Abstract
The goal is to analyze and compare the three most common solar steam production technologies without thermal storage integrated into a conventional 1 MW steam production system through modeling, simulation and solar field size optimization through payback period and fuel saving by Direct Normal Irradiation (DNI), ambient temperature, and wind speed in two locations: one with high DNI, high temperature and low wind speeds and the other with lower DNI, lower temperatures and higher wind speed. The most economically viable system without thermal storage is the Direct Steam Generation system. However, higher operating temperatures make the use of systems that use water as a heat transfer fluid prohibitive. In these cases, the most suitable system, among those analyzed here, is the Unfired Boiler system. In addition, it is suggested that the advantages and disadvantages of each technology be considered according to the peculiarities of each case, such as safety and environmental risk issues. The factors that determine the feasibility of installing a solar thermal system are the fuel price, quantity of solar resource and the type of technology employed. However, fuel price and availability of solar resource are more relevant factors for economic viability than the type of technology employed.
