All boilers, regardless of their design, require some degree of feedwater pretreatment. This pretreatment process addresses the three specific areas: water hardness, Total dissolved solids and alkalinity levels. Since we discussed water hardness and TDS in previous boiler tips we felt is was time to address alkalinity. Acceptable Levels of Alkalinity Alkalinity, like hardness and TDS, is expressed as parts per million (ppm). The acceptable level of alkalinity in a boiler depends largely upon the pressure that the boiler will be operating at. In a low pressure boiler, this level should not exceed 700 ppm. If the alkalinity level exceeds 700 ppm it may result in a breakdown of the bicarbonate producing carbonate and liberate free carbon dioxide with the steam. This presence of carbon dioxide will corrode steam and return lines. THE MAXIMUM ALLOWABLE CONCENTRATION OF ALKALINITY WITHIN A LOW PRESSURE BOILER IS 700 PPM.

Get Ready! The time is fast approaching when you will need to have your boilers back on-line. Yes, winter is coming and so are the demands placed upon your boilers. To make sure you are operating safely and at peak efficiency we recommend that you, or a qualified boiler service technician, open your boiler for an inspection. Clean both the fireside and waterside. If you haven't had your boiler inspector out, call him so that he can take a look. When you reassemble your boiler use new gaskets. Also clean and inspect your low water cutoff. Check all safety devices, including a pop test on the safety relief valves, flame safeguard checks and a leak test on safety shut-off valves.
Buying a packaged boiler is kind of like buying a new car. You need something that will get the job done within a given price range. There are some features that you must have and others that you would like to include if it fits that budget. Style counts for a lot in the purchase of a car; not a real critical factor in the boiler world. Whether your boiler is to be used for process duty or for heating purposes there are some basic points that you must consider. This listing was adapted from HVAC Systems and Components Handbook edited by Nils R. Grimm and Robert C. Rosaler. (McGraw-Hill Companies, 1998).
Sizing and capacities of the Voyager® O-style boiler are available from 10,000 PPH up to 500,000 PPH of steam flow, well suited for high pressure superheated steam, when needed. Larger field-erected solutions are also available. If you're looking for a high performance soultion that's engineered for the long run, this boiler has your name on it; Voyager.
