Abstract

The present invention relates to a process for production of clinker and electricity comprising the following steps: introduce the raw meal (102,102 ) fuel (121,121 ) and a combustion agent (113,113 ) in at least two precalciners (3,3 ) positioned in parallel precalcine the raw meal at a temperature of from 750 to 950°C in order to obtain precalcination flue gases (132,132 ) and a precalcined raw meal (103,103 ) treat the precalcination flue gases (132, 132 ) and the precalcined raw meal (103,103 ) towards respective cyclones (4,4 ) in order to obtain precalcination flue gases (133,135) and a precalcined raw meal (104,104 ) clinkerise the precalcined raw meal (104,104 ) in order to obtain clinker (105) produce steam by transmission of heat from at least one part of the flue gases (135) coming from at least one secondary precalciner (3 ) and the corresponding cyclone (4 ) produce electricity (150) from this steam using an electricity generator (6) comprising a steam turbine and steam generator (7) vary the feed rate of raw meal and/or the flow rate of fuel and/or the flow rate of combustion agent in at least one secondary precalciner (3 ) to vary the quantity of electricity produced introduce into at least one secondary precalciner (3 ) a flow of a dilution flue gas (138 ) this flow being in particular formed from one part of the precalcination flue gases having already transmitted their heat wherein the precalcination flue gases (135) coming from the at least one secondary precalciner (3 ) and the corresponding cyclone (4 ) are diluted before transmitting their heat to obtain diluted precalcination flue gases (136) in particular with a fraction (137) of these precalcination flue gases having already transmitted their heat.
