ABMA for Water Tube Boilers
Well water can have as high as 1,250 ppm of dissolved solids. 1,000,000 pounds of this water will have 1,250 pounds of solids. A 100 hp boiler vaporizing 3,450 pounds of this as make-up water could leave 4.3 pounds of solids behind. 3.5.4 Suspended solids are insoluble and are measured in Total Suspended Solids (TSS).Get Price
Water Handbook - Preboiler & Industrial Boiler Corrosion
Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.Get Price
