Power burner, preferably jet burner, for low-emission combustion of coal dust in power boilers tangentially fed

摘要

the energy, especially coal dust combustion jet, to low-carbon energy boilers fuelled tangencjonalnie, equipped with pyu0142oprzewu00f3d, combined with a proszkuju0105cym solid fuel in particulate, nozzles, nozzle secondary air nozzles embedded in the spinal particulate pollutants, secondary air nozzle touching, upper air nozzles dopalaju0105cego, characterized by that,that combined with outlet mill wentylatorowego (m) pyu0142oprzewu00f3d (6), transporting the mixture of dust with a carrier are connected permanently at an angle 90 degrees channel section (13) and a section of horizontal vertical (16) equipped with three cascade favourably 'p u0142ytowych (171, 172, 173), which distance is from 0.5 to 0.75 width mutual vertical channel section (16),the handlebars warmers (171, 172, 173) are situated radius in relation to the one wall section of the vertical channel (16) and differentiated from her distance, rising up the cascade and the angle (? 1) the deviation leading 'warmers (171, 172, 173) from the vertical wall section of a channel (16) is included in the range of degrees - 40 degrees,in addition, in parallel to the inside wall of a horizontal segment (13.) and root canal vertical section (16) is a complementary shaped, composed of a horizontal segment (14) of solid material and the vertical section (15) of a material perforowanego, combined angle of 90 degrees, from the channel bottom (12) pyu0142omieszaniny dense, pou0142u0105czon y of panting pyu0142owu0105 main (11),situated in the lower part of the column palnikowej (18) pointing left down and together with the horizontal axis angle (? 2) from 104 degrees - from situated in horizontal axis channel upper (13) pyu0142omieszaniny rozrzedzonej, whose outlet is connected axially with panting record damping (10) attached horizontally in the upper part of the column palnikowej (18),the upper inlet channel (13) is located on the cascade has three 'warmers (171, 172, 173), and the distance between the lower edge of the vertical section of the perforowanego partitions (15) and the last wheel company (173) cascade is from 0.5 to 0.75 private okou015bci root canal vertical section (16),besides, the vertical section of partitions (15) is equipped with a uniform rectangular shaped openings arranged in vertical rows, preferably in three rows, separated at a distance a side rectangular aperture, moreover in the exit nozzle (pyu0142owej main 11) is a deflector (1),and the exit nozzle pyu0142owej drop (10) is a deflector (2), whereby the inside of the deflector plate (1, 2) are embedded respectively axially nozzle secondary air (4) and the spinal air nozzle (5), spinal deflected left down angle (beta) from 5 - degrees,besides, on the external side of the secondary air nozzle core (4) are double internal air nozzle (8) inclined down angle (? 1) in the range 10 degrees - 30 degrees equal to the angle deviation pyu0142owej main nozzle (11), and on the outside of the secondary air nozzle (5) is placed a second spinal double nozzle air external (7),inclined down angle (? 2) in the range 5 - 15o, moreover, panting pyu0142owu0105 damping (10) situated in the horizontal axis, is installed, the upper nozzle dopalaju0105ca (3) secondary air, uchylna for angle (? 3) + / - 15o.
