Abstract
The invention relates to a boiler coal economizer and belongs to the technical field of boiler corollary equipment. The boiler coal economizer comprises guard plates, supporting beams, pipe clamps and a coiled pipe system. A flue is formed by the guard plates in an enclosed mode, and the coiled pipe system is mounted in the flue. The supporting beams are horizontally erected on the guard plates. The pipe clamps are vertically fixed to the supporting beams. The coiled pipe system comprises a set of coiled pipe bundles which are disposed at the same height and are arranged at intervals. The coiled pipe bundles are fixed by the pipe clamps. The coiled pipe system is provided with locating plates. The locating plates are arranged adjacent to the pipe clamps. Connecting round steel penetrates through the locating plates. The coal economizer is simple in structure and convenient to mount and repair; not only is the rigidity of the whole pipe system guaranteed, but also free expansion of the coiled pipe system is ensured; besides, heat transfer is not affected, and the problem that the pipe bundles of the coal economizer are too high and consequently instability and deformation are caused easily is solved.
Description
Technical field
The invention belongs to boiler matching equipment technical field, and in particular to for a kind of boiler economizer.
Background technology
Economizer is arranged in boiler back end ductwork using the heat of boiler tail low-temperature flue gas come heating boiler feed water.Water
Flow from lower to upper in economizer, flue gas washes away from top to bottom snakelike piping, convection heat transfer' heat-transfer by convection is formed, by the heat transfer of flue gas
To the water in snakelike piping.Because it absorbs the heat of low-temperature flue gas, the exhaust gas temperature of flue gas is reduced, saves the energy,
Efficiency is improve, so referred to as economizer.
Mode of hanging is propped up typically using supporting type by economizer coiled pipe system, and snakelike piping is bearing in backbar by pipe clamp
On, but this kind of pattern requires that pipe clamp has stronger rigidity, in order to avoid stability is lost after pressurized.Therefore per the tube bank of one-level economizer
Height can not be too high, and otherwise not easy enough the unstability of pipe clamp rigidity is so as to causing tube bundle deformation.When excessive height is restrained, can only be by one
Level economizer splits into two-stage, and between two-stage tube bank corresponding space for maintenance must also be left, and thus considerably increases the total of economizer
Body height so that boiler arranges that enough economizers are more difficult in limited space.For the problems referred to above, exploitation one is needed badly
Simple structure is planted, it is easy to installation and maintenance, a kind of boiler economizer of pipe clamp rigidity can be effectively improved.
The content of the invention
It is an object of the invention to overcome defect and deficiency mentioned above, and provide a kind of boiler economizer.

The snakelike tube bank equidistantly arrangement, it is described to position the equidistant straight line arrangement of plate level.
The left and right sides of coil system upper and lower ends is equipped with location-plate；The corner of the snakelike piping is provided with
Location-plate.
Locating sleeve is provided between adjacent positioned plate；The locating sleeve and location-plate wear connection round steel；Connection
Round steel is connected locating sleeve and location-plate.
The shorter locating sleeve of connection round steel two ends welding equipment.
A kind of boiler economizer, also including header, the header is fixed on bearing by U bolt；The bearing is arranged
On backplate；The mounting hole for being available for U bolt to pass through is offered on the bearing；Two ends are worn after the U bolt banding header
Cross mounting hole and fixed by nut.
Heat-insulation layer is filled with the backplate.The heat-insulation layer is made up of insulation material.
Beneficial effects of the present invention are as follows：
1. connect by the location-plate that welds in the snakelike tube bank top and the bottom position per piece and with connection round steel correspondence, then with fixed
Position sleeve pipe ensures pitch between pipe, makes whole snakelike piping define stable frame structure, so as to substantially increase pipe clamp rigidity.
The load concentration of so snakelike piping is passed on pipe clamp in vertical direction, piping gravity, and pipe clamp need to only support gravity, not by level
The effect of power, so as to avoid during economizer tube bank excessive height due to tube bundle deformation caused by the inadequate unstability of pipe clamp rigidity.
2. this device take into account the factor that part expands with heat and contract with cold：Location-plate is adjacent with pipe clamp and does not weld, and both ensure that
The gravity of snakelike piping is passed to immediately on pipe clamp, also ensures that snakelike piping energy free wxpansion；Economizer header is solid by U bolt
It is scheduled on bearing, and bolt hole is mounting hole, it is ensured that the free expanding of header.
3. in this kind of economizer, the cross-sectional area for connecting round steel and locating sleeve is less, several to flow of flue gas and dust stratification
Without impact.
4. boiler is solved using the boiler economizer of above structure and enough economizers are arranged in limited space
A difficult problem.Filling insulation material, as flue, eliminates thick and heavy flue furnace wall in backplate.
5. this kind of coal economizer structure is simple, and I＆M is more convenient.
