Naturally Circulated High Pressure Heat Recovery Generator For Industry


♢What is HRSG?


  • HRSG, as the name implies, refers to a boiler that uses various waste gases, waste materials, waste heat in waste gas or waste heat and the heat generated by combustion of combustible materials to heat water to a certain temperature. An oil-fired boiler, a gas-fired boiler, and a coal-fired boiler having a smoke box and a flue heat recovery are also referred to as a waste heat boiler, and the waste heat boiler can produce hot water or steam through waste heat recovery to be supplied to other sections.

♢What is the working principle 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.

♢What are the advantages of HRSG?
