    If an economical blowdown rate is to be maintained, suitable boiler water tests must be run frequently to check concentrations in the boiler water. When sodium zeolite softened makeup is used, the need for boiler blowdown is usually determined by measurement of the boiler water conductivity, which provides an indirect measure of the boiler Get Price

    boiler water, calcium will preferentially precipitate as the phosphate before pre-cipitating as the carbonate, and calcium phosphate becomes the most prominent feature of the deposit. At the high temperatures found in a boiler, deposits are a serious problem, causing poor heat transfer and a potential for boiler tube failure. In low-pressureGet Price

  • Pressurised Deaerators | Spirax Sarco

    A cost saving can be achieved with respect to chemicals - this argument becomes increasingly valid on large water-tube type boilers where flowrates are high, and low TDS levels (< 1 000 ppm) need to be maintained in the boiler feedwater. Chemicals added to control the oxygen content of the boiler water will themselves require blowing down.Get Price
