提出采用塔式“T”型炉膛布置方案系列,将中温离心式旋风分离器分别布置于两侧,采用Ahlstr(?)m裤衩管,同时将回料点、斜炉底“L”型风帽作同一旋向布置,炉膛上部的上二次风及下二次风都采用切向分级燃烧技术,使更多的细颗粒在床内燃尽,提高床内介质的传热系数和燃烧效率,力求进一步降低NO_x排放量,为开发新颖的第三代循环流化床燃烧技术作了有益的探讨。 It is proposed to adopt a series of tower “T” arrangement of furnaces, the middle temperature centrifugal cyclones are respectively arranged on both sides, the Ahlstr (?) M pants tube is used, and the material return points and the “L” In the same direction of rotation, the upper secondary air and the lower secondary air in the upper part of the furnace adopt the tangential staged combustion technology, so that more fine particles are burnt up in the bed and the heat transfer coefficient and combustion efficiency of the bed medium are improved Reduce NO_x emissions, and make a useful discussion on the development of a novel third-generation CFB combustion technology.
