arrangement for standardizing the powdered solid matter feed from a concentrated material burner of a suspended material melting furnace or suspended material conversion furnace

摘要

arrangement for uniformising powdered solid matter feed from a concentrated material burner of a suspended material melting furnace or suspended material conversion furnace. The present invention provides an arrangement for feeding powdered solid matter into a concentrated material burner (2) of a suspended material melting furnace or a suspended material conversion furnace (1). the concentrated material burner (2) comprises a reaction gas feed device (6), a powdered solid matter feed device (3) and a concentrated material dispenser (7). The arrangement comprises a first powder solids discharge tube (8) for feeding the powder solids into the powder solids feed device (3) of the concentrated material burner (2). the first powdered material discharge pipe (8) is provided with a first division (10) which divides the solid material so as to divide the first solid material discharge pipe (8) into two parts of the pipe substantially similar discharge lines (11). the powdered solid matter feed device (3) of the concentrated material burner (2) comprises a concentrated material annular discharge channel (4) surrounding the concentrated material distributor (7) of the concentrated material burner. each discharge pipe portion (11) of the first solid powder discharge pipe (8) is at least partially divided into two discharge pipe portions (12) through a second division (13).
