• 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 92% 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.
