SERVICE FOCUS MAXIMIZE YOUR ANALYZER UPTIME WITH SPARES KITS THE BENEFITS OF COMBINED CYCLE POWER PLANTS F luegas E xact 2700 SPARES BASE PACK Servomex spares kits provide the parts you need to minimize system downtime and keep your analyzer operating in the most demanding conditions. The SERVOTOUGH FluegasExact 2700 monitors oxygen and combustibles in the harshest environments, for example measuring high dew point, acid gas rich samples in high-temperature incinerators. It is rugged and reliable, but when parts inevitably need replacing, it is also quick and easy to maintain. We provide comprehensive spares kits with everything you need to complete a repair or replacement, from main parts, like PCBs or filters, to ancillary items such as seals, gaskets and anti-seize compounds. Base spares kits are offered at the point of sale and ensure you’ll have the critical spares on your shelf should a part need replacing, reducing your analyzer downtime. For example, the popular FluegasExact 2700 base pack includes parts vital to the heating system, spare main filter, fuses, and flange gaskets in case a sensor head is ever removed from the process. Packs of common consumable items – including mounting gaskets or aspirator and flame arrestor seals – are also available, allowing you to hold stock for when it’s needed. The FluegasExact 2700 manual has a full list of available spares and recommended quantities, depending on the number of units in use. This allows you to select the parts you need more easily. You can also download quick reference spares sheets from the Servomex website, which show compatibility for previous and current 2700 variants. These can be conveniently stored or placed near the analyzer for quick reference. And, if you don’t have the parts you need, our network of Business Centers holds extensive stocks of all key spare parts, enabling them to provide a 48- hour despatch on all stocked spares, so you get the parts quickly.

NOx and CO reduction is key for Gas Turbine Combined Cycle (GTCC) plants and, in some cases, all that is needed is lean-burn air/fuel ratio control, plus a dry low-NOx (DLN) combustor, which premixes the fuel and air for a more even heat production. Post-combustion technologies designed to lower NOx and other emissions include Selective Catalytic Reduction (SCR), Selective Non-Catalytic Reduction (SNCR), selective CO and NOx catalyst reduction, or the addition of fogging (water or steam injection). The technology used depends on the turbine size, the regulatory requirements, and the environmental impact. Advanced operational control using sensors or analyzers located in and around the heat recovery steam generator (HRSG) housing is used to balance operational efficiency against regulatory emissions, but because there is not much room inside or out of the HRSG, analyzers need to be as compact as possible. Extractive-based analyzers face a number of obstacles when deployed in a GTCC plant. The biggest challenge comes from corrosion of the probe due to the high shear forces and the fluctuating temperatures and pressures coming from the exhaust gas exiting the turbine. Analyzers placed farther downstream will benefit from lower and less turbulent flows; however the time lag of the analyzer response may now pose a problem, especially when used for safety purposes during the turbine start-up.
