[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution: a novel combustion furnace furnace body, including: a furnace body main body 1, which is formed by cutting, bending, and welding steel plates;

[0025] The furnace main body 1 includes three sloped combustion walls 2 arranged in a U shape. The sloped combustion walls 2 enclose a bucket-shaped combustion trough, and the middle sloped combustion wall 2 is provided with a feed port 21 and an ignition port 22. Both the feed port 21 and the ignition port 22 penetrate through the rear wall of the furnace main body 1.

[0026] The left and right symmetric sloped combustion walls 2 are both provided with firewood combustion zone air holes 23 and particulate matter combustion zone air holes 24, dividing the entire combustion trough into two areas: firewood combustion and particulate matter combustion.

[0032] Working principle: The combustible platform plate 3 is placed into the combustion trough and is suspended and fixed by being stuck on the sloped combustion wall 2. The particulate combustibles enter through the feed port 21 and fall on the combustible platform plate 3, and are ignited by inserting an ignition device through the ignition port 22. Air enters the particulate matter combustion zone air holes 24 through the air inlet box 5 to provide oxygen for the particulate combustibles.

[0033] The firewood is directly placed on the combustible platform plate 3 and ignited. Air enters the firewood combustion zone air holes 23 through the furnace door 4 to provide oxygen for the firewood combustion.

[0034] The generated combustion slag falls into the lower space of the furnace main body 1 through the particulate matter combustion slag discharge holes 31 and the firewood combustion slag discharge holes 32, and is cleaned through the furnace door 4.

[0035] This furnace can burn particulate combustibles and firewood simultaneously or separately, and is configured with different air ducts to adapt to the oxygen requirements of different combustibles.
