Waterboiler system with solids removal apparatus

摘要

A water boiler system for producing steam or hot water includes an apparatus for removing dissolved minerals from boiler water without the use of water softeners or other chemical agents. An electromagnetic flux producing device (54) first treats the boiler water with alternating electromagnetic flux to cause nucleation of dissolved minerals in the water, rather than on boiler surfaces, with nucleated particles accumulating into particulates which settle by gravity to the bottom of the boiler (12). Boiler water is then drained from the bottom of the boiler (12) and fed by pump (56) to a mechanical separator (58) which separates solids and passes cleansed boiler water back to the boiler (12). The cleansed boiler water may be directed at high velocity toward the bottom of the boiler (12) to stir the boiler water to inhibit compact settling of the precipitated particulates and/or to enhance the heat transfer efficiency of the boiler (12).
