BURNER, WATER HEATING DEVICE INCLUDING SUCH BURNER, AND METHOD FOR CONTROLLING SUCH BURNER Russian patent published in 2024 - IPC F23D14/02 F24H1/00 F23N5/20 

FIELD: power engineering.

SUBSTANCE: burner includes a fuel supply portion configured to supply combustion reaction fuel to the combustion chamber, an air supply portion including a blower fan configured to supply combustion reaction air to the combustion chamber in accordance with its rotation, and a supply line air connected to the blower fan with the ability to supply air from outside to the blower fan, an ignition part configured to generate a spark to ignite the supplied fuel and air, a pressure data receiving part connected to the air supply pipeline with the ability to receive data of the pressure of the air supplied into the air supply part and a processor electrically connected to the air supply part and the pressure data receiving part, wherein the processor is configured to: control the blower fan so as to increase the rotation speed of the blower fan when the pressure value obtained by the pressure data acquisition part is less than the predetermined reference pressure value, wherein the fuel supply part includes: a fuel valve configured to determine the flow rate of fuel supplied to the combustion chamber in accordance with the pressure in the combustion chamber, and a pressure supply line communicating with an internal region of the chamber combustion and connected to the fuel valve with the ability to control the degree of opening of the fuel valve in accordance with the pressure in the combustion chamber.

EFFECT: ability to ensure stable combustion.
