Product Introduction

• Heat Recovery Steam Generator, refers to the use of various industrial process waste gas, waste or waste liquid waste heat and the heat was generated by the combustion of combustible substances to heat water to a certain temperature boiler.
• 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.HRSG is very energy-saving.
• Oil-fired boilers, gas-fired boilers and coal-fired boilers with smoke boxes and flue gas waste heat recovery are also called Heat Recovery Steam Generator. Heat Recovery Steam Generator can produce hot water or steam through waste heat recovery to supply other sections.
