METHOD AND DEVICE FOR HEAT ENERGY TRANSFER BY MATERIALS, CHANGING ITS PHYSICAL STATE Russian patent published in 2017 - IPC F28D21/00 F28F23/00 

FIELD: heating system.

SUBSTANCE: device is installed in contact with the exhaust gases (2) inside the enclosing chamber (22) or inside one or more pipes, related to the installation on which the manufacturing or auxiliary processes are carried out. The device contains at least two sections (4), each equipped with at least one heat exchange module (5), having the heat exchanger (6), which is at least partially in contact with the exhaust gases (2) for the purpose of heat energy exchanging. The first material (7) provided, changing its physical state, is located inside the mentioned heat exchanger (6). The provided extraction heat exchanger (8) is in contact with the mentioned first material (7), changing its physical state, equipped with the supply and recirculation pipes (9), in which the heat-carrying fluid (10) circulates. In addition, the displacement facilities (14, 15) are provided for conveying the heat-carrying fluid (10) and controlling of its flow rate for selective assignment for each section (4) of the heat flow values versions, extracted from the exaust gases (2) and participating in the heat exchange with the first material (7), changing its physical state.

EFFECT: efficient extraction of the heat energy from the exhaust gases and supply of constant heat flow to the consumer.
