Measure control unit 571 be oriented to boiler body 51 boiler water flow, relative to from heat storage unit 59 via compressed air heat exchanger
56 are oriented to the ratio of the flow of the boiler water in flow control portion 571.
When reflux ratio is 100%, whole boiler waters that flow control portion 571 is oriented to from compressed air heat exchanger 56 are logical
Inflow-rate of water turbine control unit 571 simultaneously returns to boiler body 51.On the other hand, it when reflux ratio is less than 100%, is handed over from Heat of Compressed Air
It is multiplied by the boiler water of the ratio for being equivalent to longitudinal axis value and the flow calculated on the flow for the boiler water that parallel operation 56 is sent out, passes through flow
Control unit 571 returns to boiler body 51.In addition, remaining boiler water is directed to branch piping 523 using flow control portion 571,
After converging with the boiler water sent out from boiler body 51 in fluidic junction 52b, the second pump is directed to via second circulation channel 522
55。
In the figure 2 example, for temperature difference Δ t in 0 or more t1 or less, reflux ratio is 100%, comes from Heat of Compressed Air
Whole boiler waters of exchanger 56 return to boiler body 51.Thus, it is possible to be swept what is recycled in compressed air heat exchanger 56
Heating (or keep temperature) of the waste heat of gas efficient for the boiler water in boiler body 51.
On the other hand, when temperature difference Δ t is more than t1, reflux ratio is less than 100%, comes from compressed air heat exchanger 56
The part of boiler water return to boiler body 51, remaining boiler water is piped not by boiler body 51 via branch
523 return to the second pump 55.When above-mentioned temperature difference Δ t is more than t1 and in t2 or less, as temperature difference Δ t increases, utilizes flow
The control of control unit 571 makes reflux ratio be gradually reduced.In other words, as temperature difference Δ t becomes larger, flow control portion is utilized
571 control, the flow that the boiler water of boiler body 51 is oriented to from heat storage unit 59 are gradually reduced.In addition, when temperature difference Δ t is in t2
When above, reflux ratio is greater than 0% and the fixed regulated proportion less than 100%.
As described above, in heat storage unit 59, reduced using the temperature of boiler water when boiler water heat storage material.From boiler
When the temperature of water subtracts the temperature difference Δ t that the temperature of heat-storing material obtains and becomes larger, the temperature of the boiler water in heat storage unit 59 reduces
It also becomes larger.Therefore, when temperature difference Δ t is larger, if whole boiler waters that temperature reduces in heat storage unit 59 return to boiler master
Body 51, then the temperature of the boiler water in boiler body 51 may be less than set point of temperature range, can be to boiler body 51 into ship
Steam supply belt carry out baneful influence.
