Its technical scheme is, a kind of high ash low temperature exhaust heat boiler, and which includes horizontal flue and drum, the horizontal flue
Including by connecting vaporizer casing, economizer and the preheater that flue is linked in sequence successively, it is characterised in that：The vaporizer
Heating surface in casing is in longitudinally staggered disposition, is provided with installing hole on the vaporizer casing, and soot blower is arranged at the installing hole
It is interior.
Further, the economizer and preheater are arranged in same casing.
Further, the vaporizer casing is provided with four groups, is connected by connecting flue between two adjacent groups vaporizer casing
Connect, between each group of vaporizer casing and connection flue, be provided with expansion joint.
Further, the bottom water inlet pipe of the economizer is connected with circulation pump conduit, the top water outlet of the economizer
Pipe is connected with the drum, and the drum is connected with each vaporizer casing by down-comer, and each vaporizer casing passes through
The soda pop fairlead of mouth header is connected with the drum, is provided with water separator in the drum.
Further, the preheater connects inlet pipeline, outlet pipeline respectively, and the external hot water of the outlet pipeline sets
It is standby.
The beneficial effects of the utility model are：Its pass through by the heating surface in vaporizer be set to be staggered in arrangement so as to
Effect reduces dust stratification and enhances heat-transfer effect；And soot blower is arranged by installing hole on vaporizer casing, can be reliable in time
Dust stratification in ground clean expander, so that increased the safety and reliability of boiler.
