In this process, a liquid desiccant dehydrator serves to absorb water vapor from the gas stream. Glycol, the principal agent in this process, has a chemical affinity for water. This means that, when in contact with a stream of natural gas that contains water, glycol will serve to 'steal' the water …

The make-up water is usually natural water either in its raw state, or treated by some process before use. Feed-water compositiontherefore depends on the quality of the make-up water and the amount of condensate returned to the boiler. The steam, which escapes from the boiler, frequently contains liquid droplets and gases.

If bottled water is not available, bring water to a full rolling boil for 1 minute (at elevations above 6,500 feet, boil for 3 minutes). After boiling, allow the water to cool before use. Boil tap water even if it is filtered (for example, by a home water filter or a pitcher that filters water).

Common Boiler Feedwater Treatment Issues and How to Avoid …

Aug 29, 2017 · Economizer, water wall panel and evaporator are to be filled before boiler light up started. We all known about very well that water is pumped into the boiler steam drum with the help of B.F.P (Boiler Feed Pump). This pump take the water from the Deaerator and reaches the water into drum through economizer, water wall and evaporator.

How to Destroy a Boiler -- Part 3

The feedwater (make-up water) from outside needs to be treated for the reduction or removal of impurities by first filtration, and then followed by softening, evaporation, deariation, ion exchange etc. Internal treatment is also required for the conditioning of impurities within the boiler system, to control corrosion, as reactions occur in the boiler itself and the steam pipelines.

The ideal regenerative Rankine cycle

A considerable percentage of the total energy input is used to heat the high pressure water from T 2 to its saturation (point a). Figure.2. Rankine cycle. To reduce this energy, the water could be preheated before it enters the boiler by intercepting some of the stream as it expands in the turbine and mixing it with the water as it exits the

Economizer - an overview | ScienceDirect Topics

Colin French CEng, FlnstE, FBIMgt, in Plant Engineer's Reference Book (Second Edition), 2002. 31.1 Introduction. Economizers for boilers have been available for nearly 150 years, almost as long as boilers themselves. For modern shell boilers, high efficiencies have made it increasingly difficult to justify the use of an economizer, the final decision being based in terms of payback period

Best Boiler Buying Guide - Consumer Reports

Jun 23, 2020 · A condensing boiler concentrates water vapor produced in the heating process, and uses waste heat to preheat cold water entering the boiler. Condensing boilers are extremely energy efficient

Heating Systems Flow Rates - Engineering ToolBox

The volumetric flow rate in a heating system can be expressed as. q = h / (cp ρ dt) (1) where. q = volumetric flow rate (m3/s) h = heat flow rate (kJ/s, kW) cp = specific heat (kJ/kgoC) ρ = density (kg/m3) dt = temperature difference (oC) This generic equation can be modified for the actual units - SI or imperial - and the liquids in use.

Water Hardness - Washington University in St. Louis

As scale builds up, water flow is impeded, and hence appliance parts and pipes must be replaced more often than if Ca 2+ and Mg 2+ ions were not present in the water. Some Strategies to "Soften" Hard Water. For large-scale municipal operations, a process known as the "lime-soda process" is used to remove Ca 2+ and Mg 2+ from the water supply

Step-by-step: a Glimpse into the Dry-docking Process

Apr 18, 2016 · Pumping Down the Dock and Vessel "Taking" the Blocks. The water is drained from the dry-dock (generally overnight) over the course of about eight to ten hours, depending on the size of the vessel. Before the vessel is rested on the block, specialized dive teams ensure the block structures are in the correct location.

Basics of Industrial Boiler Water Treatment | Powerhouse

Sep 26, 2016 · At this point in the boiler feed water treatment process, any condensate being returned to the system will mix with the treated makeup water and enter the deaeration or degasification process. Any amount of gasses such as oxygen and carbon dioxide can be extremely corrosive to boiler equipment and piping when they attach to them, forming oxides and causing rust.
