Bottom blow down valves: They provide a means for removing solid particulates that condense and lay on the bottom of a boiler. As the name implies, this valve is usually located directly on the bottom of the boiler, and is occasionally opened to use the pressure in the boiler to push these particulates out.
Surface blow down line: It provides a means for removing foam or other lightweight non- condensible substances that tend to float on top of the water inside the boiler.
