8/11/2016 · The boiler blowdown procedure is the purposeful discharge of water from the boiler. This practice works to avoid the build-up of concentrated impurities inside of the system. These byproducts and impurities are the result of the continual evaporation of steam. While
28/3/2019 · Blowdown piping should be at least the same size as the blowdown tapping on the boiler. Blowdown valves should be sized in accordance with the ASME Code and piped to a safe point of discharge. There should be either two slow opening valves or one quick opening valve and one slow opening valve piped to a series.

Various factors affect blowdown. They include type of boiler, operating pressure, water treatment and amount and quality of makeup water. Blowdown piping should be at least the same size as the blowdown tapping on the boiler. Blowdown valves should be sized according to ASME code and piped …
Considering these two factors, blowdown water for a Clayton Steam Generator typically has a concentration of 24,000 to 40,000 ppm. This is comparable to typical values for conventional boilers in the range of 2,500 to 3,500 ppm. Since our blowdown water has TDS concentrations that are 7 to 16 times higher than conventional boilers, the volume

The energy contained in the water being blown down is the liquid enthalpy of water at saturation temperature at boiler pressure. In Example 3.14.1, the boiler pressure is 10 bar g, and from steam tables, hf is 782 kJ/kg. So the rate at which energy is being released from the boiler …
The bottom drain line on your boiler usually has two valves: a gate valve and a knife valve. The proper way to bottom blowdown a boiler is to start with both valves fully closed. Start by opening the knife valve, then completely open and then close the gate valve. Do this to both front and back drain valves if your boiler is so equipped.
