Abstract
The utility model provides a natural circulation low-temperature hot water boiler, comprising an independent integral boiler, heating up a water-cooling wall with the lowest temperature by the highest fire temperature and heating up a water-cooling wall with the highest temperature by flue gas with the lowest temperature at the end of a flue. The utility model is characterized in that a flue is formed by a plurality of boilers, a complete natural water circulation system is formed by a plurality of boiler and a drop water pipe, the water-cooling wall with the highest temperature is heated up by the highest fire temperature and the water-cooling wall with the lowest temperature is heated up by the flue gas with the lowest temperature. In a figure attached to the abstract: 1. Boiler water inlet; 2. Drop water pipe; 3. Boiler water outlet ; 4. Pipe loose joint; 5. Automatic vent valve; 6. Boiler horizontal pipe; 7. Furnace door; 8. Hearth; 9. Boiler butt to butt joint ; 10. Grate bar; 11. Chimney; 12. Boiler at the end of the chimney; 13. Boiler at the middle of the chimney. In the figure the boiler water inlet (1) is jointed butt to butt with a water down pipe of a radiator, the boiler water outlet (3) is jointed butt to butt with a water upflow pipe of the radiator, and the arrow shows the natural flow direction of water.
Description
The utility model relates to a kind of " tandem compound formula Natural Circulation low-temperature water heating power economized boiler ", energy-saving and environmental protection, reduction replacement cost.
Known civilian Natural Circulation low-temperature hot-water boiler generally all is horizontal and vertical two kinds at present, and delivery port is on the peak of boiler, and maximum water temperature is about in the of 85 ℃.Water inlet is gone into coolant-temperature gage generally below 30 ℃ at the lowest part of boiler, and boiler is with the minimum water-cooling wall of temperature in the highest fire temperature heating boiler at work.The water-cooling wall temperature is low excessively, influences the ignition temperature of stove hall, reduces the combustion rate of fuel.With the highest water-cooling wall of temperature in the minimum flue gas heating boiler of boiler outlet flue temperature, the having a narrow range of temperature of the terminal flue gas of water-cooling wall and flue, the coefficient of overall heat transmission is low, the exhaust gas temperature height.Particularly home-use boiler adopts spontaneous firing, and boiler volume is little, and above-mentioned shortcoming is excellent in outstanding.
The purpose of this utility model provides a kind of " tandem compound formula Natural Circulation low-temperature water heating power economized boiler ".Energy-saving and environmental protection, reduction replacement cost.
The purpose of this utility model is to realize like this, under the situation of not violating Natural Circulation low-temperature hot-water boiler operation principle, with the flue is the axle center, present known Natural Circulation low-temperature hot-water boiler rationally is divided into a plurality of boiler tandem compounds becomes a flue, a plurality of boilers are connected into a complete natural water circulation system with down-flow pipe.The water at low temperature that loops back from radiator enters the water inlet of flue least significant end boiler, the water at low temperature that loops back from radiator with the low-temperature flue gas preheating of flue least significant end boiler, enter the water inlet of second boiler of flue least significant end again by down-comer through the water at low temperature of heating, finally enter the water inlet of stove hall boiler with the water at low temperature of this form heating, there is the delivery port of stove hall boiler to dock with the upper hose of radiator, when work with boiler in the minimum flue-gas temperature heating water circulating system the minimum water-cooling wall of temperature (temperature difference is big, coefficient of overall heat transmission height, exhaust gas temperature is low).(water-cooling wall temperature height improves burning condition, and the combustion rate of fuel improves with temperature is the highest in the fiery temperature heating water circulating system of maximum temperature water-cooling wall.)。Boiler the easiest damage be exactly stove hall part, and the stove hall of this boiler partly is an independent boiler, changes easily, reduces replacement cost.
Owing to adopted such scheme, through practice, boiler combustion position at work is good, and firing rate reduces, and leaving water temperature increases, and has only adopted tandem compound.
Below in conjunction with accompanying drawing the utility model is further specified.
Figure of description (Fig. 1) is the horizontal sectional structural map of looking of the utility model tandem compound formula Natural Circulation water power economized boiler, is to overlook sectional structural map (Fig. 2).
In the Figure of description: 1, the down-flow pipe 13, flue middle-end boiler 14, the flue end boiler that are connected with stove hall boiler of the down-flow pipe 3, boiler delivery port 4, pipe loose joint 5, automatic exhaust steam valve 6, boiler horizontal water tube 7, fire door 8, stove hall 9, boiler docking port 10, fire bars 11, chimney 12, the flue middle-end boiler that are connected with flue middle-end boiler of the terminal boiler of boiler water inlet 2, flue
Boiler feed water mouth (1) docks with the downcomer of radiator in the drawings, and boiler delivery port (3) docks with the upper hose of radiator, the natural flow direction of arrow (↓) expression water.
Claims (1)
1, a kind of Natural Circulation low-temperature hot-water boiler, its existing structure is a whole boiler, water inlet pipe mouth is at the bottommost of boiler, effluent pipe mouth is on the peak of boiler, it is characterized in that: become a flue by a plurality of Natural Circulation low-temperature hot-water boiler tandem compounds, with down-flow pipe each two adjacent Natural Circulation low-temperature hot-water boiler is connected, water inlet pipe mouth is in the bottom of the terminal boiler of flue, and effluent pipe mouth is on the peak of flue top boiler.
