An analysis of existing methods for calculating heat and mass transfer processes in porous absorbers of receivers of tower solar power plants is carried out.

Thermal absorbers and their integration methods are critical to solar photovoltaic/thermal (PV/T) modules. These two elements directly influence the cooling effort of PV layers and as a result, the related electrical/thermal/overall efficiency.
For solar thermal conversion processes, heat can be generated by efficiently absorbing the incident solar photons from the solar radiation with wide applications such as solar water heating system, solar thermal electricity
Lanzhou Dacheng Technology Co., Ltd. has established a number of solar thermal power stations, including 50 MW molten salt linear Fresnel solar photo-thermal demonstration power station [49].

The molten salt solar power tower station equipped with thermal energy storage can effectively compensate for the instability and periodic fluctuation of solar energy, and a reasonable operation control strategy is essential for its peak-regulating operation mode. Based on the law of conservation of energy and conservation of momentum, the dynamic model of a
In the absence of any other heat losses, the black body absorber will heat up until it reaches the same temperature as the source, and it will then be in equilibrium. This implies that (2.8) σ T s 4 A c sin 2 θ = σ T R 4 A R, where T R is the absolute temperature of the receiver and T s is the temperature of the sun''s surface. Since T R = T s at equilibrium, g this gives the

This value may vary depending on the location of the power station. In regions with abundant solar radiation, such as North Africa, the EPT can be reduced to 3.19 years. The CCOE result for the CSP-T station is 0.04 kg CO 2 /kWh, accounting for 57.14 % of PV stations and only 6.73 % of coal-fired power stations.
Thus, solar thermal power stations can also be used for grid stabilization and a need-based power production. The parabolic trough, the solar dish, the Fresnel collector, and the solar tower belong to the group of solar thermal power systems. Parabolic trough and the solar tower are already competitive and economically feasible.
A solar thermal power station consists of a conventional block-unit power station and a solar component which replaces the combustion chamber of a conventional power station. Such power stations reach annual nominal loads of up to 3000 h in locations of high irradiation (e.g., North Africa).
