  1. Blowdown is an internationally broadcast documentary television series that follows a team of explosive demolition experts as they prepare and implode iconic, complex and challenging structures around the world.
  2. or Cylinder Blowdown: Blowdown occurs during the period between exhaust valve opening and BDC. It is the period (measured in crank degrees) during which residual exhaust gases are expelled from the engine before the exhaust stroke begins. ...
  3. A tree or shrub that has fallen across the Trail. Maintainers (see Maintainer) have dozens of words to describe each kind of fallen tree.
  4. The continuous or intermittent discharge, or purging, of a small amount of circulating water to maintain an acceptable concentration of dissolved solids in the water.

  6. trees or whatnot "blown down" by wind and now blocking the trail.
  7. Condensate and gas is produced simultaneously from the outset of production
  8. A final phase of production from some oil reservoirs that have significant volumes of gas forming a 'cap' which overlies the oil column. ...
  9. The use of air or an inert gas pressure to displace a liquid out of a filter cake. Continued blowdown is used to dry the cake in situations.
  10. The process of opening a valve, normally in the lower regions of a boiler, which expels water but also dissolved and suspended solids in that water. A way of reducing the TDS/pH.
  11. A generic engineering term which can be used as noun or verb. A cleaning and/or venting process. Some specific applications: (1) A process for cleaning water-sides of a boiler. A top blow removes scum and floating contaminants, a bottom blow removes sludge. (2) To backflush and clean a SEACHEST. ...
  12. Trees felled at the base by high winds.
  13. uprooting by the wind. Also refers to a tree or trees so uprooted. (BC MoF Web Site Glossary) return to top
  14. From time to time natural gas pipelines and other facilities must be depressurized for maintenance or inspection purposes. During depressurization natural gas may be released to atmosphere in a controlled manner from a designated vent point to ensure the pipeline is safely depressurized. ...
  15. The removal of water from an evaporative system (e.g., cooling tower or boiler) to reduce mineral concentration that can cause scaling.
  16. The water drawn from boiler systems and cold water basins of cooling towers to prevent the buildup of solids.
  17. Trees tipped over or uprooted by high winds. An obstacle commonly encountered on portages and a major impediment to cross country bushwhacking. Now, in the aftermath of the Independence Day windstorms of 1999, a major fire risk over large portions of the BWCA. Also known as windfall.

  19. a downed tree. Usually a downed tree that crosses a trail or river.
  20. Partial venting or draining, under pressure, of the water side of a boiler to reduce or remove unwanted contaminants. Also the pressure drops after releasing a pressure-relief valve.
  21. a shoreline tree that has fallen into the water; also known as a "laydown"
  22. When the tent is destroyed by high winds or a storm.
  23. When boiler water is removed from the boiler, this water is called the “blowdown”. Blowdown is usually removed to maintain the desired concentration levels of suspended and dissolved solids, and also to remove any sludge.
  24. The drain connection including the pipe and the valve at the lowest practical part of a boiler, or at the normal water level in the case of a surface blowdown. The amount of water blown down. ...
  25. A method of producing a gas/condensate reservoir by letting the reservoir depressure over time without re-injecting any gas. With this method of production some condensate may condense within the reservoir, where its recovery is no longer a practical proposition.
