This paper describes an approach to the development and characterization of a solar-assisted coal gasification plant. Two solar receivers for steam coal gasification, both on a sub pilot scale, have been designed and set up at the Weizmann Institute`s solar facilities for tests under the conditions of highly concentrated solar radiation. In spite of the fact that chemical reactors of different types, one-tubular and the second-volumetric, have been installed in each of these receivers, they have in common the integration of a reactor and associated steam generator into one complex solar thermal system. The receiver constructed of a reaction tube coupled with a superheated steam generator provides processing of grained carbonaceous materials at temperature as high as 900--950 C with a sufficiently high rate of the syngas yield. Results from a series of the windowed reactor/receiver tests are also successful, demonstrating the suitability of this reactor for operating in a wide range of conditions required for coal gasification. Being designed in a certain degree of simplicity, that is adequate to the present stage of problem initiation, the receivers employed need to be optimized in order to achieve considerable efficiency of solar thermal power conversion into the energy of product gas. Results show that the temperature of process steam can strongly influence the system performance.
