| titleOfInvention | The method of operation of steam boiler |
| abstract | The method of operation of the steam boiler of the present invention is while the incrustation scale in suppression steam boiler generates, and the COD of boiler water suppresses one of environmental standard for discharge water be i.e. not more than 30mg/L.To utilize demineralized water treatment device (52) is no more than 5mg CaCO by Hardness Control 3 The water supply of/L is by being fed to steam boiler (20) for water passage (41), and from the discarded part boiler water of vent pathway (26), heating boiler water in steam boiler (20), generates steam simultaneously.And, from pharmaceutical supply device (60) to supply of supplying water containing alkali silicate, alkali metal hydroxide and the medicament aqueous solution of the ethylenediaminetetraacetic acid as scale inhibitor, the concentration making scale inhibitor is at least 1.5 molar equivalents times for hardness of water.Concentration rate, by being controlled by the discarded of boiler water from vent pathway (26), is controlled to be not more than the degree of 40mg EDTA/L for the concentration of scale inhibitor by boiler water. |
