    摘要: 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.

    摘要: Heat energy is generated from low-grade alkaline fuels (such as manure and lignite) in a gasifier-combustor system. The fuel is gasified at a temperature of less than 900.degree. C. in a circulating fluidized bed gasifier comprising a first cyclone separator. The gas leaving the first separator is conveyed to a second cyclone separator. The gas leaving the second separator is burned in a boiler at a temperature of at least 900.degree. C. Alkaline containing material is removed and collected from the gasifier, the first and second separators, the boiler and a filter before the gas is vented to the atmosphere.
