Abstract

Özellikle yanıcı maddelerin ateşlenmesi için, içinde akışkanlaştırılmış katı parçacıklar bulunan bir yatağa sahip bir yanma odasından (2) ve yanma odasının (2) alt kısmından çıkan kül veya katı maddenin (13) soğutulması için yanma odasına (2) bağlı bir katı madde soğutucusundan (3) oluşan, bu arada soğutucunun (3) soğutulacak katı maddenin (13) yatay bir akışla içinden geçmesi için en az bir akışkan odacıktan (4, 5, 6) oluştuğu, bu arada her akışkan odacığın (4, 5, 6) bir alt kısma (10) ve soğutucunun akışkan yatağının (35) üst tarafında yer alan ve söz konusu akışkan odacıklarla (4, 5, 6) gaz ve katı madde ile ilgili olarak ilişki içinde olan bir serbest alana (11) sahip olduğu, soğutucunun (3) ayrıca parçacıkların akışkan odacıkta veya odacıklarda (4, 5, 6) akışkanlaştırılması için her alt kısma (10) akışkanlaştırma gazının (12) iletilmesi için bir araca; akışkanlaştırma gazının (12) serbest alandan (11) yanma odasının (2) alt kısmına gönderilmesi için bir en az bir çıkış deliğine (14); külün (13) akışkan yatak ateşlemesinin tabana yakın kısmından soğutucuya (3) iletilmesi için birinci akışkan odacığı (4) yanma odasının (2) alt kısmıyla bağlayan en az bir giriş deliğine (15) ve katı maddenin (13) soğutucudan (3) çıkışı için sonuncu akışkan odacıkla (4, 5, 6) bağlantılı en az bir çıkış deliğine (16) sahip olduğu 20 dolaşımlı akışkan yataklı reaktör olup, bu arada soğutucunun (3) serbest alanında (11) çıkış deliği (14) yönünde akan ve katı parçacıkları (13) içeren akışkanlaştırma gazından (12) katı parçacıklarını (13) ayırmak ve ayrılan katı maddelerin (13) akışkan odacıklara (4, 5, 6) geri iletimi için en az bir ayırıcı (30) yer alır.Particularly for igniting combustible materials, a combustion chamber (2) having a bed with fluidized solid particles and a solids cooler (3) connected to the combustion chamber (2) for cooling ash or solid material (13) exiting from the underside of the combustion chamber (2). ), wherein the refrigerant (3) comprises at least one fluid chamber (4, 5, 6) so that the solid material (13) to be cooled passes through a horizontal flow, while each fluid chamber (4, 5, 6) has a lower portion. (10) and the refrigerant (3) having a free space (11) located on the upper side of the fluid bed (35) of the refrigerant and in relation to said gas and solid material with said fluid chambers (4, 5, 6). a means for delivering fluidizing gas (12) to each lower portion (10) for fluidizing the particles in or in the fluid chamber (4, 5, 6); an at least one outlet orifice (14) for supplying the fluidizing gas (12) from the free space (11) to the bottom of the combustion chamber (2); for transmitting the ash (13) from the proximal portion of the fluidised bed ignition to the cooler (3) to the at least one inlet orifice (15) connecting the first fluid chamber (4) with the lower part of the combustion chamber (2) and to exit the solid material (13) from the cooler (3). the circulating fluidized bed reactor 20 having at least one outlet orifice (16) associated with the last fluid chamber (4, 5, 6), while flowing and solid particles flowing in the free space (11) of the refrigerant (3) in the direction of the outlet orifice (14). At least one separator (30) is provided for separating the solid particles (13) from the fluidizing gas (12) containing and for returning the separated solids (13) to the fluid chambers (4, 5, 6).
