Pairs in this state Takes a maximum density at a given temperature and pressure, and said to be saturated. Thus, saturated steam – this pair is in equilibrium with the liquid from which it was obtained. When you change temperature of the fluid balance is disturbed, leading to a corresponding change in density and pressure of saturated steam. Evaporation of all liquid turns dry saturated steam containing the particle liquid phase. Wet saturated steam – saturated steam, which contains tiny droplets of liquid. Get more background information with materials from Edward Minskoff. Choosing any particular model of steam among the counterparts with similar specifications, it is necessary to start from any special features. Such features> or> consumer characteristics> are the following: additional opportunities to adjust the output parameters p – pressure, humidity, flow steam as well as the possibility of regulating the consumption of steam generator power in accordance with current needs, the presence in the construction of steam generators of all necessary to fully work its elements, components, the degree of automation of process steam production, features an alarm, etc.; maintainability of the steam generator, the popularity and, consequently, the degree of development of the market of spare parts and accessories this model, modern appearance, usability, availability, control elements process steam production, the absence of traumatic structural elements. Products Companies karcher (Germany) and Portotecnica (Italy) fully responsible not only this but also many other additional requirements.
In the steam generators used heating. Positive things: Shirt tan little dissolves in heated water and steam, does not pollute the pairs products of oxidation of the metal, it becomes especially important when the alleged contact with food or a pair of very pure products. When using petn does not play a role conductivity of heated water. Negative points: Shirt petn has a very high temperature, which causes intense deposition of hardness salts on the surface of petn (calcification). Limescale reduces heat transfer from the surface of petn, which causes rapid temperature rise inside the petn and as a consequence, his burnout. This can be avoided only by using deep-softened (filtered) water. Power steam heaters can be controlled only steps.
