Boiler

(english) A closed vessel in which water, is transformed into steam at a given pressure and temperature under controlled conditions.

Zirconia

(english) ZrO2 an acid refractory up to 2500 B0C (4532 B0F) having good thermal shock resistance and low electrical resistively.

Change management

(Software Engineering) a set of software engineering actions that helps ensure that changes are properly identified, controlled, and reportedChange report

Secondary treatment

(Environmental Engineering) In wastewater treatment, the conversion of the suspended, colloidal and dissolved organics remaining after primary treatment into a microbial mass with is then removed in a second sedimentation process. Secondary treatment included both the biological process and the associated sedimentation process.

Basic Oxygen Furnace (BOF)

(english) "WHAT A pear-shaped furnace, lined with refractory bricks, that refines molten iron from the blast furnace and scrap into steel. Up to 30% of the charge into the BOF can be scrap, with hot metal accounting for the rest. WHY BOFs, which can refine a heat (batch) of steel in less than 45 minutes, replaced open-hearth furnaces in the 1950s; the latter required five to six hours to process the metal. The BOF's rapid operation, lower cost and ease of control give it a distinct advantage over previous methods. HOW Scrap is dumped into the furnace vessel, followed by the hot metal from the blast furnace. A lance is lowered from above, through which blows a high-pressure stream of oxygen to cause chemical reactions that separate impurities as fumes or slag. Once refined, the liquid steel and slag are poured into separate containers. "

Boring Tool

(english) A cutting tool in which the tool bit,the boring bar and in some cases the tool holder are incorporated.

In situ treatment

(Environmental Engineering) Treatment of a waste in place, as opposed to pumping or digging the waste up and then treating it.

Change control

(Software Engineering) an umbrella process that enables a project team to accept, evaluate, and act on changes in a systematic manner

Acetyl Tributyl Citrate

(english) One of the lubricating oils generally applied on tin Mill Products (tin plate, TFS-chrome/chrome oxide coated steel, and blackplate).

Structured programming

(Software Engineering) a design method that limited design constructs to only three basic forms and constrains program flow for better quality

Hydrogenesis

(Concrete Engineering) Another term for condensation. The term is especially applied to base and soil substrates under highway pavements. where the barometric pump causes the inhalation of humid air, which then condenses in those structures, causing an ever increasing moisture content and sometimes instability.
