Abstract
Sposób rozpylania suspensji zwłaszcza paliwowych w palnikach polega na tym, że do palnika (10) w palenisku dopływa pod wysokim ciśnieniem suspensja rozdrobnionego paliwa stałego w cieczy, którą podgrzewa się w nagrzewnicy suspensji (3) do temperatury zbliżonej do temperatury nasycenia cieczy i rozpręża się w dyszy suspensji (7) w palniku (10) do ciśnienia w palenisku a wytworzona podczas rozprężania para nasycona rozprasza cząsteczki paliwa, które tworzą zawiesinę drobin paliwa stałego w parze mokrej cieczy, przy czym zawiesina drobin paliwa w parze mokrej po jedno lub wielostopniowym zmieszaniu z gorącym gazem z utleniaczem w koncentrycznych dyszach (8, 9) palnika (10) tworzy mieszankę palną a po zmieszaniu z gorącym gazem bez utleniacza w koncentrycznych dyszach (8,9) tworzy warunki do suszenia mieszanki. Instalacja przepływowa do rozpylania suspensji zwłaszcza paliwowych w palnikach z dyszą charakteryzuję się tym, że zbiornik (1) do gromadzenia suspensji paliwowej połączony jest rurociągiem (4) z wysokociśnieniową pompą suspensji (2) następnie z nagrzewnicą suspensji (3) i dyszą suspensji która wyposażona jest w dławieniowy zespół rozprężania suspensji złożony z dyszy suspensji (7) i grzyba zaworowego (6) z siłownikiem napędowym (5) a za dyszą do rozpylania suspensji (7) zabudowane są koncentryczne dysze (8 i 9) wielostopniowego mieszacza połączone oknem (11-2) z paleniskiem i kanałem (11-1) z nagrzewnicą (12) a następnie kanałem (13) korzystnie z maszyną przepływową (14) indukującą przepływ gazu z utleniaczem do palnika (10) również korzystnie z maszyną przepływową (14) indukującą przepływ gazu bez utleniacza w instalacji suszarniczej suspensji.The method of spraying suspensions, especially fuel ones, in the burners is based on the fact that the suspension of particulate solid fuel in a liquid flows under high pressure to the burner (10) in the furnace, which is heated in the suspension heater (3) to a temperature close to the liquid saturation temperature and expands in the suspension nozzle (7) in the burner (10) to the pressure in the furnace, and the saturated steam generated during expansion disperses fuel particles that form a suspension of solid fuel particles in a wet liquid vapor, while the suspension of fuel particles in wet vapor is mixed with hot steam in one or more stages gas with an oxidant in concentric nozzles (8, 9) of the burner (10) forms a combustible mixture, and after mixing with hot gas without oxidant in concentric nozzles (8,9) it creates conditions for drying the mixture. The flow system for spraying suspensions, especially fuel ones in burners with a nozzle, is characterized by the fact that the tank (1) for collecting the fuel suspension is connected by a pipeline (4) with a high-pressure suspension pump (2), then with a suspension heater (3) and a suspension nozzle which is equipped with the throttle suspension expansion unit, consisting of a suspension nozzle (7) and a valve plug (6) with a drive actuator (5), and behind the suspension spraying nozzle (7), concentric nozzles (8 and 9) of the multi-stage mixer connected by a window (11-2) are installed ) with a furnace and a channel (11-1) with a heater (12) and then a channel (13) preferably with a flow machine (14) inducing gas flow with the oxidant to the burner (10) also preferably with a flow machine (14) inducing gas flow without oxidant in the suspension drying installation.
