WebMar 3, 2016 · Surface blowdown removes dissolved solids that accumulate near the boiler liquid surface and is often a continuous process. Suspended and dissolved solids can also form sludge. Sludge must be removed because it reduces the heat-transfer capabilities of the boiler, resulting in poor fuel-to-steam efficiency and possible pressure vessel damage. WebThe length of the blowdown line between the boiler and the blowdown vessel. In practice, a reasonable minimum length of blowdown line is 7.5 m, and most blowdown vessels are sized on this basis. Blowdown lines will contain bends, check valves and the blowdown valve itself; and these fittings will increase the pressure drop along the blowdown line.

WebJul 5, 2024 · The primary purpose of blowdown is to maintain the solids content of boiler water within certain limits.This may be required for specific reasons, such as contamination of the boiler water. In this case, a high blowdown rate is required to eliminate the contaminants as rapidly as possible. WebControls boiler total dissolved solids (TDS) using conductivity measurement and automatic surface blowdown via intermittent sampling. Adjustable interval timer (1/4 – 3 hours) periodically opens an electric valve to sample boiler water conductivity. If the sample is below the micromhos set point on the potentiometer, blowdown is not required ... WebSurface or skimming blowdown is designed to remove the dissolved solids that concentrate near the liquid surface. Surface blowdown is often a continuous process. Insufficient blowdown may lead to carryover of boiler water into the steam, or the formation of deposits. Excessive blowdown will waste energy, water, and chemicals. friends abreast
