Boiler steam distribution header

Product Details

Steam header function

 

Steam header is a key component for steam distribution system, and widely used in power generation, petrochemical, cement, iron & steel, textile, rubber industry. It delivers high pressure steam from boiler to places where steam is needed through parallel branch pipes. As a pressure vessel, its pressure bearing capability and volume should match with boiler.

 

Normally, a complete distribution system should consist steam header, safety valve, pressure gauge, thermometer, flange, steam trap, blowdown valve, release valve, etc.

 

Also, steam header could be used to receive and collect exhaust steam at low pressure, and send it back to condenser for recycle use of water.

Attentions in operation

 

  1. Be sure steam header wall temperature is higher than 20℃ before increasing pressure. Temperature rise/drop rate during startup/shutoff should not exceed 20℃/h.
  2. A slow pressure increase/release is required to avoid stress damage.
  3. There should not be other valves between steam header and safety valve.
  4. A release valve is required when input steam is higher than output steam.
