Fire tube boiler for steam generation Thailand Bangkok
In order to generate superheated steam, GETABEC three-pass boilers can be equipped with several different superheater systems.
For Lower temperature superheated steam ( superheating by 40 to 60 K ), the superheater is installed within the front reversing chamber. These superheaters also called “steam dryers”, are operated without temperature control. When starting up the boiler, this arrangement does not need any particular measures, such as cooling the superheater or any flue gas side bypasses, as the flue gas temperature in the front reversing chamber is significantly below the scaling temperature of the material used for the superheater tubes.
For Higher steam temperatures , the superheater is installed within the rear reversing chamber. As a result, higher steam temperatures are possible. These superheaters are delivered with various types of temperature control systems. Due to the high temperature in that area, specific safety measures, such as operating on the lowest burner load or cooling during start-up, must be taken before the boiler can be connected to the grid to protect the superheated tubes.
