Improvement of the Cogeneration Plant Economy by Using Heat Accumulator

The optimisation code ACOM is used with purpose of assessing influence of the district heat accumulator on the EL-TO Zagreb cogeneration plant economic performance. The plant supplies hot water for district heating, process steam for industry and electric power. It is possible to achieve economic benefits by charging the accumulator during day time when electricity price is high and by realising district heat during cheap night hours when other parts of equipment may be shut down. The consequences of this strategy are the decrease of total annual electricity production and fuel consumption whereby the savings are achieved of some 1.8 mil Euro/a with reduction of CO2 emission for about 23, 000 t/a or 6.4 % and SOx for about 200 t/a or 16.9 %.
