Mini coal-fired CHP plant on the basis of synthesis gas generator (CO+H2) and electrochemical current generator

摘要

The paper deals with synthesis gas (syngas) for electrochemical generator produced in the gas generator with autothermal steam gasification of coal from Borodino deposits. Here, thermal balances of the battery of solid oxide fuel cells (SOFC) and boiler intended for producing the superheated water steam for a gas generator and for heating the cathode air have been compiled. On the base of these balances, the fractions of hydrogen and SOFC oxidized in anode as well as the electrical efficiency, the temperature in anode and the loss with flue gases and to the surrounding through the thermal insulation along with the fuel cell EMF have been calculated. Besides, the specific consumption of Borodino coal for producing electrical and thermal power has been determined. (C) 2017 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
