Description
Technical field
The utility model relates to a kind of boiler of organic heat carrier, specifically a kind of vertical bottom mixed in series and parallel is combusted
Oily gas organic heat carrier boiler belongs to boiler plant technical field.
Background technique
Currently, the heating surface that the vertical bottom of LS type 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 energy 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 circles coil pipe simultaneously, then mixes in outlet header, the medium flow field that such structure passes through every root canal
Amount is determined by the length of single cell, since the caloric receptivity of every circle coil pipe is different, is generally difficult to allow in every root canal
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
The sub- overtemperature of root canal, 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 root canal
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 furnace 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, be not available 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.
Summary of the invention
In place of the purpose of this utility model is to overcome above-mentioned deficiency, to provide a kind of vertical bottom burning mixed in series and parallel
Fuel-firing gas-firing boiler of organic heat carrier, by the way that outer ring and centre circle coil pipe is in parallel, centre 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 obtain every coil pipe into outlet header
Temperature is the same, by adjusting flue gas trend and medium flow direction, the flue gas of the second convection section and medium is made to become counterflow heat exchange, improved
Boiler obtains the thermal efficiency, 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 utility model, a kind of organic heat load of vertical bottom burning fuel-firing gas-firing mixed in series and parallel
Body boiler includes boiler barrel, burner hearth is equipped in boiler barrel, it is characterized in that: being successively arranged inner ring disk inside burner hearth from inside to outside
Pipe, centre circle coil pipe and outer ring coil pipe, centre circle coil pipe and outer ring coil pipe are arranged in parallel, the input end of centre circle coil pipe and outer ring coil pipe to
Upper stretching boiler barrel simultaneously connects import header jointly, and the outlet end of centre circle coil pipe and outer ring coil pipe extends downwardly boiler barrel simultaneously
It is common to connect intermediate mixing header；Inner ring coil pipe is arranged in series with centre circle coil pipe, outer ring coil pipe, and inner ring coil pipe input end is stretched downwards
Boiler barrel and intermediate mixing header is connected out, boiler barrel and connection outlet header are stretched out in inner ring coil outlets end upwards；It is interior
The first convection current exhaust gases passes, outer ring coil pipe and boiler drum are formed between circle 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 body sidewall.
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 protrudes into burner hearth.
Compared with the prior art the utility model has the advantage that
The utility model structure is simple, compact, reasonable, and the medium due to entering inner ring coil pipe mentions in intermediate mixing header
Preceding mixing keeps the medium temperature into inner ring coil pipe consistent, so that Coil outlet temperature be made to be consistent, ensure that the peace of boiler
Row for the national games；Two the first convection current exhaust gases passes are in parallel to be reduced a flue gas backhaul, reduces boiler smoke collateral resistance downwards,
Reduce the power consumption of air blower；Meanwhile second convection current exhaust gases passes flue gas and media for heat exchange become counterflow heat exchange, improve boiler
The thermal efficiency；Third, medium can be drained by the evacuation port of intermediate mixing header in Boiler Furnace, be blowing out and maintenance provider
Just；4th, the resistance of boiler body is reduced, circulating pump effective power consumption is improved.
