boiler exam study guide 1. STUDY. Flashcards. Learn. Write. Spell. Test. PLAY. Match. Gravity. Created by. To protect sewer lines from the high temperature and high pressure coming from the boiler blowdown lines, ___. keeping the superheater drain valve open until the boiler is cut in on the line.
Coded tank vented to the atmosphere that protects sewer lines from boiler pressure and high temperature when blowing down. A closed pipe perforated at the top with drain holes on the bottom that remove moisture from the steam. Bending or distortion of boiler or superheater
2019-12-5 · Flush velocity should be greater than system design velocity. After the flush, the condenser hot well, deaerator, and deaerator storage tank are usually cleaned by hand, because these units do not drain completely. Steam blowing normally follows the last boiler
2014-9-21 · The atomizing steam and water supply lines enter the desuperheater pipe at right angles and are welded to both the pipe and the head. A variation of the SA type, the "T" mount style (see Figure V, dotted portion), consists Drain steam line before main steam pressure reducing valve, if used, as well
2019-9-11 · The boiler superheater shown in the illustration is a/an _____. remain open or partially open until steam blows through the lines, and then the valves should be closed If choice D is selected set score to 1. Relieve all fuel oil service pressure to that boiler. o (B) Drain and refill the boiler with cold water. o (C) Open the air
2012-6-28 · Industrial boiler systems can cope with much higher pressures than pressure cookers. These boilers are welded from thick steel plates that are up to 35 mm thick, making pressures of 30 bar and more possible. A stable, robust design is also essential – if a boiler of this type were
2018-2-15 · (c) That valves (D) and (E) in the drain lines from each superheater header lone drain line per header), are open, permitting drainage into the high pressure drain main. It is important to note that impulse steam traps are located in the drain lines to the high pressure drain system, and that these traps should be kept in good working order.
All branches going into the turbine should be reviewed for low points. Main steam piping drains should not be manifolded together with any other drains from the boiler. All drain lines and drain pots, including connections before the turbine stop valve, should have a minimum I.D. of 1 inch. At least one valve in each line should be power operated.
2014-4-17 · Boiler Modification at the Southeast Resource Recovery Facility (SERRF) By steam production and to decrease superheater inlet gas temperature. In addition to tube failures, drain lines at the lower headers of pendants also required replacement. Here the failure mechanism was determined to be caused by erosion.
2019-11-15 · The role of steam distribution lines is to reliably supply steam of the highest reasonable quality to the steam-using equipment. In order for this to be achieved, condensate must be removed quickly and efficiently through steam traps installed in proper
