In the development of a Linear Fresnel Reflector (LFR) system, the calculation of temperature distribution, steam quality and pressure drop are very important. So, in this paper, was developed a mathematical model for the thermo-hydraulic calculations in steady-state on the LFR system, where the differential equations originated from of the thermal balance, of the continuity equations, of the linear movement quantity and in the energy equation were solved simultaneously. The developed model allows the calculation of the variation of temperature of the working fluid along the tube, pressure drop troughout the system and the variation of the heat flux, for different conditons of direct normal irradiance(DNI). With the obtained results was possible to comprehend the behaivor of the fluid for different DNI conditions, and observe that this parameter is very important in the simulation of the LFR system.
