Introduction
Vacuum Hot Water Boiler
Vacuum hot water boiler, adopts principle of water-fire tube boiler, SU304S stainless steel heat exchanger, high heat transfer efficiency of flue gas, compact structure, high efficiency and energy saving, ultra low NOx emission and small volume. The vacuum boiler operates under negative pressure and has multiple protection functions, It is safe and reliable and never explodes. It has exquisite appearance, convenient installation, convenient maintenance and no need for supervision.
Core Technology:
1. Automatic packaged boiler, Independently research and develop PLC control system, intelligent matching, rich functions, safe and convenient. Automatic control of boiler water level, over-high,over-low water level and over-pressure alarm function, adding the fifth water level protection.
2. High efficiency up to 99.8% and energy saving, three pass structure extend the flow of smoke and enhance the heat transfer; Big size corrugated furnace area for heating, improve the boiler effiency; Whole adopt corrugated tubes, strengthening heat transfer and eliminating welding stress.
3. 100% safety, Whole wet back structure and transition multi-loop full-temperature condenser design, ND steel material, fin tube design, which highly reduces the back plate sheet temperature(around 50°C); Flame-out protection, power failure self-locking protection function; Two water level gauges and two Spring Safety Valve, Backup protection.
4. Innovative design , Boiler operation data query and automatic fault identification function, data collection, analysis, storage and remote monitoring of the Internet.
