Universally Applicable Design Concept of Stably Controlling an HTGR-Hydrogen Production System.

design of an analog fuzzy logic controller chip

fuzzy logic has been developed over the past three decades into a widely applied techinque in classification and control engineering. today fuzzy logic control is one of the most important applications of fuzzy set theory and specially fuzzy logic. there are two general approachs for using of fuzzy control, software and hardware. integrated circuits as a solution for hardware realization are us...

Conceptual Design of an Htgr System for a Total Energy Application

A conceptual design for a small HTGR in the 100 MWe size range is described. The reactor drives indirect closed-cycle gas turbine power conversion units using helium as the working fluid and provides both electricity and thermal energy (via a 3800 F hot-water utility system) to serve the projected needs of large U.S. Army installations and industrial facilities in the continental U.S. in the po...

methods of controlling hydrogen sulfide production and emission in seweragee

sulfide production has been one of the most important problems in sewage collection systems that came to be known as an important factor of corrosion in concrete sewerage systems since early 1900. the emission of hydrogen sulfide gas in sewerage conduits creates problems including biological corrosion of concrete, release of repulsive odors in the city environment, as well as the potential dang...

One-Dimensional Electrolyzer Modeling and System Sizing for Solar Hydrogen Production: an Economic Approach

In this paper, a solar based hydrogen production in the city of Tehran, the capital of Iran is simulated and the cost of produced hydrogen is evaluated. Local solar power profile is obtained using TRNSYS software for a typical parking station in Tehran. The generated electricity is used to supply power to a Proton Exchange Membrane (PEM) electrolyzer for hydrogen production. Dynamic nature of s...
