Description

Automatic efficient three-purpose fuel boiler

The utility model relates to a kind of life oil burning boiler, and particularly a kind of full automatic high efficiency three of hot water, boiling water and steam that provides is used oil burning boiler.

At present, life has two kinds of steam boiler and hot-water boilers with oil burning boiler, and its medium volume space all only is one.Its weak point is: pressure-bearing medium volume space is generally all bigger, thereby the cost height of whole boiler, weight are also bigger, can not be installed on the roof; And water capacity is big, and steam supply, water speed are slow, and the energy consumption waste is bigger during to the few or non-rule steam supply of people, water; Do not adopt many backhauls burner hearth and flue, the waste heat loss is bigger; Do not adopt automatic oil burning apparatus, only have only the water supply self-con-tained unit, automaticity is not high.

The purpose of this utility model is exactly to provide a kind of to be installed on full automatic high efficiency three on the roof, efficient energy-saving, automatically continuous steam supply or boiling water or hot water and to use oil burning boiler at above-mentioned weak point.

Technical solution of the present utility model is: a kind of full automatic high efficiency three is used oil burning boiler, comprise pressure-bearing drum, water inlet, water outlet, steam supply control and conversion equipment, auto-supply temperature control oil burner, support and connection pipe and valve automatically, it is characterized in that: the pressure-bearing drum is fixed on the top of support, on support below the pressure-bearing drum, be provided with the pressure-bearing header of horizontal positioned, be provided with between this pressure-bearing drum and the pressure-bearing header and can constitute pressure-bearing fin tube combustion chamber and many backhauls flue, that be communicated with.Outside pressure-bearing header, pressure-bearing fin tube, pressure-bearing drum, also be provided with one with water feed apparatus with hold connection and hold the intercalated water sleeve that the pressure-bearing water pipe that connects under the case and valve are connected.Auto-supply temperature control oil burner is fixed on the combustion chamber and goes on the support at fire place.

Pressure-bearing header in the utility model technical solution can be ring-type, is fixed on the central plate of support.The pressure-bearing fin tube is welded between pressure-bearing drum and the pressure-bearing header.Auto-supply temperature control oil burner is upwards, and spray combustion shape is fixed on the center of central plate.

Pressure-bearing header in the utility model technical solution can also be distributed in pressure-bearing drum both sides and parallel straight tube for two.The pressure-bearing fin tube is welded between pressure-bearing drum and the pressure-bearing header.Auto-supply temperature control oil burner is level spray combustion shape and is fixed on the support of combustion chamber one side.

Pressure-bearing fin tube in the utility model technical solution is three circles, forms combustion chamber and three backhaul flues.

Pressure-bearing drum in the utility model technical solution can be the vertical type cylinder bodily form.

Pressure-bearing drum in the utility model technical solution can also be the horizontal cylinder bodily form.

The utility model is owing to be provided with pressure-bearing drum and two medium volume spaces of water jacket, pressure-bearing drum volume is less, thermal capacity is little, from cold water to the boiling water or the time that produces steam shorten greatly, temperature rise speed is fast, and is easy to control, be particularly suitable for the few or water of people, the erratic unit of vapour uses, avoided existing boiler no matter water, vapour what, all must water in the whole boiler is boiled, the power consumption waste is bigger.Owing to adopt less pressure-bearing drum, cost is reduced greatly, littler by 2/3rds than steam boiler cost, be particularly suitable for medium and small enterprises and institutions and use.Because whole cooker furnace volume is little, in light weight, can be fixed on the roof, neither takies the ground room area, again clean hygiene.Owing to adopt multi-return-stroke type combustion chamber and flue, the waste heat loss is reduced greatly, the thermal efficiency is up to more than 85%.Because adopt automatic water-supply, water level in the boiler automatic control and automatic oil burning apparatus, automaticity improves greatly, uses very convenient.The utility model can be supplied steam, boiling water and hot water, has avoided existing boiler can only supply the deficiency of steam or hot water.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the structural representation of the utility model embodiment 1; And as Figure of abstract;

Fig. 2 is the structure chart of facing of the utility model embodiment 2;

Fig. 3 is the side-looking structure chart of Fig. 2.

Below in conjunction with accompanying drawing the utility model embodiment is described in further detail:

Embodiment 1 as shown in Figure 1, support 3 can be fixed on the basis 1 on roof, is fixed with annular pressure-bearing header 4 on the support top, top is provided with pressure-bearing drum 6 again.Fix a upwards auto-supply temperature control oil burner 2 of spray combustion on the central plate of support 3, also be fixed with " clock " clevis layer water jacket 5 on the support 3.Three circle pressure-bearing fin tubes 9 are welded between pressure-bearing drum 6 and the ring-type pressure-bearing header 4, inner ring fin tube 9 surrounds fire box, inner ring, centre circle fin tube 9 constitute the first lap flue, centre circle fin tube 9 constitutes the second circle flue with water jacket 5 walls, be provided with the week seam between water jacket 5 and the pressure-bearing drum 6, from then on the gas of being convenient in the flue discharge.High-order autocontrol tank 7 is a little more than pressure-bearing drum 6.Water pipe is connected with valve 8 between high-order autocontrol tank 7, pressure-bearing drum 6, the water jacket 5.Pressure-bearing fin tube 9, ring-type pressure-bearing header 4, pressure-bearing drum 6 constitute the main heating surface of boiler, become an independently water capacity space, it also is the pressure-bearing part of this type boiler, also be fixed with " clock " clevis layer water jacket 5 outside it, cover in pressure-bearing part periphery, become another independently water capacity space, two water capacity spaces are when operation, a pressure-bearing, a pressure-bearing not, the two connects with pipeline valve.During for boiling water, when water temperature reaches 100 ℃, cut off burner 2 power supplys automatically, burn-out, simultaneously, magnetic valve is opened automatically for boiling water.The back supplementing water that supplies water is come in, and water temperature is lower than 100 ℃ again, burner 2 automatic starting ignition burnings.During for steam, when drum 6 internal pressures reached limit value, burner 2 quit work, and magnetic valve is opened for steam simultaneously, in case after vapour pressure is lower than limit value, burner 2 starting ignition burning again.During for steam, the water level height is by water level control and warning device control automatically in the drum, at this moment, the valve closing that pressure-bearing part water capacity space and water jacket 5 are got in touch, directly in drum 6, supply water with water pump, when water level meter water level was more or less than limit value on the drum 6, automaton cut out immediately or starts water pump and supplies water, and made drum 6 interior water levels remain ordinary water level.Water inlet, water outlet, steam supply are controlled automatically and conversion equipment can be realized automatic detection, control, demonstration and the warning of liquid level, pressure, temperature, supply water, the automatic conversion of vapour.

Embodiment 2 is as Fig. 2, shown in Figure 3, as different from Example 1: pressure-bearing drum 11 is the horizontal cylinder bodily form, and pressure-bearing header 15 is two straight tubes, is distributed in the both sides of drum 11, be fixed on the support 18, three layers of pressure-bearing fin tube 14 are fixed between drum 11 and the header 15.Water jacket 13 correspondences are located at the periphery of drum 11, fin tube 14, header 15.Burner 10 is fixed on the anterior furnace wall.Fire door 19 is located at burner 10 bottoms.Support 18 is fixed on the basis 17.Flue 12 is located at the top of drum 11.Identical among pipeline 16 and the embodiment 1.The course of work is also identical with embodiment 1.
