Abstract

The combustion method uses a moving combustion grid with a number of baffle elements (10) supported by the top surfaces of the grid plates (1-4), for deflection of the primary combustion air supplied to the combustion bed via the combustion grid. An Independent claim is also included for a moving combustion grid for solid fuel combustion.
