Horizontal Drum Water Tube Coal Fuel Steam Boilers Long Life&High Safety
1. The mixture of steam and water coming from the water wall enters the drum through the upper inlet pipe of the drum. Along the narrow annular passage formed by the inner wall of the drum and the arc liner, the steam-water mixture can be uniformly transferred to the inner wall of the drum at an appropriate flow rate, thus overcoming the difficulty of excessive temperature difference between the upper and lower walls of the drum during start-up and shutdown of the boiler and enabling faster start-up.
2. The steam-water mixture entering the drum enters the steam-water cyclone separator, and uses the inertia of changing the flow direction to separate the steam-water mixture, which is the first separation of the steam-water mixture.
3. The separated steam still contains a lot of water. It enters the corrugated plate separator from the top of the separator. The steam with some water droplets flows through the cracks between the corrugated plates, and the water film is formed on the metal wall to flow downward.
4. The steam after secondary separation is finally cleaned by steam, and gravity separation is carried out by using the density difference of water, which is the third separation.
5. After three separations, the steam meets the steam quality standard, and leads to the platen superheater from the saturated steam pipe at the top of the drum.
1. Usually there is coexistance of steam and water in the steam drum. Under certain pressure, the temperature of water vapor in the drum is also different(refers to the characteristics table of water dissolving, i.e. the rated saturation temperature under rated pressure). If it is in the saturated state, the temperature of water is the same as that of steam.
2. The circulation of water in drum is a convective heat cycle(except for the heat radiation from the outer wall of drum and the direct heat transfer from the smoke pipe or the outer wall). The heat is exchanged in the process of moving upward because of the light weight of hot water. After a certain amount of heat is reaches, part of the water is converted to gaseous state.
There are main functions of steam drums as below:
1. It is the junction hub of three processes of working medium heating, evaporation and superheating to ensure the normal water circulation of boilers.
2. Inside, there are steam-water separator and continuous blowdown device to ensure the quality of boiler steam.
3. Have a certain amount of water, have a certain capacity of heat storage, ease the change speed of vapor pressure.
4. The drum is equipped with pressure gauge, water level gauge, accident discharge water, safety valve and other equipment to ensure the safe operation of the boiler.
