FIELD: power engineering.
SUBSTANCE: invention can be implemented for combustion and complete thermal neutralisation of various gas fuels, including ballasted gases containing solid (dust-like) combustible impurities together with natural gas or without it in combustion chambers of heat power plants or industrial furnaces. The installation for fuel combustion consists of air supplying duct and of coaxially arranged the central channel of auxiliary fuel supply, middle channel with vortex blades of secondary air supply, and of a chamber mixing primary air and gas with low combustion heat. The installation also has an outlet nozzle, while tangential nozzles for supply of primary air into the mixing chamber are uniformly distributed along circumference in the air supplying duct. Also diametre of the middle channel is 0.55-0.65 of diametre of the output nozzle of the installation. Amount of the tangential nozzles is not less, than eight.
EFFECT: increased operational reliability of installation.
