Oil/gas fired steam boiler
The large-volume flame tube and the smoke tube bundle are perfectly matched to one another. The boiler is characterized by a very compact construction. The flame tube, internal water-flushed rear flue gas reversing chamber, first smoke tube and second smoke tube are all arranged for optimum flow within the cylindrical pressure vessel.

Product introduction

Overview:

The large-volume flame tube and the smoke tube bundle are perfectly matched to one another. The boiler is characterized by a very compact construction. The flame tube, internal water-flushed rear flue gas reversing chamber, first smoke tube and second smoke tube are all arranged for optimum flow within the cylindrical pressure vessel. In interplay with one another, the radiant and convection heating surfaces promote rapid water circulation, thereby accelerating the passage of steam bubbles to the steam chamber. The heat supplied by the fuel is converted into steam quickly and with no material stress due to an even transfer of heat. The large water chamber offers sufficient storage volume to be able to accommodate sudden peaks in demand.

Benefit:

Control system: automatic control, PLC system

Burner: adopting of world top grade brand burner to ensure the boiler heating efficiency and improve boiler quality

100% corrugated furnace: provides large space for combustion and excellent heating flexibility

Wet-back: design as 100% of water cover fire concept, enhance the heat efficiency

Accessories and electric control: mounted with all necessary accessories and electric control system, then tested in house, for making the boiler installation job the most convenience

Construction:

Three pass fire chamber. The flame tube (first pass) and two smoke tube bundles (second and third pass) are integrated in an ideal manner into the pressure vessel together with the water-flushed rear reversing chamber. The laterally positioned flame tube and the horizontal rear and vertical front heating gas reversal produce a large radiant and convection heating surface with a large steam chamber, but the external dimensions remain small. The floors are anchored stably by the large continuous flame tube and they are ingeniously connected with the boiler shell using gusset stays for even load distribution.

We can also produce water tube structure boiler for bigger evaporation requirement.
