Alloy Painted HRSG Heat Recovery Steam Generator , Heat Recovery Steam Boiler

Alloy Painted HRSG Heat Recovery Steam Generator , Heat Recovery Steam Boiler

Product Introduction▷

• HRSG heat recovery steam generator consists of drum, movable hood, furnace mouth flue, inclined 1 section flue, inclined 2 section flue, end 1 section flue, end 2 section flue, feeding tube (feeding slip) trough, oxygen Muzzle, nitrogen seal device and nitrogen plug, manhole, differential pressure and pressure device, flue support and hanger.
• HRSG is divided into six circulation loops. Each circulation loop is composed of a down pipe and a riser pipe. Each section of the flue feed water is introduced from the drum through the down pipe into the lower header of each flue and enters each heating surface. After the heated surface, steam is generated into the inlet header, and then introduced into the drum by the riser. Each flue is flanged.

Features▷

• The high-temperature flue gas released from coal-fired combustion is sent to the inlet of the waste heat boiler through the flue, and then flows through the heat exchanger, the evaporator and the economizer, and finally discharged into the atmosphere through the chimney.
• The exhaust gas temperature is generally 150-180 ° C, and the flue gas The heat released by the temperature from the high temperature to the exhaust temperature is used to turn the water into steam.
• The boiler feed water first enters the economizer, and the water absorbs heat in the economizer to rise to a saturation temperature slightly lower than the steam drum pressure to enter the drum. After the water entering the drum is mixed with the saturated water in the drum, the falling pipe below the drum enters the evaporator to absorb heat and start to produce steam.
• Usually only a part of the water turns into steam, so the steam and water mixture flows in the evaporator. . The steam-water mixture leaves the evaporator and enters the upper drum.
• The water is separated by the steam-water separation equipment.
• The water falls into the water tank of the drum and enters the down pipe to continue to absorb the heat. The steam enters the superheater from the upper part of the drum and absorbs heat to make the saturated steam become superheated steam.
• According to the three stages of the steam production process, three heating surfaces, namely the economizer, the evaporator and the superheater, if only superheated steam is not required, only saturated steam is required, and the superheater may not be installed. When there is reheat steam, a reheater can be added.

Working Principle▷

• Fuel, gas, and coal are burned to produce high-temperature flue gas to release heat.
• The 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 in the rear smoke box flue.
• The flue gas becomes low-temperature flue gas and is discharged into the atmosphere through the chimney.
• This type of boiler is very energy efficient because the waste heat boiler greatly increases the utilization of heat released by fuel combustion.
