Horizontal Customized Hot Water Boiler Steam Drum with High Efficiency

✎What is boiler steam drum?

Boiler steam drum refers to the pressure drop or rise caused by the water circulation. It can also be understood that drum is the pressure change formed by the fusion of gas and water. The air and water molecules in the limit pressure will increase the pressure rise of gas, resulting in the pressure gathering molecules produced after the high pressure reaches a certain value. In industry, drum tank is an industrial equipment which can withstand the air pressure and water level pressure produced by drum.
Drum, also known as drum, is the most important pressurized component in natural circulation boilers. It is mainly used in medium pressure and high pressure subcritical boilers in power production.

✎What are the accessories of boiler steam drum?

(a) The main components in a boiler system are the boiler feedwater heaters, deaerator, boiler, feed pump, economizer, boiler, superheater, attemperator, steam system, condenser and the condensate pump.

(b) In addition there are sets of controls to monitor water and steam flow, fuel flow, airflow and chemical treatment additions.

✎What are the main functions of boiler steam drum?

The main functions of drums are:

✎What should be noted about boiler steam drum?

• Boiler steam drum water level is one of the most important power plant parameters to both measure and control. Control of the proper water level in the boiler is critical for safe operation of the boiler. If the level is too low, boiler tubes will be damaged by overheating. If the level is too high, steam separators will not function properly, temperature control will be difficult, and the superheater tubes and turbine could be damaged by moisture or water treatment chemical carryover.

✎What is the working progress of boiler steam drum?

1. The separated steam is drawn out from the top section of the drum and distributed for process.
2. Further heating of the saturated steam will make superheated steam normally used to drive a steam turbine.
3. Saturated steam is drawn off the top of the drum and re-enters the furnace in through a superheater.
4. The steam and water mixture enters the steam drum through riser tubes, drum internals consisting of demister separate the water droplets from the steam producing dry steam.
5. The saturated water at the bottom of the steam drum flows down through the downcomer pipe.

✎What is the water circulation of boiler steam drum?

Natural Circulation

In this circulation, the water flowing from upper drums through downcomers which is located in the boiler is relatively cold, flow down to mud drum. From mud drum, water flow back into the steam drum after passing through the evaporator tubes.

Forced circulation

In this forced circulation, fluid is pumped through the evaporator. This causes the boiler can work with very high pressures.
