To produce of 1 kg of saturated steam from feedwater, about 1789/206 x 1 kg = 8.68 kg of primary coolant is required. Since the difference in specific enthalpies is less for primary coolant than for feedwater, it is obvious that the amount of primary coolant will be higher than 1kg.

Feedwater is then evaporated and the pressurized steam ( saturated steam 280☌ 536☏ 6,5 MPa) leaves the steam generator through steam outlet and continues to the steam turbine. The feedwater (secondary circuit) is heated from ~230☌ 446☏ to the boiling point of that fluid (280☌ 536☏ 6,5MPa). The feedwater ( water 230☌ 446☏ 6,5MPa) is pumped into the steam generator through the feedwater inlet. The primary coolant leaves (water 295☌ 563☏ 16MPa) the steam generator through primary outlet. The hot primary coolant ( water 330☌ 626☏ 16MPa) is pumped into the steam generator through primary inlet. Assume that there are no energy losses, this is only idealized example. Retrieved from Ĭalculate the amount of primary coolant, which is required to evaporate 1 kg of feedwater in a typical steam generator. Thermodynamic Properties of Water, NISTIR 5078. The properties are also tabulated for single-phase states ( compressed water or superheated steam) on a grid of temperatures and pressures extending to 2000 ✬ and 1000 MPa.įurther comprehensive authoritative data can be found at the NIST Webbook page on thermophysical properties of fluids. In these tables the basic and key properties, such as pressure, temperature, enthalpy, density and specific heat, are tabulated along the vapor-liquid saturation curve as a function of both temperature and pressure. Their properties are tabulated in so called “ Steam Tables”. Water and steam are a common medium because their properties are very well known. Steam Tables – common parameters in energy systems In almost all thermal power stations (coal, gas, nuclear), water is used as the working fluid (used in a closed loop between boiler, steam turbine and condenser), and the coolant (used to exchange the waste heat to a water body or carry it away by evaporation in a cooling tower). Water and steam also reacts with metals commonly found in industries such as steel and copper that are oxidized faster by untreated water and steam. It is especially effective to transport heat through vaporization and condensation of water because of its very large latent heat of vaporization.Ī disadvantage is that water moderated reactors have to use high pressure primary circuit in order to keep water in liquid state and in order to achieve sufficient thermodynamic efficiency. It used due to its availability and high heat capacity, both for cooling and heating. Water and steam are a common fluid used for heat exchange in the primary circuit (from surface of fuel rods to the coolant flow) and in the secondary circuit.
