Description
Jedynym zródlem ciepla w piecu obrotowym do wypalania klinkieru cementowego i podob¬ nych materialów jest dotychczas palnik na pyl weglowy, olej albo gaz. W poprawnie zaprojek¬ towanym piecu wydajnosc cieplna palnika jest dobrana do rozmiarów pieca. Przez zwiekszanie wydajnosci palnika mozna zwiekszac wydajnosc pieca tylko do pewnych granic, okreslonych wzgledami technologicznymi, na przyklad pogar¬ szaniem sie jakosci produktu, zmniejszeniem trwalosci okladtziny i zwiekszeniem strat ciepl¬ nych.Przedmiotem wynalazku jest zwiekszenie wy¬ dajnosci pieca, przez wprowadzenie nowego zródla ciepla.Osiaga sie to przez doprowadzanie do pieca surowca, zmieszanego w odpowiednim stosunku z paliwem na wzór zasilania pieców szybowych.Ten dodatek paliwa do surowca nie wymaga zmiany istniejacego sposobu zasilania pieca, mo¬ zna go wiec stosowac tak przy mokrej metodzie z wlewaniem mulu alibo z wtryskiem, jak i przy metodzie suchej. Dodatek paliwa moze pokry¬ wac cala potrzebna ilosc ciepla albo tez tylko jego czesc. Przy ilosci paliwa, zwykle w postaci drobno mielonego koksu albo chudego wegla ka¬ miennego, wystarczajacej do wypalenia, palnik bedzie sluzyl tylko do podgrzewania paliwa do temperatury zaplonu. Przy mniejszym dodatku paliwa brakujaca czesc ciepla dostarcza palnik.Sposób wypalania wedlug wynalazku uniezalez¬ nia calkowicie albo czesciowo wydajnosc pieca od wydajnosci palnika i umozliwia znaczne zwiek¬ szanie wydajnosci pieca, a wiec i obnizanie kosz¬ tów produkcji. PLUntil now, the only heat source in the rotary kiln for burning cement clinker and the like is a coal dust, oil or gas burner. In a properly designed furnace, the thermal efficiency of the burner is matched to the size of the furnace. By increasing the efficiency of the burner, it is possible to increase the efficiency of the furnace only up to certain limits, determined by technological considerations, for example, deterioration of the quality of the product, reduction of the durability of the lining and increased thermal losses. The object of the invention is to increase the efficiency of the furnace by introducing a new source of heat. This is achieved by supplying the furnace with the raw material, mixed in an appropriate ratio with the fuel, in the manner of feeding shaft furnaces. injection and the dry method. The addition of fuel may cover all or only a portion of the heat required. With sufficient fuel, usually in the form of finely ground coke or lean coal, sufficient to burn out the burner, the burner will only serve to heat the fuel to its ignition temperature. With less fuel addition, the missing part of the heat is supplied by the burner. The method of firing according to the invention makes the performance of the furnace wholly or partially independent of that of the burner, and allows a significant increase in the efficiency of the furnace and thus lower production costs.
