Description

A kind of novel multi-functional waste-heat recovery device for dry slag-discharging boiler

Technical field

The utility model belongs to dry slag-discharging boiler heat recovery technology field, more particularly to a kind of novel multi-functional is used for The waste-heat recovery device of dry slag-discharging boiler.

Background technique

The thermal efficiency formula of coal-burning boiler are as follows: η 2=100- ∑ q=(q2+q3+q4+q5+q6), in which: η 2 is that boiler is anti- It balances the thermal efficiency (%)；Q2 is heat loss due to exhaust gas (%)；Q3 is gas incomplete combustion heat loss (%)；Q4 is that solid is incomplete Combustion heat loss (%)；Q5 is radiation loss (%)；Q6 is heat loss due to sensible heat in slag (%).The lime-ash of coal-burning boiler discharge also has Have higher temperature, entrained by physical sensible heat be known as heat loss due to sensible heat in slag q6.Influence heat loss due to sensible heat in slag's size Principal element is the size of bed drain purge and the height of ash temperature.

Be higher than 30% medium and low heat value fuel to ash content, if lime-ash without cooling, heat loss due to sensible heat in slag up to 2% with On.On the other hand, the processing and transport of red-hot lime-ash are cumbersome, are unfavorable for mechanized operation, and general lime-ash processing is mechanical The temperature upper limit that can be born is necessary at 150 DEG C hereinafter, therefore carrying out cooling to lime-ash mostly.

Currently, the dry slag-discharging boiler of large-size thermal power plant generallys use air-cooled dreg removing system.The air-cooled deslagging The working principle of system is as follows: the hot lime-ash of coal-burning boiler discharge falls on steel after transition slag bucket (or slag well), hydraulic shutoff door On the conveying steel belt of belt slag extractor, and moved together with the conveying steel belt slowly moved；The two sidewalls of dry bottom ash air-cooling conveyor and Head-tail is equipped with air inlet, and controlled a small amount of ambient, cool air is sucked under the action of combustion chamber draft；Containing imperfect combustion The lime-ash of combustible inversely contacted with the cold air of sucking in dropping process and on conveying steel belt to further firing It burns, and carries out heat exchange with the cold air, to be cooled to low temperature lime-ash；Cold air can be heated to 250 DEG C -400 DEG C Left and right, the temperature of hot lime-ash can drop to 200 DEG C hereinafter, even lower than 100 DEG C, while sucking cold air by 600 DEG C -850 DEG C Also by the heat recovery of lime-ash and bring into furnace；Dry slag after cooling is after level-one or two-stage are broken, by mechanical or pneumatic conveying System is delivered to slag storage and deposits.

Dry-type slag extractor utilizes boiler lost pressure cooling warm sludge by natural wind, while by heat with back boiler.Dried slag removing Heat of the machine with back boiler mainly includes the thermal loss q4 of unburned coal in bottom ash, bottom ash physics heat loss q6 and slag-drip opening The three parts such as radiation heat loss q5.Lime-ash is cooled down using cool ambient air, cooling air quantity is up to the 1.3% of specified total blast volume Left and right, otherwise can adversely affect the safe and stable operation of boiler.

From the aspect of burning, the cooling air quantity and cooling wind of dry bottom ash air-cooling conveyor are additionally depended on to the influence of boiler thermal efficiency Charging temperature.When one timing of lime-ash cooling wind caloric receptivity, cooling air quantity is bigger, and wind-warm syndrome is lower.When cooling wind temperature is close to two When the hot blast temperature of secondary air-supply, cooling wind is sent into as air needed for burning from furnace bottom, is protected entering furnace total combustion air amount Hold it is constant in the case where, from furnace bottom be sent into excess air can make accordingly to reduce by the cold air amount of air preheater, thus Cause the exhaust gas temperature of boiler to increase, and then reduces the thermal efficiency of boiler.

In order to guarantee Combustion Operation of Boilers and boiler efficiency, enter boiler furnace after the cooling warm sludge of dry bottom ash air-cooling conveyor Air quantity be usually no more than boiler and always burn the 1.3% of air quantity, the wind-warm syndrome into burner hearth is not less than 250 DEG C -400 DEG C；It considers The heatproof of the harm of operations staff, ambient enviroment and influence and lime-ash subsequent delivery equipment design etc. is required, slag extractor or The deslagging temperature of slag cooler is usually no more than 200 DEG C.For the boiler of certain capacity, do not changing boiler combustion air distribution Under the premise of, allow by the air quantity that boiler bottom enters burner hearth to be certain.However, in actual operation, the coal of coal fired thermal power plant Source coal quality is more miscellaneous, changes greatly, and the coal quality actually used often deviates design and checks coal quality, boiler slag removal amount, ash discharge quantitative change Change very big (these depend primarily on the situation of change of coal supply and coal market), the variation for thereby resulting in boiler slag removal amount is It is passively and (being difficult to be quantitatively evaluated in the design selection stage) not easy to control, lead to cooling air quantity and the cooling of dry bottom ash air-cooling conveyor Wind-warm syndrome and processing capacity also change therewith, these all can stability to Combustion Operation of Boilers and the thermal efficiency generate negative shadow It rings, to influence the security reliability and economy of unit operation.For example, when the coal quality of boiler combustion is deteriorated, the row of boiler The quantity of slag will be greater than the bed drain purge initially checked, and increase so as to cause the air quantity for being sent into burner hearth by air-cooled dry-type slag discharging machine.Such as It is upper described, in the case where entering furnace total combustion air amount and remaining unchanged, this meeting so that by air preheater cold air amount phase It should reduce, be increased so as to cause the exhaust gas temperature of boiler, and then reduce the thermal efficiency of boiler.
