Advantages and Disadvantages of High Pressure Boiler

Advantages and Disadvantages of High Pressure Boiler Points : Advantages and Disadvantages of High Pressure Boiler Advantages
  1. Every part are equally heated, then the danger of overheating is reduced and thermal stress problem is simplified.
  2. Heat of combustion is utilised extra efficiently by use of small diameter tube in large number and in many circuits.
  3. The tendency of scale formation is eliminate due to high velocity of water through the tubes.
  4. Pressurized combustion is use which decrease rate or firing or fuel thus rising the rate of heat release.
  5. Use of high pressure and high temperature steam is inexpensive.
  6. Due to compactness less floor space is necessary.
Disadvantages
  1. Bubbles are formed at inner face of heating tube. Because of which it reduces the heat transfer rate.
  2. Tubes are possible to be overheated in case of water flow is insufficient.
  3. It can only function on liquid or gaseous fuels.
