Structural features

※ Compact structure, attractive appearance.
※ Increases exit gas temperature of boiler, reduces dew corrosion during low-load operation.
※ Increase length of furnace pipe, reduces outlet gas temperature of furnace, improves tube plate environment in rotary combustion chamber.
※ Rational use of corrugated furnace and strengthened heat transfer element thread.
※ Compact structure, save floor area.
※ Large heat transfer temperature difference, good heat transfer performance.
※ High efficiency, small resistance of smoke.
※ Adopts ND steel (09CrCuSb), thus has good corrosion resistance and long service life.
※ Adopts reasonable flue structure.
※ Reduces flow resistance of working medium in economizer and condenser.
