  • Getting to the Bottom of the Boiler Blowdown Procedure

    Nov 08, 2016 · Most boilers have a bottom drain line with two different valves: a knife valve and a gate valve. The optimum way to blowdown a boiler is to begin with the valves fully closed. Start by opening the knife valve, then open and close the gate valve. This should be done to both back and front valves if the boiler comes equipped.Learn More

  • Steam Boiler Blowdowns: Continuous Blowdown VS Manual

    Jul 19, 2016 · The purpose of boiler blowdown is to control solids in the boiler water. Blowdown protects boiler surfaces from severe scaling or corrosion problems that can result otherwise. There are two types of boiler blowdowns: ''continuous'' and ''manual''. Continuous blowdowns use a calibrated valve and a blowdown tap near the boiler water surface.Learn More

  • Boiler Blowdown Frequency

    The most common recommendation for the frequency of bottom blowdown of a steam boiler is at least once every 8 hour shift. However this guideline is dependent upon the boiler operating conditions and water quality. A local chemical expert is the best resource for developing the required blowdown rate and frequency to maintain proper water quality.Learn More
