A waterline system is used for setting up water circulation channel to boiler 12, heat collector 24, secondary water tank 46 supply cold water between boiler 12 and heat collector 24 and secondary water tank 46, and output hot water.Introduce the waterline system in detail below with reference to Fig. 4.Cold water source (for example running water pipe) is connecting first port of three-way connection T3 by the cold water inlet pipe line 68 that has check valve 88, stop valve V3.Second port of three-way connection T3 connecting the water inlet pipe 26 of heat collector 24; The 3rd port of three-way connection T3 connecting pipeline 80.Pipeline 80 is connecting first port of three-way connection T2.Second port of three-way connection T2 connecting the water inlet 32 of boiler 12 by pipeline 72; The 3rd port of three-way connection T2 connecting the water in-out port 50 of secondary water tank 46 by the pipeline 82 that has stop valve V5.In addition, the outlet pipe 28 of heat collector 24 is being connected first port of three-way connection T4 with pipeline 98 through elbow 86.Second port of three-way connection T4 connecting the delivery port 34 of boiler 12 by pipeline 74; The 3rd port of three-way connection T4 connecting the water inlet 48 of secondary water tank 46 by pipeline 84.In addition, the pipeline 92 that has a stop valve V4 is connecting first delivery port 40 of secondary water tank 46.In addition, pipeline 94 is connected between first port of second delivery port 42 of secondary water tank 46 and three-way connection T1.Second port of three-way connection T1 is connecting the hot water delivery pipe's line 70 that has stop valve V1; The 3rd port of three-way connection T1 is connecting the pipeline 76 that has stop valve V2, and pipeline 76 leads to a row pressure glass container 78 that opens wide towards atmosphere, and this row pressure glass container 78 has peak level index line 96.Under stop valve V1, V4 closing state, if be full of water in the secondary water tank 46 and continue water filling in secondary water tank 46, the water in the then secondary water tank 46 can flow in the row pressure glass container 78 and arrive peak level index line 96.Therefore, arrive peak level index line 96, can learn in the secondary water tank 46 to be full of water by observing the water surface.Perhaps, if the water in the secondary water tank 46 reaches fluidized state, steam can be discharged by row pressure glass container 78, thereby can learn this fluidized state.
By the waterline system, secondary water tank 46 is communicated with boiler 12, heat collector 24 respectively, and can realize in the secondary water tank 46 water respectively with boiler 12, heat collector 24 in the circulation of water.In this, the circulation that it is pointed out that water is flow phenomenon is realized by hot and cold water.For this reason, need make the first half of secondary water tank 46 be higher than boiler 12 and heat collector 24.Because the pressure in the latter half of secondary water tank 46 is roughly suitable with the pressure in boiler 12 and the heat collector 24, and the pressure in the first half of secondary water tank 46 is higher than the pressure in the part of its underpart, and therefore the pressure in the first half of secondary water tank 46 also just is higher than the pressure in boiler 12 and the heat collector 24.By this pressure reduction, can realize water in the secondary water tank 46 and the circulation between the water in boiler 12 and the heat collector 24.
Introduce the operation of waterline system below.
(1) adds water state.When first the use, before firing, all be empty in boiler 12, heat collector 24, the secondary water tank 46 at this moment.At this moment, close stop valve V1 and V4, open stop valve V2, V3 and V5, make cold water enter three-way connection T3 by pipeline 68 by check valve 88.One cold water by three-way connection T3 output enters heat collector 24 through water inlet pipe 26, and can enter secondary water tank 46 by outlet pipe 28, pipeline 98 and pipeline 84 after being full of heat collector 24; Another strand cold water by three-way connection T3 output enters three-way connection T2.One cold water by three-way connection T2 output enters secondary water tank 46 through pipeline 82; Another strand cold water by three-way connection T2 output enters boiler 12 through pipeline 72, and enters secondary water tank 46 by pipeline 74 and 84 after being full of boiler 12.Along with further water supply, secondary water tank 46 finally is filled water.At this moment, because stop valve V1 closes, therefore, water will flow in the row pressure glass container 78 after being full of secondary water tank 46, after seeing that the water surface arrives peak level index line 96, can close stop valve V3, to stop water supply.If the water surface has exceeded peak level index line 96, can open stop valve V4 and bleed off unnecessary water.
(2) static heating.Next, utilize the net 36 of igniting to fire, make the fuel in the combustion chamber reach the normal combustion state.At this moment, because boiler 12 and heat collector 24 are heated, therefore can form the hot and cold water convection current with secondary water tank 46 at boiler 12 and heat collector 24.According to the hot and cold water convection properties, the cold water of secondary water tank 46 bottoms flows out from water in-out port 50, and enter the bottom of boiler 12 by water inlet 32 through pipeline 82 and pipeline 72, cold water is heated in boiler 12 and rises, hot water is flowed out by delivery port 34, and is entered in the secondary water tank 46 by water inlet 48 through pipeline 74 and 84.Like this, between boiler 12 and secondary water tank 46, formed continuous circulation.Similarly, the cold water of secondary water tank 46 bottoms flows out from water in-out port 50, and is entered the annular cavity 90 of heat collector 24 by water inlet 10 through pipeline 82, pipeline 80 and water inlet pipe 26.Warmed-up water flows out from delivery port 8 in annular cavity 90, and is entered in the secondary water tank 46 by water inlet 48 through outlet pipe 28, pipeline 98 and pipeline 84.Like this, between heat collector 24 and secondary water tank 46, formed continuous circulation.
By above-mentioned two circulations continuously, the water temperature in the secondary water tank 46 continues to raise, until finally being heated to fluidized state.The steam that boiling produces in the secondary water tank 46 can be discharged by row pressure glass container 78.Like this, can in secondary water tank 46, accumulate hot water even boiling water.In office what is the need for when wanting water can be opened stop valve V1 or V4 and hot water or boiling water in the secondary water tank 46 are emitted.Afterwards, can open stop valve V3, so that once more with topped up with water in the secondary water tank 46.
(3) dynamic heat.When needs use hot water continuously in a large number (for example having a bath), close stop valve V2, V4 and V5, open stop valve V1 and V3.Like this, import by pipeline 68 from the cold water of cold water source, and enter boiler 12 and heat collector 24 by pipeline 72 and water inlet pipe 26 respectively.Heated water converges in the pipeline 84 by pipeline 74 and outlet pipe 28, and is entered the secondary water tank 46 by water inlet 48 from pipeline 84.Hot water in the secondary water tank 46 is by pipeline 70 outputs, for continuous use.
Burner of the present invention can be operated under three kinds of mode of operations, introduces them below in detail.
First kind of mode of operation is the pattern of smouldering.When not needing to utilize burner heating and cooking appliance or heat collector 24,, take this pattern for example at night.At this moment, slag-drip opening and air outlet 52 are all closed (aperture is zero), and air blast does not start, and only supply air by the slit of air outlet and slag-drip opening to the combustion chamber, thereby fuel combustion speed is the slowest, and firepower is the most weak, so that burner is in (the protecting fire) state of smouldering.In this, it may be noted that iff can not guarantee to keep the not flame-out necessary lowest empty tolerance of fuel by described slit to be supplied to the combustion chamber, that is to say, fuel may extinguish because of lacking oxygen, then air outlet and/or slag-drip opening can be opened a little slit.The burning result of based on fuel accumulates experience, and user oneself can determine the size in slit.Under the pattern of smouldering, the temperature maintenance of combustion chamber is more than 100 ℃, and the smoldering time was 10 hours.Even under the pattern of smouldering, also can heat the water in the secondary water tank by boiler (also can add heat collector).Under the pattern of smouldering,, the water temperature in the secondary water tank 46 is reached about 80～90 ℃ through after 3～5 hours.After through 7～10 hours, can make water temperature in the secondary water tank 46 near 100 ℃.
Second kind of mode of operation is the moderate heat pattern.When needs provide medium firepower, when for example cooking, air outlet and slag-drip opening can be opened at utmost (aperture maximum), thereby provide air to the combustion chamber in the mode of natural air inlet.If the user feels firepower deficiency is arranged slightly, also slag-drip opening can be closed (aperture be zero),, and air outlet is adjusted to satisfied aperture blower opening.In the above two kinds of cases, all with medium speed's burning, so that medium firepower to be provided, the temperature of combustion chamber is more than 300 ℃ to fuel.Therefore, this mode of operation can be called the moderate heat pattern.This pattern is suitable for the general cooking in family uses.Can use heat collector 24 this moment, so that utilize heat collector 24 and 12 pairs of water of boiler to heat.Perhaps, also can not use heat collector 24, so that only utilize 12 pairs of water of boiler to heat.Anyway, under the moderate heat pattern, can utilize secondary water tank 46 stored hot waters even boiling water.Convection current running by hot and cold water, the water in the secondary water tank 46 even can be by boiled.
The third mode of operation is a heating mode rapidly.When needs provide big firepower, when for example having a bath for the people, heat collector 24 is placed the body of heater top, slag-drip opening is closed (aperture be zero),, and air outlet is adjusted to maximum opening blower opening, so that fuel burns with maximal rate, therefore and maximum fire is provided, and the temperature in this moment combustion chamber can be elevated to more than 1300 ℃, thus fast supply hot water continuously.This pattern is suitable for having a bath etc. in family uses, so that a large amount of hot water or boiling water to be provided.Perhaps, can in the hotel, be used for the large batch of cooking.
Since the volume of boiler only be secondary water tank volume about 1/25, therefore under the pattern of smouldering, cause the furnace body temperature reduction thereby boiler can not absorb too many heat from body of heater.In addition, owing to boiler is located at around the upper of furnace body, so the reduction of boiler temperature can not cause too big influence to the fuel that mainly concentrates on the middle and lower part, combustion chamber.Simultaneously, if the water temperature in the boiler drops to a certain degree, then only heat collector is heated, and only by heat collector by water to flowing to secondary water tank supply heat, conversely, secondary water tank is supplied heat by the convection current of water to boiler again.Like this, but the water temperature in the maintaining heat water tank can not drop to low degree, and is too many to keep the unlikely reduction of furnace body temperature, thereby prevents that fuel from extinguishing.
Burner according to the present invention has multiple advantages. At first, it can be used in family Or in the hotel. Secondly, it can provide multiple output, comprising with different The intensity quantity of heat given up is to implement heating, with different speed and temperature output hot water etc. In addition. It can use multiple different solid fuel. In addition, coal is being used as fuel The time, can have low cost, can replace thus make electricity consumption, coal gas, liquefied petroleum gas, The stove and accessory of natural gas etc.
