Abstract
The utility model provides a novel tubular square chest heating furnace in single face radiation tubular square chest heating furnace central authorities, installs fretwork heat radiation wall additional along the outside of combustor flame, with the central authorities of flame draw -around at the heat radiation wall, the heat radiation wall direct with flame and flue gas contact, flue gas contact or when passing the fretwork part of heat radiation wall, with the heating of heat radiation wall, the heat radiation wall that the quilt is heated is again with thermal -radiating form, with its absorptive heat transfer to boiler tube.
Description
Technical field
The utility model relates to a kind of tubular type square box-type heating furnace, especially installs the tubular type square box-type heating furnace of heat radiation wall additional at radiant section central part.
Background technology
By heat transfer type, tubular type square box-type heating furnace structurally can be divided into convection section and radiant section, as the term suggests it is based on heat radiation that radiant section refers to heat transfer type.According to the arrangement of boiler tube in radiant section, radiant section can be divided into single side radiation and the double-side radiation type of furnace further again, so-called single side radiation refers to boiler tube only can in the one-sided heat radiation accepting furnace wall, and double-side radiation then refers to boiler tube can accept furnace wall heat radiation in both sides.In simple terms, arrange if boiler tube presses close to furnace wall, burner is positioned at burner hearth central authorities, be then called the single side radiation type of furnace; Conversely, arrange if furnace wall pressed close to by burner, and boiler tube is arranged on burner hearth central authorities, be then called double-side radiation.That is, equiflux heater first radiant heat transfer is carried out to boiler tube in furnace wall heating, the furnace wall recycled by heating with flame.Because furnace wall directly contacts flame, and be heated to higher temperature, the larger temperature difference is formed with boiler tube, therefore, under normal circumstances, the heating furnace of double-side radiation, be all greater than single side radiation heating furnace, and single side radiation heating furnace has the advantages such as boiler tube arrangement convenience, cost is low, floor space is little at the radiant heat transfer total amount of radiant section, calorific intensity, the thermal efficiency.Therefore, high-power heating furnace many employings double-side radiation form, low-power heating stove many employings single side radiation form, two kinds of type of furnaces cut both ways.
Summary of the invention
In order to overcome the problem that single side radiation tubular type square box-type heating furnace calorific intensity is low, radiant heat transfer amount is little, the utility model provides a kind of novel pipe square box-type heating furnace.The same with common single side radiation square box-type heating furnace, boiler tube remain unchanged furnace wall arrange, burner is arranged in burner hearth central authorities equally, difference is, the heat radiation wall of hollow out is installed additional at the central flame envelope along burner flame of burner hearth, heat radiation wall directly and flame and smoke contacts, when smoke contacts or the openwork part through heat radiation wall, heat radiation wall is heated, by the heat radiation wall that heats again with thermal-radiating form, the heat absorbed is passed to boiler tube, form a kind of diabatic process being similar to equiflux heater, so, add heat radiation area in burner hearth, improve radiant heat transfer amount.
The technical problems to be solved in the utility model improves caloradiance and the heat output of single side radiation tubular type square box-type heating furnace.
It is as follows that the utility model solves the technical scheme that its technical problem adopts
Scheme 1: in single side radiation tubular type square box-type heating furnace central authorities, outside along burner flame installs two sides hollow out heat radiation wall additional, is crowded around by flame in the centre of heat radiation wall, and the spacing of heat radiation wall is according to the shape of flame, not affect fuel combustion for condition, flame flame envelope of trying one's best.The hollow out form of heat radiation wall and fretwork area unrestricted.
Scheme 2: in single side radiation tubular type square box-type heating furnace central authorities, the periphery along burner flame installs S shape hollow out heat radiation wall additional, the flame of every burner is crowded around respectively the central part at one section of C shape heat radiation wall, and opening portion is in the face of boiler tube.Heat radiation wall degree of crook according to the shape of flame, not affect fuel combustion for condition, flame flame envelope of trying one's best.Hollow out form and the openwork part area of heat radiation wall are unrestricted.
The beneficial effects of the utility model are, utilize the hollow out heat radiation wall installed additional, strengthen square box-type heating furnace radiant section caloradiance and radiant heat transfer amount.

Detailed description of the invention
Fig. 1 is the general illustration of embodiment of the present utility model, and the installation site of heat radiation wall in heating furnace (1) is in burner hearth central authorities, and heat radiation wall is crowded around all or part of for flame (2).Crowd around in the embodiment of flame in heat radiation wall part, the opening of heat radiation wall is towards heating furnace tube (3).
In embodiment illustrated in fig. 21, flame (2) is crowded around in central authorities by heat radiation wall (4), and heat radiation body of wall is hollow out (5) shape.
In embodiment illustrated in fig. 32, the flame (2) of every burner is crowded around the central authorities at one section of C shape cylinder radiant wall by S shape heat radiation wall (4) respectively, the opening of heat radiation wall is towards heating furnace tube, and heat radiation body of wall is hollow out (5) shape.
Claims (2)
1. a tubular type square box-type heating furnace, is characterized in that, in radiant section central authorities, installing hollow out heat radiation wall additional, crowded around by flame in the middle of hollow out heat radiation wall outside flame.
2. a kind of tubular type square box-type heating furnace according to claim 1, is characterized in that hollow out heat radiation wall is S shape, the flame of every burner is crowded around respectively the heat radiation wall central part one section of C shape.
