1. Priming - This is the ejection of boiler water into the steam take-off and is generally due to one or more of the following: -Operating the boiler with too high a water level. -Operating the boiler below its design pressure; this increases the volume and the velocity of the steam released from the water surface.

Boiler Water Quality

As a rule of thumb, about 1000 ppm can be considered a safe maximum. A hard water containing 200 ppm in the feedwater would tolerate five concentrations in the boiler (200 times 5 = 1000). On the other hand, a soft water with 25 ppm could be concentrated 40 times before reaching the critical point (40 times 25 = 1000).

The ratio of chlorides in the boiler water to that of the feed water can be used as a means to determine the amount of blowdown required. The chloride test is unsuitable for feedwater with low incoming concentrations and the concentrations in the feedwater must be averaged over time for accuracy. High boiler solids will lead to foaming, priming

For example, if a boiler operated at 150 psig (1.03 MPa) uses feedwater of suitable quality for use in a 1001-1500 psig (6.9-10.34 MPa) boiler, then the boiler water limits and chemical treatment program should be based on the higher pres sure guidelines.

Ø Do NOT refill a boiler while it is hot. Treated warm water should be used. The boiler should be vented to permit air to escape. Ø Check the water level in the gauge glass (mid point) and all the gauge glass valves are open. Ø Test true water level by opening the test cocks, starting with the uppermost. Ø Open all the feed water supply valves.
