DESIGN SOFTENER FEEDWATER TO PRODUCE STEAM

U ovome radu obrađena je problematika pripreme sirove napojne vode za proizvodnju pare. Sirova voda sadrži mehaničke nečistoće, rastvorene soli i plinove te se kao takova nikada ne koristi za napojnu vodu kotla prije nego se provedu svi postupci pročišćavanja kako bi se osigurala ekonomična proizvodnja tehnički čiste vodene pare. U ovome radu opisani su tehnološki postupci koji se koriste za postizanje propisane kvalitete sirove napojne vode. Posljedica neadekvatno pripremljene sirove napojne vode jest pojava korozije, kamenca i mulja koji otežavaju normalan rad termoenergetskih postrojenja, smanjuju vijek trajanja, puzdanost te uvelike utiču na ekonomičnost i sigurnost termoenergetskih postrojenja . U ovome radu opisani su najučestalije oblike korozije koji nastaju u termoenergetskim postrojenjima te mjere zaštite metala od kemijske i elektrokemijske korozije.This papers explains the way we solved the preparation of raw feed water used for producing steam.Natural raw water contains all sorts of mechanical impurities, solute salts and gases so as such, it is never used as a boiler feed water before all purification processes haven't been conducted, in order to ensure the economical production of technically pure water steam. This papers describes the technological processes used for achieving regulatory quality of raw feed water. The consequences of inadequately prepared raw feed water are corrosion occurrence, lime scale and mud, which impede normal activities of thermal energy plants, reduce their lifetime and reliability and massively affect the cost-effectiveness and safety of thermal energy plants. This papers describes the most common forms of corrosion which occur in thermal energy plants and ways to protect metal from chemical and electrochemical corrosion
