Abstract
The utility model relates to a constant-pressure hot-water briquette boiler adopting the horizontal type as the form of the main body of the boiler, which primarily resolves the technical problems of the prior hot-water briquette boiler that the gas flow distance is long, the gas flowing resistant force is large and the service life of the parts is short. The technical proposal of the utility model is to arrange a beacon pipe that forms a single-return flue flow passage with the flowing direction of the beacon of a combustion chamber inside a water jacket that is arranged above the combustion chamber. The technology has the characteristics of less beacon resistant force, high heat-exchanging efficiency and long normal-operation period.
Description
It is the technological improvement of the atmospheric hot-water molded coal boiler of boiler body form with horizontal that technical field the utility model relates to a kind of.
What the background technology present technique was related is that the atmospheric hot-water molded coal boiler is horizontal upper ignition coal briquette boiler, and the basic structure of this boiler is that the top, combustion chamber is water jacket or the water tank that wears some pyrotechnics pipes, and water jacket communicates with below collection case by water screen tube.Existing this type of boiler is in order to make full use of flue gas heat energy on structural design, especially designed in water jacket by two-layer pyrotechnics pipe flue that constitute, that make the flue gas rotary trend up and down, constituted two backhaul flue gas flow channels jointly with the flue gas trend of combustion chamber.Though the horizontal molded coal boiler of this pair of backhaul flue structure can be realized abundant heat exchange by convection heating surface, but caused the low excessively technology disadvantage of its smog discharge temperature, its smog discharge temperature is only about 120 ℃, because under this temperature environment, be easy to dewfall in the chimney and interact and make the corrosion of chimney large tracts of land with sulphur in the flue gas, only the chimney that is corroded of heating phase just must repair and replacement usually.And this also has that the inner flue gas of the stove flow process is long, the flow of flue gas resistance strengthens, thereby has to increase chimney height, enables the bigger air inducing equipment of power, and usually its chimney height has strengthened cost of installation and use up to 20 meters.So in sum, prior art is still imperfect.
Summary of the invention is long for the flue gas flow that solves existing horizontal molded coal boiler existence, flow resistance is big, smog discharge temperature is crossed technical problems such as low, the atmospheric hot-water molded coal boiler that the utility model proposes, the main contents of its technical scheme are described molded coal boiler, its boiler body structure is: its top, combustion chamber is for wearing the water jacket of some pyrotechnics pipes, this water jacket communicates by being communicated with water channel with below collection case, the major technique characteristics of this technical scheme are to be provided with one deck pyrotechnics pipe in the water jacket, the flue gas trend of combustion chamber has constituted single backhaul flue structure jointly with this pyrotechnics pipe, and the back smoke box of pyrotechnics pipe end is provided with the flue gas outlet.
In above-mentioned technical scheme, be connected by the water-cooling wall water jacket of being located at the combustion chamber inwall between water jacket and the below collection case; The furnace wall of the pyrotechnics pipe front end of water jacket is provided with to the water jacket below and extends the fire-resistant reflection chimney arch that is provided with, and fire-resistant reflection chimney arch makes the preceding end spaces of the pyrotechnics pipe of its top water jacket form front smoke box.
The present patent application key problem in technology is to have adopted individual layer pyrotechnics tubular construction in water jacket, this pyrotechnics pipe is connected with the flow of flue gas trend of combustion chamber, constituted single backhaul flow of flue gas working method jointly, present technique is fully realizing on the basis of boiler output, by shortening flue gas flow, reduced flue gas resistance, reduced the power setting of the air inducing facility of boiler, strengthened the heat-conductive characteristic between flue gas and the water jacket, particularly the setting of individual layer pyrotechnics pipe significantly reduces the thickness of water jacket, accelerated the water jacket programming rate effectively, thereby the medium circulation ability of boiler body is improved greatly.In addition, because in the technical program, substituted the water jacket furnace arch structure of existing boiler front smoke box below by fire-resistant reflection chimney arch, this the reflection chimney arch almost with the synthermal variation of flue gas, and to its top water jacket play the baking effect, avoided the delay of flue gas, further improved flow of flue gas situation in its body of heater, made the working condition of boiler more be tending towards perfect at front smoke box.
Below in conjunction with specifically implementing structure, particularly describe technology contents of the present utility model in detail as the given concrete enforcement structure of figure.
Description of drawings
Fig. 1 is the inside sectional structure schematic diagram of the utility model molded coal boiler
Fig. 2 is the A-A sectional structure schematic diagram of Fig. 2.
Specific embodiment atmospheric hot-water molded coal boiler of the present utility model, be to constitute by the four body of heater unit that have same structure up and down, the molded coal boiler of single body of heater unit can be designed in the reality according to actual needs, the molded coal boiler of two body of heater unit up and down can also be designed.Its each body of heater cellular construction includes heating surface---the water jacket 3 or 14 of combustion chamber 1 or 8, top, combustion chamber, is provided with a smoke evacuation fire tube 2 or 7 in the water jacket, and the front end of this pyrotechnics pipe communicates with the hot-zone of giving of combustion chamber.The end of pyrotechnics pipe feeds back smoke box 6, the smoke stack emission flue gas that is communicated with by the flue gas outlet 13 of back smoke box 6.Vertical furnace wall place of the pyrotechnics pipe front end of water jacket is provided with to the water jacket below extends the fire-resistant reflection chimney arch 15 or 16 that is provided with, fire-resistant reflection chimney arch 15 or 16 existence, make before the pyrotechnics pipe of its top water jacket the cold air space of end spaces and coal supply end isolated, constitute front smoke box 4 or 17, because this fire-resistant reverberatory furnace arch structure, just can not resemble the existing water jacket chimney arch technology before flue gas enters the pyrotechnics pipe and its heat exchange, and the bigger thermal losses of generation, and make flue gas be stranded in the technology disadvantage of front smoke box 4 or 17, help the flue gas circulation.In addition in present technique, water-cooling wall water jacket 10,11 between the levels 3 and 14, by being located at the combustion chamber inwall between water jacket 14 and the below collection case 9, or claim boxboard formula water jacket to communicate, this structural change the connected mode of water screen tube, thereby avoided because of pipeline obstruction that the cold wall pipe fouling is caused, influenced the phenomenon that water circulation and boiler run well and the life-span of prolonged boiler normal operation work occurs.Each body of heater unit can constitute required monolithic devices coal burning boiler mutually, and the combustion chamber of each body of heater unit is separate, and its flue gas is by the terminal set back smoke box 6 of each pyrotechnics pipe, central exhaust.
