Further, expansion joint 6 is type metal expansion joint.
Further, the width of oblique flat board, two vertical plates and the first arc is 0.9~1.1 meter.
Further, the width of oblique flat board, two vertical plates and the first arc is 1 meter.
The beneficial effects of the utility model are：
Corner tube boiler accumulatingdust fluid structure of the present utility model by the structure type of rational modification convection heating surface,
Convection heating surface exports this part to body increases multiple oblique flat board, two vertical plates and arcs being arranged in juxtaposition；It is adjacent tiltedly flat
Connected between plate, adjacent upright flat board by type metal expansion joint, both ends are welded to connect by chock and side wall；First
It is welded to connect between arc, the first arc and the second arc overlap joint connect, and the second arc passes through chock and both sides water
Cold wall is welded to connect；Mounting hole is opened on combination angle steel, the structure setting more than, steel plate expanded by heating, and can be met
Ensure sealing well, the utility model structure utilizes flow of flue gas and flying dust characteristic, subtracted by increasing flue gas guider
Small flue gas resistance, flue gas flow rate is improved, reducing flue-gas temperature reduces amplitude, and the flue gas of upper flow regime makes flying dust be easier to be carried over pot
Furnace body exports；
Using the boiler of the utility model fluid structure so that easily dust stratification eliminates at the furnace outlet of dust stratification originally, and
And flue gas becomes easier to flow.By checking, its flue structure can substantially increase the flow velocity into back-end ductwork flue gas, reduce
Dust stratification before boiler body outlet, substantially increases boiler operating efficiency.
