A steam or hot water generator, operating by solid fuels having high contents in volatile materials, provides that the column of fuel bears on an inwardly inclined grate. A fraction of the carbureting air passes through the grate and fuel, carrying along the volatile products. Another fraction of air, not passing through the grate and accordingly also not through the fuel, but which is however heated by travelling under the grate, joins with the fraction rich in volatile products which is still unburnt, bringing the latter to combustion.
