Verdesis/Enalco 390A-TE RVS" is a model or type of gas turbine used in a CHP (Combined Heat and Power) system. The Enalco 390A-TE RVS heat exchanger is primarily identified as an exhaust gas heat exchanger and/or condenser, often used in Combined Heat and Power (CHP) systems with micro gas turbines (MGTs) or internal combustion engines (ICEs). "RVS" likely refers to "stainless steel" (roestvast staal in Dutch). Here's a breakdown of the specifications and characteristics based on the available information: Key Applications: Exhaust Gas Heat Recovery: Its primary function is to recover heat from hot exhaust gases generated by MGTs or ICEs. This heat is then typically transferred to a heating system, significantly improving energy efficiency (e.g., up to 20-30% energy savings with condensing). CHP Systems: It's a critical component in decentralized energy systems for simultaneous generation of heat, electricity, and sometimes cold (trigeneration). Condensing Heat Exchanger (CoHX): The "TE" in the model name suggests it's designed for condensing applications, meaning it can cool exhaust gases below their dew point to recover latent heat, further increasing efficiency. Typical Specifications (based on usage examples): Nominal Thermal Capacity (QN): For an MGT like the Capstone C65, the Enalco 390A-TE RVS has been cited with a nominal thermal capacity of 127 kW as an exhaust gas heat exchanger (MGTHX). When used as a condensing heat exchanger (CoHX), it's cited with a nominal thermal capacity of 16.8 kW. This difference highlights its specific role within the system. Material: The "RVS" indicates stainless steel construction, specifically T-316 Stainless Steel for tubes and tube sheets, often with a minimum thickness for durability. Construction: Often described as bare fire tube construction. Removable access covers are typically provided for easy inspection and cleaning of gas chambers without removing piping. Tubes are generally mechanically bonded and seal welded to the tube sheet, with all welds pickled and passivated for corrosion resistance. Performance Considerations: Gas Side Back Pressure: Designed to impose minimal back pressure on the gas side (e.g., not more than 5 inches of water column, "WC"). Exhaust Temperature Reduction: Sized to maximize heat recovery and reduce the exhaust temperature exiting the unit (e.g., to 248°F at 100% engine load). Water Side Pressure Drop: Typically designed for a low water side pressure drop (e.g., not to exceed 2.0 PSIG). Shell Side Design Pressure: Mentioned as 85 PSIG in some typical specifications. ASME Code Compliance: If water side temperature exceeds 210°F, it may be required to be built and "U" stamped per Section VIII of the ASME Code. Mounting: Can be provided with saddles for horizontal mounting or legs for vertical mounting. Duty: 146 kW Code: ASME VIII Div.1 Fluid (shell): water Fluid (tube): exhaust gas Pressure (shell): 6 bar Pressure (tube): 0.5 bar Temperature (shell): 99 °C Temperature (tube): 500 °C |
