• The position between the burner joint and the coil is sealed. Adoption of labyrinth type patent technology is made with good seal and large flexible space, which may increase the service life of burner and enhance the heating efficiency. • Triple coil structure is adopted for the boiler with three-pass smok:e and flue, compact design and energy-saving space. The air pre-heater is added to enhance the heating efficiency up to *2% or more. • Multiple running safety protection may ensure the safety and simpl ification of boiler operation with high temperature control precision (± l'C) and good combustible effect. • Adoption of automatic control function is made to increase service life of equipment while save human resources.
