DEVICE FOR INVESTIGATION OF UNDERWATER COMBUSTION OF SOLID MONOFUELS AT OVERLOADS

摘要

FIELD: power industry.;SUBSTANCE: device includes horizontal oriented disc-shaped combustion chamber installed on platform with possibility of rotation and in which on its diametrically opposite sides there installed are two additional combustion chambers made in the form of composite shells the bottom part of which faces the rotation axis, and tested fuel samples with glowing filament are fixed in them. In one of additional chambers there provided is thickened bottom providing the location of centre of gravity of non-equipped shell on its inner surface of bottom, and on outer side surface of shell there provided are projections with cylindrical cavities. Pins of clamp fixed in disc-shaped combustion chamber are inserted in the above cavities with possibility of turning the additional combustion chamber relative to transverse axis through 180°; at that, counter-weight is fixed on outer side of bottom part of composite shell. Glowing filaments of both additional chambers are electrically connected to lower electric contact installed on insulating stool in central part of bottom of disc-shaped combustion chamber. On upper edge of electric contact there is a cavity into which mating upper electric contact installed on central fixed head piece is inserted.;EFFECT: invention allows providing underwater combustion of solid monofuels at overloads, determining combustion speed in these conditions and investigating the shape and structure of combustion surface after interruption of gas formation during the test.;2 cl, 7 dwg
