Heat Exchange 100% Solid Solution Superheater And Reheater For Power Plant Boiler

Description

Superheater
Fossil fuel power plants often have a superheater section in the steam generating furnace.The steam passes through drying equipment inside the steam drum on to the superheater, a set of tubes in the furnace. Here the steam picks up more energy from hot flue gases outside the tubing, and its temperature is now superheated above the saturation temperature.

Reheater
Power plant furnaces may have a reheater section containing tubes heated by hot flue gases outside the tubes. Exhaust steam from the high-pressure turbine is passed through these heated tubes to collect more energy before driving the intermediate and then low-pressure turbines.

Function

Superheater is to increase the temperature of the steam above its saturation point.
Reheater is basically a superheater that superheats steam exiting the high-pressure stage of a turbine. The reheated steam is then sent to the low-pressure stage of the turbine. By reheating steam between high-pressure and low-pressure turbine it is possible to increase the electrical efficiency of the power plant cycle beyond 40%.The reheat cycle is used in large power boilers since it is feasible economically only in larger power plants.

Advantages & Disadvantages

Pendant-type 1.Firm structural support

1. Flow blockage by condensed steam

2. Needs slow restart to purge the water that accumulates in the bottom. supported from above

Inverted-type 1.Proper drainage of the condensed steam

1. Lack the structural rigidity, especially in high speed gas flow Supported from below

Horizontal -type

1. Proper drainage

2. Good structural rigidity.

They do not view the flam directly so they are mainly from the convective type Usually supported in the vertical gas ducts parallel to the main furnace.

Advance technology

1	HDB has extensive experience using their remaining useful life analysis system to predict the lifespan of tubes.
2	The system measures the oxide and wall thickness of the tube during an on-site non-destructive test and this is used to calculate the remaining useful life.
3	HDB developed the oxide measuring technology in 1991 and it is now used as the standard throughout the world.

Details

1	Material composition	Carbon steel, alloy steel or heat-resistant steel, collection boxes and other supporting material. Tubes are customized types of specifications.
2	Design pattern	Vertical or horizontal layout.
3	Advantages	Beautiful appearance, size, accuracy, first-class bending and welding technology, first-class detection equipment.

Product Function

1.The function of the superheater in the thermal power plant is to remove the last traces of moisture ( 1 to 2%) from the saturated steam coming out of boiler and to increase its temperature sufficiently above saturation temperature.

2.The super-heating heating raises overall overall cycle efficiency efficiency as well as avoids too much condensation in the last stages of the turbine which avoids the blade erosion.

3.The heat of combustion gases from furnace is utilized for the removal of moisture from steam and to superheat the steam.

4.Super-heaters usually have several tube circuits in parallel with one or more return bends, connected between headers.
