Abstract

A burner for gas burning relates to heat power engineering, to burning of gaseous organic fuel in combustion chambers of heat-power installations, in particular for burning pyrolysis gas in combustion chambers of boilers of gas-generator type. A burner for gas burning has body with a chamber for preparation of primary burning mix and burning zone, a channel for gas supply and channel for primary air supply that are connected to the chamber for preparation of primary burning mix, and channel for secondary air supply. Burning zone is divided into two arranged in sequence along the axis of the body burning sections: section of burning of primary burning mix and section for afterburning of combustion products of the primary burning mix. at that the channel for supply of secondary air is connected to the section of afterburning of burning products of primary burning mix. The channel for secondary air supply is connected to the section of afterburning of combustion products of primary burning mix. In the burning zone a stabilizer of burning is installed, this is arranged as a central rod, arranged along the axis of the body within boundaries of burning sections, and hollow cylinder, arranged in burning sections coaxially with the central rod with radial gaps between that and the body, and heat-capacity rings placed at the inlet and the outlet of the burning section of primary burning mix coaxially with the central rod. With the use of the burner provided is effective and stable process of combustion of gas variable in composition, for instance pyrolysis gas, in reactors of gas-generator type.
