Economizers

Economizers are commonly used as part of a heat recovery steam generator (HSRG) in a combined cycle power plant. A common application of economizers in steam power plants is to capture the waste heat from boiler stack gases (flue gas) and transfer it to the boiler feedwater.

Auto Recirculation Valves

Pump protection valves are required to ensure the minimum flow rate of a pump at all times. This protects the pump against overheating, cavitation and finally, destruction. If the flow through the pump falls below a certain level the bypass system opens and the fluid will be recirculated providing the required minimum flow for the pump

Turbine Drain/Turbine Bypass Valves

KEI offers a variety of turbine bypass solutions. The Circor video link below demonstrates how the bypass diverts steam from the turbine to the next level steam header, or condenser. This application sees high pressure drop and thermal shocks, requiring tight shutoff with fast response. Startup conditions require special trim for cold start requirements.

Soot Blower Valves

Fouling of the boiler tubes is a concern when firing fuels such as coal, oil, biomass, and other waste. Deposits from the combustion process can accumulate on the boiler tubes, causing operational difficulties and reduced thermal efficiency. KEI works with plant personnel to resolve soot blower issues and provides reliable valve isolation and control solutions.

PORV

The MOGAS PORV, a pneumatic actuated pressure relieving valve, prevents excessive system pressure accumulation. The set pressure of the PORV is lower than that of the spring-loaded safety valve to prevent or reduce the number of lifts of the safety valve, thus extending their life.

  • Mogas
  • ASME “V” Stamp
  • Live loading ensures zero emissions
  • Field repairable
