Abstract

17,362. Hoegerstaedt, E. C., and Townsend, E. C. Aug. 28. Steam generation by direct contact of combustion products. - The principle of the invention is illustrated diagrammatically in Fig. 1 (Sheet 1). Water is passed from two upper tanks A, B into a lower tank C, and is replaced by a combustible mixture in a compressed or non-compressed state. Air is then pumped into the tank C, thereby forcing a certain quantity of water back into the tanks A, B and compressing the charges in them. The mixture in the tank A is then fired. The resulting gases force open the valve N and enter the tank C, causing an additional quantity of water to enter the tank B and compress the charge to a higher degree. The mixture in the tank B is then fired, the heat of combustion converting the water, or part of it, into steam. A pump X is provided for filling the tanks A, B after the charges have been fired. Valves control the connexions between the three tanks and the pumps. Fig. 1 (Sheet 2) shows how the principle can be applied to a generator to produce a constant supply of mixed steam and combustion products. The tanks A, B, C are fitted in duplicate, the cycle of operations being shifted three stages back or forward in respect to A', B<1>, C<1>. A constant supply of power fluid is taken from either B or B<1>. A portion only of the gases resulting from the combustion in B is utilized to force sufficient water out of C into A.
