EDI for Power Plants -- Importance of silica
Power plants use high purity water to drive steam turbines. Cogeneration plants are highly efficient, using both exhaust turbines and high pressure steam turbines. In the 1960's, boilers operated at 450C (840F) and 4MPa (40 atmospheres). Today's leading edge boilers operate at 620C (1150F) and 30MPa (300 atmospheres). To keep power efficiency high, maximize uptime, and minimize turbine ...

Electrodeionization for Power Plants — Importance of Silica
Power plants use high purity water to drive steam turbines. Cogeneration and combined-cycle power plants are highly-efficient, using both exhaust turbines and high-pressure steam turbines. The steam must be of the highest purity. In the 1960’s, boilers operated at 450°C (840°F) and 4MPa (40 atmospheres). Today’s leading edge combined cycle systems operate at 620°C ...

Oil Measurement in SAGD Steam Generation
The steam injection enhanced oil recovery method used primarily in Alberta, Canada, also known as Steam Assisted Gravity Drainage (SAGD), pushes energy in the form of steam into the formation to liquefy very heavy oil known as bitumen so it can be recovered and lifted to the surface. This method causes the continuous release of water soluble organic material more commonly known as WSO’s ...

Degasification of boiler feed water with Liqui-Cel® membrane contactors
Proper treatment of boiler feed water is an important part of operating and maintaining a boiler system. As steam is produced, dissolved solids become concentrated and form deposits inside the boiler. This leads to poor heat transfer and reduces the efficiency of the boiler. Dissolved gasses such as oxygen and carbon dioxide will react with the metals in the boiler system and lead to boiler ...

Hydroflo diaphragm pumps help reduce boiler corrosion and maintenance costs
ABTCo, located in Alpena, Michigan, is a decorative wood paneling producer using three boilers to generate 7 MW of electricity – half the power needed in the plant plus steam for pulp processing. As in many boiler operations, the main enemy is corrosion, which can destroy system components and lead to boiler failure. Although internal boiler surfaces are protected by a film of magnetic ...

Strainers as an Effective Type of Filter Media
Introduction: When it comes to the separation of suspended contaminants, the best way to initiate the process is with a strainer. The purpose of a strainer is primarily to safeguard downward flowing items, which could be physical items or processes, from the effect of contaminants that clog the flow or disintegrate the passage of the flow. Through the process of elimination, strainers remove ...
