Painted Steel Heat Recovery Steam Generator , Waste Heat Recovery Boiler
What is HRSG?
- The support and hanger of the flue are composed of supports and hangers. The waste heat boiler is divided into six cycle circuits, each of which is composed of a falling pipe and a rising pipe.
- Each section of the flue water supply is introduced from the boiler tube to the lower header of each flue and enters the heating surface.
- HRSG consists of boiler tube, movable smoke cover, furnace mouth flue, inclined 1 section flue, oblique 2 section flue, last 1 section flue, last 2 section flue, feeding pipe (feed slip) slot, oxygen gun mouth, nitrogen seal device and nitrogen seal plug, manhole, micro differential pressure extraction device.
- After the water passes through the heating surface, steam is generated into the inlet header, and then the boiler is introduced into the boiler by the riser. Each flue is connected by flange.
What is the working process of HRSG?
- Fuel, gas and coal are burned to produce high-temperature flue gas to release heat.
- High-temperature flue gas enters the furnace first, then enters the waste heat recovery device of the front smoke box, then enters the pyrotechnic tube, and finally enters the waste heat recovery device of the back smoke box flue channel.
- High-temperature flue gas becomes low-temperature flue gas and is discharged into the atmosphere through the chimney.
- As the waste heat boiler greatly improves the utilization rate of heat released by fuel combustion, it is very energy-saving.
