Boiler Heating Systems Buyer Guide (Types, Top Brands

Whats a condensing boiler and how is it different from a non-condensing one? Any type of boiler can be a condensing boiler. The characteristic that sets condensing boilers apart from non-condensing ones is theyre designed to recover heat (in water vapour) that would otherwise escape through the flue.

Hard water - Wikipedia

Hard water is water that has high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates.. Hard drinking water may have moderate health benefits. It can pose critical problems in industrial settings, where water hardness is

Creating Flame Colors - The Science Company

Some metals will burn with a characteristic flame color. To perform a flame test a powdered sample of chemical (see list below) is placed onto a platinum or Nichrome wire loop and suspended in a Bunsen burner (or propane torch) flame. It is important to first clean the wire loop in the flame so no contaminating dust interferes with the true

Water Handbook - Cooling System Microbiological Control | SUEZ

Microbes and hydrated biopolymers contain large amounts of water, and biofilms can be over 90% water by weight. As a result, biofilms have thermal conductivities very close to that of water and, in terms of heat transfer efficiency, a biofilm is the equivalent of a layer of stagnant water

Acid mine drainage - Wikipedia

Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks

Hyperthermia - Wikipedia

Hyperthermia, also known simply as overheating, is a condition where an individual's body temperature is elevated beyond normal due to failed thermoregulation.The person's body produces or absorbs more heat than it dissipates. When extreme temperature elevation occurs, it becomes a medical emergency requiring immediate treatment to prevent disability or death.

Water Hardness - an overview | ScienceDirect Topics

Water hardness is handled a little differently from salinity in that in some countries the degree is the unit of measure. One German degree of hardness equals 10mg/liter (ppm) of calcium and magnesium oxide or 17.8ppm of CaCO 3 in the USA. This is not at all equivalent to salinity in that a relatively low salinity water rich in calcium and magnesium could have a relatively high degree of hardness.
