Abstract
The invention comprises an apparatus for separating solids from flue gases in a circulating fluidized bed reactor having a horizontal cyclone separator, the gas inlet channel of which is connected to the upper part of the reactor, a return channel of the solids to the lower part of the reactor, and a gas outlet to a convection part of the reactor. In order to accomplish a compact construction, there is a plurality of coaxial turbulence chambers in the cyclone separator, the opposite walls of which form gas outlet channels between the turbulence channels.
Claims7
Apparatus for separating solids from flue gases produced in the combustion chamber of a circulating fluidized bed reactor comprising:
- a horizontal cyclone separator comprising a plurality of coaxially aligned turbulence chambers located above the combustion chamber, a gas inlet channel extending from an upper part of the combustion chamber to an upper part of the cyclone separator, a plurality of return channels for returning solids from said cyclone separator to the combustion chamber, and a plurality of gas outlet channels from the separator to a convection part of the reactor, said gas outlet channels located between said coaxially aligned turbulence chambers.
