The utility model has the advantages that the structure is simple; the dust removal effect is good; the functions of heating, bathing and boiling water supply are realized on one boiler; the heat efficiency is higher; the Ringelman blackness is smaller than 1; the weight is light; the volume is small; the utility model can be used in traveling area.

Description

Power-saving vertical water pipe normal-pressure boiler

The utility model relates to boiler manufacturing technology field, and exactly it is a kind of power-saving vertical water pipe normal-pressure boiler.

At present, the normal-pressure boiler model of selling on the market, various in style is used in heating more, has a bath and supplies on the drinking water.Multi-use is also arranged.These boilers adopt the double grate structure more, though improved dust removing effects, but still undesirable, and the thermal efficiency is not high yet.In addition, there is complex process in the structure of existing boiler on making, and makes the shortcoming of inconvenience.

The purpose of this utility model provides a kind of good dustproof effect, reaches tourist district's discharge standard, can heating, have a bath, for three usefulness, that the thermal efficiency the is high and better simply power-saving vertical water pipe of the production technology normal-pressure boiler of boiling water.

The purpose of this utility model is achieved by the following scheme, it is made up of furnace shell and combustion chamber two large divisions, combustion chamber is made of two burner hearths, two flues, dust cleaning case, waste heat case and boiled water tanks again, it is characterized in that: in burner hearth (23) (24) and dust cleaning case (20), be furnished with hot water overflow pipe (21) (22), dust cleaning case (20) upper end directly communicates in stove stack extension (19), the left side directly is communicated with following burner hearth (24) with the vertical gas pass (25) that dust cleaning case (20) connects together, and fire grate (17) is a single layer fixed fire grate.Be connected with steam combustion tube (16) in the lower hearth bottom.

The utility model has the advantages that, it is more reasonable to design, of a tightly knit structure, gravity-flow ventilation does not need forced-and-induced draft fan equipment, does not need to be provided with in addition cleaner yet, smoke elimination, dedusting are closed in one, lingemann blackness≤1, steam added combustion has improved the thermal efficiency, thereby has reached efficient, energy-conservation, small investment, requirement that floor space is little.In addition, heating, have a bath, do not circulate mutually for boiling water three water systems, stop heating after, have a bath, still can normally carry out for boiling water.Have the adaptability of being exactly strong again, coal is not limit, and is safe and reliable, the normal pressure operation.

Below in conjunction with accompanying drawing the utility model is done further detailed description.

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model A-A cutaway view,

Fig. 3 is the utility model right view.

1 is furnace shell among the figure, and 2 is combustion chamber, and 3 is manhole cover, and 4 is the water level meter, 5 is the ash door, and 6 is the air register handle, and 7 is the backwater flange, and 8 is fire door, 9 is hand hole, and 10 is that gap 11 is thermometer, and 12 is the delivery port flange, and 13 is the boiled water tank tube connector, 14 is boiled water tank, and 15 for inserting the water hole, and 16 is the steam added combustion pipe, and 17 is fire grate, 18 is the waste heat case, and 19 is stove stack extension pipe, and 20 is dust cleaning case, and 21 is last to overflow pipe, 22 is to descend overflow pipe, and 23 is upper furnace, and 24 is lower hearth, and 25 is vertical gas pass.Producing equipment of the present utility model and technology and existing boiler makes basic identical.Furnace shell is water leg on four sides, relies on the fume afterheat heating to go up the water in the overflow pipe, leans on the proportion of hot and cold water to make bathing water carry out Natural Circulation to overflow pipe and between down to overflow pipe by the boiled water tank tube connector last.After clean-out cover (3) is opened, can stretch out one's hand easily after the blowing out cooling into the interior dust stratification of removing.Directly add the heat supply drinking water with lower hearth.The hot water that is used for heating supplies heating usefulness through delivery port (12), returns boiler through water return outlet (7) again.Gap (10) is too high in order to the water level that shows water jacket.During summer, can the single fire lower hearth for the drinking-water and the usefulness of having a bath, fuel savings greatly.Fire grate is a casting furnace grate.Row's number to overflow pipe is set when specifically manufacturing up and down as required.When the user uses, install, if to have a bath, heating again, boil water,, need be provided with one in addition than large water tank and boiler body forced circulation then because of the bathing water amount is big according to the instructions for use of our unit; If boiler just is used for boiling water, then pipeline is the simplest, only water inlet pipe, outlet pipe need be connected respectively to get final product.Owing to the utlity model has two burner hearths up and down, made full use of fume afterheat, make burning safer, improved the thermal efficiency.The lower end of vertical gas pass directly communicates with fire grate, has not only improved combustion position and dust removing effects, and can make the dust stratification of vertical gas pass directly discharge ashpit by fire grate.The utility model has adopted single fire grate structure in addition, and it is comparatively easy that manufacturing is installed.

Claims (2)

1, power-saving vertical water pipe normal-pressure boiler, it is made up of furnace shell and combustion chamber two large divisions, combustion chamber is made of two burner hearths, two flues, dust cleaning case, waste heat case and boiled water tanks again, it is characterized in that: in burner hearth (23) (24) and dust cleaning case (20), be furnished with hot water overflow pipe (21) (22), dust cleaning case (20) upper end directly communicates in stove stack extension (19), the left side directly is communicated with following burner hearth (24) with the vertical gas pass (25) that dust cleaning case (20) connects together, and fire grate (17) is a single layer fixed fire grate.
