FIELD: machine engineering.
SUBSTANCE: device for feeding gas and air to the burner for burning low-calorie and contaminated fuel contains a cylindrical mixing chamber of gas and air flows and a swirler with blades, the swirler blades are installed with formation of alternating channels so that, one channel is formed for gas flow and adjacent channel is formed for air flow. The channels formed for gas flow are made for connecting to gas supply manifold, and adjacent channels are connected with air supply manifold.
EFFECT: increased intensity when mixing large volumes of low-calorie contaminated gases with air.
