Product Description

Gas Condensing Boiler description icon

Fangkuai has introduced a line of gas-fired condensing boilers that employ a closed condensate recovery system to recycle high-temperature condensate directly back into the boiler. This, combined with a three-pass structure, economizer, and air preheater, maximizes the utilization of the flue gas heat. The sensible heat and latent heat in the flue gas heat are combined to recover and utilize the heat of high-temperature condensate water from the source, which can not only save fuel costs and operating costs but also improve the overall operating efficiency of the boiler, killing two birds with one stone.

Product Advantages

Gas Condensing Boiler advantages icon
  • low running cost

    The gas-fired condensing boiler is equipped with a closed condensate recovery system that recovers over 70% of the condensate, resulting in reduced operating costs.

  • long lasting

    Additionally, the corrugated furnace not only increases the heating surface area but also minimizes combustion chamber loss caused by thermal expansion and contraction, thereby extending the service life of the boiler.

  • deep coupling

    The combustion and heat exchange processes are closely coupled, turning the boiler into a complete thermal energy system that enhances efficiency.

  • Boiler room infrastructure cost is low

    Despite its compact size, the condensing gas boiler can be installed underground, semi-underground, or on the ground, making it a suitable option for various boiler rooms.

Technical Features

  • Wing Heat Exchange Technology

    Innovative "feather tube" heat exchange technology replaces the outer finned tube, which eliminates scaling and cleaning difficulties associated with the latter. The same volume of the feather tube significantly increases the heat exchange area by five times, effectively absorbing the latent heat of vaporization in flue gas and boosting efficiency.

  • Empty pre-integrated structure

    Furthermore, the gas-fired condensing boiler employs air and flue gas convection for heat exchange, enhancing the absorption of the flue gas's latent heat. The heated air, facilitated by the air preheater, is sent to the burner through connecting pipes, providing warm air for combustion and improving combustion efficiency. With a frequency-controlled fan, the combustion can be adjusted with greater precision, allowing the boiler to operate smoothly under diverse working conditions.
