CN2146654Y - Hot-tube atmospheric horizontal boiler - Google Patents

Abstract

The utility model relates to a hot-tube atmospheric horizontal boiler which is characterized in that a double-layer water-tube grate and two burning chambers are all provided with inclined water-cavity smoke blocking plates and vacuum hot tubes in orderly arrangement. A screw-thread fire tube and mutually staggered water-cavity fume grates are arranged on the second burning chamber, the highest point of which is provided with a spherical air exhausting dust remover, and a heating system is provided with an automatic pressure reducer. The utility model doesn't need to be provided with a blower, a draught fan and an auxiliary dust remover. The hot-tube atmospheric horizontal boiler has the advantages of high thermal efficiency, fuel, energy, steel and fund saving, environmental pollution reduction, safe and reliable operation, easy production and no smoke and noise, and can be produced by general boiler plants.

Description

Hot-tube atmospheric horizontal boiler

The utility model belongs to the heating technology field.

The vertical boiler of having invented (patent No. 90209250.2) is that 2/3 vacuum heat-pipe has been introduced vertical boiler, and result of use is fine, thermal efficiency height, and 40-50% economizes on coal, and do not have flue dust, noiselessness has significantly reduced environmental pollution, the operation of this boiler normal pressure, safe and reliable, receive praises from customers.But because of its design feature, area of heat-supply service has been subjected to restriction.Mostly present horizontal boiler is bearing boiler, adopts subsidiary engines such as air blast, air-introduced machine, deduster, the cost height, and complicated operation, dangerous again.

The purpose of this utility model is: in order further to improve the needs of caloric value and expansion area of heat-supply service or central heating, adopt the heat pipe of former vertical boiler, technology such as spherical automatic wind exhaust have designed this heat pipe normal-pressure horizontal boiler.

The design feature of this heat pipe normal-pressure horizontal boiler is:

Body of heater (1), inner bag (2), adopt double-deck water pipe furnace grate (3), be provided with the two-layer water cavity smoke barrier (4) that interlocks relatively and have gradient before and after the combustion chamber of ground floor water pipe furnace grate, be provided with preface all around and arrange many of 4/5 vacuum heat-pipes (5), 1/8 of heat pipe is exposed at the combustion chamber, and 7/8 is immersed in the furnace chamber water; Be provided with heat pipe (5) around the combustion chamber of second layer water pipe furnace grate equally, the front upper place, combustion chamber is provided with the inclination water cavity smoke barrier (4) of below band water pipe, and smoke barrier and screw thread fire tube (6) are connected as a single entity.Fire, after cigarette passes through from the screw thread fire tube, upwards enter the interlaced cigarette grid (7) that boiler both sides and upper wall are provided with again, at the topmost of boiler spherical ventilation and dust removal device (8) is set, mouth (seeing accompanying drawing) is left on its top.

The design of this horizontal boiler is advanced upper and lower in boiler, the left and right serpentine of flue gas heat, has strengthened the stroke that heat passes through in stove, has prolonged circulation timei; Adopt the special heat conduction technology of 4/5 vacuum heat-pipe to carry out power conversion, and various heating device, enlarged boiler heating surface, improved the thermal efficiency of boiler significantly.

The effect of following thin, the last thick flue of this boiler design and the spherical ventilation and dust removal device at top, accelerated the flow velocity of air, made the boiler fuel combustion abundant, so this boiler does not need to install air blast, air-introduced machine by fire grate, save steel, fund, saves energy.

This boiler smoke from bottom to top, from left to right curve is circuitous advances, and the effect of the spherical ventilation and dust removal device at top, good dedusting effect has significantly reduced environmental pollution.

The heating system of this boiler is furnished with automatic pressure-reducing device, makes the operation of boiler normal pressure, and is safe and reliable, greatly reduces the rolled steel dosage of making boiler simultaneously, reduced the boiler cost significantly.

Description of drawings: Fig. 1 heat pipe normal-pressure horizontal boiler front view;

Fig. 2, heat pipe normal-pressure horizontal boiler right view.Among the figure 1, body of heater 2, inner bag 3, water pipe furnace grate 4, water cavity smoke barrier 5, vacuum heat-pipe 6, screw thread fire tube 7, cigarette grid 8, spherical ventilation and dust removal device.

Claims (2)

1, a kind of heat pipe normal-pressure horizontal boiler that is made of body of heater, inner bag, fire grate is characterized in that adopting double-deck water pipe furnace grate; Be provided with two-layer water pipe and the water cavity smoke barrier that interlocks relatively and have gradient before and after first combustion chamber, the place ahead, second combustion chamber is provided with one deck inclination water pipe and water cavity smoke barrier; Be equipped with many 4/5 vacuum heat-pipes that preface is arranged around two combustion chambers, 1/8 of heat pipe is exposed at the combustion chamber, and 7/8 is immersed in the furnace chamber water; The screw thread fire tube is equipped with in top, second combustion chamber; Staggered water cavity cigarette grid are set on top and the two side, and top structure is spherical ventilation and dust removal device.

2, heat pipe normal-pressure horizontal boiler as claimed in claim 1 is characterized in that boiler heating system is equipped with automatic pressure-reducing device, the operation of boiler normal pressure.
