Description
Technical field
The utility model relates to a kind of wet back type fire-tube hot-water boiler.Belong to heating equipment technical field.
Background technology
At present, China's energy consumption per unit of output value is world average level 2.3 times, 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, 1.65 times of 2.1Bei， India of the 4.43 Bei， U.S. of Japan, 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 fuel policy, for improving environmental pollution and the air quality of 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 of boiler is because being subject to the restriction of its structure, and boiler peak power output can only be accomplished 14MW, makes this type boiler can only be applicable to the places such as hotel, hospital, small community heating.
Keeping, under little, the self-contained prerequisite 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 further breaking through boiler load restriction, promote the designed capacity of horizontal internal combustion boiler.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of hot-water boiler that can greatly improve the EIAJ of boiler is provided.
The purpose of this utility model is achieved in that a kind of water pipe membrane wall structure return combustion chamber water-cooled wet back type fire-tube hot-water boiler, comprises flue, return combustion chamber, two return smoke pipe, energy-saving appliance, shell, front smoke box, turning flue, exhaust pass and burner, described flue and two return smoke pipe are arranged in shell from bottom to top, front smoke box is arranged at the front side of two return smoke pipe, turning flue is arranged at front smoke box top, and energy-saving appliance is built in turning flue, and exhaust pass is arranged in front smoke box rear side, be connected with front smoke box, it is characterized in that described return combustion chamber is placed on shell rear portion, described return combustion chamber adopts membrane wall structure, described flue, two return smoke pipe, energy-saving appliance and burner are provided with two, two flues, two return smoke pipe and energy-saving appliance all left and right are arranged side by side, described return combustion chamber, in the middle of front smoke box and turning flue, be provided with demarcation strip, this demarcation strip is by return combustion chamber, front smoke box and turning flue are separated into two, described two burners, two flues, two return combustion chambers, two two return smoke pipes, two front smoke boxs, two turning flues and two energy-saving appliances form completely independently flue gas flow system of two covers, finally by an exhaust pass, are gathered and are entered chimney.
The beneficial effects of the utility model are:
1, the utility model makes by conventional wet being carried on the back to return combustion chamber the external return combustion chamber forming with membrane wall structure into, has greatly reduced the space hold in shell; Do not increasing under the prerequisite of flue size simultaneously, adopt double-flow, two return design, greatly reduced space, increased heating surface layout, broken through old-fashioned full wetting back-type return combustion chamber because of structural limitations, cannot do large design bottleneck, making to design large capacity, self-contained, fuel-firing gas-firing, Horizontal boiler for heating water becomes possibility.For the design of large-scale self-contained horizontal internal-combustion hot-water boiler provides a kind of brand-new mentality of designing.Adopt after this structure, the design maximum ability of this fuel-firing gas-firing horizontal internal-combustion hot-water boiler has reached 35MW.
2, boiler adopts double burner, dual-furnace-chamber, two cover two return smoke pipes, dual economizer, the membrane wall structure return combustion chamber, front smoke box and the turning flue that adopt band to separate simultaneously, form completely independently flue gas flow system of two covers, finally by an outlet flue, gather and enter chimney.By these measures, guarantee burner independent operating completely, greatly increased the load regulation range of boiler, making the Load Regulation of boiler compare single burner has increased by one times, has met the requirement of user for underload.
3, boiler blow-down water is from energy-saving appliance heat absorption heats up, and enters immediately membrane wall return combustion chamber, finally enters shell, from the water outlet of shell top, has formed the water circulation system of boiler.For this reason, boiler water cycle has been designed to forced circulation, adopts water flow mode from bottom to top simultaneously, thereby guarantees that membrane wall structure can obtain effective cooling.
4, optimal design water-cycling mode, take afterbody water intake mode, guarantee that membrane wall return combustion chamber, two return smoke pipe enter the augmentation of heat transfer position effective coolings such as cigarette place, water circulation is reliable.
