本发明涉及一种用于具有至少一个炉篦轨道（1）的焙烧设备的炉篦，该炉篦轨道具有多个纵向交替的固定和移动的炉篦面对的排（3， 4），其特征在于，所述格栅衬里单元（11，12，13）在它们的后端与固定的或可移动的炉篦衬承载连接（6）和（用下面的炉篦内衬部11，12在其前端，位于13），并且其中所述冷却在通道 基本上横向于格栅的纵向方向布置。 炉篦的特征在于，所述冷却通道被布置曲折形，在炉篦内衬单元（11，12，13）嵌入的管（9），所述管间隔适于将炉箅衬里单元的热负荷。 优选地，从格栅覆盖单元（11,12,13）的后端到前端的管道节距正在减小。

The invention relates to a grate for a furnace having at least one grate track (1) with a plurality of alternating longitudinally on both sides of side walls (2) limited and with cooling channels, as well as feed and discharge lines (15, 16) provided fixed and moving grate-lining unit rows (3, 4), wherein the grate-lining units (11, 12, 13) are connected at their rear end with a fixed or movable grate-lining bearer (6) and with its front end on the following grate-lining unit (11, 12, lie 13), and wherein the cooling channels in the are arranged substantially transversely to the longitudinal direction of the grate. The grate is characterized in that the cooling passages meandering shape arranged in the grate-lining units (11, 12, 13) cast-in tubes (9), the tube spacing is adapted to the thermal loading of the grate-lining units. Preferably, the tube spacing is from the rear end to the front end of the grate-lining unit (11, 12, 13) decreasing.
