introduction of gas fired hot water boiler
Technical Parameter

1. Brief introduction of gas fired hot water boiler :

  • Advanced three pass wet back design:adopts the most sophisticated three returns all wet back structure,thread smoke tube structure, weld joint with high quality.
  • Advanced manufacturing equipment endows Safe and reliable property:adopts corrugated furnace lamps, multi-chain protection. Water level, steam pressure, gas pressure protection. And before leaving factory, all the boiler have been rigorous inspection and testing, including pressure tests and X-ray detection.
  •  Large boiler proper heating area:adopts unique design of a large combustion chamber which increases the radiation heating furnace area, reducing the size of the boiler, reducing the NOX emissions.
  • High efficiency 98%:with threaded pipe and high effective insulation materials and econoizer, increasing the heat transfer and improve boiler thermal efficiency.
  • PLC intelligent controller:boiler control system suitable for high temperature, high humidity environment of long-term operation.
  • High standard: strictly in accordance with Chinese national norms and standards of production, all boiler pressure parts are of high quality steel.
  • High quality accessories: all accessories such as burners, pumps, water level controller, valves and other supporting instruments of international or domestic famous brands.
  • Simple maintenance: the manhole and hand hole is easy for user to maintain.
  • Meet customer’s customized requirement:different designs are available according to customers' specific requirement.
