Reciprocating grate
The grate is air cooled and divided into three to five zones per lane with one to three lanes in total. The grate bars’ speed and the primary air supply are regulated for each grate zone individually. The individualized control of each zone offers an optimized combustion. The grate bars are made of high-alloyed cast steel and supplied pre-mounted. The grate is function tested before delivery.
