HFO Generator Set Exhaust Gas Boiler, 6.5T Heat Recovery Steam Boiler for Power Generation

Description of HFO Generator Set Waste Heat Recovery Boiler:

Exhaust gas heat recovery system after engines for purpose of superheated steam generation for combined cycle application and saturated LP steam generation for Power plant’s self-demand use.

The system of HFO Generator Set Waste Heat Recovery Boiler :

The exhaust gas boiler system is composed of flue gas system, exhaust gas boiler body and boiler local control device and related auxiliary equipment.

Flue gas system

The exhaust gas boiler exhaust gas system consists of an inlet flue system and an outlet flue system. Under the maximum continuous evaporation, the actual exhaust back pressure of the flue gas system is less than the exhaust back pressure of the HFO generator set.

The Inlet exhaust gas box of the exhaust gas boiler

It is used to introduce the generator set exhaust gas into the exhaust gas boiler, which ensures a good and even distribution of the internal exhaust gas.

The inlet flue system of the exhaust gas boiler is composed of inlet high temperature expansion joints and inlet exhaust gas box.

The high temperature expansion joint is a 304 stainless steel metal expansion joint, which is designed with external insulation. The outer casing is made of silicone rubber soft joint and fixed by flanges at both ends.

All of the above gas ducts are constructed with an external thermal insulation. See above for details.

Outlet flue system of exhaust gas boiler:

It consists of a low temperature expansion joint (non-metal, no insulation layer), an outlet flue and an outlet chimney.

There is a manhole in the necessary position of the flue gas system to meet the entry of personnel during equipment inspection and maintenance.

H Fin tube-main heat exchange tubes in waste heat boiler:

Description of H-fin boiler tubes

The heat transfer tube of the boiler adopts the H-shaped fin tubes, it is to weld two pieces of steel with arcs in the middle of the arc symmetrically onto the raw tube to form the fins (ribs), the front shape is quite like the letter "H", so it is called H-finned tube. The fins of the H-finned tube are rectangular, approximately square, with a length of about 2 times the diameter of the tube and an extended heating surface. H-finned tube can also be made into "double H" finned tube of double-tube, with good rigidity structure, it can be applied to the longer row of the tubes.

Advantages of H-finned tube:

The H-finned tube is the main heat exchange component in the whole exhaust gas boiler, and the H finned tube has the following advantages.

(1) Excellent wear resistance

(2) Fouling reduced

(3) Reduce the resistance of exhaust gas

(4) Fins and steel pipe welding fusion rate is high

(5) Compact structure, high heat efficiency

(6) Shock-proof and noise reduced

(7) Convenient for installation, operation and maintenance
