(57) The invention relates to a burner for solid fuel, particularly for pellets, the burner
comprising a body (3') and a grate (4'). To enable burning of pellets with a clam
flame and yet at low emissions, the grate (4') comprises an oblique grate surface
(16a', 16b') defining an underlying air flow space (20') and an overlying fuel space
(19') extending all the way to the top end of the body (3'), the grate (4') extending
from a first end wall of the body (3') to a second end wall opposite to the first
one, the top end (10') of the grate comprising first air openings (13a', 13b') arranged
to extend in the longitudinal direction of the grate (4') from the first end of the
grate to the second end opposite to the first one, the air openings being formed so
as to allow flow of air from the air flow space (20') to the top end of the fuel space
(19'), and the grate (4') comprising second air openings (14a', 14b') arranged to
extend underneath the first air openings (13a', 13b') in the longitudinal direction
of the grate (4') from a first end of the bottom end (15') of the grate to a second
end opposite to the first one. The invention also relates to a furnace.
