New Super Mini Boiler

DMH

High efficiency (more than 92%) boiler with the heat pipe type air pre-heater attached.
It is possible to maximize the boiler efficiency by installing economizer depending on customer choice. (Optional)
It is eco-friendly, producing NOx under 40ppm. (optional)
The responsiveness to water quality is high.
Its installation space is rather small compared to that of conventional flue smoke tube type boiler.

  • Fuel consumption was based on the net heating value.
      (Light Oil : 10,300 kcal/㎏, LNG: 11,000 / 10,000 kcal/N㎥, LPG + AIR: 15,400 / 14,500 kcal/N㎥, Propane: 24,350 / 22,400 kcal/N㎥, Butane: 31,840 / 29,500 kcal/N㎥)
  • Supply gas pressure was based on the inter-stage pressure (2,000 ~ 4,000 mmAq)
  • Gas diameter in parentheses ( ) was based on low-pressure. (200mmAq)
  • Calorie generation was based on the steam pressure of 10kg/㎠, steam enthalpy of 663.7 kcal/kg, and feed water temperature of 20℃.
  • Boiler efficiency is under rated load based on the net heating value.
  • Boiler efficiency and calories can be reduced depending on site conditions as well as measurement error.
  • The above specification table can be unexpectedly changed in order to improve performance.
