Lots of Pumps used in Power Plants according to Hot Topic Speakers

This webinar covers pumps used in a variety of gas turbine combined cycle operations including fogging, boiler feedwaetr, condensate return, cooling, and lubrication. Here is a summary of a previous webinar on this subject plus links to the the new presentations.

Flowserve Boiler Feedwater pumps have beneficial features

This brochure describes pumps offered by Flowserve for combined cycle applications. Flowserve models DMX and WXH are commonly used for boiler feedwater to handle high pressures and fairly high flow rates. Flowserve models APKD and VPC are commonly used for condensate services.

The Rewards of Pump System Optimization

Typically, when talk turns to power plant pumps, boiler feed and cooling water pumps immediately dominate the discussion. And that’s as it should be: these pumps are critical to a plant’s thermal efficiency and availability. They are also the most costly to produce, operate and maintain, so optimizing their efficiency is imperative. However, in terms of reliability and profitability for the entire plant, it is also prudent (and economically rewarding) to optimize pump system performance throughout the entire station.

Eliminating Feedwater Control Valve Damage with Multi-stage, Multi-path Flowserve Control Valves

The feedwater control valve (located downstream of the high-pressure feedwater heaters) performs the critical function of controlling the feedwater flow rate over a wide range of service conditions. During startup and shutdown, the feedwater control valve restricts flow by controlling near the closed position. The pressure drop across the valve is high, which can cause severe cavitation and noise. Over time, these severe service conditions will damage a control valve. Even a properly designed valve will not work well unless it is connected to a correctly sized actuator. An undersized actuator will cause unstable flow conditions while an oversized unit has a slow response to input signals. Flowserve has successfully addressed these issues with specially engineering multi-stage multi-path, or MSMP, designs. MSMP trim channels the flow through a series of orifices to reduce the pressure in stages. This prevents cavitation from occurring inside the valve. The velocity of the feedwater is kept low to prevent erosion of the valve body and to reduce noise and vibration. MSMP trim is customer-designed for the full range of service conditions. MSMP trim prevents cavitation when throttling near the seat but acts like a conventional control valve when controlling near the full-open position. As the pressure drop across the valve decreases, the cavitation also decreases and then stops. To maintain flow rate with decreasing pressure drop, the valve will open further and expose flow paths without orifices. The orifices are not needed at this flow condition because cavitation has stopped.
