Secondary burning method and special energy-saving furnace for organic-fuel firepot of two-way air blower

[0024] The secondary combustion method of the two-way blast organic fuel furnace is as follows: the organic fuel is chaff, and a row of firewood can also be placed on the top of the chaff in order to prevent the dust from just being ignited. The firewood is adjusted to just touch the air inlet of the burner head, and the combustion chamber is composed of the fire distribution ring and the fire distribution plate in the burner head above the air inlet of the burner head; the charcoal is filled to 1 / 2 height in the fire distribution ring, and a small piece of charcoal Light it as a fire and put it into the combustion chamber, fill the combustion chamber with charcoal, and cover the fire distribution board; turn on the blower to generate two-way blast, and the blower blows through the annular air inlet channel all the way to add oxygen to the charcoal to make it fully burnt. At the same time, the chaff in the furnace is decomposed to produce hydrocarbon gas; the blower blows air to

[0035] Embodiment 2: The furnace body 2 of the special energy-saving furnace is made of refractory material or filled with refractory material between the double-layer furnace body, and the water inlet and outlet devices are omitted. Others are similar to Example 1.
