Gestra PK40

BRAND : Gestra

Description

For the safe operation of steam boilers the analysis of boiler water, boiler feedwater and condensate is of great importance. Accurate and true analytical findings require correct sampling methods and properly working analytical instruments. A water sample can be taken from a steam boiler, a steam regenerator, a feedwater tank or a condensate receiver tank. For example, if hot uncooled boiler water is taken from a steam boiler for analytical purposes, the risk of accidents for operating personnel will be higher and errors in the water analysis due to flashing will occur. Some of the uncooled boiler water flashes off as flash steam and, as a consequence, the density of the sample will appear higher and does not represent the true salt content (TDS value) of the boiler water. The increased concentration of non-volatile solids in the sample results in an incorrect water analysis and, consequently, excessive boiler blowdown. The GESTRA sample cooler PK 40 is designed to safely cool down the boiler water sample to a reference temperature of 25 °C. As a result a true sample is obtained and the TDS value, pH value and oxygen content truly corresponds to the boiler water. The PK 40 is supplied as an assembled unit ready for installation. All continuous blowdown valves BA(E)... from GESTRA are equipped with a sampling valve to which the sample cooler PK 40 can be connected
