In a molten-salt solar power tower, liquid salt at 290oC (554oF) is pumped from a ‘cold’ storage tank through the receiver where it is heated to 565oC (1,049oF) and then on to a ‘hot’ tank for storage. When power is needed from the plant, hot salt is pumped to a steam generating system that produces superheated steam for a conventional Rankinecycle turbine/generator system. From the steam gener...

Abstract In this paper, a practical study was conducted with and without solar panels to show their effect on the performance of hybrid chimney in city Kirkuk Iraq. Six cells were placed between base collector glass cover, which gives freedom air move up down cells. Also, it is showed that speed higher when using PV until reaches 1.8 m/s while leaving energy coming out efficiency chimney. The r...

Due to the rapid increase in deployment and high penetration of solar power generation worldwide, solar power generation forecasting has become critical to variable generation integration planning, and within utility and independent system operator (ISO) operations. Utilities and ISOs require day ahead and hour ahead as well as intra-hour solar power forecasts for core operations solar power pr...

Concentrating Solar Power (CSP) plants utilize thermal conversion of direct solar irradiation. A trough or tower configuration focuses solar radiation and heats up oil or molten salt that subsequently in high temperature heat exchangers generate steam for power generation. High temperature molten salt can be stored and the stored heat can thus increase the load factor and the usability for a CS...

In recent years, energy consumption from electrical devices to foster air movement in regions with warm climates has risen, the resulting negative impact on environment. The purpose of this paper is evaluate performance a solar chimney used induce natural ventilation closed space, under weather conditions hot humid Mexican climate. For purpose, CFD simulations were run using RNG k- ɛ turbulence...
