The specific embodiment

Be illustrated in conjunction with the accompanying drawings and embodiments.

(camber line among the figure on the shell is a sealing wire, and other dotted line is the internal structure line) as shown in the figure.This boiler design is the hot air boiler of three return duct of tool three backhaul conductive thermal exchange.One backhaul of described three backhauls is a boiler furnace 1, two return has 3 return duct 2-2, three backhauls have 2 return duct 2-3, the left end of described two, 3 two backhauls is trapezoidal left fume chamber 3 and encloses and cover, right-hand member is then separately enclosed by two rectangle fume chambers and covers, below one for enclosing the bottom right fume chamber 4-1 that covers 3 return duct 2-2 of two return, above one for enclosing the upper right fume chamber 4-2 that covers 2 return duct 2-3 of three backhauls.

At the left part of stove, boiler mouth 1-1 is set, on the top of stove air blast 6 is installed, the blast pipe 7 of this machine is put in the stove by fire door 1-1 and blows.Traverse total length by the combustion chamber 1 that the fire door 1-1 of boiler begins to design from left to right, the furnace wall is provided with two layers, is the concentric double-walled insulation boiler of a reducing, can guarantee the heat preservation hot exchange, and the effect of conduction thermal-arrest is had the effect of Environmental Safety again.Leading smoke pipe 5 and enclosing the bottom right fume chamber 4-1 that covers 3 return duct 2-2 of two return and be connected of this combustion chamber one side double-walled passed by being located at right part in described combustion chamber 1, lead smoke pipe 5 by this, conduction from left to right after 1 burning of flue gas spontaneous combustion chamber, lead 5 of smoke pipes to this and change bottom right fume chamber 4-1 commentaries on classics over to by conducting heat exchange from right-to-left, after arriving left fume chamber 3 again, because of being enclosed covert's limit by left fume chamber 3 sealings, flue gas then changes by 2 return duct 2-3 from three backhauls and conducts heat exchange from left to right, arrives the upper right fume chamber 4-2 that encloses 2 return duct 2-3 that cover three backhauls.Upper right quarter at stove is equipped with air-introduced machine 8, this air-introduced machine 8 is connected with described bottom right fume chamber 4-1 by guide duct 10, opening in upper right fume chamber 4-2 one side connects induced duct 9, after making air-introduced machine 8 introduce cold wind, enter through induced duct 9 by the air-introduced machine exhausting, carry out heat exchange through upper right fume chamber 4-2 to bottom right fume chamber 4-1 loopback, conduction, and control furnace temperature temperature, guarantee that hot blast temperature keeps certain value.Be provided with warm air discharge tubes 11 on the bottom surface of upper right fume chamber 4-2, make above-mentionedly through burning, the hot blast that conduction is assembled after the heat exchange is expelled to drying room through this warm air discharge tubes 11, and heat supply gas applying unit is used.Utilize this hot blast can realize that the charing of the drying of timber, degreasing, setting and slight, moderate, the degree of depth and other cure roasting baking, the usefulness of drying.For ease of transportation, on the bottom surface of boiler jacket 14, be provided with support bracket 12, return pulley 13 is installed, so that transportation is moved on this support 12.
