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 11):
A recovery boiler including:\n a furnace configured to combust waste liquor and including an inlet to receive the waste liquor and an outlet for chemical smelt produced by the combustion, wherein the furnace includes walls extending vertically to confine and direct upwards flue gases generated by combustion; superheaters arranged in an upper region of the furnace; a flue gas duct adjacent and horizontally offset from the furnace, wherein the flue gas duct includes a first channel attached to the furnace and having a flue gas inlet in an upper region of the first channel and a flue gas outlet at a bottom region of the first channel, wherein the inlet receives flue gases flowing downstream from the superheaters; wherein the first channel includes a reheater and a heat recovery unit and the heat recovery unit is at least one of an economizer and a boiler bank, and wherein the reheater and heat recovery unit in the first channel are arranged to simultaneously receive flue gas flowing down through the first channel.
