Multi-boiler installations. The piping arrangement for multi-boiler installations is covered in the UK HSE Guidance Note (PM60); the following points are made: Operation. Only one boiler can be blown down at any one time. In fact, sizing of the blowdown vessel will be based on the highest pressure boiler with the biggest blowdown line size.
What is Boiler Blowdown? Blowdown occurs when water is removed from a steam boiler while the boiler is operating. Boilers are "blown down" to remove suspended solids and bottom sludge from steam boilers. Removal of suspended solids helps insure the boiler generates high quality steam. It also prevents foaming at the water surface which can 
The boiler should be brought-up slowly and the expansion movement should be monitored. When the drum pressure reaches the pressure value of 5kg/cm2(g), the first blowing can be started. Fuel feeding is discontinued and the blow-off valve is opened to blow through the superheaters, main steam line and out of the temporary blow off piping.
Blow Down Tanks. Wendland blow down tanks are fabricated with 3/8" thick heads and shell and are inspected and stamped in accordance with the latest ASME code specifications, under Section VIII, Division 1 for 150 psi design pressure at 300° F. They are also registered with the National Board of Boiler and Pressure Vessel Inspectors.
The bottom blow down is done at least daily (more often depending on boiler water conditions) to blow out scale and mud from the bottom of the boiler. If possible you should lower the firing rate of your boiler when you do the bottom blow down then return to normal firing rate after the blow down. Question 11.
Never blow down a furnace wall header while the boiler is operating. The boiler waterside should be inspected on a regular basis. If there are any signs of scaling or buildup of solids on the tubes, water treatment adjustments should be made. The boiler might require either a mechanical or chemical cleaning.
The blow down valves are needle valves designed for operation in open position. Their function is mainly to control a continuous flow of steam and/or water under high differential pressure. For
Leave Boiler TURNED OFF for 15 minutes to allow for EVEN Heating and Expansion of Boiler Internals. AFTER 15 minutes RE-START the Boiler in MANUAL and LOW-FIRE. Perform a Blow-down of the Boiler Sight Glass. SLOWLY Open the Sight Glass Blow-down Valve #8. Upon completion of Sight Glass blow-down OBSERVE how quickly the Sight Glass refills.
Use proper water treatment to prevent the buildup of scale on the boiler. After scale has built up on the walls of the boiler it is almost impossible to remove it from the boiler. The introduction of acids in the pressure vessel is thoroughly discouraged, since virtually any solution that will chemically attack the scale will also attack the boiler metal.
