Issues with using 1.0MPa steam to start up the reformation drum?
Thread Content
Before starting up the reformation process and activating the four-in-one furnace, it is necessary to supply steam at a superheat pressure of 1.0 MPa. What is the state of the steam drum at this time? Is it already filled to a certain water level (meaning that both the water protection section and the evaporation section are filled with water)? Or is there no water in the drum? If there is no water in the drum, and 1.0 MPa of steam is introduced, won’t that result in the entire drum being filled with steam as well (with both the water protection section and the evaporation section being filled with steam)?
What do you think? Of course, the drum should be filled with water. During the heating process of a four-in-one furnace, the pressure is generally at 1.0 Mpa; the saturation temperature is used at that point, and steam is utilized in advance to provide protection for the superheating section! Used to protect the overheating steam boiler tubes!
Before ignition at the four corners, the steam drum is always filled with water up to a certain level. As the furnace temperature rises, it is possible to activate the superheater protection steam in advance in order to protect the tubes in the superheater section. The amount of steam supplied can be controlled based on the temperature in the furnace’s convection section; all that is necessary is to ensure that the tubes do not burn out due to lack of steam
