Abrégé

The invention relates to a combustion air cassette (10) for conveying combustion air to different height levels of a furnace in a fireplace. The combustion air cassette (10) comprises a hollow primary air cassette (11) and at least one hollow secondary air cassette (12) with an air flow connection to the primary air cassette (11), and an air intake (35). Via the air intake (35), combustion air is arranged to flow into the primary air cassette (11) and further to the lower part of the furnace, below a wood charge to be placed on top of the primary air cassette (11), via primary air inlets (15); as well as into at least one secondary air cassette (12), to be preheated, and from which secondary air cassette (12) preheated secondary air is arranged to flow into the furnace, at least via secondary air inlets (16) provided at the height of the upper combustion space of the wood charge burning on the primary air cassette (11). The invention also relates to a fireplace (50) comprising a combustion air cassette (10), a method for introducing combustion air to a wood charge burning in the furnace of the fireplace, to different height levels of the furnace, by the combustion air cassette (10), as well as a retrofitting kit for a combustion air cassette.

The invention relates to a secondary air casing (10) for conducting secondary air to different heights inside a firebox of a fireplace. The casing (10) comprises a hollow body, an air inlet (11) through which air is arranged to be flown inside the secondary air casing (10) to be preheated, and a plurality of air outlet openings (12) arranged in different heights of the secondary air casing (10) arranged to conduct preheated air to the firebox through at least the air outlet openings (12) that are on the height of the top of a burning wood charge inside the firebox. The invention further relates to a fireplace comprising a secondary air casing (10) and a grate (10), a method for supplying a secondary air to different heights of a firebox through air outlet openings (12) arranged at different heights on a secondary air casing (10), and to a secondary air casing retrofitting kit for a fireplace.
