Detailed description of the invention
Below in conjunction with accompanying drawing, utility model is further described.
As shown in Figure 1, constant volume type Filter Tuber For Clean Coal burner, mainly include stove inwall 1, fire bars 2 and spring 3.Spring 3 is vertically arranged, spring 3 top and fire bars 2 bottom surface are welded to connect and support fire bars 2 so that fire bars 2 keeps level, spring 3 bottom and stove inwall 1 plate top surface to be welded to connect.Stove inwall 1 base plate, fire bars 2 and spring 3 material are solderable metal material.
Stove inwall 1 sidewall is upright side walls.Stove inwall 1 sidewall can be vertical cylinder, vertical square tube or other vertical irregular cylinder, and stove inwall 1 horizontal section area is constant.
Fire bars 2 is monoblock type short column body, and fire bars 2 bottom surface and end face are all arranged horizontally, and fire bars 2 sidewall is vertically arrange, fire bars 2 Sidewall Height and fire bars 2 thickness are δ.Setting gas channel in fire bars 2, the import of gas channel is in fire bars 2 bottom surface, and outlet is at fire bars 2 end face.It is coal-fired without falling into equal pressure chamber A that fire bars 2 blocks coal-fired layer B, and flows into coal-fired layer B offer gas channel for equal pressure chamber A air.
Spring 3 quantity can be one, it is possible to is many.When spring 3 quantity is one, the vertical central axis of fire bars 2 and spring 3 central axis conllinear.When spring 3 quantity is many, spring 3 is arranged symmetrically with, and steadily holds up fire bars 2 and coal-fired layer B, and spring force is to consistently equal to fire bars 2 gravity and coal-fired layer B gravity sum, and makes fire bars 2 end face and bottom surface be in level all the time.
Stove inwall 1 inner chamber is divided into equal pressure chamber A, coal-fired layer B and combustor C, combustor C to be the gas phase cavity of coal-fired layer B top face, and the fire coal that coal-fired layer B is fire bars 2 top face stacks region.It is upper and lower two parts that fire bars 2 separates stove inwall 1 cavity, and fire bars 2 lower cavity is equal pressure chamber A, and top cavity is bottom-up is followed successively by coal-fired layer B and combustor C.Equal pressure chamber A end face and fire bars 2 bottom surface overlap, and fire bars 2 end face and coal-fired layer B bottom surface overlap, and coal-fired layer B end face and combustor C bottom surface overlap.Fire bars 2 base area, horizontal sectional area and top surface area are equal, coal-fired layer B base area, and horizontal sectional area and top surface area are equal, and equal pressure chamber A sidewall, coal-fired layer B sidewall and stove inwall 1 sidewall are on same vertical barrel.
Between fire bars 2 end face outward flange with stove inwall 1 sidewall, between horizontal clearance with fire bars 2 bottom surface outward flange and stove inwall 1 sidewall, horizontal clearance is equal, and both of which is equal to horizontal clearance d between fire bars 2 sidewall and stove inwall 1 sidewall.The horizontal clearance d half less than fire bars 2 thickness δ between fire bars 2 sidewall and stove inwall 1 sidewall.On fire bars 2 end face or on coal-fired layer B end face during interpolation fire coal, under spring 3 elastic force effect, fire bars 2 jack-up fire coal layer B moves vertically downwards.When burning consumes coal-fired layer B fire coal, under spring 3 elastic force effect, fire bars 2 holds up coal-fired layer B and vertically moves up.No matter coal-fired layer B vertically moves up or moves down, and all makes coal-fired layer B top side location constant, and combustor C volume remains unchanged.Fire bars 2 thickness δ is more than the twice of fire bars 2 sidewall Yu stove inwall 1 sidewall horizontal distance d.Fire bars 2 is in stove inwall 1 cavity, and stove inwall 1 sidewall does not contact with fire bars 2 sidewall, and between fire bars 2 sidewall and stove inwall 1 sidewall, horizontal range is d, and meets 2d < δ, it is to avoid fire bars 2 is stuck in stove inwall 1 cavity when tilting, and strengthens stability when fire bars 2 moves.Coal-fired layer B fire coal particle diameter is not only greater than horizontal range d between fire bars 2 sidewall and stove inwall 1 sidewall, and more than fire bars 2 top air flow outlet diameter, it is possible to avoid coal-fired layer B fire coal to fall into equal pressure chamber A by horizontal clearance between fire bars 2 sidewall and stove inwall 1 sidewall and fire bars 2 gas channel.
Above fire bars 2, coal-fired layer B puts fire coal, and fire coal is piled up at coal-fired layer B under self gravitation effect.Equal pressure chamber A is the cloth wind space of fire bars 2 subjacent, and equal pressure chamber A sidewall offers air intlet.By equal pressure chamber A sidewall air import leaked-in air, flow through equal pressure chamber A sidewall air import, equal pressure chamber A, fire bars 2 and coal-fired layer B successively, finally enter coal-fired layer B end face combustion-supporting coal burning.Stove inwall 1 top is offered after the high-temperature flue gas that in the middle of exhaust opening, high-temperature flue gas and combustor C combustibility, gas firing is formed merges and is discharged from combustor C exhaust opening.
Practice have shown that: too little being unfavorable for of combustor C liberation maintains ignition temperature, be unfavorable for too greatly extending combustible at the high-temperature region time of staying and stroke, all can cause incomplete combustion.According to combustion law, combustor C liberation is stably maintained at 265kW/m3～305kW/m3Scope, is one of complete necessary and sufficient condition of burning.The Filter Tuber For Clean Coal burner of utility model indication catches fire from coal-fired layer B end face, and combustion front from up to down moves, and coal-fired layer B end face is combustion front, and between fire bars 2 area, fire bars 2 sidewall and stove inwall 1 sidewall, horizontal clearance is all invariable, and burning area is invariable.When air supply and stability of flow, combustion front can vertically from up to down steadily move, and keeps burning heat release rate constant.Fire bars arranges spring 32 times, support fire bars 2 with spring 3 and coal-fired layer B is coal-fired, fire bars 2 and coal-fired layer B gravity sum all the time and spring 3 elastic force equal, coal-fired layer B end face moves down distance and spring 3 and elongates apart from equal because elastic force reduces, reach coal-fired layer B end face be in initial position all the time and keep the effect of dynamic balance state, combustor C basal surface position is constant relative to stove inwall 1 so that combustor C volume is not changed in, and is finally reached combustor C liberation invariable.In accompanying drawing 1, coal-fired layer B Coal-fired capacity is many, coal-fired layer B height h is big, spring 3 stress pressure chamber A big, equal height H is little, in accompanying drawing 2, coal-fired layer B Coal-fired capacity is few, it is coal-fired that layer B height h is little, spring 3 stress is little, equal pressure chamber A height H is big, accompanying drawing 1 and accompanying drawing 2 equal pressure chamber A height H are equal all the time with coal-fired layer B height h sum so that coal-fired layer B top side location is constant relative to stove inwall 1.Now, the ratio of the combustor C volume that the burning heat release amount that coal-fired layer B top surface area determines determines with coal-fired layer B top side location is stably maintained at 265kW/m3～305kW/m3Zone of reasonableness.It addition, combustor C volume to easily cause furnace pressure when diminishing excessive, easy inspiration cold wind when combustor C volume becomes big and reduce ignition temperature, maintaining the combustor C constancy of volume is maintain combustion conditions and the constant important prerequisite of combustibility.
Coal-fired layer B height is h, and equal pressure chamber A is highly H, h and H sum can ensure that combustor C constant volume is constant when being definite value.Owing to spring 3 is vertically arranged, its top and bottom is welded to connect with fire bars 2 bottom surface and stove inwall 1 plate top surface respectively, and therefore all pressure chamber A is highly equal to spring 3 physical length.Spring 3 supports fire bars 2 and coal-fired layer B gravity and keeps dynamic equilibrium, and spring 3 elastic force is equal to fire bars 2 and coal-fired layer B gravity sum.
As shown in Figure 1, representing coal density with ρ, S represents coal-fired layer B horizontal sectional area, and G represents fire bars 2 gravity, and k represents spring 3 coefficient of elasticity, LoNatural length when representing spring 3 not by any External Force Acting.
Calculate by 1 spring 3.When special operation condition fire coal layer B coal all consumes, spring 3 is only limited by fire bars 2 gravity, and fire bars 2 top side location is the highest, and spring 3 length is Lcon, spring 3 stress balance is expressed as
k·(Lo–Lcon)=G (1)
When general operating mode fire coal layer B height shown in accompanying drawing 1 and accompanying drawing 2 is h, equal pressure chamber A is highly H, and coal-fired layer B top side location is fire bars 2 top side location when coal-fired layer B fire coal all consumes.Spring 3 is by fire bars 2 and coal-fired layer B action of gravity, and spring 3 stress balance is expressed as
k·(LoH)=G+ ρ S h (2)
The combustor C constancy of volume, namely
H+h=Lcon(3)
Simultaneous formula (1), formula (2) and formula (3) are it can be seen that spring 3 coefficient of elasticity adjusts
K=ρ S (4)
Coal-fired layer B height h and equal pressure chamber A height H sum is steady state value, it is ensured that combustor C constant volume, namely ensure that combustor C volume does not change with coal-fired layer B fire coal consumption.
Coal-fired layer B end face fire coal burns in layer combustion mode.Equal pressure chamber A air enters coal-fired layer B by fire bars 2 space, and carries out mixed combustion with being in coal-fired layer B end face fire coal.Carrying out with combustion reaction, coal-fired layer B weight reduces, and air flows through coal-fired layer B resistance and reduces.Coal-fired layer B weight minimizing makes spring 3 elastic force reduce and extend, and equal pressure chamber A volume increases, and causes that equal pressure chamber A static pressure reduces.Equal pressure chamber A volume increases and coal-fired layer B height reduction occurs simultaneously, equal pressure chamber A static pressure reduces and coal-fired layer B resistance reduction adapts, make to pass into the air mass flow of coal-fired layer B from equal pressure chamber A and flow velocity all remains stable for constant, it is to avoid all pressure chamber A volume becomes big and affects coal combustion energy-conserving and environment-protective performance.In tradition fixed grate formula coal furnace, coal-fired layer B height reduces, flow through coal-fired layer B resistance from air to reduce, equal pressure chamber A static pressure is constant, the air velocity flowing through coal-fired layer B becomes big, coal-fired layer B end face burning cooling effect is strengthened by air, and ignition temperature reduces, and causes that imperfect combustion probability strengthens.
Wall lining high-temperature refractory, stove inwall 1 can bear 1200 DEG C～1500 DEG C high temperature corrosion effects.Having coal-fired layer B to be separated by between combustor C combustion high temperature and all pressure chamber A, combustor C high temperature is not delivered to equal pressure chamber A, and equal pressure chamber A is in low temperature level all the time, it is prevented that the spring 3 being in equal pressure chamber A is subject to high temperature corrosion effect and shortens spring 3 service life.
The solid fuel that coal-fired layer B loads, ash mass percent is lower than 10%～12%, it is possible to be that low ash is coal-fired, it is possible to be low ash Filter Tuber For Clean Coal, it is possible to be low ash biomass material.
Utility model structure innovation, technical characteristic and the technique effect brought describe as follows:
