摘要： A purge system is disclosed for flushing liquid fuel and water from the combustion section of a gas turbine system as well as for providing continuous cooling of the nozzles. The gas turbine may operate on liquid fuel or gaseous fuel. When the turbine is switched to burn gaseous fuel, the liquid fuel remaining in the liquid fuel system is flushed by a liquid fuel purge system. Similarly, water in the water injection system is purged from nozzles in the combustion system by a water purge system. The purge system operates in conjunction with an air atomization system, but does not rely on an atomizing air compressor to boost the pressure of the purge air. Instead, the purge system utilizes pressurized air from the gas turbine compressor and directs the purge air to manifolds which distribute air to the atomizing air passages, liquid fuel nozzles, and water injection nozzles via purge valves and soft purge valves.
摘要翻译： 公开了一种用于从燃气轮机系统的燃烧部分冲洗液体燃料和水以及用于连续冷却喷嘴的清洗系统。 燃气轮机可以在液体燃料或气体燃料上操作。 当涡轮机切换燃烧气体燃料时，残留在液体燃料系统中的液体燃料被液体燃料净化系统冲洗。 类似地，注水系统中的水通过净水系统从燃烧系统中的喷嘴中清除。 净化系统与空气雾化系统一起工作，但不依赖于雾化空气压缩机来提高净化空气的压力。 相反，吹扫系统利用来自燃气涡轮压缩机的加压空气，并将净化空气引导到通过净化阀和软吹扫阀将空气分配到雾化空气通道，液体燃料喷嘴和水喷射喷嘴的歧管。

摘要： A fuel cell system includes a fuel cell stack, an enclosure housing the fuel cell stack and a blower. The blower is located inside the enclosure and is adapted to draw air from inside the enclosure to produce an air flow through the fuel cell stack and establish a negative pressure inside the enclosure with respect to a region outside of the enclosure.

摘要： The invention provides filtration systems and associated methods for filtering a fuel cell reactant stream of particulate and vapor contaminants. In one embodiment, the invention provides a reactant filtration system for a fuel cell, including a first filter having a first inlet and a first outlet, and a second filter having a second inlet and a second outlet. The first filter includes a textile particulate filter, and the second filter includes an activated carbon material. The first and second filters are coupled such that the first inlet is adapted to receive a flow of reactant, which is flowed through the first filter to the first outlet and then to the second inlet, through the second filter and then through the second outlet, which is coupled to an electrode chamber of a fuel cell.
