CN2795735Y - Oil buring water heating stove - Google Patents

Abstract

The utility model discloses an oil burning water heating stove, including a water tank, a burner and a fuel tank. A heat exchange box is arranged in the water tank. A plurality of rows of water pipes are horizontally or slantingly distributed in the heat exchange box and the water in the water pipes is all connected with the water in the water tank out of the heat exchange box. There is a smoke outlet at the top of the heat exchange box, and the burner is installed below the heat exchange box. When the water in the water tank of the utility model makes heat exchange, first, the heat exchange box and the water outside the heat exchange box makes cold and heat exchange at the same layer, and then the water outside the heat exchange box makes cold and heat exchange in the different layers, which makes the water temperature in entire water tank rises relatively uniformly. The maximum temperature of the smoke outlet is only 180 DEG C, the water in the upper part and the lower part in the water tank substantially reaches boiling temperature at the same time. Therefore, water heating speed is fast and energy-saving effect is very obvious.

Description

The fuel oil boiler

Technical field

The utility model relates to a kind of fuel oil boiler.

Background technology

The vertical oil burning boiler of the general employing of known boiler, this boiler is made up of combustor, burner hearth and water tank, and straight fire tube vertically is housed in the water tank, the fire tube bottom is connected with burner hearth, top links to each other with chimney, and fire tube is outward a water, passes to by the heat of fire tube to add hot water in the water.Because adopting fire tube heating and fire tube vertically arranges, water in the water tank in heating process up and down water directly carry out cold and hot exchange, chimney is to the draft effect of fire tube in addition, fire tube is very high near the temperature of chimney one end, and generally between 420 ℃-500 ℃, making up and down, the temperature of water differs increasing, usually after the water above has seethed with excitement seven or eight minutes, following water just arrives boiling temperature, and the time of heating up water is long, and consumes energy is many.With 1 ton of boiler is example, if 60 a minutes boiled stove water must gas-distributing motor power be 550W, oil consumption is the combustor of 4.5L per hour.

The utility model content

The purpose of this utility model is to provide that a kind of speed of heating up water is fast, the significant boiler of energy savings.

The utility model comprises a water tank, a combustor, a fuel tank, also has a heat exchange box in the water tank, be furnished with plurality of rows water pipe that put or that tiltedly put for sleeping in this heat exchange box, the water of described water pipe all leads to the water of heat exchange box outer water tank, outlet flue is arranged at the heat exchange box top, combustor be installed in heat exchange box below.

Owing to be provided with heat exchange box in the water tank of the present utility model, and what be provided with in the heat exchange box is many water pipes, when the combustor heat exchanging case below the heat exchange box heats, be heated at first and heating temperature is the highest is the water pipe of heat exchange box bottom, more up heating temperature is low more, can only carry out cold and hot exchange with the outer cold water of water pipe at first after the water heating in every layer of water pipe with layer, therefore the water in the water tank is when carrying out heat exchange, the water of heat exchange box and its outside was carrying out cold and hot exchange with aspect before this, the water that is the heat exchange box outside then carries out cold and hot exchange in different aspects, make the coolant-temperature gage in the whole water tank rise more even, the maximum temperature of outlet flue has only 180 ℃, the water of water tank internal upper part and bottom reaches boiling temperature basically simultaneously, is example with the utility model of 1 ton of capacity, 60 a minutes boiled stove water, only needing to adopt power is 90W, per hour factor is the oil-burning machine of 2L, compares with traditional boiler, of the present utility model energy-conservation (, oil) effect is very obvious.

The specific embodiment

Fig. 1 to Fig. 3 has reflected the concrete structure of embodiment one, the utlity model has the water tank 1 of a band heat-insulation layer, combustor 2, a fuel tank 3 as can be seen from Fig. 1 and Fig. 2.The heat exchange box 4 that one rectangle column is arranged in the water tank, several rows of tilting water pipe 5 is arranged in the heat exchange box 4, water pipe hole 6 by the heat exchange box two side is connected across between the heat exchange box two side, the exterior of the two-port of all water pipes and heat exchange box 4 makes the water in the water tank 1 carry out cold and hot exchange with the water in the water pipe 5.Be base 11 below the heat exchange box 4, combustor 2 is installed in base 11 central authorities, and outlet flue 7 is biased in the top of heat exchange box 4, and heat-energy losses can be littler when discharging fume like this.Water inlet pipe 8 is arranged at the top of water tank 1, and there is an overflow pipe 9 side, and the bottom of water tank 1 is provided with outlet pipe 10.Fig. 3 has reflected the oil circuit and the circuit of the utility model combustor, its fuel tank 3 adopts the voltage stabilizing fuel tank, by conduit through oil circuit breaker 12, oil filter 13, pressure maintaining valve 14, magnetic valve 15, wind oil interlock valve 16 to combustor 2, among the figure as can be seen the part that need switch on of the utility model have: blower fan in the combustor 2 and spark plug, magnetic valve 15, they link to each other with power supply by blower fan button 17, button ignition switch 18 and magnetic valve button 19 respectively.Open oil circuit switch 12 during use earlier, press blower fan button 17 then, the blower fan in the combustor 2 gets and begins after electric to rotate, and then presses button ignition switch 18, press magnetic valve button 19 again, magnetic valve 15 adhesives, the oil circuit conducting, oil is atomized, lights, burns after entering combustor 2, regulate wind oil interlock control valve this moment, make wind oil proportioning reach optimum state, disposable mixing up need not be transferred later on again.

Embodiment two:

Embodiment two is roughly the same with the structure of embodiment one, mainly on heat exchange box 4, Fig. 4 and Fig. 5 have reflected the heat exchange box shape of embodiment two in the difference of the two, and its profile is snakelike, inner water pipe 5 is in tilted layout, and adjacent row's water pipe incline direction is opposite.The energy-saving effect of present embodiment than embodiment one also significantly, it at first is the layout of its water pipe, because adjacent row's water pipe incline direction is opposite, hot water all can move to high-end in every drainpipe, because the low side of last drainpipe is an aspect with the high-end of following drainpipe, every layer of water pipe and the outer cold and hot exchange velocity of water pipe have been accelerated thus; Moreover be that the employing of heat exchange box profile is snakelike, be subjected to damping when making in the water tank up and down water carry out cold and hot exchange, causing up and down, the temperature difference of water further reduces, as there being a conveyor screw in water tank, constantly to stir, water tank water up and down almost can reach boiling temperature simultaneously, thereby hot water speed is faster, and the effect of energy savings is more obvious.
