Abstract: The present disclosure provides a method for freeze-drying cells in a hydrogel comprising nanofibrillar cellulose, the method comprising providing a hydrogel comprising nanofibrillar cellulose, providing cells, combining the cells and the hydrogel comprising nanofibrillar cellulose to form a cell system, and freeze drying the cell system to obtain dried cells in a hydrogel comprising nanofibrillar cellulose. The present disclosure also provides a freeze-dried hydrogel comprising nanofibrillar cellulose and cells.

Abstract: A scrubber for exhaust gas cleaning onboard a marine vessel, comprising a scrubber shell (12) forming a scrubber chamber; and a tubular pipe (18) running through the scrubber shell for feeding scrubber liquid into the scrubber chamber; a concave bowl (32) for connecting the tubular pipe to the scrubber shell, the concave bowl having the shape of a solid of revolution, and the shape curving smoothly from the rim (46) of the concave bowl to the bottom (48) of the concave bowl. The tubular pipe runs through the bottom of the concave bowl in such a way that the bottom encircles the tubular pipe, and the tubular pipe and the bottom are connected to each other. The concave bowl is placed in an opening (34) in the scrubber shell in such a way that the scrubber shell encircles the rim of the concave bowl, and the scrubber shell and the rim are connected to each other.

Abstract: Spooling machine including two side frames spaced at a horizontal distance by a telescopic spacer beam, each frame having a pintle on supports for bearing a drum for cable pipe or hose, the telescopic spacer beam including at least one outer tube and at least one inner tube, which are slidably and telescopically one inside the other, and a locking device positioned between the outer tube and the inner tube for locking the outer and inner tube in adjustable position. The locking device includes a split part of the inner tube extending over a part of the length of the inner tube and dividing the inner tube into sections, and a force element for creating a swelling force on the split part of the inner tube to press the sections against the inner surface of the outer tube.

Abstract: A method for reducing corrosion of a superheater of a steam boiler. The superheater includes a superheater piping. The superheating piping includes a steam pipe where the steam to be superheated is directed. The steam pipe is separated by a protective shell having a surface settling in the flue gas space has a temperature that rises above an upper critical temperature, above which temperature in the flue gas space the compounds from the fuel are substantially in a gaseous form. A superheater of a steam boiler and a circulating fluidized bed boiler.

Abstract: A boiler and a method in a boiler producing thermal energy, the method including: combustion or fuel and combustion air in the furnace of the boiler, delimited by walls; receiving of thermal energy by a steam superheater placed on the wall of the furnace and including at least one heat exchange surface, and supplying of gas or a gas mixture to the front of said heat exchange surface to form a barrier layer for protecting the heat exchange surface from flue gases developed in connection with the combustion. At least one supply device is provided in the superheater or in the direct vicinity of the superheater, to supply gas or a gas mixture to the front of said heat exchange surface to form a barrier layer to protect the heat exchange surface from the flue gases in the boiler.
