About the ecological aspects of dual fuel combustion in thermopower plants

Experimental Investigation of Dual-Fuel Combustion Characteristics inside a Gas Turbine Combustor

“…Combustion and fluid flow characteristics of coflowing LPG and kerosene have been investigated experimentally by Abdel-Latif [5]. The possibility of dual fuels applications in existent thermopower plants in order to enable their pollutant emissions to conform to the ecological norms, which limit their values were analyzed by Mircea and Malvina [6]. The effects of nitrogen injection into the near-nozzle region of a liquid (kerosene) spray flame produced from a twin-fluid atomizer was experimentally studied by Gollahalli and Puri [7].…”

“…Some of the previous investigators concerned with studying the combustion characteristics of dual fuel in gas turbine combustor but as additives to combustion air [4][5][6][7][8][9]15], none of them concerned with studying the combustion characteristics of dual fuel in gas turbine combustor with both fuels (gas and liquid) introduced into the combustion chamber coaxially as diffusion flame, in addition to swirling and none swirling gaseous fuel (the task of the present study). Therefore, the present work perhaps gives effort to use the dual fuel technique in gas turbine combustor to enhance the evaporation rate of liquid fuel.…”

Energy, Exergy, Economic, Environmental (4e) Analysis of Hybrid Systems for Electricity Generation From Municipal Solid Waste and Natural Gas

“…-Cardu & Baica [101] propose the first approach to dual-fuel thermopower plants, evaluating the combination of coal and fuel-oil with methane and hydrogen.…”

“…In this section is presented another original contribution in the methodological level. First, a review is presented of the existing method for evaluating dual-fuel facilities proposed by Cardu&Baica [101]. They suggest to consider the plant fueled by a fictitious "hybrid fuel" composed by fuel 1 (fuel with greater mass = primary fuel) and fuel 2 (supplementary fuel), whose lower heating value (LHV d ) can be obtained through a weighted average of each fuel's LHV, according to eq.…”

“…, where always n d < 1. Thus, LHV d does not refer to 1 kg of dual-fuel, but to a "package" formed of 1 kg of primary fuel and n kg of supplementary fuel [101]. The equivalent emission factor of the "dual fuel" (f eq ) d can be calculated generally for all approaches as:…”
