1. Förfarande för regiering av förbränning av material i en förbränningsugn (1) med fluidiserad bädd, vilken 5 ugn omfattar: ett förbränningsrum, i vilket en fluidiserad bädd (2) bildas; ett i förbränningsrummets nedre parti anordnat luftkammarmedel (6) för bläsning av luft uppät in i för-10 bränningsrummet i avsikt att bilda en fluidiserad bädd; ett lufttillförselmedel (5) för inmatning av luft i luftkammarmedlet; ett luftinloppsmedel (8) som utmynnar i förbrän-ningsrummet ovanför den fluidiserade bädden; och 15 detektormedel (14-1) för detektering av en tili förbränningshastigheten anslutande faktor, vilken faktor är vilken som heist av följande parametrar: temperaturen i förbränningsrummet, trycket i förbränningsrummet, mäng-den material, klarheten i förbränningsrummet och rökgasens 20 syrehalt eller en blandning av dessa faktorer, kännetecknat av att förfarandet omfattar föl-jande steg: mängden luft som inmatas frän lufttillförselmedlet (5) tili luftkammarmedlet (6) minskas dä den detekterade • 25 faktorn visar att förbränningshastigheten överstiger en förutbestämd nivä, och en luftmängd som motsvarar den re-ducerade luftmängden inmatas samtidigt i förbränningsrummet via luftinloppsmedlet (8); och mängden via lufttillförselmedlet (5) inmatad luft 30 äterförs tili sitt ursprungliga värde och inmatningen av via luftinloppsmedlet inmatad luft avslutas dä nämnda faktor visar att förbränningshastigheten minskat tili ett värde under nämnda förutbestämda värde för regiering av förbränningshastigheten och för upprätthällning av densam-35 ma pä nämnda förutbestämda nivä. 93673 30
2. Förfarande enligt patentkrav 1, i vilket luft-kammarmedlet omfattar flera luftkammare, k ä n n e -tecknat av att minskningen av luftmängden utförs i en given luftkammare som befinner sig pä det ställe där 5 materialet inmatas i ugnen.
3. Förfarande enligt patentkrav 1 eller 2, där ugnen är försedd med ett sekundärt luftinloppsmedel (18), kännetecknat av att en luftmängd som motsvarar den minskade mängden inmatas i förbränningsrummet via 10 luftinloppsmedlet (8) och via det sekundära luftinlopps-medlet (18) när tillförseln tili luftkammarmedlet minskar.
4. Förfarande enligt patentkrav 3, kännetecknat av att faktorn indikerar den inne i ugnen (1) rädande klarheten, vilken detekteras av nämnda detek-15 tormedel (14-1), som omfattar ett klarhetsdetekteringsme-del anordnat ovanför det ställe där sekundärluft bläses in i förbränningsrummet med hjälp av det sekundära luftinloppsmedlet (18).
