1. , the burner of the steady flame of premix is sprayed in the staggered current-sharing of a kind of air-flow annular, include cylinder (8), coal gas distributes circuit (2a) and air to distribute circuit (2b), it is characterized in that, cylinder (8) is made of exterior wall (1) and the interior wall (11) that moves up and down, exterior wall places on the supporting ring flat-plate (9), interior wall adopts labyrinth sealing to be connected (10) with exterior wall and links together, being provided with coaxial cross section in cylinder (8) exterior wall (1) is the ring-type rectangle circuit of rectangle, by inclination partition wall 2C the circuit symmetry is divided into two chambers up and down in the rectangle circuit, upper chamber is that coal gas distributes circuit (2a), lower chambers is that air distributes circuit (2b), two circuits all are the chamber circuit that progressively shrinks inside gas outlet, there are gas inlet pipe (6) and air intlet pipe (7) to insert respectively in the outer end, place, maximum cross-section of distributing circuit separately, distribute the upper inner of circuit and air to distribute the lower inside of circuit to draw jet for gas pipe (3a) and the air nozzle pipe (3b) that is interspersed along circumferential ring-type respectively at coal gas, jet for gas pipe (3a) and air nozzle pipe (3b) are in the cylinder body wall and parallel with its axis, and number respectively is 20~

  • 40;

    Jet for gas pipe (3a) and air nozzle pipe (3b) are drawn by the upper surface respectively in cylinder, form the jet for gas and the air nozzle of ring-type interlaced arrangement, jet for gas with have above the air nozzle be connected by interior wall and exterior wall top between the coaxial annular premixed conduit (4) that constitutes, be equipped with the current-sharing that the faces nozzle-choked flow link stopper (5) of equilateral triangle on the annular premixed conduit (4).
