Title: Pilot fruit drier for Los Azufres geothermal field, Michoacan, Mexico

Abstract

Comision Federal de Electricidad (CFE) has a Division in charge of the exploration of a geothermal reservoir located in Los Azufres, State of Michoacan. At present, CFE is only using the steam of the wells and rejecting the hot water that comes off associated with the steam. Based on a trip to the Los Azufres geothermal field in December of 1992, a design for a pilot geothermal fruit drier was undertaken for CFE. The details of the geothermal field and the local fruit production are detailed.

  • Comision Federal de Electricidad (CFE) has a Division in charge of the exploration of a geothermal reservoir located in Los Azufres, State of Michoacan. At present, CFE is only using the steam of the wells and rejecting the hot water that comes off associated with the steam. Based on a trip to the Los Azufres geothermal field in December of 1992, a design for a pilot geothermal fruit drier was undertaken for CFE. The details of the geothermal field and the local fruit production are detailed.
  • The main object of Comision Federal de Electricidad (CFE`s) Geothermal Field at Los Azufres, is to generate geothermal electricity; however with the new politics in Mexico CFE has built a pilot project in order to profit from the geothermal residual energy and to attract national or foreign investors and convince them that direct-use of geothermal energy is an attractive feasible and economical possibility. The object of this paper is to present the CFE experiences in wood and fruit drying using geothermal energy.

The object of this paper is to present the CFE experiences in different pilot projects applied to direct uses of geothermal energy.
  • Three distinct hydrothermal zones can be identified in the well A-29, located at the northeastern border of the Los Azufres, Mexico, geothermal field. They are the zeolite, epidote and amphibole-gamet zones. High temperatures (over 300{degrees}C) were measured, but the well did not produce mass flow. This can be explained by a self-sealing process as a result of three trends recognized in the evolution of geothermal fluids: boiling, boiling and gas losses, and dilution. A certain cooling of at least 25{degrees}C seems to be happening in the well, especially in the epidote zone and in the upper portions of the amphibole-gametmore » zone.« less
  • At present, 210 kg/s of brine are produced and injected in the Los Azufres geothermal field, using politethylene pipes. The scaling has occurred in these pipes and in the injector wells, mainly silica and, had been one of the main problems to solve in the operation of the field. Several tests have been made in order to minimize the scaling and to understand and to reduce the maintenance. At present the injection lines are cleaned using special tools to ream the internal diameter of the pipes. In this paper are presented the results obtained with the reamers and a discussionmore » on how to avoid the scaling in the injector wells.« less
