The focus of boiler, in particular for domestic waste materials, a grid composed of alternately fixed and mobile bars a will - and - comes, regulating flexibility increased

摘要

The grid comprises, in its length, two successive layers 41, 42, with substantially the same slope generale, merging substantially plumb with the altar wall 7, each ply possessing its own movable frame 45d and 46d with its own control means 45, 46 and its own blowing box 43, 44, with its own means of ventilation. / p & & p & it thus becomes possible of the combustion conditions in the manner to optimize the carbonization mode on the upstream bed 41 and the brasier mode on the downstream bed 42.
