Description
Technical field
This utility model relates to power plant coal-burning boiler equipment technical field, particularly relates to a kind of for power plant fire coal pot
The sliding bottom of the low low-level (stack-gas) economizer of stove.
Background technology
The coal-burning boiler heat loss due to exhaust gas that is in operation in power plant is a very prominent heat loss, accounts for the heat that boiler is total
Loss 60-70%, runs exhaust gas temperature in the thermal power plant that China is most and is usually above design load.Damage to reduce smoke evacuation
Lose, reduce exhaust gas temperature, improve the pick up the heat efficiency in power plant, the most usually use the low low-level (stack-gas) economizer height to discharge
Temperature flue gas carries out waste heat recovery recycling.Low low-level (stack-gas) economizer is as on big-and-middle-sized boiler of power plant air preheater exhaust pass
Heat transmission equipment, being mainly manifested in of it: (1) reduces exhaust gas temperature, improve boiler efficiency, save fuel；(2) recovered flue gas
Heat, heat-setting water；(3) optimize flue-gas temperature, improve efficiency of dust collection；(4) desulfurization water spray is reduced；(5) blower fan electric current is reduced.
Current low low-level (stack-gas) economizer uses suspention and supports two kinds of fixed forms, and in configuration aspects, low low-level (stack-gas) economizer is by high temperature section
Form with low low-temperature zone, the fixed form using conventional and low low-level (stack-gas) economizer identical be accomplished by high temperature section and low low-temperature zone it
Between install and can absorb the device of swell increment, but between low low-level (stack-gas) economizer height low-temperature zone, flue locational space is limited, inconvenience
In installing the device absorbing swell increment.Therefore, for this defect, research one can save coal to low temperature in the confined space
The device that device is fixed has great importance.
Utility model content
The drawbacks described above existed for low low-level (stack-gas) economizer fixed installation structure in prior art, the purpose of this utility model
Being: provide a kind of sliding bottom for the low low-level (stack-gas) economizer of power plant coal-burning boiler, it has simple in construction, design is closed
Reason, reliable and stable, production and maintenance cost are low and can effectively solve the problem that low low-level (stack-gas) economizer high temperature section expands with low low-temperature zone
The advantages such as amount.
In order to achieve the above object, this utility model adopts the following technical scheme that
A kind of sliding bottom for the low low-level (stack-gas) economizer of power plant coal-burning boiler, this sliding bottom is arranged on low temperature and saves
Bottom coal device and between low low-level (stack-gas) economizer support beam, described sliding bottom includes that limited block, low low-level (stack-gas) economizer supporting leg are solid
Determine plate, expansion oplate, sliding bottom fixed plate；Wherein, low low-level (stack-gas) economizer supporting leg fixed plate is connected with low low-level (stack-gas) economizer supporting leg,
And by expansion oplate and sliding bottom fixed plate slidable connection, sliding bottom fixed plate is with low low-level (stack-gas) economizer support beam even
Connecing, limited block is fixedly installed in sliding bottom fixed plate.
As the further optimization of technique scheme, described one is used for the low low-level (stack-gas) economizer of power plant coal-burning boiler
Sliding bottom, described sliding bottom limited block is L-type structure, and described limited block is welded in sliding bottom fixed plate.
As the further optimization of technique scheme, described low low-level (stack-gas) economizer supporting leg fixed plate uses heavy wall plate,
It is welded to connect with low low-level (stack-gas) economizer supporting leg.
Compared with low-level (stack-gas) economizer low with prior art fixed installation structure, use this utility model one for power plant
The sliding bottom of the low low-level (stack-gas) economizer of coal-burning boiler has the advantages that
(1) outside sliding bottom is arranged on low low-level (stack-gas) economizer not with smoke contacts, flue-gas temperature, cigarette need not be considered during design
The gas corrosion impact on material therefor；
(2) simple in construction, design is more reasonable, and it is few that single unit system produces materials, easy for installation；
(3) reduce the workload that site operation is installed, improve installation effectiveness, reduce cost of investment.
Accompanying drawing explanation
Accompanying drawing 1 is the simple knot of a kind of sliding bottom for the low low-level (stack-gas) economizer of power plant coal-burning boiler of this utility model
Structure schematic diagram.
Detailed description of the invention
1 pair of a kind of sliding bottom for the low low-level (stack-gas) economizer of power plant coal-burning boiler of this utility model below in conjunction with the accompanying drawings
Structure and working principle be described in detail.
A kind of sliding bottom for the low low-level (stack-gas) economizer of power plant coal-burning boiler, this sliding bottom is arranged on low temperature and saves
Bottom coal device and between low low-level (stack-gas) economizer support beam 1, described sliding bottom includes limited block 2, low low-level (stack-gas) economizer supporting leg
Fixed plate 3, expansion oplate 4, sliding bottom fixed plate 5；Wherein, low low-level (stack-gas) economizer supporting leg fixed plate and low low-level (stack-gas) economizer supporting leg
6 connect, and by expansion oplate and sliding bottom fixed plate slidable connection, sliding bottom fixed plate is propped up with low low-level (stack-gas) economizer
Support beam connects, and limited block is fixedly installed in sliding bottom fixed plate.Sliding bottom limited block is L-type structure, and limited block welds
In sliding bottom fixed plate.Low low-level (stack-gas) economizer supporting leg fixed plate uses heavy wall plate, welds with low low-level (stack-gas) economizer supporting leg even
Connect.
The above-mentioned operation principle for the sliding bottom of the low low-level (stack-gas) economizer of power plant coal-burning boiler of this utility model is: low
The low low-temperature zone of low-level (stack-gas) economizer and high temperature section can connect into an entirety, and sliding bottom is arranged on low low-level (stack-gas) economizer and low
