TURBULENT FLOWS MEASURING Russian patent published in 2018 - IPC F23N1/02 F23N5/18 F23D14/60 

FIELD: power engineering.

SUBSTANCE: invention relates to the power engineering. Combustion plant includes burner (1) and combustion chamber (2), side channel (28) and supply channel (11) connected to burner (1) through the fluid, having connection (12) for side channel (28), at least one inlet (27) and outlet, said at least one inlet (27) of supply channel (11) being configured to flow into supply channel (11), wherein said discharge of supply channel (11) is adapted to discharge fluid from supply channel (11) to burner (1) of said combustion plant, side channel (28) comprising mass flow sensor (13), inlet, outlet and at least one flow resistance element (14), the inlet of side channel (28) being connected to connection point (12) of supply channel (11) in such a way that side channel (28) and supply channel (11) are connected by fluid, mass flow sensor (13) being configured to determine a signal corresponding to mass flow (15) of the fluid through side channel (28), wherein said at least one flow resistance member (14) divides the side channel into a first portion facing mass flow sensor (13) and a second portion facing away from mass flow sensor (13), and has a through passage area for passing a fluid between these first and second portions, this combustion plant has an outer region located outside side channel (28) and supply channel (11), and burner (1), and combustion chamber (2), mass flow sensor (13) protrudes into side channel (28), and the outflow of side channel (28) is adapted to flow fluid from side channel (28) directly into combustion chamber (2) or directly into said outer region.

EFFECT: invention makes it possible to improve flow measurement in combustion plants in the presence of turbulence.
