How long does it take for a 75t circulating fluidized bed boiler to ignite and steam? Our factory takes seven to eight hours. What is the problem? Is there a solution? kowtow

No, this time is not only a matter of combustion, but also a time of simultaneous expansion for metal heating surfaces, steel frames, concrete and so on. If the temperature rises too fast, the metal, especially the metal on the heating surface, will expand rapidly, while the non-metallic structures such as the furnace arch will not expand when heated, which will lead to the furnace arch falling off.
