Description
Technical field
The present invention relates to a kind of boiler of organic heat carrier, specifically a kind of vertical bottom of connection in series-parallel mixing combusts oily combustion
Gas boiler of organic heat carrier belongs to boiler plant technical field.
Background technology
Currently, the heating surface that the vertical bottom of LS types combusts oily gas organic heat carrier boiler is by two layers of disk pipe or three layers of circle
Coil pipe is nested together composition, in innermost coil pipe inner ring coil pipe, intermediate coil pipe centre circle coil pipe, the coil pipe in outside
Outer ring coil pipe, every layer of coil pipe are made of the spiral coil of one or more coil pipe parallel connection, walk organic heat carrier inside coil pipe, and two
Flue gas is walked in gap between layer coil pipe, and boiler heat absorption is divided into radiant heat and advection heat, and radiations heat energy accounts for 60%, and convection heat accounts for
40%, inner ring coil pipe absorbs whole radiations heat energies and a part of advection heat, 70% about always to recept the caloric, and centre circle and outer ring absorb
Remaining advection heat.
Inside and outside coil pipe has two ways in parallel or series under normal circumstances, when using parallel connection, organic heat carrier by into
Mouth header enters inside and outside three and encloses coil pipe simultaneously, is then mixed in outlet header, the medium flow field that such structure passes through every pipe
Amount is determined by the length of single cell, and since the caloric receptivity of every circle coil pipe is different, general is difficult in allowing every pipe
Caloric receptivity is consistent, results in the Coil outlet temperature in every circle inconsistent in this way, and it is easy to appear lists if arrangement is unreasonable
Root pipe overtemperature, to damage boiler.When using series connection, organic heat carrier enters outer ring coil pipe by import header, by outer ring
Coil pipe enters centre circle coil pipe, then enters inner ring coil pipe by centre circle coil pipe, finally enters outlet header, is arranged so every pipe
Caloric receptivity is uniform, but since the length of single cell is that three circle coil pipes are added, the medium resistance of boiler under normal circumstances
Power is bigger.The very big portion's wind consumption of the power consumption of circulating pump is uneconomical on boiler body.In addition the medium in such boiler is walked
One N word shape, can not be by the mediator depletion in stove in repair and maintenance boiler.Sometimes due to the characteristic by medium is influenced blowing out
Otherwise mediator depletion can be solidified after medium cooling, can not be used after causing by Shi Bixu.In addition the second of this two kinds of structures
Flue gas and medium in convection section are downstream heat transfers, and heat transfer effect is poor, influence the thermal efficiency of boiler.
Invention content
It is an object of the present invention to overcome the above deficiencies, and the vertical bottom to provide a kind of connection in series-parallel mixing combusts oil
Gas organic heat carrier boiler, by the way that outer ring and centre circle coil pipe is in parallel, it is intermediate by an intermediate mixing header again with inner ring
Series connection, solves the problems, such as parallel-connection structure boiler export coil temperature deviation, makes to enter the temperature that outlet header obtains every coil pipe
Equally, by adjusting flue gas trend and medium flow direction, the flue gas of the second convection section is made to become countercurrent flow with medium, improves boiler
The thermal efficiency is obtained, while it is big with resistance to solve the problems, such as that cascaded structure can not be emptied.
According to technical solution provided by the invention, a kind of vertical bottom of connection in series-parallel mixing combusts oily gas organic heat carrier pot
Stove includes boiler barrel, and burner hearth is equipped in boiler barrel, it is characterized in that：Inside burner hearth from inside to outside successively be equipped with inner ring coil pipe,
Centre circle coil pipe and outer ring coil pipe, centre circle coil pipe and outer ring coil pipe are arranged in parallel, and the input end of centre circle coil pipe and outer ring coil pipe is upward
It stretches out boiler barrel and connects import header jointly, the outlet end of centre circle coil pipe and outer ring coil pipe extends downwardly boiler barrel and is total to
With the intermediate mixing header of connection；Inner ring coil pipe is arranged in series with centre circle coil pipe, outer ring coil pipe, and inner ring coil pipe input end extends downwardly
Boiler barrel simultaneously connects intermediate mixing header, and boiler barrel and connection outlet header are stretched out in inner ring coil outlets end upwards；Inner ring
The first convection current exhaust gases passes, outer ring coil pipe and boiler barrel are formed between coil pipe and centre circle coil pipe, centre circle coil pipe and outer ring coil pipe
The second convection current exhaust gases passes are formed between side wall.
Further, intermediate mixing header is equipped with mediator depletion mouth.
Further, boiler barrel bottom centre is equipped with burner, and the burning spout of burner stretches into burner hearth.
Compared with the prior art the present invention has the following advantages：
The invention has the advantages of simple structure, compactness and reasonable structure, and the medium due to entering inner ring coil pipe mixes in advance in intermediate mixing header,
Keep the medium temperature into inner ring coil pipe consistent, to make Coil outlet temperature be consistent, ensure that the safe operation of boiler；
Two the first convection current exhaust gases passes are in parallel downwards, reduce a flue gas backhaul, reduce boiler smoke collateral resistance, reduce drum
The power consumption of wind turbine；Meanwhile second convection current exhaust gases passes flue gas and media for heat exchange become countercurrent flow, improve the thermal effect of boiler
Rate；Third, medium can be drained by the evacuation port of intermediate mixing header in Boiler Furnace, be provided conveniently for blowing out and maintenance；The
Four, the resistance of boiler body is reduced, circulating pump effective power consumption is improved.
