20140099591 | DUCT BURNER OF HRSG WITH LINER FILM COOLING - A duct burner assembly for a HRSG having a casing that defines a combustion chamber with a liner for communicating an exhaust gas. A firing runner attaches to the liner and extends through the combustion chamber. The firing runner defines a plurality of orifices for emitting combustible gas and sustaining a flame. A flame stabilizer attaches to the firing runner and is configured to at least partially shield the plurality of orifices from the exhaust gas. A guide plate attaches to the firing runner and is configured to define a slot between the liner and the guide plate. The guide plate has an upstream end and a downstream end wherein the downstream end is closer to the lining than the upstream end to reduce turbulent flow of the exhaust gas through the slot and cool the liner. | 04-10-2014 |
20140044634 | Ammonia Injection System For An HRSG - A heat recovery steam generator includes a casing for receiving exhaust gas from a turbine, a heat exchanger positioned within the casing for thermal communication with the exhaust gas, and an ammonia vapor distributor positioned within the casing. An ammonia vaporization unit is configured for conversion of aqueous ammonia to ammonia vapor and communication of the ammonia vapor to the distributor. A first extraction line operatively connects between the casing and the ammonia vaporization unit for communication of exhaust gas to the ammonia vaporization unit. A second extraction operatively connects between the casing and the ammonia vaporization unit for communication of exhaust gas to the ammonia vaporization unit. A catalytic reduction system is located within the casing and positioned downstream from the distributor for effecting a reaction between the ammonia vapor and NO | 02-13-2014 |
20140041839 | MULTIDRUM EVAPORATOR - An evaporator for a heat recovery steam generator has two horizontal steam drums of moderate size, one located slightly higher than the other. It also includes a coil having tubes located in the flow of a hot gas. The lower drum communicates with the inlets of the tubes for the coil. The outlets of the tubes communicate with the upper drum. A drain line connects the bottom of the upper drum with the lower region of the lower drum, so that water will flow from the upper drum to the lower drum. Water, which is primarily in the liquid phase, enters the lower drum through an inlet line and mixes with water from the upper drum. The mixture flows through into the coil. Here some of it transforms into saturated steam while the rest remains as saturated water. The saturated steam and saturated water flow into the upper drum where the steam escapes and the water flows back into the lower drum to recirculate through the coil. Owing to their moderate sizes, the drums can withstand high pressures without having excessive wall thickness, and this enables the evaporator to be set into operation with minimal or no hold points. Yet the two drums provide a retention time—and the protection that it provides—of a single large capacity drum having substantial wall thickness. | 02-13-2014 |
