The circulating fluidized bed technique allows to burn highly sulphurated products while respecting a low emission rate of issue of sulfur and nitrogen oxides in the fireplace. The fluidisation air of the outlet beds, siphons and ashes coolers is supplied by positive displacement blowers.
In power plants, a continuous flow of low-pressure air is used to remove sulphur dioxide from the exhaust flue gases. To guarantee uninterrupted pollution control and make sure these plants are up and running continuously , the used compressed air solution needs to be highly reliable and energy efficient.
Vacuum blowers are used to suck water and sand mixture, after being used during crude oil extraction by means of pressurised water injection process.
