. Subsequently flow path 22 may be closed by optional valve 30, and flow path 24 is opened by valve 32. Fluid flow then passes through restrictor 28. This reduces the peak pressure in the downstream pipework 34. In another embodiment the discharge of inert gas from the containers 10A,10B and 10C is staggered to reduce the peak pressure in pipeline 34. A further embodiment provides a restrictor in the inlet 14A,14B,14C from each of the containers 10A,10B,10C to the manifold 16, thereby also reducing the peak pressure in the pipeline 34.

摘要： A fire and explosion suppression system comprises a source (5) of high pressure water which is fed to a misting nozzle (13) at one input of a mixing unit (6), and a source (14) of high pressure inert gas, such as nitrogen, which is fed along a pipe (20) to another input of the mixing unit (6). Inside the mixing unit (6), water mist, in the form of an atomised mist of very small droplet size is mixed with the pressurised gas and exits the mixing unit (6) at high pressure and high velocity along a pipe (22) and is thence discharged through spreaders (26, 28). The source (5) of the water is pressurised by a feed (30) from the source of pressurised inert gas. The mass flow rate of the water will therefore reduce as the pressure of the gas decays. This tends to maintain the ratio of the mass flow rate of the water to the mass flow rate of the gas constant. This is found to produce and maintain an advantageous distribution of droplet size in the discharged unit. A control unit (10) adjusts a metering valve (7) in dependence on the mass flow rate or the pressure of the gas in order to adjust the ratio as necessary to maintain its value constant.

摘要： In use of a UV gas discharge tube (such as used in flame monitoring apparatus), an electric field is periodically applied in the tube, each application of the field being followed by an ‘off’ period in which the field is removed. During this process, the mean value of the statistical lag Ts is measured over a predetermined time duration (the statistical lag is the time lag after each application of the electric field to the tube before conduction (if any) takes place). If the statistical lag lies within region I, the flame is judged to be present. If the statistical lag lies in region II, the flame is judged to be off (and a warning may be signalled). If the statistical lag lies in region III, a fault in the tube is signalled. This may be a “field emission” fault whereby free electrons are generated by the applied electric field, without the presence of UV radiation or it may be a “multiple counting” fault. Here, contamination of the gas within the tube causes the time required to de-ionise the gas, when the electric field is removed, to be increased. A multiple counting fault may be confirmed by monitoring each conduction of the tube and checking whether there is an immediately following conduction. A multiple counting fault may also be checked by increasing the lengths of the ‘off’ periods of the electric field and checking whether the mean statistical lag increases. The use of a supplementary light source is also disclosed which periodically illuminates the tube to check whether it has become room-light sensitive—that is, sensitive to normal ambient light.
摘要翻译：在使用UV气体放电管（例如用在火焰监测装置中）的情况下，在管中周期性地施加电场，场的每次施加都跟随着除去场的“关”期。在该过程中，在预定的持续时间内测量统计滞后T s的平均值（统计滞后是每次在导通之前向管施加电场之间的时间滞后（如果有的话））发生。如果统计学上的滞后在I区内，则判定火焰存在。如果统计学上的滞后在于区域II，则判断火焰熄灭（并且可能发出警告）。如果统计学上的滞后在于区域III，则发出管道故障。这可能是一种“场发射”故障，其中通过施加的电场产生自由电子，而不存在UV辐射，或者它可能是“多重计数”故障。这里，管内的气体的污染导致当除去电场时使气体去离子所需的时间增加。可以通过监测管的每个导通并检查是否存在紧随其后的传导来确认多重计数故障。也可以通过增加电场的“关闭”周期的长度并检查平均统计滞后是否增加来检查多重计数故障。还公开了使用补充光源，其周期性地照亮管以检查其是否变得对室内光敏感，即对正常环境光敏感。
