| 20120073483 | METHOD FOR SUPPLYING COMBUSTION AIR TO A FLUE GAS AIR PREHEATER, A PREHEATING APPARATUS, AND AN AIR GUIDE SLEEVE - A flue gas air preheating apparatus for combustion air in a boiler of a power plant. An air pipe is placed in a flue gas duct. An air guide sleeve is provided at an initial end of the air pipe at least partly inside the air pipe. The air guide sleeve is made of a poorly heat conductive material and is designed to diminish turbulence in air flow and has an inflow end and a second end placed inside the air pipe. The shaping of the second end is designed to diminish turbulence in the air flow. The air guide sleeve includes splits or notches that become wider towards the second end. A method and a corrosion shield. | 03-29-2012 |
| 20120060774 | PREHEATER FOR COMBUSTION AIR, AND A POWER PLANT - A preheating device for combustion air in a boiler. First heat exchanger structures fitted in a flue gas duct heat primary air. A first air supply area in the wall of the flue gas duct supplies air to be heated to the first heat exchanger structures. Second heat exchanger structures fitted in a flue gas duct heat secondary air. A second air supply area in the wall of the flue gas duct supplies air to be heated to the second heat exchanger structures. The first air supply area is opposite the second air supply area. Also a power plant. | 03-15-2012 |

| 20110140317 | SHIELDING ARRANGEMENT FOR THE SMELT SPOUT AREA OF A RECOVERY BOILER - A smelt spout area of a recovery boiler. A bank of smelt spouts is connected to a lower part of the boiler for directing smelt from the boiler to a dissolving tank. A working area is in front of the bank of smelt spouts. A shielding wall is located in front of the bank of smelt spouts and arranged movable in relation to the bank of smelt spouts to separate the bank of smelt spouts from the working area and persons working on the working area. | 06-16-2011 |
| 20110109023 | CLEANER EQUIPMENT FOR THE SMELT SPOUTS OF A RECOVERY BOILER - A cleaning unit for smelt spouts of a recovery boiler. A motorized cleaning member is configured to clean smelt spouts of a recovery boiler. A motorized transfer device is configured to transfer the cleaning unit from the location of a first smelt spout to the location of a second smelt spout. | 05-12-2011 |
| 20100319782 | Method For Monitoring The Composition Of Flue Gas Resulting From A Thermal Process - The composition of flue gas generated in a thermal process, especially in the combustion of bio fuel or refuse-derived fuel, is monitored by measuring the quantity of particles belonging to certain size categories in at least one point along the flow path of the flue gas. Such particle size categories are chosen as objects of the measurement, in which the particles are known to consist mainly of alkali chlorides. | 12-23-2010 |
