METHOD AND DEVICE FOR MEASURING CHANGES IN THE MASS OF HEAT EXCHANGERS OF A STEAM BOILER Russian patent published in 2023 - IPC F22B37/56 

FIELD: heat exchangers.

SUBSTANCE: method for measuring changes in the mass of a group (1, 2, 3) of heat exchangers or heat exchangers from the group in a steam boiler, each heat exchanger (4) of which is supported by means of hanging rods (7) to support beams (5, 8) above the steam boiler differs in that that at least one suspension rod (7) of at least one heat exchanger (4) is connected to the lower measuring element (9) and the upper measuring element (10) and changes in the measuring distance (X) between the measuring elements (9, 10) are measured by means of a measuring unit (15) connected between the measuring elements (9, 10) for measuring changes in the mass of the heat exchanger (4). The measuring unit (15) is preferably fixed between the measuring elements (9, 10), and the change in the measuring distance (X) is measured by deforming the measuring unit (15). The connecting element (11), which is parallel to the suspension rod (7), is preferably located between the measuring elements (9, 10), while the specified connecting element (11) ensures that the change in distance is transmitted to the measuring unit (15). The elastic element (16) is fixed between the measuring element (9) and the upper measuring element (10).

EFFECT: measuring method is proposed.
