The invention discloses a
combustion furnace with a conveniently cooled
smoke exhaust tube. The
combustion furnace comprises a bottom plate. A boiler body is fixed to the outer wall of the top of thebottom plate through bolts, a
smoke exhaust
barrel is fixed to the outer wall of the top of the bottom plate through bolts, a
heat conducting plate is fixed to the outer wall of one side of the smokeexhaust
barrel through bolts, a stable rib plate is fixed to the outer wall of one side of the
smoke exhaust
barrel through bolts, the outer wall of one side of the stable rib plate is welded to the outer wall of the top of the bottom plate, a horizontally placed transverse plate is welded to the outer wall of one side of the smoke exhaust barrel, and a water tank is fixed to the outer wall of thetop of the transverse plate through bolts. The
combustion furnace disclosed by the invention can cool the smoke exhaust barrel simply and effectively. The
heat conducting plate exchanges heat with the outer side, and a
water flow in the water tank is sprayed by means of a
shower nozzle to absorb heat and be evaporated to take away part of heat, so that the
cooling effect of the device is obviousin effect, and
impurity particles of smoke passing a filter screen are filtered. Meanwhile,
soot in the smoke is wet and falls in a humid environment in the smoke exhaust barrel, so that the blockagecondition is reduced.
