Cenal Elektrik is building a new 2x660 MW ultra-supercritical coal-fired power plant near Çanakkale on the coast of Turkey’s Sea of Marmara. Using the ultra-supercritical thermal power plant technology will increase the efficiency of the power plant while reducing its emissions. Sulzer was awarded for • 5 HPT boiler feedwater pumps • 5 HZB booster pump • 4 SJT condensate extraction pumps • 5 SJM circulating water pumps • 4 SMD closed-cycle cooling water pumps • 10 general service water pumps (LP heater drainage, steam turbine house sewage and air pre-heater LP flushing water pumps) Sulzer’s efficiency on boiler feedwater and circulating water pumps which was higher than competition made the difference.

Microdyn membranes purify ash pond water for boiler feedwater make up
In order for a technology to be a viable treatment option, the TSS of the pond had to be reduced from 3,000 mg/L down to 10 mg/L. Despite the severe TSS loading, the iSep UF pilot module was able to successfully handle the coal fines loading while providing high quality effluent that far exceeded their discharge permit requirements. No UF pretreatment was required for the modules to successfully operate on the ash pond water.

Continuous-Blowdown Block Valve Reduces Startup Time
At Essential Power LLC’s Newington Energy Facility, the high-pressure (HP) steam-drum continuous blowdown system was designed to cascade flow to the intermediate-pressure (IP) steam drum. While the valve worked well for controlling flow, it did not have the degree of leak-tightness required for stopping flow from the drum during typical overnight shutdowns. An automatic full-port ball valve was installed upstream from the existing automatic control valve to eliminate the risk of flashing.

Electric Fuel Control Valve Streamlines Plant Operations
A Frame 6B-powered cogen plant in California was plagued with fuel-gas valve problems, usually requiring at least a man-shift’s worth of work each outage to disassemble, clean seats/plugs, and reassemble. One solution is to reheat the fuel gas to above the dew point (120-130F) in between the valves, but this is considered far from ideal. The better solution proved to be replacing the original valve with a “smart” electric control valve in the same location as the original and a separate solenoid-operated stop/isolation valve about 6 ft upstream—just outside and below the turbine enclosure.
