METHOD FOR CO-COMBUSTION OF GASEOUS FUELS Russian patent published in 2022 - IPC F23D14/20 F23D17/00 

FIELD: energy.

SUBSTANCE: invention relates to the field of energy. The method includes supplying fuel of the second and first types to the second and first fuel lines of the multitorch burner and their sequential ignition. A multi-flare burner is used, equipped with the first and second horizontal mutually perpendicular gas pipes with perforated first and second gas collectors horizontally fixed in them perpendicular to their axes, in the holes of which flare tips are vertically installed, each of which contains an ejection mixer combined with the tip. In this case, initially, a second type of fuel is supplied through the second line and then, through the second gas pipe, a limited volume of second type fuel is supplied to the second gas collectors of the main multi-torch burner for low combustion. Then, using the pilot burner, the gas-air mixture is ignited, which enters through the ejection mixers of the torch heads of the multi-torch burner, mixed with air, obtaining the first torch. After the start of combustion of the first torch, the fuel of the first type is supplied to the first line of the main multi-torch burner and then through the first gas pipe to the first gas collectors of the main multi-torch burner, a limited amount of fuel of the first type for low combustion; after the fuel of the first type, supplied through the ejection mixers of the flare heads of the multi-flare burner, is mixed with air, the second torch is ignited with the help of the first torch, and the multi-flare burner is switched to high combustion by fully supplying fuel to the second and first fuel lines of the burner.

EFFECT: invention improves the efficiency of combustion of two types of fuel.
