Abstract
An efficient energy-saving water-boiling boiler, comprises a water-boiling tank with a hearth provided at the bottom and a water preheating tank containing the lower section of the flue tube. And several heat-exchange water tubes communicating with the water-boiling tank are installed in the hearth adjacent to the top wall of the hearth, several heat-exchange water tubes communicating with the preheating water tank are installed in the heart adjacent to the two side walls of the hearth, and several rows of heat-exchange water tubes communicating with the preheating water tank are placed inside the flue tube of the section inside the preheating water tank. The heat exchange water tubes placed inside the hearth and the flue tube of the present utility model greatly enlarge the effectively heat transfer area of the water-boiling boiler, and fully utilize the heat produced by the fuel, increase the production efficiency of the water-boiling boiler, decrease the unit energy consumption apparently.
Description
Technical field
The utility model relates to a kind of water-storage heater, particularly boiler.
Background technology
Common fuel heating normal pressure boiler generally is made up of water tank and grate, is recessed into a cuboid space in the water tank bottom, the burner hearth that promptly acts as a fuel, the grate of burner hearth below is provided with grate, and the grate below is a cinder chamber, and upside draws and picks out flue tube behind the burner hearth.The boiler burner hearth heat transfer area of this structure is little, and fuel availability is low, and a large amount of heats enter atmosphere with flue gas, have wasted the valuable energy.For this reason, more existing boilers have been set up the preheating water tank, make the lower tube section of flue tube be positioned at the preheating water tank, absorb the part heat of flue gas with preheating water tank's water.Yet practice shows, because the flue gas flow velocity is very fast, and preheating water tank's insufficient height, the heat exchange area deficiency, the effluent gas temperature that enters atmosphere is still higher.Heat waste is still bigger.
Summary of the invention
The purpose of this utility model provides a kind of energy-efficient boiler, and the heat energy that fuel is produced is absorbed by boiled water tank and preheating water tank as far as possible, thereby improves the production efficiency of boiler, and energy savings.
Technical solution of the present utility model is: it comprises that the bottom is provided with the boiled water tank of burner hearth, and the preheating water tank of containing the flue tube lower tube section, and in burner hearth, press close to the burner hearth roof some heat exchange water pipes that are connected with boiled water tank are installed, press close to hearth biside wall some heat exchange water pipes that are connected with the preheating water tank are installed, in preheating water tank's flue pipeline section, also be provided with the heat exchange water pipe that plurality of rows is connected with the preheating water tank simultaneously.
The heat exchange water pipe that the utility model is provided with in burner hearth and flue tube has increased effective heat transfer area of boiler greatly, has made full use of the heat energy that fuel produces, and has improved boiler production efficiency, has reduced specific energy consumption greatly.

The specific embodiment
The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.
The boiled water tank 8 and the preheating water tank 13 that amplexiform mutually are installed on the grate 16.Boiled water tank 8 bottoms are provided with upwards that the flute profile space of indent promptly constitutes burner hearth 3, and burner hearth 3 rear wall tops are to offer floss hole on preheating water tank's wall, are connected with straight up flue tube 10, and the middle and lower part of flue tube 10 is arranged in the preheating water tank; The burner hearth bottom surface is that grate 16 bearing-surfaces are provided with grate 2, and grate 2 belows are cinder chamber 1.In order to improve heat transfer efficiency, be that the boiled water tank bottom surface is provided with several heat extraction exchange water pipes 6 pressing close to the burner hearth roof, each heat exchange water pipe 6 runs through burner hearth left and right sides wall, and two-port is connected with boiled water tank 8; Also respectively be provided with heat exchange water pipe row 5 pressing close to hearth biside wall, each heat exchange water pipe is arranged 5 rear ends and is passed the preheating water tank wall and be connected with preheating water tank 13, and it is outer and seal with cock 4 silently that front port is exposed to the boiled water tank antetheca.In addition, installed in flue tube 10 middle and lower parts also that the plurality of rows level runs through flue tube and the heat exchange water pipe 14 that is connected with preheating water tank 13.Above-mentioned heat exchange water pipe 5,6 and heat exchange water pipe 14 are straight length, are convenient to the incrustation scale in the daily cleaning pipe like this.Boiled water tank 8 tops are provided with blow-down pipe 9, and the bottom is provided with heat water valve 7, and preheating water tank 13 tops are provided with blow-down pipe 11, and top is provided with water intaking valve 12, between boiled water tank 8 and preheating water tank 13 bottoms communicating valve 15 are installed.
Claims (2)
1, a kind of energy-efficient boiler, comprise that the bottom is provided with the boiled water tank (8) of burner hearth (3), and the preheating water tank (13) of containing flue tube (10) lower tube section, it is characterized in that in burner hearth (3), pressing close to the burner hearth roof some heat exchange water pipes (6) that are connected with boiled water tank (8) are installed, press close to hearth biside wall some heat exchange water pipes (5) that are connected with preheating water tank (13) are installed, in preheating water tank's (13) bright road pipeline section, also be provided with the heat exchange water pipe (14) that plurality of rows is connected with preheating water tank (13) simultaneously.
2, by the described energy-efficient boiler of claim 1, it is characterized in that heat exchange water pipe (5), (6) and heat exchange water pipe (14) are straight length.
