T/ZZB 1777-2020 Fully submerged high voltage electrode hot water boiler
Basic Information
Scope
Main technical content: This standard specifies the terms and definitions, models and basic parameters, basic requirements, technical requirements, test methods, inspection rules, painting, packaging, marking, and accompanying documents, quality commitments, etc. of fully immersed high-voltage electrode hot water boilers. This standard applies to fully immersed high-voltage electrode hot water boilers (hereinafter referred to as boilers) that directly use high voltage (voltage levels of 6.3 kV, 10.0 kV, 13.5 kV, and 20.0 kV) as power sources, and use solutions of sodium phosphate, sodium hydroxide, or sodium sulfate dissolved in pure water as electrolyte solutions for conduction. The rated pressure is not more than 1.6 MPa, and the boilers can simultaneously or separately produce hot water required for living, production, and service industries.
