Disclosed is a steam buffer for use in a steam engine power plant with a closed system and designed to alternately accumulate and emit steam under high pressure and temperature. The steam buffer improves upon conventional steam accumulators which contain water and steam at high pressures and temperature in a large pressurized vessel. The steam buffer functions to store heat in solid material in the walls of a large number of long flow channels with a hydraulic diameter at least as small as 0.5 mm contained in a casing. The flow channels may be formed, for example, by capillary tubes attached to each other or, alternatively, by fine grains of metallic or ceramic material sintered together. The walls of the flow channels perform as the primary heat storing material and are made of a material having a melting point higher than the operating temperature in the steam buffer.
A steam buffer for utilization in a steam engine plant with a closed steam system designed to alternately accumulate and emit steam under high pressure and temperature, comprising a high temperature connection for steam, a low temperature connection for feed water, a plurality of elongated flow channels having a hydraulic diameter no more than 0.5 mm through which flows the steam and the feed water between said high temperature connection and said low temperature connection, said flow channels being surrounded by pressure resistant walls, said walls being made of a material that has a melting point above the highest occurring temperature in the steam buffer and being a primary heat storage substance for the steam buffer.
A steam buffer for use in a steam engine power plant to store and release steam energy, comprising a low temperature connection to feed water, a high temperature connection for steam, a plurality of flow channels formed in pressure resistant walls extending between said low and high temperature connections, and said flow channels having a diameter of at less than 0.5 mm.
A steam buffer for a steam engine system to store generated steam energy and release energy to produce steam to the steam engine, comprising a high temperature connection for steam, a low temperature connection for water, a number of flow channels extending from said high temperature connection to said low temperature connection, said flow channels formed in a pressure resistant material having a melting point higher than an operating temperature of the steam buffer, and said flow channels having a very small diameter.
