The main steps of starting the supercritical 600 MW unit up through IP cylinder

as well as warming the cylinder up

switching the cylinder over

and other key technologies have been presented

and the advantages of starting the unit up through IP cylinder being summarized.Although the said start-up mode is somewhat complex

and the starting operation is slightly more difficult

but it is a safe

economical

rapid

and flexible way to start the unit up.It is recommented to adopt some measures for warming the cylinder up

such as the main steam prewarming combined with self-warming with the cylinder being tightly covered

prewarming with auxiliary steam or reheating steam from neighboring furnace

to further accelerate the start-up

reducing consumption in start-up.
