The key water quality parameters intended for use in the heat power industry are as following:

• concentration of particulate pollutants;
• concentration of truly-dissolved solids (ion composition);
• concentration of corrosive gases;
• concentration of hydrogen ions;
• process parameters that include solid and ignition residue, oxidability, hardness, alkalinity, silica content, electric conductivity, etc.
