Abstract

100,072. Bischof, B. Feb. 8, 1915, [Convention date]. Working-fluid supply. -Relates to combustionproduct turbines wherein the charge is diluted by exhaust gases and is heated in a regenerator 5 by the exhaust gases on its way to the combustion chamber 1, the exhaust gases flowing through the regenerator in an opposite direction and parallel to the new charge, and consists in facilitating the transfer of heat in the regenerator by securing high-pressure conditions, i.e. by arranging that the gases from the combustion chamber do not expand in the nozzles 2 down to atmospheric pressure. After acting on the turbine wheel 3, the gases pass through the regenerator 5, and a portion equal in weight to the charge is led by a pipe 20 to the low-pressure chamber 22 for further action on the wheel 3. The rest of the exhaust gases may be led through a cooler 7 and returned to the regenerator 5 by a compressor delivering into a pipe 16, or conducted further to a regenerator 9, a cooler 11, and forced by a compressor 30 back through the regenerator 9 and so to the regenerator 5 by a pipe 35, where it mixes with compressed air supplied by a compressor 29, the mixture being heated in the regenerator 5 by the exhaust gases and then led to the combustion chamber 1, where it mixes with fuel blown in through a nozzle 28 for flameless surface combustion. The pipe 20 tapping the exhaust gases may be located at any point of the regenerator 5 or in front of the same. When gas is used instead of liquid fuel, it is compressed and regenerated separately before mixing in the combustion chamber. Specifications 2565/95 and 21,320/04 are referred to.
