Hot-Water- and Steam-Boiler Water Treatment

2015-9-14 · In steam applications, water quality is an important part of boiler selection. Steam boilers tend to be steel water-tube- or fire-tube-type boilers in the 10-to-1,000-hp range. Fire-tube boilers are more robust and more tolerant of poor water quality, but require more physical space, than water-tube boilers.

2017-6-3 · Returning hot condensate to the boiler makes sense for several reasons. As more condensate is returned, less make-up water is required, saving fuel, makeup wa-ter, and chemicals and treatment costs. Less condensate discharged into a sewer system reduces disposal costs. Return of high purity condensate also reduces energy losses due to boiler

Controlling TDS in the Boiler Water

As with boiler water TDS measurement, conductivity (μS/cm) x 0.7 = TDS in parts per million (at 25°C). Note: the sample of feedwater that is required is from the boiler feedline or from the feedtank and is not a sample of the make-up water supplying the feedtank. The quantity of steam which the boiler generates, usually measured in kg/h.

4 Common Issues in Feedwater Tank Design an

Make up water fed through the top can quickly sink to the bottom of the tank and inlet of the feedwater pump, causing cold untreated water to go directly to the boiler. On/Off make up control can also cause issues. If the make up rate is too great when the feedwater tank calls for water, the feedwater temperature can lower faster than the steam
