Powerhouse Waste Heat to Energy Project Final Report All generators are Westinghouse Premium efficiency (SF = 1.15) 480V 3 phase 100 HP induction motors. This makes for simplification of controls and a safe electrical system. 0DLQWHQDQFH 2SHUDWLRQ ± Turbo Thermal has determined that each unit would require 1.0 cents per kW-hr for maintenance over a one year period. This cost would include periodic inspection of the unit (lubrications, seals, performance) and cleaning of the units’ sea water heat exchanger and replacement of the drive belt. *(&OHDQ&\FOH These higher temperature ORC units are compact, relatively light weight, and can be broken down and rebuilt to allow for installation in smaller spaces. However, the evaporator and condenser components would have to be provided by the customer at additional cost. The estimated efficiencies are between 9.5% and 10.5% at 300F/55F hot/cold for the given flows and waste heat energy available from each of the Wartsila and Cat exhaust gas stacks. It’s estimated that each Wartsila @ 75% loading can energize 1.1 (137.5 kW) ORCs. It’s also estimated that the Cat @ 75% loading can energize 1.4 (175 kW) ORCs. 4. ExhaustGasBoilerEvaluationandIntegrationatPowerhouse Below are the design and construction constraints that should be considered when implementing the exhaust gas waste heat reclamation project. 1. The existing waste heat system, as designed, is connected and in common to the engine jacket water systems for Units 10, 11, and 13, and currently provides up to 195F water temperature. This temperature is too low for many ORC units to operate effectively, some manufacturers’ such as Electrotherm and potentially Ener-G-Rotors, can operate at reasonable efficiencies that can still economically justify the project. Modifications to the system flow rates will need to be implemented such that the waste heat peak temperature could be raised to 195F where these ORCs can be operate at better efficiencies. This modification could be implemented at any time at little to no cost. 2. During construction of the steel powerhouse new 8-inch waste heat transfer piping was installed between the steel powerhouse and the concrete powerhouse to allow for transfer of waste heat to the seawater heat exchanger and the then-future ORC units. However, higher temperature waste heat from the exhaust stack boiler may require the installation of new heat transfer piping from the exhaust gas boilers to the ORCs, which are to be installed on the first and/or second floor of the concrete powerhouse building. 3. Since the exhaust gas boiler lines could operate at much hotter temperatures (around 230 - 300F) than the engine jackets could handle it further suggests that a separate exhaust gas waste heat line be installed. 4. It was considered that the existing jacket water waste heat lines be cut, intercepted, and rerouted to the new gas boilers to save cost. However, after reviewing available BTU outputs from each heat source it was clear that removing the engine jacket waste heat lines would severely limit the availability of waste heat extraction as a whole. Therefore, since a substantial amount of the entire waste heat project centers around the engine jacket system it is critical to leave it intact and develop new higher temperature waste heat lines for the exhaust gas system. 10/22/2012 P a g e | 4-12PDF Image | Powerhouse Exhaust Gas Waste Heat to Energy Project
