Abstract
To cool a grate having alternately fixed and movable rows (,′) of grate bars (,), cooling liquid is sprayed into cavities (,), open at the bottom, of the grate bars (,) from spray tubes (,) situated in the underblast region (,) and in the process vaporizes essentially completely, so that the heat of vaporization is extracted from the grate bars (,). The angle sector (,) into which the cooling liquid is sprayed may be set in such a way that in each case only those sections of the grate bars (,) whose top sides form the free surface of the grate are sprayed. The cavities may also be closed except for a discharge opening leading into the underblast region and may be connected to a supply reservoir, in which the liquid is kept at a constant level, which is just below the discharge openings.
