Boiler system pH/phosphate program control method - NALCO

The alkalinity of boiler water should be sufficiently high enough to protect shell and plates against acidic corrosion, but not high enough to produce carryover. A minimum value for alkalinity for adequate protection is 200 PPM. High boiler alkalinity, which is in excess of 700 PPM, should be avoided. Values higher than this can lead to embrittlement of the steel. Phosphates. Phosphates are used to react with …

Is Your Gas Meter Too Small? – JMC – Bay Area Building

consumes 72 Decatherms of natural gas per year for heating and hot water needs, or 72 million BTUs of heat. Now, the calculations To determine the proper size gas line, follow this procedure: First, calculate the distance from the meter to the farthest appliance. In the example below this would be 61 feet (from the gas meter to the dryer).

Water Handbook - Preboiler & Industrial Boiler Corrosion

Aug 22, 1994 · A pH/phosphate program in a boiler water system is controlled by: (1) determining the feed rate of the phosphate to the boiler by adding to a phosphate-feed stream containing the phosphate feeding to the boiler a phosphate-feed tracer in known proportion to the phosphate, determining the concentration of the phosphate-feed tracer in the phosphate-feed stream and correlating the phosphate-feed tracer concentration to the concentration of the phosphate; (2) determining the boiler cycles value

Mar 06, 2012 · Standards are prepared using a phosphate standard solution of 3 mg/L as phosphate (PO4). This is equivalent to a concentration of 1 mg/L as Phosphorus (P). All references to concentrations and results from this point on in this procedure will be expressed as mg/L as P, since this is the convention for reporting results.

5.6 Phosphorus | Monitoring & Assessment | US EPA

Phosphate Control Calcium phosphate is virtually insoluble in boiler water. Even small levels of phosphate can be maintained to ensure the precipitation of calcium phosphate in the bulk boiler water-away from heating surfaces. Therefore, the introduction of phosphate treatment eliminated the problem of calcium carbonate scale.

Mar 25, 2002 · Silicate and phosphate are determined in boiler water at power plants; 60–120 samples h −1 be analyzed. Determination ranges are 0.05–22 mg l −1 for silicate and 0.1–24 mg l −1 for phosphate. Relative standard deviations for metasilicate and orthophosphate were ≤1.2 and 1.3%, respectively.
