摘要： An arrangement for and a method of horizontally supporting a side wall of a top-supported flue gas pass. The side wall includes evaporative water tubes at a first temperature, and the flue gas pass includes a superheating tube at a temperature higher than the first temperature and having rigid, horizontal tube legs extending across the flue gas pass between the side wall and a second side wall of the flue gas pass and being supported from above by a hanger, which is in operation at a temperature higher than the first temperature. Rigidity of the side wall is increased by horizontally supporting the side wall by the horizontal tube legs including end sections attached to the side walls by attaching means allowing relative movements of the end sections with respect to the side wall to which the end section is attached, only in a direction of their relative thermal movement.

摘要： An arrangement for controlling a flow of solid particles includes a vertical inlet pipe for directing solid particles downwards and having a bottom at a level L0, a first outlet chute and a second outlet chute in particle flow connection with the vertical inlet pipe and a fluidizing device for directing controlled first and second sub flows to the first and second outlet chutes. The arrangement includes a branch in particle flow connection with an opening on a side wall of the vertical inlet pipe for directing the first sub flow of solid particles to the first outlet chute and a horizontally extending intermediate pipe for directing the second sub flow of solid particles to the second outlet chute. The intermediate pipe includes at least one nozzle feeding fluidizing gas to the intermediate pipe and has a first end in particle flow connection with the bottom of the inlet pipe.

摘要： A method of reducing sulfur dioxide emissions of a circulating fluidized bed boiler plant. A first stream of sulfur-containing carbonaceous fuel is fed at a first feeding rate to a furnace of the boiler. A second stream of calcium carbonate containing absorbent having a predetermined d50 particle size is fed at a second feeding rate to the furnace. Oxygen containing gas is fed to the furnace for fluidizing a bed of particles forming in the furnace. Fuel is combusted with the oxygen and the sulfur in the fuel is oxidized to sulfur dioxide. The calcium carbonate is calcined to calcium oxide in the furnace. A portion of the calcium oxide is used to sulfate a first portion of the sulfur dioxide to calcium sulfate in the furnace.

摘要： A spring hammer for rapping a surface, the spring hammer includes an anvil with an impact surface. The anvil can fastened to the surface to be rapped. A movable piston has a first end that is in operation moved towards the impact surface of the anvil. A guiding structure guides the piston to move in a defined direction with respect the anvil and a device for launching the piston to move the piston towards the impact surface of the anvil. The piston is a solid block in which the first end of the piston is machined to an integrated flexible spring geometry.

摘要： A boiler system includes a support construction and a furnace supported to the support construction at a vertically middle section of the furnace, the furnace being enclosed by water tube walls having two side walls and two end walls, a roof and a bottom, the side walls having a total height (H) from the bottom to the roof. Each of the two side walls has a vertical upper portion that extends from the roof to a level of thirty to seventy percent of the height (H), a lower portion that extends from the bottom to a level of thirty to seventy percent of the height (H) and has a vertical upper portion, and an in downward direction outwards bent intermediate portion at a level between the upper portion of the side wall and the vertical upper portion of the lower portion of the side wall. The support construction includes horizontal wall supporting beams that are arranged parallel to the side walls at a level below the roof of the furnace and directly above the vertical upper portions of the lower portions of the two side walls, and the furnace is supported to the support construction by having the intermediate portions of the side walls connected to adjacent horizontal wall supporting beams so as to balance vertical loads of the furnace.

摘要： A bottom-supported boiler includes a boiler pressure body having a rectangular horizontal cross section formed by joining four planar water tube walls pairwise together so as to form four corner sections, and a support construction. The support construction includes four vertical columns vertically supported to the ground, the vertical columns being arranged outside of the boiler pressure body so that adjacent to each of the corner sections is arranged one of the four vertical columns. Each of the vertical columns is attached to the respective corner section so that vertical loads of the boiler pressure body are balanced by the four vertical columns.

摘要： A tubular waterwall structure in a fluidized bed reaction chamber includes horizontally adjacent first and second portions forming a corner structure and constituted by vertical tubes and fins centrally attached to the tubes and having a first width. The first wall portion has an outermost tube next to the corner, an upper portion defining an upper vertical plane in an upper level range and a lower portion defining a lower (outwards) vertical plane in a lower level range. The lower portion has a refractory lining. The second wall portion is vertical and has an outermost tube next to the corner. The outermost tube of the second wall portion is in the lower level region connected to the outermost tube of the first wall portion by a planar lower beveled corner fin having a refractory lining and a width that is larger than the first width.
