The vertical efficient less boiler

The utility model relates to a kind of vertical efficient less boiler, is mainly used in to add hot water.

Existing vertical boiler has only a flue, and its weak point is: coal combustion is insufficient, and the thermal efficiency is low.

The purpose of this utility model is to overcome above-mentioned weak point of the prior art and provides a kind of thermal efficiency high many courages vertical efficient less boiler.

The purpose of this utility model can reach by following measure: the utility model is by furnace bottom, furnace roof, Pressure gauge, safety valve, thermometer, body of heater, burner hearth, second, three, four heating chambers and first, two, three, four flues are formed, burner hearth is arranged in the body of heater from bottom to up, second, three, four heating chambers, there is short bile duct to be communicated with between burner hearth and second heating chamber and each heating chamber, first flue is arranged at burner hearth periphery and top, second, second flue is arranged between three heating chambers, the 3rd, the 3rd flue is arranged between four heating chambers, long bile duct and the 4th flue are arranged on the 4th heating chamber.

The drawing of accompanying drawing is described as follows:

Fig. 1 always schemes for vertical section of the present utility model;

Fig. 2 is the A-A profile of Fig. 1;

Fig. 3 is the B-B profile of Fig. 1;

Fig. 4 is the C-C profile of Fig. 1.

13, long bile duct 14, water for bathing outlet 15, Pressure gauge 16, safety valve

17, impact tube 18, furnace roof 19, thermometer 20, heat release water pipe

21, lack bile duct 22, coal filling hole 23, non-dirty mouthful 24, draw cinder notch

25, stone or metal plate for standing a stove on as a precaution against fire 26, water supply tank 27, second heating chamber 28, the 3rd heating chamber

29, the 4th heating chamber.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing: Fig. 1 represents that vertical section of the present utility model always schemes, water supply tank 26 should place the top of boiler, represent with dotted line with the communicating pipe of water supplement port 2, for avoiding referring to the crossing folding line that is divided into of line with piece number.Cylindrical furnace is welded with furnace bottom 1 12 times, on be welded with the band impact tube 17 furnace roof 18.Furnace bottom is drawn cinder notch 24, cylindrical burner hearth 3 is arranged on the furnace bottom, burner hearth has coal filling hole 22, with roof of the furnace first flue 5 is arranged between burner hearth and body of heater, the stone or metal plate for standing a stove on as a precaution against fire 25 under the burner hearth burns in the coal adding burner hearth, temperature is the highest in the burner hearth, the heating water out 4 that the first flue upside has the highest heating gas of temperature to use, the water temperature of outflow can reach more than 80 ℃, and downside has water supplement port 2 and sewage draining exit 23 respectively.Burner hearth is main heating chamber, also can be referred to as first heating chamber, and there is second heating chamber 27 the burner hearth top, has short bile duct 21 to be communicated with therebetween.Second heating chamber is a patty, and the periphery is exactly a body of heater, has inspection opening 6, checking the fired state in this chamber, for heating chamber thereafter will be denied oxygenation and add how much oxygen foundation is provided.The top of second heating chamber also can be provided with one to a plurality of heating chambers, present embodiment is two i.e. third and fourth heating chambers 28 and 29, this two chamber is the external diameter patty little than second heating chamber, all there is short bile duct to be communicated with between second, third and the 4th heating chamber, each of present embodiment layer short bile duct 21 is four, the short bile duct of each layer all by the 45 ° of layouts that stagger referring to Fig. 2 and Fig. 3, be beneficial to cause the thermal current of turbulent flow, thereby improve heat exchange efficiency.The 3rd heating chamber and the 4th heating chamber are provided with oxygenating hole 9, are communicated with source of oxygen by pipeline, are being provided with pipe valve (not expressing on the figure) near on the oxygen channel of body of heater, with switch and adjusting amount of oxygen.Between second heating chamber and the 3rd heating chamber second flue, 8, the second heating chamber heat in the exterior water outs 7.It between the 3rd heating chamber and the 4th heating chamber the 3rd flue 10.The 4th heating chamber top has long bile duct 13 to be communicated with furnace roof 18 inner chambers, and the long bile duct of present embodiment is that internal layer is seen Fig. 4 with each four of the skins and the 45 ° of layouts that stagger mutually, is water-filled the 4th flue 11 around the long bile duct.Coal-fired at burner hearth internal combustion and the heat that fully burns and produced through oxygenating, priority is through the heat transfer process of first to fourth flue, the temperature of hot gas is very low, if temperature is still high, can also above the 4th heating chamber, be communicated with the 5th or more heating chambers again, to maximally utilise heat energy, to scatter and disappear inevitably except that the bottom the small amount of thermal energy in body of heater inside, remaining heat energy is all utilized to greatest extent, so the thermal efficiency of the present utility model is very high.Because oxygenating is abundant, it is very abundant to burn, so smokeless the discharge.The 4th flue is connected to heat release water pipe 20, and thermometer 19, water for bathing outlet 14, Pressure gauge 15 and safety valve 16 are equipped with in the top.

The utility model contrast prior art has following advantage:

Coal combustion is abundant, thermal efficiency height; Save coal-fired; Environmental pollution is little.
