measuring the quality and quantity of brown coal before and after storage; with this system, the fuel is adequately selected and the heat rate is optimized; ii) replacement of high-pressure water mist with cold water from the high-pressure heater; iii) installation of steam traps in outlet lines, to eliminate losses and save on the energy required to produce demineralized water for make-up of the closed circuit; and, finally, iv) reliance was made on a new integrated water management system, which saves water and electricity due to the reduced operation (and related consumption) of pumps withdrawing water for industrial uses.
