To date, Israel's electrical energy has been based only on imported fuels. However, with the recently discovered natural gas in the Ashqulon shores, Israel can examine the benefits to its energy resources, environment, and economy of blending its domestic natural gas with imported coal. As for using natural gas, the proposal is to burn it in existing IEC coal-fired boilers in order to significantly reduce NOx emission by reburning. An important aspect is to provide retrofitting in existing IEC boilers by replacing a fraction of the coal by natural gas. This would allow the purchase of coal with a wide range of parameters, which is less expensive. Hence, mixed gas-coal burning would benefit Israel. The authors have made numerical simulations in order to study the optimal conditions of operation and evaluate the economic as well as environmental benefits. Indeed, extensive simulations have shown that there is a significant reduction of NOx emission, as expected, with the addition of relatively small amounts of natural gas. Experiments will now be carried out in a test facility that will provide accurate physicochemical properties of the mixed fuel for more reliable simulations. 19 refs., 6 figs., 1 tab.
