Abstract
The invention relates to a large horizontal steam boiler with a front diaphragm-wall hearth fire tube convection heating surface. The large horizontal steam boiler comprises a hearth (1), a combustion chamber (2), a shell (4), a rear smoke chamber (5) and an energy saver (6), and is characterized in that the hearth (1) and the shell (4) are horizontally arranged, the hearth (1) is arranged in front of the shell (4) and communicated with the same (4), a smoke tube (3) is arranged in the shell (4), and the hearth (1) and the combustion chamber (2) are of a water diaphragm wall structure. Due to the fact that a plurality of combustors combined with the heating surface of the smoke tube are arranged in the front diaphragm-wall hearth, the boiler with full equipment and large-scale design can be realized.
Description
Technical field
The present invention relates to a kind of horizontal steam boiler.Applicable combustion heavy oil, the contour pollution feul of coke-stove gas.Belong to the heating equipment technical field.
Background technology
At present, China's energy consumption per unit of output value is 2.3 times of world average level, and main energy-consuming product specific energy consumption is higher by 40% than Foreign Advanced Lerel; The energy consumption of one dollar of GNP of the every creation of China is 4.97 times of Germany, 4.43 times of Japan, 2.1 times of the U.S., 1.65 times of India, this be cause that entreprise cost rises, one of major reason of deficiency in economic performance.According to investigations, China's industrial products energy, raw-material consumption account for 75% left and right of enterprise's production cost, if reduce one percentage point, just can obtain the benefit of more than 100 hundred million yuan.
Recent two decades comes, and on the one hand, the development rate of oil, natural gas improves greatly, and country has cancelled the restriction that large-and-medium size cities use oil product and natural gas; On the other hand along with the enhancing of global environmental consciousness, Chinese national economy develops rapidly, living standards of the people improve constantly, China adjusts the fuel policy, for environmental pollution and the air quality of improving large-and-medium size cities, government starts to encourage public enterprises and institutions to use oil product or natural gas, has greatly accelerated the development of oil-burning gas-fired boiler.
In the development of fuel-firing gas-firing Industrial Boiler, the fuel-firing gas-firing Industrial Boiler type of furnace that China mainly introduces, produces is horizontal three return stroke wet back type fire tube structures, because its compact conformation, volume are little, self-contained, dispatch from the factory, take up an area less, automaticity is high, be subject to manufacturer and user's favor, " horizontal three return stroke wet back type multitubular boilers " have almost become the synonym of fuel-oil or fuel-gas boiler.But this kind boiler is because being subjected to the restriction of its structure, and fuel-firing gas-firing steam boiler maximum can only be accomplished 20t/h, makes this boiler to provide steam for midget plant, enterprises and institutions.
Keeping, under little, the self-contained front load of dispatching from the factory, taking up an area few advantage of horizontal three return stroke wet back type multitubular boiler compact conformations, volume, whether can expanding thinking, design a kind of large-scale fuel-firing gas-firing steam boiler.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of and realize maximizing, the horizontal steam boiler of self-containedization.
The first purpose of the present invention is achieved in that a kind of preposition membrane wall burner hearth fire tube convection heating surface large-size horizontal steam boiler, comprise burner hearth, burning chamber, shell, rear smoke box and energy-saving appliance, it is characterized in that: burner hearth and horizontal-housing type are arranged, burner hearth is placed in the shell front side, and be connected with shell, shell is built-in with smoke pipe, and described burner hearth and burning chamber all adopt the water pipe membrane wall structure.
The preposition membrane wall burner hearth of the present invention fire tube convection heating surface large-size horizontal steam boiler, described burner hearth adopts a plurality of burner arrangement.
The preposition membrane wall burner hearth of the present invention fire tube convection heating surface large-size horizontal steam boiler, at the membrane wall lower header of burner hearth and the connector of shell, be provided with nozzles with injector.
Energy-saving appliance of the present invention adopts coiled pipe energy-saving appliance structure.
The invention has the beneficial effects as follows:
1, the present invention is in conjunction with water pipe and multitubular boiler characteristics separately, the burner hearth that space hold is larger and burn part and adopt the water pipe membrane wall structure, by preposition membrane wall burner hearth, simultaneously convection heating surface adopts the smoke pipe of compact conformation, makes that fire tube boiler is self-contained, maximizing becomes possibility.
2, the present invention adopts the injection drainage technology, strengthens burner hearth membrane wall pipe hydrodynamic force, guarantees the operation of boiler effective and safe.
3, multi-combustor design of the present invention, many operating fuels, the applicable combustion heavy oil of this boiler, the contour pollution feul of coke-stove gas.

The specific embodiment
Referring to Fig. 1, Fig. 1 is the preposition membrane wall burner hearth of the present invention fire tube convection heating surface large-size horizontal steam boiler general structure schematic diagram.As seen from Figure 1, the preposition membrane wall burner hearth of the present invention fire tube convection heating surface large-size horizontal steam boiler, comprise burner hearth 1, burning chamber 2, smoke pipe 3, shell 4, rear smoke box 5 and energy-saving appliance 6, burner hearth 1 and the horizontal layout of shell 4, burner hearth 1 is placed in shell 4 front sides, and be connected with shell 4, burning chamber 2 is placed in burner hearth 1 rear portion, and smoke pipe 3 is placed in shell 4, and rear smoke box 5 is placed in shell 4 rear sides, and be connected with shell 4, energy-saving appliance 6 is placed in rear smoke box 5 tops.
Described burner hearth 1 and burning chamber 2 all adopt the water pipe membrane wall structure.
Described energy-saving appliance 6 adopts coiled pipe energy-saving appliance 6 structures.
Boiler feedwater process energy-saving appliance 6 heating absorption waste heats, then, to burner hearth 1 and burning chamber 2, finally enter in shell 4, further heating produces steam, and shell 4 internal heating surfaces are smoke pipe 3.
By above-mentioned design, the larger burner hearth 1 that takes up room is adopted to the water pipe membrane wall structure, convective region adopts smoke pipe 3 structures, makes boiler whole height and width reduce and reduces; Simultaneously, burner hearth 1 adopts multi-combustor to arrange (two, three or four layouts), has greatly shortened size of burner hearth; Smoke pipe 3 adopts low flow velocity, and the design of enhanced heat exchange face, also further shortened shell 4 length.These particular design all guarantee that boiler integral body is limited in the scope of a suitable domestic highway transportation, thereby realize maximization, self-containedization that the present maximum of this self-contained type of furnace can be accomplished 50 tons/hour.
The present invention is also at the membrane wall lower header of burner hearth and the connector of shell, be provided with nozzles with injector, by the injection of high-velocity flow, the stove water around driving enters the membrane wall lower header of burner hearth, strengthen the hydrodynamic force of the membrane wall of burner hearth, guarantee preposition membrane wall burner hearth reliability service.
Burner hearth 1 of the present invention and burning chamber 2 all adopt the water pipe membrane wall structure, and on membrane wall, have opened 4 manholes; Convective region adopts flue structure, and has established manhole on rear smoke box, is convenient to clean; At rear smoke box 5 tops, be provided with the energy-saving appliance 6 of coiled pipe, with bolts between the two, detachable.These characteristics make this boiler oil scope of application further enlarge, and burning heavy oil, the contour pollution feul of coke-stove gas have enlarged the applicability of boiler, have enlarged the scope of application of boiler.
