In boiler plant 5, by driving the second pump 55, aqueous boiler water is sent from boiler body 51 to the second circulation canal 522.The boiler water sent from boiler body 51 as shown by the arrows in Figure 1, via the second circulation canal 522 successively by the second pump 55, heat storage unit 59, switching part 572, compressed air heat exchanger 56 and flow-control portion 571, circulates to boiler body 51.
Heat storage unit 59 has heat-storing material.In heat storage unit 59, between heat-storing material and the boiler water flowing through the second circulation canal 522, carry out heat exchange.Such as, when the output of prime mover 3 is more than conventional output (CSO:Continuous Service Output), because the temperature of the boiler water sent from boiler body 51 is higher, so the temperature of heat-storing material is lower than the temperature of boiler water flowing through the second circulation canal 522 in heat storage unit 59.So, when the temperature of heat-storing material lower than when flowing through the boiler water of the second circulation canal 522 in heat storage unit 59, heat-storing material is heated by boiler water, in heat storage unit 59, carry out accumulation of heat.The temperature of the heat-storing material in heat storage unit 59 is measured by the second determination part 582.
In heat storage unit 59, boiler water is cooled by heat-storing material.The boiler water sent from heat storage unit 59 is directed to switching part 572.Switching part 572 is such as the triple valve that the second circulation canal 522 is arranged.The second circulation canal 522 is utilized to be directed to compressed air heat exchanger 56 by the boiler water after switching part 572.In switching part 572, shunt pipe arrangement 525 shown in dotted lines in Figure 1 is from the second circulation canal 522 shunt, and the fluidic junction 52c place between compressed air heat exchanger 56 and flow-control portion 571, converge with the second circulation canal 522.Pipe arrangement 525 along separate routes is not used in accumulation of heat pattern." heat supply mode " of pipe arrangement 525 is along separate routes used to will be explained below.100 ~ 130 DEG C are such as about from switching part 572 towards the temperature of the boiler water of compressed air heat exchanger 56.
The boiler body 51 that compressed air heat exchanger 56 is configured in from heat storage unit 59 to boiler portion 50 on the second circulation canal 522 guides the pipe arrangement of boiler water.Specifically, compressed air heat exchanger 56 is configured between heat storage unit 59 and flow-control portion 571 on the second circulation canal 522.In addition, compressed air heat exchanger 56 is configured on the scavenge trunk 31 between compressor 42 and prime mover 3.Compressed air heat exchanger 56 using from compressor 42 to the scavenging in the scavenge trunk 31 that prime mover 3 supplies as thermal source, heating flows through the aqueous boiler water of the second circulation canal 522.In other words, in compressed air heat exchanger 56, using the used heat of prime mover 2 of band booster contained in scavenging as heat source boiler water.
Send aqueous boiler water from compressed air heat exchanger 56, or send the fluid-mixing of gasiform boiler water and aqueous boiler water.Boiler body 51 is returned by the boiler water heated by flow-control portion 571 in compressed air heat exchanger 56.Changed according to the output of prime mover 3 and the temperature of surrounding etc. by the temperature of the scavenging of compressed air heat exchanger 56.Described scavenging temperature when the output of prime mover 3 is maximum output (100% exports) is such as about 220 DEG C.When the output of prime mover 3 reduces, scavenging temperature also reduces.From the temperature of the boiler water that compressed air heat exchanger 56 is sent, because flowing into the temperature of the boiler water of compressed air heat exchanger 56 and being changed by the temperature of the scavenging of compressed air heat exchanger 56 etc.The temperature flowing to the boiler water in flow-control portion 571 from compressed air heat exchanger 56 is such as about 135 ~ 165 DEG C.
Flow-control portion 571 is arranged on the triple valve on the second circulation canal 522.In flow-control portion 571, from the second circulation canal 522 along separate routes, and fluidic junction 52b place between boiler body 51 and the second pump 55 and the second circulation canal 522 converge shunt pipe arrangement 523 as shown in phantom in Figure 1.
In boiler plant 5 as mentioned above, utilize the first determination part 581 to measure the temperature of the boiler water in boiler body 51, utilize the second determination part 582 to measure the temperature of the heat-storing material of heat storage unit 59.The temperature difference obtaining section 573 that first determination part 581 measured value respective with the second determination part 582 is connected in flow-control portion 571 sends.In temperature difference obtaining section 573, according to the measured value from the first determination part 581 and the second determination part 582, the temperature of the heat-storing material deducted in heat storage unit 59 from the temperature of the boiler water the boiler body 51 in boiler portion 50 obtains temperature difference.And, according to described temperature difference, utilize flow-control portion 571 to control the flow of the boiler water guided to the boiler body 51 in boiler portion 50 via compressed air heat exchanger 56 from heat storage unit 59.
Fig. 2 is the figure of an example of the flow-control of the 571 pairs of boiler waters in flow-control portion.The transverse axis of Fig. 2 represents the temperature difference Δ t of boiler water and the heat-storing material obtained by temperature difference obtaining section 573.The longitudinal axis of Fig. 2 represents the boiler water guided from compressed air heat exchanger 56 to flow-control portion 571, by returning the ratio (hereinafter referred to as " backflow ratio ") of the boiler water of boiler body 51 behind flow-control portion 571.In other words, backflow ratio is the flow of boiler water of boiler body 51 of leading via compressed air heat exchanger 56 and flow-control portion 571 from heat storage unit 59, relative to the ratio of flow of boiler water of the flow control part 571 that leads via compressed air heat exchanger 56 from heat storage unit 59.
When backflow ratio is 100%, return boiler body 51 from lead whole boiler waters of flow control part 571 of compressed air heat exchanger 56 by flow-control portion 571.On the other hand, when backflow ratio is less than 100%, is multiplied by the boiler water of the ratio being equivalent to longitudinal axis value and the flow calculated at the flow of the boiler water sent from compressed air heat exchanger 56, returns boiler body 51 by flow-control portion 571.In addition, remaining boiler water utilizes flow-control portion 571 to be directed to pipe arrangement 523 along separate routes, after converging, is directed to the second pump 55 via the second circulation canal 522 with the boiler water sent from boiler body 51 in fluidic junction 52b.
In the figure 2 example, temperature difference Δ t is more than 0 during below t1, and backflow ratio is 100%, and the whole boiler waters from compressed air heat exchanger 56 return boiler body 51.Thus, can the heating (or keep temperature) of the used heat of the scavenging of reclaiming in compressed air heat exchanger 56 efficient for the boiler water in boiler body 51.
On the other hand, when temperature difference Δ t is greater than t1, backflow ratio is less than 100%, and the part from the boiler water of compressed air heat exchanger 56 returns boiler body 51, remaining boiler water not by boiler body 51, but returns the second pump 55 via shunt pipe arrangement 523.When said temperature difference Δ t be greater than t1 and at below t2 time, along with temperature difference Δ t increases, utilize the control in flow-control portion 571 that backflow ratio is reduced gradually.In other words, along with temperature difference Δ t becomes large, utilize the control in flow-control portion 571, reduce gradually from the lead flow of boiler water of boiler body 51 of heat storage unit 59.In addition, when temperature difference Δ t is at more than t2, backflow ratio be greater than 0% and be less than 100% fixing regulation ratio.
As mentioned above, in heat storage unit 59, the temperature of boiler water during boiler water heat storage material is utilized to reduce.When the temperature difference Δ t that the temperature deducting heat-storing material from the temperature of boiler water obtains becomes large, the temperature of the boiler water in heat storage unit 59 reduces and also becomes large.Therefore, when temperature difference Δ t is larger, if whole boiler waters that temperature reduces in heat storage unit 59 return boiler body 51, then the temperature of the boiler water in boiler body 51 may, lower than set point of temperature scope, bring baneful influence to the steam supply in ship can to boiler body 51.
Therefore, the steam generator system 1 shown in Fig. 1, when above-mentioned temperature difference Δ t is larger, by reducing the flow of the boiler water returning boiler body 51 from heat storage unit 59, can suppress or prevent the temperature of the boiler water in boiler body 51 lower than set point of temperature.Its result, can supply the steam of temperature required boiler water to the vapour system in ship.In addition, reducing the flow of the boiler water returning boiler body 51 from heat storage unit 59 gradually by increasing along with temperature difference Δ t, can suppress or prevent the temperature of the boiler water in boiler body 51 lower than set point of temperature further.That is, flow-control portion 571 is temperature control parts of the temperature of the boiler water controlled in the boiler body 51 in boiler portion 50.
In addition, in steam generator system 1, the temperature of the boiler water at position beyond the boiler body 51 that the first determination part 581 also can be utilized to measure in boiler portion 50, and according to the temperature difference that the temperature that the temperature from described boiler water deducts heat-storing material obtains, and the above-mentioned flow-control utilizing flow-control portion 571 to carry out boiler water equally.Now, also can suppress or prevent the temperature of the boiler water in boiler body 51 lower than set point of temperature.
