Heating part 3 has the warm bath facility 32 stockpiling warm water, and the warm water of warm bath facility 32 is supplied to the pump 33 of bypass heat exchanger 20 and coagulator 26.In addition, heating part 3 has cooling tower 34, at the upstream side of coagulator 26, adds the cooling water supplied from cooling tower 34 to the warm water supplied from warm bath facility 32, in the downstream side of coagulator 26, the warm water with amount is imported cooling tower 34.In order to not make the water degradation of warm bath facility 32, cooling tower 34 preferably uses the water-cooled of sealed mode or the cooling tower of air cooling.
In addition, the water of condensation of the warm water and circulating water of delivering to bypass heat exchanger 20 is carried out heat exchange and is heated, and is circulated to warm bath facility 32.
The mode that the power generation and heat supply device of present embodiment is sought to maintain generated energy certain operates.Therefore, control Power Generation Section 2, make the output of decompressor 25 certain.Such as, make the flow of recycle pump 27 certain, supply gas pressure and the exhaust pressure of maintenance decompressor 25 are certain, then the moment of torsion of decompressor 25 is certain, and the generated energy of generator 29 becomes certain.Therefore, the 1st vaporizer 18 in thermal source portion 1 and the water vapour of the 2nd vaporizer 19 or the flow of water of condensation can utilize the control gear of Power Generation Section 2 (not shown) to regulate.The generating adopting Rankine cycle heat engine is known, so omit the explanation of the detailed control of Power Generation Section 2.
The discharge-amount (rotating speed) of the raw water service pump 11 of solar boiler 4 water supply in heat source portion 1, is fixed on the setting flow D(such as 1t/h that preset suitable with the maximum capacity of solar boiler 4).Therefore, from the circulating water that solar boiler 4 flows out, the mixture of water vapour and hot water is generally.The circulating water flowed out from solar boiler 4 is separated into water vapour and hot water by the 1st steam-water separator 12, only water vapour is supplied to steam header 14.
Flow control device 23 regulates the discharge-amount of the raw water service pump 15 supplied water to biomass boiler 5, and making becomes the value (D-A) deducting the flow A of the steam that flowmeter 13 detects from setting flow D.Thus, the aggregate flow being supplied to the water vapour of steam header 14 from solar boiler 4 and biomass boiler 5 is made to be roughly setting flow D.
In addition, burning capacity control gear 24 controls the burning capacity of biomass boiler 5, makes the checkout value of pressure meter 22 be certain (such as the saturation vapor pressure of 0.26MPaG:140 DEG C).Thereby, it is possible to suppress the pressure oscillation of the water vapour being supplied to the 1st vaporizer 18 and the 2nd vaporizer 19 from steam header 14.
In addition, the control of burning capacity is not limited to the delivery volume consecutive variations making biomass fuel and combustion air, also can be the control periodically making burning capacity change, or utilize the unit number control of multiple stage boiler to be remained on by the checkout value of pressure meter 22 between certain pressure range (such as 0.17 ~ 0.26MPaG:130 ~ 140 DEG C saturation vapor pressure).Certainly, steam temperature is slightly declining between steam header 14 to the 1 vaporizer 18.
Like this, even if the exporting change of solar boiler 4, no matter i.e. weather or round the clock, the power generation and heat supply device thermal source portion 1 of present embodiment can both by roughly certain heat supply to Power Generation Section 2.
In addition, thermal source portion 1 makes circulating water change between gas phase and liquid phase and circulate in closed stream.Therefore, do not carry out the replacing of circulating water with outside, do not dissolve the concentrated of the material in circulating water, do not need the water supply of frequent make-up water or regular draining (ブ ロ ー).Certainly, the escape cock for the excessive situation of pressure also can be set, or the 1st condensation tank 10 or the 2nd condensation tank 17 be supplied to the inlet of make-up water in order to the water shortage of supplementing because discharge or other leakage cause.
In addition, present embodiment possesses the bypass heat exchanger 20 carrying out heat exchange between the water of condensation flowed out from the 1st vaporizer 18 and the 2nd vaporizer 19 in thermal source portion 1 and the warm water of heating part 3.Therefore, the heat being finally supplied to heating part 3 from thermal source portion 1 can be greater than the heat that coagulator 26 can supply.In addition, when reducing the heat being supplied to heating part 3 when comparing generated energy, cooling tower 34 chargeable heat is utilized.
And, in bypass heat exchanger 20, the temperature of the warm water of heating part 3 can be made higher than coagulator 26.
Like this, in the power generation and heat supply device of present embodiment, by possessing bypass heat exchanger 20, heat energy can be utilized expeditiously, thus can improve the thermal efficiency of power generation and heat supply device entirety further.
In addition, the electric power sent by Power Generation Section 2, can be connected with system and sell to power company etc., but also oneself consumes.In addition, village on a small scale can be also supplied to.
