Abstract

The invention relates to a dual radiation heat exchange coil component for a boiler furnace, comprising a single-cavity coil group formed by integral, close and spiral winding and a double-cavity coil group. The single-cavity coil group is formed by parallel close spiral winding of a plurality of coils for at least one cycle; and the double-cavity coil group is formed by dividing the plurality of the coils into two parts which are closely and spirally wound in parallel for at least two cycles respectively. The dual radiation heat exchange coil component for the boiler furnace adopts the novel and unique double-cavity coil group, the space is utilized reasonably and the radiation and heat exchange area is enlarged under the condition of fixed volume of the furnace, so that the heat exchange function of the radiation section is fully enhanced, and the entire heat efficiency of a heat conduction oil boiler is greatly improved; although the radiation and heat exchange area is increased, the volume of the furnace is unnecessarily enlarged, the area occupied by a boiler room is reduced, material is saved, and the weight of a boiler body is reduced; and the dual radiation heat exchange coil component for the boiler furnace can further fit for the development of organic heat transfer material heaters to large volumes.

Description

The biradial heat exchange coil assembly that is used for boiler furnace
Technical field
The present invention relates to a kind of biradial heat exchange coil assembly that is used for boiler furnace.
Background technology
Existing boiler furnace all is provided with the radiation heat transfer assembly in the radiation of burner hearth heat affected zone, and present radiation heat transfer assembly is mainly the burner hearth single closed circuit of square coil pipe all around, and this closed circuit closely is entwined (as shown in Figure 1) side by side by some pipes.
Along with the fast development of technology, boiler is done bigger and bigger, and heat-exchanging component also needs to strengthen the radiation heat transfer area.Radiation assembly heat exchange closed circuit among Fig. 1 is simple, and heat exchange area is limited, influences the thermal efficiency of boiler.
Summary of the invention
The technical problem to be solved in the present invention is: in the certain boiler furnace of volume, the Enhanced Radiation Reduced Blast heat exchange area improves the thermal efficiency, the invention provides a kind of biradial heat exchange coil assembly that is used for boiler furnace.
The technical solution adopted for the present invention to solve the technical problems is: a kind of biradial heat exchange coil assembly that is used for boiler furnace, comprise single chamber coil pipe group and two-chamber coil pipe group that the tight spiral of one is entwined, described single chamber coil pipe group is twined at least one circle by the tight side by side spiral of many coil pipes and is formed, two-chamber coil pipe group is divided into two parts by described many coil pipes, and every part of tight side by side respectively spiral twines at least two circles and forms.
Concrete, the radical of described many coil pipes is 4~16.
Further, the setting of the number of turns is by calculating, the factor of required consideration has: heat-conducting medium circular flow, boiler tube specification, boiler caloric value (boiler output) etc., in order to guarantee that the radiant section velocity of medium reaches zone of reasonableness 〉=2m/s in the boiler tube, the excessive then resistance of flow velocity increases, described single chamber coil pipe group is twined 1~3 circle by the tight side by side spiral of many coil pipes and is formed, and two-chamber coil pipe group is divided into two parts by described many coil pipes, and every part of tight side by side respectively spiral winding 2~6 is enclosed and formed.
The invention has the beneficial effects as follows, the present invention adopts novel unique two-chamber coil pipe group, under the certain situation of combustion space, rationally utilize the space, the Enhanced Radiation Reduced Blast heat exchange area is fully strengthened the heat exchange function of radiant section, improves the overall thermal efficient of heat-conducting oil furnace greatly, solve the coil pipe bottom and directly be subjected to fire to cause the overheated coking of organic heat carrier easily, and the problem that causes a serious accident.Though increased the radiation heat transfer area, need not increase combustion space, reduced the floor space of boiler room, save material, alleviate body of heater weight, can also adapt to organic heat carrier furnace and develop to bigger capacity.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the heat-exchanging component vertical view in the existing boiler furnace.
Fig. 2 is the vertical view that the present invention is used for the optimum embodiment of biradial heat exchange coil assembly of boiler furnace.
Fig. 3 is that the A of Fig. 2 is to view.
Among the figure 1, single chamber coil pipe group, 2, two-chamber coil pipe group.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
The present invention of being shown in Figure 3 is used for the optimum embodiment of biradial heat exchange coil assembly of boiler furnace as Fig. 2, a kind of biradial heat exchange coil assembly that is used for boiler furnace, comprise single chamber coil pipe group 1 and two-chamber coil pipe group 2 that the tight spiral of one is entwined, single chamber coil pipe group 1 is formed by square winding 3 circles of the tight side by side spiral of 6 coil pipes, 6 coil pipes after two-chamber coil pipe group 2 is enclosed by winding 3 are divided into two parts, and every part of then tight side by side spiral winding 3 is enclosed and formed.
Overheated coking is the burner hearth skewness that is heated, and local temperature is too high to cause conduction oil (medium) Pintsch process and coking, and the biradial segment structure is equal to sets up heating surface in the burner hearth, strengthens the heat exchange effect and reduces the influence of overheated coking to burner hearth to a certain extent.
The scope of application: fuel is II, III class bituminous coal, the medium-and-large-sized square chest stove of chain or reciprocal grate.When fuel is fuel combination, scoot, sanding powder etc.,, easily cause boiler tube to stop up, so want enough greatly in the space that the combustion chamber needs because that the ash that burning is produced flies particle is bigger.The biradial heat exchange coil assembly that the present invention is used for boiler furnace is not suitable for using in medium-sized square chest stove design, and effect is more obvious in large-scale or the super large type of furnace, and suggestion is promoted the use of.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
