Abstract: A the method and apparatus for cleaning of flue gas from a boiler, and the recovery of heat from gas, the flue with the flue gas being led from the boiler through a heat exchanger in such a manner that it still has a temperature above the acid dew point. The flue gas is then led to a scrubber tower and is washed with a scrubber fluid from a sedimentation tank. The pH value of the scrubber fluid is measured with a measuring element and a liquid additive base is introduced from a tank. The sediment in the sedimentation tank is fed into a high-speed reactor, from which a basic fluid is led to one or more collection vessels supplied with clean gas from a chimney via a blower resulting in the formation of CaCO.sub.3 which, not being easily dissolved, is precipitated. The cleaned base is fed to the tank. The high-speed reactor is supplied with lime water through a ring main and a dosing pump from a lime water plant.

Abstract: A stoking plant for fuel in whole bales, where the bales are conveyed on a transport tract (8) from a store and stoked in the whole condition into one of a number of combustion furnaces (2) with boilers (1), comprises a slide-gate (10) through which a bale transport carriage (5) can be filled with a bale of fuel. The transport carriage (5) then conveys the bale forward to the furnace (2) which is in need of fuel. When the bale transport carriage is positioned opposite the stoking door (4) of the furnace, a cover door (6) is released which is pressed against the carriage (5) by springs (13), a switch element is activated and the stoking door (4) is opened, and the bale is pushed into the furnace (2) by a piston (7). The piston (7) is withdrawn, but in such a manner that the furnace door (4) is closed before the cover door (6) is withdrawn to the start position. The bale transport carriage (5) is a tubular carriage which travels on running rails (9).
