Description

Horizontal boiler for heating water

Technical field

The utility model is related to a kind of Horizontal boiler for heating water more particularly to a kind of hot-water boilers of no return combustion chamber.

Background technology

As atmosphere pollution getting worse, the energy are increasingly deficient, high pollution, high energy consumption enterprise must carry out energy-saving and emission-reduction, The coal type fuel of heating boiler has been altered in steps as oil, gas type fuel, and steam heating also transitions into hot water heating, horizontal WNS type heating boilers are more universal, and in the design process for substituting horizontal steam boiler with Horizontal boiler for heating water, it is primarily present Following technical problem：There are the arrangement of return combustion chamber and the pipe that strile-backs, join domains, have thus inevitably enlarged boiler volume；Boiler water Volume increases, and starts slow；Boiler is without specific water side rise and fall region, and boiler return combustion chamber front tube sheet water temperature is uncontrollable, pot Stove service life is reduced；In addition, steel consumption is big, installation space is big.

Utility model content

The purpose of this utility model is to provide that a kind of small, steel consumption is few and horizontal water bath with long service life Stove.

To achieve the above object, the utility model uses following technical scheme：A kind of Horizontal boiler for heating water, including boiler Shell, the horizontal arrangement of boiler shell, horizontal in boiler shell to be disposed with flue, the center line of flue is less than the center of boiler shell Having between the front end of line, boiler shell and flue has boiler end plate between boiler front end-plate, rear end, after flue tube sheet and boiler It is horizontal between end plate to be disposed with first group of smoke pipe, the horizontal arrangement of area top and side between the boiler shell and flue There is second group of smoke pipe, the both ends of second group of smoke pipe extend to the outside of boiler front end-plate, boiler end plate, in first group of smoke pipe End is connected to the burner hearth in flue, and the rear end of first group of smoke pipe is connected to second group of smoke pipe outside boiler end plate, boiler shell Inlet tube and outlet tube is disposed on body.

Above-mentioned technology and the prior art are most significant, and difference lies in boiler constitutes three backhauls heat exchange without return combustion chamber Process, one is burner hearth ranging from the first backhaul；The second is first group of smoke pipe location constitutes the second backhaul；The third is second Group smoke pipe location constitutes third backhaul.The utility model eliminates return combustion chamber and makes the furnace body length of burner hearth length direction aobvious Reduction is write, steel consumption is substantially reduced, and welding position substantially reduces, while ensure that the heat exchange of three return strokes, it is ensured that heat is handed over Change efficiency.

Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model；

A-A, B-B sectional view in the respectively Fig. 1 of Fig. 2,3.

Specific implementation mode

Referring to Fig. 1, Horizontal boiler for heating water, 10 horizontal arrangement of boiler shell is horizontal in boiler shell 10 to be disposed with flue 20, The center line of flue 20 is less than the center line of boiler shell 10, there is boiler front end-plate between boiler shell 10 and the front end of flue 20 30, there is boiler end plate 40 between rear end, it is horizontal between flue tube sheet 21 and boiler end plate 40 to be disposed with first group of smoke pipe 50, Area top and side between the boiler shell 10 and flue 20 are horizontal to be disposed with second group of smoke pipe 60, second group of smoke pipe 60 both ends extend to the outside of boiler front end-plate 30, boiler end plate 40, the inner end of first group of smoke pipe 50 in flue 20 Burner hearth is connected to, and the rear end of first group of smoke pipe 50 is connected to second group of smoke pipe 60 outside boiler end plate 40, on boiler shell 10 It is disposed with inlet tube and outlet tube 11,12.

The utility model disclosed in above-mentioned technical proposal actually belongs to three backhauls without return combustion chamber hot-water boiler, three backhauls It is burner hearth backhaul, first group of smoke pipe 50 and second group of 60 location of smoke pipe respectively, implements to exchange heat by above-mentioned three times, it can be ensured that Heat exchange efficiency, while the length that return combustion chamber efficiently reduces horizontal boiler is eliminated, it is also corresponding to reduce due to eliminating return combustion chamber The highly difficult welding of corresponding position.

Preferably, horizontal between the flue tube sheet 21 and boiler end plate 40 to be disposed with process duct 70, work The inner end of skill pipe 70 is connected to the burner hearth in flue 20, access door 71 is arranged in outer end, process duct 70 and 20 same core of flue arrangement, institute The first group of smoke pipe 50 stated is disposed around around process duct 70.

Second group of smoke pipe 60 is arranged in side, upper lateral part and the upper area model of flue 20 and first group of smoke pipe 50 In enclosing.

Said program eliminates the most upper smoke exhaust pipe of three pass hot water boiler of common horizontal in the prior art to shell cylinder The carbonated drink space of this space, that is, original steam boiler is reduced significantly shell barrel diameter, and formation is abound with pipe hot-water boiler, to subtract Small furnace body volume reduces steel consumption.

It is 0.68 times of existing conventional boiler since water capacity of the boiler is reduced, boiler startup is quick, load responding is fast, stores Heat is small, and low energy consumption；Boiler provided by the utility model has specific up and down region, first group of 50 entrance of smoke pipe i.e. One smoke pipe 50 and the water temperature of 21 junction of flue tube sheet are higher than conventional boiler by 20, can effectively prevent 21 cracking phenomena of flue tube sheet Generation.Arrow in Fig. 2 indicates that the water (flow) direction in decline region, the arrow in Fig. 3 indicate the water (flow) direction of elevated areas.

Inlet tube and outlet tube 11,12 is arranged in the top of 10 leading portion of boiler shell, back segment, and 10 top of boiler shell is also set It is equipped with pressure gauge, exhaust steam valve.Above-mentioned attachment, which is arranged, can ensure to understand the operating mode of boiler and ensure safe operation.
