Description

Es ist auf 10 m3 NaNO2 und auf eine Arbeitstemperatur von 300 °C konzipiert.It is designed for 10 m 3 NaNO 2 and a working temperature of 300 °C.

Der Behälter besteht aus 10 mm dickem Stahlblech, der thermisch und statisch stabil sein muss. Die Stahlsorten können z.B. 13CrMo4.4; 10CrMo9.10 oder X20Crl3 sein.The container consists of 10 mm thick sheet steel, which must be thermally and statically stable. The steel grades can be e.g. 13CrMo4.4; 10CrMo9.10 or X20Crl3.

Bevor der Satz in den Behälter eingelagert wird, muss es innen metallisch rein sein. Der Wärmespeicherblock arbeitet drucklos und muss nach außen gut isoliert werden.Before the set is stored in the container, it must be metallically clean on the inside. The heat storage block works without pressure and must be well insulated from the outside.

Die Heizelemente im Block können mit Gleich- sowie Wechselstrom betrieben werden. Um eine Temperatur von 300 °C und 10 m3 Salz zu erwärmen, benötigt man rund 2,3 MW.The heating elements in the block can be operated with direct and alternating current. Around 2.3 MW is required to heat a temperature of 300 °C and 10 m 3 of salt.

Mit dieser Speicherwärme wird durch Wärmeaustauscher Dampf erzeugt und die Turbinengeneratoren können wieder Strom erzeugen. Je nach Dampfdruck, können mehrere Turbinen in Reihe geschaltet werden.With this stored heat, steam is generated by heat exchangers and the turbine generators can generate electricity again. Depending on the steam pressure, several turbines can be connected in series.

Dieses Prinzip ist ähnlich dem eines Atomkraftwerkes.This principle is similar to that of a nuclear power plant.

Dort wird im Kernreaktor durch Brennstäbe im Primärkreislauf Wärme erzeugt und auf den Sekundärkreislauf übertragen. Dieser erzeugt Dampf und treibt den Turbinengenerator an, wobei Strom erzeugt wird.There, heat is generated in the nuclear reactor by fuel rods in the primary circuit and transferred to the secondary circuit. This generates steam and drives the turbine generator, generating electricity.

Das erste in der Sowjetunion betriebene Atomkraftwerk hatte eine Leistung von 5000 kW. Bei 300 °C Betriebstemperatur war ein Druck von mindestens 100 at erforderlich. Atomkraftwerke sind sehr kostspielig und gefährlich.The first nuclear power plant operated in the Soviet Union had an output of 5000 kW. At an operating temperature of 300 °C, a pressure of at least 100 at was required. Nuclear power plants are very expensive and dangerous.

Durch den weiteren Ausbau der erneuerbaren Energie wäre das eine Alternative zur besseren Auslastung der Stromerzeugung.The further expansion of renewable energy would be an alternative to better utilization of power generation.

Mit freundlichen GrüßenBest regards

Zur Ergänzung der SpeicherleistungTo supplement storage performance

Zu diesem Speicherblock kommt der Stahlbehälter dazuThe steel container is added to this storage block

Der Behälter hat eine Gesamtfläche von 640 m2. bei 10 mm Blechdicke ergibt ein Volumen von 6,4 m3 Stahl Stahl = 7,8 g/cm3 1 dm3 = 7800 g Q = 7800 g × 280 °C/300 °C - 20 °C Q = 2184000 cal × 4,1868 J Q = 91439712 J : 3600000 WS Q = 2,539992 Kwh Q = 2,54 Kwh × 1 m3 Q = 2540 Kwh × 6,4 m3 E = 1625600 Kwh E = 1 Kwh = 3,6 MJ E = 1625600 × 3,6 MJ E = 5852160 MJ The container has a total area of 640 m2. with a sheet thickness of 10 mm results in a volume of 6.4 m3 of steel steel = 7.8 g/cm3 1dm3 = 7800g Q = 7800g × 280°C/300°C - 20°C Q = 2184000 cals × 4.1868 J Q = 91439712 J : 3600000 WS Q = 2.539992 kWh Q = 2.54KWh × 1m3 Q = 2540 kWh × 6.4 m3 E = 1625600 kWh E = 1 KWh = 3.6 MJ E = 1625600 × 3.6MJ E = 5852160 MJ

Aus den Berechnungen zur Wärmespeicherung ergeben sich NaNo2 = 2,17 g/cm3 1 dm3 = 2170 g Q = Masse × Temperatur = Cal Q = 2170 g × 280 °C/300°C - 20 °C Q = Cal × J Q = 607600 × 4,1868 J Q = 2543899,68 J Q = 2543899,68 J : 3600000 WS Q = 0,706 Kwh Q = 0,706 Kwh × 1 m3 = 706 Kwh Q = 706 Kwh × 10 m3 = 706638 Kwh E = 1 Kwh = 3,6MJ E = 706638 Kwh × 3,6 MJ E = 2543899,68 MJ From the calculations for heat storage result NaNo2 = 2.17 g/cm3 1dm3 = 2170g Q = Mass × Temperature = Cal Q = 2170g × 280°C/300°C - 20°C Q = Cal × J Q = 607600 × 4.1868 J Q = 2543899.68 y Q = 2543899.68 J : 3600000 WS Q = 0.706 kWh Q = 0.706 kWh × 1 m3 = 706 kWh Q = 706 kWh × 10 m3 = 706638 kWh E = 1 KWh = 3.6MJ E = 706638 kWh × 3.6 MJ E = 2543899.68MJ

Die Gesamtenergiespeicherung beträgt aus 10m3 NaNO2 + 6,4 m3 Stahl

  • - 706638 Kwh + 1625600 Kwh
  • - 2332238 Kwh
Total energy storage is from 10m3 NaNO2 + 6.4m3 steel
