Abstract:
An arrangement in a recovery boiler having a furnace for combusting waste liquor and a flue gas duct including vertical flue gas channels, at least some of which are provided with heat recovery units for recovering heat from flue gases. The first flue gas channel downstream of the furnace is provided with a reheater and one of the following heat recovery units: an economizer or a boiler bank. The reheater and the second heat recovery unit are located one after the other in the horizontal incoming direction of the flue gas, so that in a flue gas channel the flue gas flows in a vertical direction from above downwards and heats the reheater and the second heat recovery unit simultaneously. The heat recovery elements of the reheater and the second heat recovery unit may be positioned side by side in a direction that is crosswise with respect to the horizontal incoming direction of the flue gas.

Claim (Index 1):
An arrangement in a recovery boiler having a furnace for combusting waste liquor for producing chemical smelt and flue gases and a flue gas duct comprising vertical flue gas channels, at least some of which are provided with heat recovery units for recovering heat from flue gases, said heat recovery units having a width of substantially that of the flue gas duct,\n wherein a first flue gas channel of the vertical flue gas channels is downstream of the furnace and is provided with a reheater and a heat recovery unit, wherein the heat recovery unit is an economizer or a boiler bank, and wherein the reheater and the second heat recovery unit are arranged, with respect to a horizontal incoming direction of the flue gas one after the other so that in the first flue gas channel the flue gases flow in a vertical downwards direction through the reheater and the second heat recovery unit simultaneously and thereby heats the reheater and the second heat recovery unit simultaneously.
