Abstract
A kind of coal-burning boiler based on smoke evacuation vapor internal-circulation type condensing units, belong to boiler heat supplying and technical field of energy utilization, for heating coal-burning boiler, using the wet loop jump module recovery smoke discharging residual heat of three heat, exhaust gas temperature is reduced to convergence atmospheric temperature by spray mode by condensation intermediary's recirculated water and realizes that " disappearing white " discharges afterwards by low-temperature zone cooling and dehumidification module of wherein discharging fume, and absorbs smoke discharging residual heat and condensate；Inlet air of boiler warming and humidifying module directly sprays warming and humidifying by condensing intermediary's recirculated water to inlet air of boiler, and high humidity air intake is sent into burner hearth after air preheater, is transferred to so as to which smoke evacuation condensate is undergone into burner hearth combustion process with vapor form again in boiler exhaust gas；The boiler exhaust gas of water capacity is significantly improved then by high temperature section waste heat recovery module of discharging fume by the recovery waste heats such as heat supply network backwater and condensate；Flue gas then goes successively to next stage heat exchanger.Above-mentioned exhaust heat recovery mode can bring up to the coal-burning boiler thermal efficiency close to 100%.
Description
Technical field
The coal-burning boiler based on smoke evacuation vapor internal-circulation type condensing units is the utility model is related to, belongs to boiler heat supplying
And technical field of energy utilization.
Background technology
Contain substantial amounts of vapor in being discharged fume using coal-burning boiler, thus the exhaust gas temperature of conventional boiler be generally up to 110~
160 DEG C or so, a large amount of latent heat and sensible heat in flue gas scatter and disappear in vain.Coal-burning boiler with fuel low heat valve calculate
Boiler thermal output by a variety of heat loss factors due to being influenceed without being likely to be breached 100%, according to boiler heat balance relation, combustion
The heat loss of coal burning boiler mainly includes：Heat loss due to exhaust gas Q2；Gas (chemistry) heat loss due to incomplete combustion Q3；Solid (machinery) is no
Completely burned heat loss Q4；The lost Q5 of boiler radiating；Other heat loss Q6.Typically the thermal efficiency of small scall coal-fired boiler only has
50%~60% is even lower, but the thermal efficiency of large-scale heating coal-burning boiler because of combustion process more fully, all kinds of reductions taken
The technical measures of heat loss are more perfect etc., and generally up to 82%~91% or so, wherein Q3, Q4, Q5, Q6 etc. passes through in technology
The degree of the limit has been optimized in feasible scope of helping.But for coal-burning boiler, it is maximum effectively to reduce heat loss technical difficulty
Be heat loss due to exhaust gas Q2, its main cause is both to be to discharge fume both to scatter and disappear containing certain sensible heat, more contain a large amount of vapor
And its amount of latent heat, although the latter is not counted in the calculating category of fuel low heat valve, its fume afterheat total amount is generally very big, can
7%~9% or so into stove fuel thermal discharge is reached, and is limited to larger amount of sulfide contained in smoke evacuation, nitrogen oxides etc.
Corrosive gas composition, coal-burning boiler exhaust gas temperature are normally controlled in water dew point, more than sulphur dew point, i.e., usually more than 100 DEG C, then
Substantial amounts of sensible heat particularly vapor latent heat in smoke evacuation is forced to scatter and disappear in vain, also therefore how to realize and safely and effectively reclaims
Heat loss due to exhaust gas Q2, design novel coal-fired boiler is become to greatly improve the key point of boiler overall thermal efficiency.
China is just carrying out discharging fume the standard of minimum discharge on a large scale in boiler heat supplying field at present, then boiler exhaust gas removes
Dirt, desulphurization and denitration index will progressively level off to 5mg/Nm3、35mg/Nm3、50mg/Nm3Or even lower discharge standard, this be into
The smoke evacuation depth waste heat recovery of row boiler particularly coal-burning boiler, greatly improve boiler overall thermal efficiency and provide superior technique bar
Part and economic feasibility.
To reclaim fire coal boiler fume waste heat, the mode and its feature of currently used waste heat recovery are as follows.
(1) direct-type Exposure degree：The most conventional mode, fume afterheat is used for preboiler air intake, boiler returns

Left and right, but flue gas is only heated to air and not humidified, and smog discharge temperature is high, and water capacity is big, and waste heat recovery volume is limited.
(2) condenser boiler heat reclamation device：Exhaust gas temperature can be reduced to about 50 DEG C, and fume afterheat is used for preboiler
Air intake, boiler blow-down water or heat supply backwater etc., flue gas are in condensing heat-exchange area, and coal-burning boiler efficiency is improved up to 2%~5%
Left and right, total boiler efficiency reach as high as 93~97% or so, the efficiency of system influenceed by heat supply backwater it is big, such as backwater
Temperature, which improves, then necessarily causes exhaust gas temperature to improve, and cigarette temperature is further reduced and had any problem.
(3) the flue gas condensing heat reclamation device based on absorption heat pump heat exchange：The efficiency high of absorption type heat pump system, row
Cigarette temperature can be reduced to 20~30 DEG C, and flue gas is in deep condensation heat transfer zone, and coal-burning boiler efficiency is improved up to 7%~9%
Left and right, total boiler efficiency reach as high as 97~101% or so, and the efficiency of system is not influenceed by heat supply backwater substantially.But
The structure of absorption heat pump is more complicated, and cost is higher, and operation expense is larger, it is therefore desirable to considers its Technological Economy
Property, its economy is relatively poor for coal-burning boiler particularly relatively low to fuel price.
Therefore, the shortcomings that above-mentioned all kinds of boiler exhaust gas UTILIZATION OF VESIDUAL HEAT IN modes have respective advantage and disadvantage, and particularly its is intrinsic
On the problems such as being reflected in technology exploitativeness, cost performance, its extensive use is often limited.
In addition, boiler exhaust gas is because containing a large amount of vapor, even minimum discharge standard is had been realized in, but its chimney goes out
Often be present " white cigarette " phenomenon in mouth, particularly in the winter time, because a large amount of steam and cold air largely condense into rapidly water, show as more
Significantly " white cigarette " phenomenon, there is the phenomenon that the periphery masses raise an objection to such pollution in many places, therefore it is required that boiler smoke
Chimney " disappearing white " has become the environmental protection policy requirement in many cities.
