Reverse Osmosis Improves Boiler Efficiency – Water Technology …

16/1/2017 · A typical industrial boiler producing steam at the rate of 37,000 pounds per hour with 50% condensate return, has a makeup demand of 19,500 pounds per hour (approximately 40 gallons per minute). In our example, this produces a boiler feedwater having a conductivity of 200 micromhos/cm.

Finding the Root Cause of Boiler Tube Failures

Identifying and correcting the root cause of tube failures is essential to help lessen the chance of future problems. Symptoms: Intergranular micro-cracking.Loss of ductility or embrittlement of the tube material leading to brittle catastrophic rupture. Causes: Most commonly associated with excessive deposition on ID tube surfaces, coupled with a boiler water low pH excursion.

Tube Failures in High Pressure Boilers - Bright Hub Engineering

4/5/2009 · Tube failures are classified as in-service failures in boilers. These failures can be grouped under six major causes: Stress rupture. Fatigue. Water side corrosion. Erosion. Fire side corrosion (Called also as High temperature Corrosion) Lack of quality control. These lead to twenty-two primary causes that can cause a tube failure in a high

Conductivity Measurements for Boiler Blowdown | Yokogawa …

The most common methodologies used for boiler blowdown control include: (1) continuous, (2) manual and (3) automatic. Continuous blowdown utilizes a calibrated valve and a blowdown tap near the boiler water surface. As the name implies, it continuously takes water from the top of the boiler at a predetermined rate to reduce the level of
