Datacor Fathom was used to size pumps, heat exchangers, and control valves, and to validate line sizing to ensure that piping was within design requirements for the system.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Analysis<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The system has several duty cycles including heat storage and heat extraction cycles. The Scenario Manager in Datacor Fathom was used to model these cycles and the heat storage cycle was modeled with and without the heating condenser. Other modes that were modeled were summer operation, steady-state heating with different combinations of industrial heat supply, and heating condenser supply (including high pressure condensation). Steam turbine trips were simulated for each operating mode. Minimum flow, maximum flow, and pump trip scenarios for various pumps were also modeled.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Design Alerts were used to ensure that all pipes had flows below maximum mass flow and velocity limits, limits which varied for pipes of different sizes in different areas of the system. Datacor Fathom results validated pipe sizing choices and allowed pumps, control valves, and heat exchangers to be sized appropriately.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Solution<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The plant utilizes waste heat by means of heat pumps from local industrial processes including three manufacturing plants, a dam, a waste incinerator, and a sewage treatment plant. Within the heat cycle, the industrial heat recovery consists of three pumps and six heat exchangers. Water returned from these sources collects additional heat by condensing steam generated from the facility\u2019s gas turbine, a crucial step for the turbine\u2019s power cycle (Figure 1).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Downstream of the heat extraction subsystem, a secondary water system transfers heat from the thermal cycle into the municipal district heating network of Hamburger Energiewerke using three pumps and five heat exchangers (Figure 2). In the summer or when excessive heat is available, water can instead be diverted to an air-cooling system to dissipate heat.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The heat storage system consists of a 50,000 m3 (13,200,000 gallons) tank which provides additional pressure to the heat extraction pumps to prevent cavitation and can be used to pressurize the district heating system or supply it with a portion of its hot water directly as an emergency heat supply. Heat from the cycle is also supplied to auxiliary systems including a natural gas preheater, on-site heating, and antiicing heat exchangers.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/flumen.clients.cake.fm\/wp-content\/uploads\/2026\/07\/CS_Fathom_ENKA_26_02.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">Read the article<\/a><\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"Problem Kerem Alg\u00fczey, design engineer at ENKA Insaat ve Sanayi A.S., used Datacor Fathom to simulate the central heating cycle to inform the design of the hydraulic thermal system for the Dradenau Combined Heat and Power Plant under construction in Hamburg, Germany.
