Abstract
A non-pressure boiler with a heightened hearth and a spiral flue formed by winding a plurality of large-lead spiral fire tubes. In the boiler, the flue resistance is small, no dust is accumulated in the flue, no heat exchange dead zone is formed, and the smoke concentration is 185mg/NM3The thermal efficiency is 75% below.
Description
The utility model relates to a kind of pressure-less boiler, is a kind of drinking water that provides, the pressure-less boiler of waters such as heating, steamed rice, bathing.
Pressure-less boiler is owing to eliminate hidden peril of explosion fully, and possess thermal efficiency height, economize on coal, favorable factor such as cost is low, use more and more generally, become the regeneration product of boiler gradually.
The pressure-less boiler of Shi Yonging how by housing, is arranged on the combustion chamber of housing bottom now, is positioned at the burner hearth of the built-in heat exchange water pipe above the combustion chamber, and the flue on housing top constitutes.In order to increase heating surface area, some pressure-less boilers as No. 91210737.5, Chinese patent, disclose a kind of multifunctional and energy-saving drinking water boiler technology.The energy-conservation drinking water boiler of this kind is provided with secondary water tank in burner hearth, mounting disc tube heater in the secondary water tank is arranged the iris type heater in flue, makes the repeatedly revolution of flue gas stream, forms many backhauls exhaust gases passes.This drinking water boiler heating surface area is big, and flue gas resistance is little, the heat utilization efficiency height, heat up also very fast.Weak point is that iris type heater root can form cigarette flame stream dead band, and temperature is low, and the heat exchange condition is poor, and easily forms black dirt, influences the overall thermal efficient of this stove.
At the above-mentioned deficiency of existing pressure-less boiler technology, the pressure-less boiler that the purpose of this utility model provides a kind of province coal, cost and operating cost further reduces, the thermal efficiency further improves.
Above-mentioned purpose of the present utility model realizes by following technical measures:
By housing, be arranged on housing bottom the combustion chamber, be positioned at the burner hearth of the built-in heat exchange water pipe above the combustion chamber, and the pressure-less boiler that flue constituted that is arranged in the top, combustion chamber, its flue is twined by a plurality of big helical pitch spiral pyrotechnics pipes to be formed.
The employing of big helical pitch spiral pyrotechnics pipe, not only can significantly increase the heating surface area of smoke flue, help the heat exchange of flue part, and, flue resistance is little, and flue gas flow rate is low in the spiral flue, and flue gas flow rate can be 1.54M/S, spiralling flue gas can accumulated soot, does not form the heat exchange dead band.The inside and outside footpath size of suitable selection spiral pyrotechnics pipe, number, the lead angle of spiral pyrotechnics pipe cooperate and increase known technology measures such as chimney, twice aeration, can make thermal efficiency convergence 75%, and dust concentration is at 185mg/NM
3Below, lingemann blackness is below 1 grade.
If take to increase burner hearth 1.2-1.5 times again to common identical heating load pressure-less boiler burner hearth, increase the radical of heat exchanging water pipe in the burner hearth, cooperate secondary wind to strengthen inner flue gas of the stove and mix, can make fuel completing combustion, fully emit heat, its thermal efficiency can reach 75%.
If with the lead angle of spiral pyrotechnics pipe, be chosen between lift angle 48-53 ° of internal diameter, between the lift angle 25-30 of maximum cylindrical °,, reach that to economize the index of coal 23% than the existing pressure-less boiler of same heating load more favourable to reaching 75% the thermal efficiency.
Accompanying drawing is the structural representation of pressure-less boiler provided by the utility model.Below in conjunction with accompanying drawing,, further narrate technical characterictic of the present utility model by most preferred embodiment.
Pressure-less boiler is made of housing (9), the combustion chamber (12) that is arranged on housing bottom, the flue that is positioned at the burner hearth (10) of the built-in heat exchange water pipe (4) above the combustion chamber and is positioned at the top, combustion chamber.Its flue is by four uniform being welded on the burner hearth top board, and external diameter is φ 1000mm, internal diameter φ 400mm, and helical pitch is that the spiral pyrotechnics pipe of 1500mm twines formation.The lead angle of spiral flue (5), 50 ° of the lift angles of internal diameter (on the flue core pipe face), 25 ° of maximum cylindrical lift angles.
Burner hearth (10) is increased to 1.35 times of the pressure-less boiler burner hearth of existing same heating load.
In the present embodiment, outlet flue left and right sides symmetric arrangement is led to smoke-box (8).Each one of every side whole circle spiral pyrotechnics pipe and 3/4 circle pyrotechnics pipe.The threeway chimney seat with symmetry about the flue gas that outlet flue compiled of distribution both sides from main chimney with the cigarette emptying.Dispose main chimney height and should more than 13M,, be convenient to gravity-flow ventilation and smoke evacuation to guarantee draft.
In the structural representation, (1) is fire grate, and (2) are secondary air channel, and (3) are water inlet pipe, and (6) are delivery port, and (7) are atmosphere connection port, and (11) are the dewatering outlet, and (13) are sewage draining exit.
In the present embodiment, furnace shell external diameter φ 1200mm, burner hearth internal diameter φ 1120mm, furnace height 1450mm, heating load 0.49MW.
Claims (3)
1, a kind of pressure-less boiler, by housing, be arranged on housing bottom the combustion chamber, be positioned at the burner hearth of the built-in heat exchange water pipe above the combustion chamber, and the flue that is positioned at the top, combustion chamber constitutes, and it is characterized in that, its flue is twined by a plurality of big helical pitch spiral pyrotechnics pipes to be formed.
2, pressure-less boiler according to claim 1 is characterized in that increasing burner hearth 1.2-1.5 times to common pressure-less boiler burner hearth.
3, pressure-less boiler according to claim 1 and 2 is characterized in that the lead angle of spiral pyrotechnics pipe, 50 ° of the lift angles of internal diameter, and 25 ° of maximum cylindrical lift angles, 4 spiral pyrotechnics pipes, furnace height are 1.35 times of identical heating load furnace height.
