Boiler Feedwater Pump Efficiency Optimization - Yokogawa
The optimization of boiler feedwaer operations depends on controlling feedwater and drum pressure. The Yokogawa Dpharp can measure pressures up to 2000 psi and can measure across a range of pressures with high accuracy. Significant energy and maintenance reduction is achieved with optimization of pressure differential.

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.

ACS 1000 variable speed drives improve efficiency of CHP power plant
The boiler feed-water pumps at Helsinki Energy‘s CHP plant were controlled by wound-rotor motors with slip recovery control system. In order to reduce maintenance costs and further improve the plant‘s efficiency, the pump drive systems were upgraded with four ACS 1000 variable speed drive systems from ABB (each rated at 4500 kW).

VFD at the Hainan Yangpu 220 MW GTCC
This paper discusses the application of variable frequency drives (VFD) in the high-pressure water feeding system of boilers serving Units 11 through 13 of a combined cycle section of the Hainan Yangpu Thermal Power Plant. The article is written by the plant engineer responsible for the operation and maintenance of the system. In the first year of operation there were severe problems with the valve caused in part by inability to measure the outlet pressure of the BFP system and it was determined that a solution lay with replacing the hydraulic coupling with VFD.

The Sandardized Sulzer Pumps MD Range Meets CCGT Boiler Feed Requirements
Although most once-through HRSGs are sub-critical, their BFPs have to provide very high pressure. In order to increase pressure, BFPs have more stages and shafts with higher torque capacity than conventional pumps. The Sulzer MD range meets these requirements.
