Abstract
Sposób przygotowania zawilgoconego wegla brunatnego do spalania w kotle energetycznym charakteryzuje sie tym, ze rozdrobniony do ziaren o frakcji do 50 mm wegiel brunatny o wilgotnosci w zakresie od 30% do 60% wprowadzany jest do obracanej z predkoscia od 0,5 do 10 obr./min. komory obrotowej (1), w której przesypywany w kierunku wylotu z predkoscia w zakresie od 0,005 m/s do 0,05 m/s w przedziale czasu od 1 do 30 minut ogrzewany jest wspólpradowo strumieniem gazu suszarniczego o temperaturze w zakresie od 100 do 600°C przy zawartosci tlenu do 15% udzialu objetosciowego i cisnieniu do 70 Pa, opuszczajacy komore obrotowa (1) podsuszony wegiel brunatny kieruje sie do zmielenia w zespole mlyna weglowego (16), przy czym korzystnie przed zmieleniem podsuszony wegiel brunatny miesza sie z surowym weglem brunatnym a wychodzacy z komory obrotowej (1) zawilgocony i zapylony gaz suszarniczy kieruje sie do odpylenia do ukladu odpylajacego (18) a nastepnie do schlodzenia i osuszenia w ukladzie schladzajaco-osuszajacym (21). Urzadzenie do przygotowania zawilgoconego wegla brunatnego do spalania w kotle energetycznym zbudowane z komory obrotowej (1) z pólkami zgarniajacymi (1.1) przesypujacymi wprowadzony do komory obrotowej (1) wegiel zamknietej od przodu komora wytwarzania gazu suszarniczego (2) wyposazona w palnik (8) na paliwo plynne albo gazowe oraz kolektor (9) doprowadzajacy do komory wytwarzania gazu suszarniczego (2) spaliny a od tylu komora zbiorcza (3) produktów suszenia, polaczonego z komora zbiorcza (3) poprzez uklad odpylajacy (18) ukladu schladzajaco osuszajacego polaczonego rurociagiem (22) z kolektorem (9) oraz wyposazonego w zasobnik (6) podajnika (5) wegla do komory obrotowej (1) charakteryzuje sie tym, ze pod lejem zsypowym (3.4) komory zbiorczej (3) zainstalowany jest podajnik celkowy (15) transportujacy podsuszony wegiel do usytuowanego przy nim zespolu mlyna weglowego (16), przy zasobniku (6) podajnika (5) wegla do komory obrotowej (1) umiejscowiona jest kruszarka (7) wegla wprowadzanego do zasobnika (6) a kolektor (9) polaczony jest rurociagiem (23) z oknem poboru (24.1) goracych spalin z kotla energetycznego (24).The method of preparation of moistened brown coal for combustion in an energy boiler is characterized by the fact that brown coal crushed to grains with a fraction of up to 50 mm with humidity in the range from 30% to 60% is fed to a rotated speed of 0.5 to 10 rpm min. rotary chamber (1), in which it is poured towards the outlet with a speed in the range from 0.005 m / s to 0.05 m / s in a time interval from 1 to 30 minutes is co-heated with a stream of drying gas at a temperature in the range from 100 to 600 ° C with oxygen content up to 15% by volume and pressure up to 70 Pa, leaving the rotary chamber (1) the dehydrated brown coal is directed to milling in the coal mill unit (16), preferably the pre-dried brown coal mixed with raw brown coal and the moist and dusty drying gas coming out of the rotary chamber (1) is directed to dust removal to the dedusting system (18) and then to cooling and drying in the cooling-drying system (21). A device for the preparation of moist brown coal for combustion in an energy boiler built from a rotary chamber (1) with scraping shelves (1.1) pouring into the rotary chamber (1) coal closed from the front of a drying gas production chamber (2) equipped with a burner (8) on liquid or gaseous fuel and a collector (9) supplying to the drying gas production chamber (2) flue gas and from the rear collecting chamber (3) of drying products, connected to the collecting chamber (3) through a dedusting system (18) of a cooling and drying system connected by a pipeline (22) ) with a collector (9) and a feeder (5) equipped with a hopper (5) coal into the rotary chamber (1) is characterized by the fact that under the hopper (3.4) the collecting chamber (3) a cell feeder (15) is installed to transport the dried coal the coal mill (16) located next to it, at the feeder (6) of the coal feeder (5) into the rotary chamber (1) there is a crusher (7) to the storage tank (6) and the collector (9) is connected by a pipeline (23) with the intake window (24.1) of hot flue gases from the power boiler (24).
