Hi Pressure Horizontal Painted Industrial Boilers And Heat Recovery Steam Generators

Introduction of HRSG

HRSG is composed of boiler barrel, mobile smoke hood, furnace mouth section flue, inclined 1 section flue, inclined 2 sections flue, end 1 section flue, end 2 sections flue, feeding tube (feeding chute), oxygen nozzle, nitrogen sealing device and nitrogen sealing plug, manhole, differential pressure device, support and hanger of flue.
HRSG boiler is divided into six circulation loops, each circulation loop is composed of the down pipe and up pipe, each section of the flue feed water from the boiler tube through the down pipe into the lower collection box of each flue into each heating surface, water through the heating surface to produce steam into the inlet collection box, then by the rising pipe into the pot.All flanges are connected with flanges.

Features of HRSG

Kiln (AQC) HRSG Features	Kiln (SP) HRSG Features
1.Modular assembly structure, reliable sealing expansion	1. Heating surface tubes and headers with privildged connection structure, reducing mechanical shock and vibration
2. Adopt wear fin tubes, boiler pressure parts life assurance	2. By mechanical vibration cleaning mode, continous cleaning mode little impact on system operation
3.Unique flash technology, the boiler outlet temperature is reduced to below 90ºC	3.Set sealed scraper gray machine, greatly reducing dust tail.

Working Process of HRSG

The combustion of fuel oil, gas and coal produces high-temperature flue gas to release heat. The high-temperature flue gas enters the furnace chamber first, then enters the waste heat recovery device in the front smoke box, then enters the pyrotechnical pipe, and finally enters the waste heat recovery device in the flue pipe of the rear smoke box.
The high-temperature flue gas turns into low-temperature flue gas and is discharged into the atmosphere through the chimney.Because the waste heat boiler greatly improves the utilization rate of the heat released by fuel combustion, this kind of boiler is very energy-saving.
