“…Although the new design slightly decreases total system efficiency, the net MW‐to‐efficiency can reach 47.40%, far higher than conventional WTE plants, which typically range from 14% to 28%. [ 11 ] According to the previous results, it can be found that efficient use of MW can be achieved using recommended solutions.…”

Herein, a novel hybrid design that combines hazardous waste plasma gasification, gas turbine, supercritical CO 2 cycle, absorption heat pump, and coalfired combined heat and power (CHP) plant is proposed. In the integrated scheme, medical waste and concentrated solution of desulfurization wastewater are sent to the plasma gasifier and converted to syngas, which is conveyed into the gas turbine system after the necessary treatment. In terms of waste heat utilization of syngas and flue gas, some are used to drive the supercritical CO 2 cycle, some are used by the absorption heat pump for heating, and the rest are used to heat the feedwater of the coal-fired CHP plant directly. Based on a typical coal-fired CHP plant, the benefits of this system are examined in terms of both thermodynamics and economics. Once the heat supply and the net electricity from coal remain the same, the net power generated by the waste in the hybrid design is 18.45 MW, while the net wasteto-electricity efficiency reaches 47.40%. In just 4.76 years, the initial investment in the proposed system is recouped, and in its 25 year lifetime, the system achieves a net present value of 150,491.81 k$.

In this work, waste heat recovery, as a passive technique with low cost, is used for increasing the efficiency of a waste incineration CHP plant via an innovative way. Here, the recovered thermal energy is suggested to be used for the feedwater preheating process instead of steam extractions of turbines or any other auxiliary heat input for this purpose. For investigating the effects of the proposal, three different scenarios are considered and compared to each other. The first scenario is an old design waste CHP plant with a fuel-burning preheating process; the second scenario is a CHP plant with steam extractions from turbines for feedwater preheating; and the last scenario is when both of the previous preheating tools are removed from the cycle and instead, the energy of the exhaust gas of the incinerator is recovered and utilized for feedwater preheating. The energy, exergy, and economic analyses of the three scenarios are carried out, and the main performance factors of these power plants are compared. The results show that the efficiency of the heat recovered case considering both heat and power outputs can reach about 94% while the plants with old-fashion design and with steam extraction lines could give only 77% and 82% efficiencies. The exergetic efficiency of the proposed solution reaches the top value of 81% among the three scenarios, and its unit product cost will be lowest among all with a value of below 11 $/GJ. In the end, the effects of several operating parameters on the efficiency of the proposed system are investigated and reported.
