Secondary air in circulating fluidized bed boilers
Thread Content
In a circulating fluidized bed, what is the approximate wind speed of the secondary air supplied to the oil gun?
The feed gun generally uses hot air; according to the Rokudou Technical Specifications, the recommended wind speed for hot air is 15~25 m/s
The air supplied to our company’s fuel injection gun is primary air, with a flow rate of approximately 30,000–40,000 m3/h; this figure represents the total amount of air including both mixed air and ignition air.
