The 3-passes design packaged boilers are most suitable to the burn fuels like heavy/light oils & Gasses. The high combustion volume along with large water and Steam holding capacity makes it the most boilers in its classes.
Advantages and Benefits:
High Efficiency of 88 % on NCV saves running costs to the Boiler (Savemax ? Oil/Gas Fired Boilers).
Large convective heating surface in the 2nd & 3rd pass tubes ensures excellent heat transfer
Big water holding & steam holding space gives to quick response to fluctuating steam demands.
Massive large heat transfer surface reduces the thermal stresses on the boiler surfaces.
Dry steam reduces the processing time, saved the steam & improved quality of processed goods
Horizontal packaged boilers ? less site work & quick commissioning
