Vertical Customized HRSG Heat Recovery Steam Generator In Power Station

HRSG Introduction

Waste heat boiler, as the name suggests, refers to the use of various industrial process waste gas, waste waste or waste liquid waste heat and the heat generated by the combustion of combustible substances to heat water to a certain temperature boiler.Oil-fired boilers, gas-fired boilers and coal-fired boilers with smoke boxes and flue gas waste heat recovery are also called waste heat boilers. Waste heat boilers can produce hot water or steam through waste heat recovery to supply other sections.

HRSG Features

• Coal combustion of high temperature flue gas released by the flue entrance to waste heat boiler, and then through the superheater, evaporator and economizer, and finally by the chimney discharged into the atmosphere, exhaust smoke temperature is 150 ~ 180 ℃, the flue gas temperature from high temperature to the heat release by the exhaust temperature is used to make water into steam.
• The boiler feed water first enters the economizer in which the water absorbs heat and heats up to a saturation temperature slightly below the drum pressure and enters the drum.After the water entering into the drum is mixed with the saturated water in the drum, it goes into the evaporator along the down pipe below the drum to absorb heat and start producing steam. Usually, only part of the water turns into steam, so the mixture of soda is flowing in the evaporator.
• The steam-water mixture leaves the evaporator and enters the upper pot barrel and is separated by the steam-water separation equipment.
• The water falls into the inner space of the pot barrel and enters the downcomer to continue to absorb heat and produce steam, while the steam enters the superheater from the upper part of the pot barrel and absorbs heat to turn the saturated steam into superheated steam.According to the three stages of steam production process corresponding to three heating surface, namely economizer, evaporator and superheater, if no superheated steam is needed, only saturated steam is needed, superheater can not be installed.When there is reheat steam, a reheater can be added.

HRSG Working Principle

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.
