  • The Factors Used in Policy Decision Making for Promoting Direct Steam Generation Parabolic Trough Technology in Thai Food Industry
    International Journal of Renewable Energy, 2017
    Co-Authors: Jakkrapun Kongtana, Prapita Thanarak
    Abstract:

    Direct steam generation from boilers is the most common technique, currently applied in Thailand food industry. To reduce its fossil fuel consumption and GHG emission, industry is focusing on the development of renewable energy technologies, and direct steam generation from parabolic trough is one of them. This study discusses decision making factors for promoting the use of direct steam generation in Industrial Heat Process by parabolic trough technology. The factors were evaluated and applied by using literature review, personal communication with key personnel and questionnaires. The Analytic Network Process (ANP) was applied to suggest a ranking scale for the factors to be used in drafting their weights. The considered main factors were technology, economics, social, environmental and political. The results suggest that the financial mechanism, investment cost, technological maturity, reliability, safety and environmental gains can be used in decision making for the promotion of renewable energies in Thai food industry.

  • Numerical simulation of a parabolic trough solar collector for hot water and steam generation
    2016
    Co-Authors: Ahmed Amine Hachicha
    Abstract:

    Parabolic trough solar collectors (PTCs) are currently one of the most mature and prominent solar technology for the production of electricity. In order to reduce the electricity cost and improve the overall efficiency, Direct Steam generation (DSG) technology can be used for Industrial Heat Process as well as in the solar fields for electricity production. In the last decades, this technology is experiencing an important development last decades and it is considered as one of the most feasible Process for the next generation of power plants using PTCs. A numerical model based on Finite Volume Method (FVM) balance is presented to predict the thermal behavior of a parabolic trough solar collector used for hot water and steam generation. The realistic non-uniform solar flux is calculated in a pre-Processing task and inserted to the general model. A numerical-geometrical method based on ray trace and FVM techniques is used to determine the solar flux distribution around the absorber tube with high accuracy.

  • Modeling of a small parabolic trough plant based in direct steam generation for cogeneration in the Chilean Industrial sector
    Energy Conversion and Management, 2018
    Co-Authors: Carlos Valenzuela, Carlos Felbol, Gonzalo Quiñones, Loreto Valenzuela, Sara L. Moya, Rodrigo Escobar
    Abstract:

    Abstract The concentrated solar power technology used in schemes of cogeneration for the production of power and Heat, or power and cooling is an interesting option to develop in Chile, mainly due to the high solar potential. Besides, cogeneration is an option to face the demand for energy in terms of electricity, Industrial Heat or cooling, which is increasing in Chile in recent years. A concentrated solar power cogeneration plant based in parabolic trough technology with a backup system of a biogas Heater and a direct steam generation scheme is proposed. The cogeneration study considers two different plants, one for power and Heat, and other for power and cooling, which were studied in Santiago, Chile. The results show a benefit in fossil fuels replacement when the cogeneration plant is compared to a conventional plant for production of Industrial Heat. In the case of cooling, electricity savings are achieved when the cogeneration plant is compared to a conventional vapor-compression system. The cooling demand can be supplied totally using an absorption chiller in the cogeneration scheme, reaching electricity energy saving of up to 99%. For cogeneration of power and Heat the energy replacement in the Industrial Heat Process are as minimum 69% depending on the demand and configuration of the plant, and can reach up to 100%. Finally, when the biogas Heater is disconnected from the plant to consider a case only based in the concentrated solar power plant, the cogeneration scheme for cooling can reach an electricity saving of 4%. The cogeneration scheme for Heat can reach an energy replacement of 14% as minimum.

  • Techno-economic Influence on Malaysia’s Solar Thermal Installation for Heating Process
    Indonesian Journal of Electrical Engineering and Computer Science, 2018
    Co-Authors: Anis Sabirin Baharom, Nofri Yenita Dahlan
    Abstract:

    This paper presents System Dynamics simulation and Techno-Economic analysis to estimate the techno-economic benefits and reliabilities of solar Heating. The study focuses only on Industrial Heat Process in Malaysia. The main objective of the current work was to investigate the solar thermal installation feasibility by Malaysian Industrial Heat Process for next 20 years. The solar thermal installation was measured through the techno-economic feasibility (TEF) study by developing the TEF model using System Dynamics Simulation (SDS). subsidy, net solar thermal cost, and NPV are used as economic influence factors. System performance, solar thermal life time, energy, solar fraction and size of collector area are used as technical influence parameters. Results have shown that the economic factor has a bigger influence on solar thermal installation capacity in Malaysia. The technical factors only contribute small percentage to the installation percentage. Policy maker could benefit from the outcomes obtained as a guideline.
