The invention relates to combined burner units of vortex type for alternative or simultaneous burning of coal-water and gas fuel. In the body of the burner there are arranged a flame front generator separated by partition from the muffle cavity, with placed in it a gas burner and a gas-air mixer arranged as conical ring formed with at least two conical segments displaced with respect to its axis, an injector for supply of dust-coal mix and gas burner with gas distribution collector installed along generatrix of conical segments. The burner is equipped with box for air supply with tangent swirler and cooling jacket with spiral-like baffle wall inward the cavity. The design provides quick heating of muffle walls, quick evaporation of moisture in drops of coal-water suspension and following effective burning in furnace. |
