2 Parts and How it Works plant: Boiler


PLTU Paiton, Jawa Timur

Steam Power (power plant) consists of several major systems, ie:

1. Turbine & Generator

2. Boiler (Steam Generator)

3. Coal Handling System

4. Ash Handling System

5. Flue Gas System

6. Balance of Plant

Turbine & generator can be regarded as the heart of the plant, because of the electrical energy is generated. Generator which rotates with constant speed, generating electrical energy supplied to the network interconnection and then distributed to consumers.

Steam turbine (steam turbine) which serves to turn a generator, consisting of HP (high-pressure) turbine, IP (intermediate-pressure) turbine and LP (low-pressure) turbine.
Turbine & generator has some supporting equipment, the lubricating oil system and the generator cooling system.

Boiler (steam generator) function to convert water into steam. Very high-pressure steam produced by boilers used to rotate the turbine. Boiler is divided into several sub-systems, namely:

- Boiler steel structure house
- Pressure parts
- Coal system
- Water system
- Boiler Cleaning System
 
Boiler (Steam Generator)
As the name implies, the boiler house structure is steel building steel frame structure, in which all equipment installed steam generator. This steel frame building height between 50 m (plant capacity of 65 MW) to 100 m (600 MW capacity power plant).
Pressure part system is a major part of the steam generator. These sections serve to convert water into high pressure steam (superheated steam) at temperatures between 500-600 degrees C.
Water supplied to the boiler, first came into the economizer inlet header, continue to be distributed to the economizer elements, reconvening in eco outlet header and then piped into the steam drum. Backpass economizer is located in the area (at the back of the boiler house), while the steam drum at the front of the roof area.
Named economizer as part of this serves to raise the temperature of incoming water boiler by utilizing exhaust gases from the combustion of coal in the furnace area (combustion chamber). By preheating the boiler economizer this efficiency can be improved.
Due to heating by convection in the furnace and due to gravity, water in the steam drum water circulation had dropped to the lower water wall headers via pipe downcomers. From the lower waterwall headers again experienced water circulation by heat, water rises toward the upper wall-tube headers via the tube water wall panels. Then from the upper waterwall header restored water to the steam drum through riser pipes.
So the result of coal burning hot water undergoes a continuous circulation. This circulation causes the water in a water wall panels & steam drum partially transformed into steam.
In a large-capacity power plant, boiler circulation is assisted by water circulating pump mounted on the bottom of the pipe downcomers. Faster circulation will cause the speed of the water changes into steam are also greater.
Inside there is a steam separator drum which serves to separate the steam from the water. The steam is separated, from the steam drum steam is channeled to the roof inlet header connected to the boiler roof panel. Boiler roof panel that carries the steam back into backpass panel.
of backpass panels, steam is channeled into the Low Temperature superheater (LTS) that is in backpass area, above the economizer elements. of LTS steam superheaters channeled into Intermediate Temperature (ITS). Next through the superheater pipe-desuperheater, steam superheater was taken to High Temperature (HTS) elements to undergo the final heating process becomes superheated steam.
ITS and HTS elements located inside the furnace (coal combustion chamber) the top. Some boiler manufacturers give different names to the LT, IT and HT superheater.
Of High Temperature superheater outlet headers, superheated steam with temperatures of 500-600 degrees C and very high pressure to the steam turbine channeled through the main steam pipe.
In the small-capacity power plant, the steam goes to the High Pressure Turbine, continues to Low Pressure Turbine and out into the condenser. While the large-capacity power plant, after turning the HP turbine steam is brought back to the boiler through the cold reheat piping.
Inside the boiler the steam to warm up again in Reheater elements. Reheater elements are usually located between the furnace area and backpass area.
After having re-heating, steam reheated to Intermediate Pressure Turbine channeled through pipes Hot reheat. After turning Intermediate and Low Pressure Turbine, a new steam out into the condenser.
