sensors for items to be fired with a - »* plural cooling grates passed one after the other from the estate

The invention relates to a cooler for Iirenngut with a plurality of cooling grids passed one after the other by the material, whereby the cooling air of the first Itost sections can be fed into the kiln as combustion air *

With hel'anned rooters this aft is either only the cooling air from the first host section is fed to the furnace as secondary air or the mill air flows through it first of all the first üühle- · "section» around the »located there, hot good to quench, and then the second ÄÜhlerabschnitt to the furnace from there to be fed. In the first case the feeling -

These obstacles are also not removed by the disclosure system P 15.Ol 392, which shows a heat exchanger: for granular goods, in which the hosts passed by the goods one after the other are flowed through by the gaseous heat exchange medium. The heat exchanger shown there is because of de- "oil problems discussed nu ^ for heating the 1: suitable .öraigen good or to its Ab ^v ühlung of moderate temperatures.

Oe invention is based on the object, the Gesehilde-th Despite obstacles a cooler for combustion » to create well of the type mentioned at the beginning, of which Eost sections of the cooling medium can flow countercurrently through "* can"

The solution according to the invention consists in the combination the characteristics that

The "presence of the locks between the successive grate sections ermöglicht- it, in each case the sub-space of a preceding in liichtung the Gutsbewegung grate sections directly with the upper space of the following grate sections to connect" A particularly advantageous, compact design of the üühlers result, analogously to the mentioned publication, if more are arranged more than two host sections one above the other in a zigzag manner.

The facilities for introducing the water are expediently designed as spray elements that open into the upper space of the second grate sections »

The cooling in the first grate section and, in particular, sufficient cooling of the host in the highly stressed first part of this section as well as a deterrent of the material thrown from the furnace can be achieved if a first part of the first ilostab section is exposed to cold cooling air.
