Abstract

This article relates to diesel engineering and can be used by design organizations and river fleet vessels in operation. The device of the energy-saving installation of a river vessel uses a heat pump with a high-temperature two-stage compressor and an Organic Rankine Cycle (ORC). In a two-stage compressor, the temperature of the low-boiling substance reaches 100°C. Further, this steam is condensed in the ORC condenser, while the coolant is heated to 95-98°C and the resulting coolant is distributed through a three-way valve: part of the coolant flow enters the heating object, the other part of the coolant enters the ORC evaporator through a three-way valve, where heat exchange with a low-boiling substance takes place. The resulting high-pressure steam then enters the turbine. In this case, the steam turbine is driven with a generator and electrical energy is generated. The proposed energy-saving installation can be used by river vessels during cargo operations and forced stops, during which the power plant: the main marine diesel engine, diesel generator and auxiliary boiler plant are inoperative, which leads to significant fuel savings of the ship power plant.

内河船舶的节能装置

本文涉及柴油机工程，可供设计机构和运营中的内河船队船舶使用。内河船舶的节能装置使用带有高温双级压缩机和有机郎肯循环（ORC）的热泵。在双级压缩机中，低沸点物质的温度达到 100°C。然后，蒸汽在 ORC 冷凝器中冷凝，冷却剂被加热到 95-98°C，产生的冷却剂通过三通阀进行分配：一部分冷却剂流进入加热物体，另一部分冷却剂通过三通阀进入 ORC 蒸发器，与低沸点物质进行热交换。随后，产生的高压蒸汽进入汽轮机。在这种情况下，蒸汽轮机由发电机驱动并产生电能。建议的节能装置可在内河船舶进行货运作业和被迫停航时使用，在此期间，动力装置：主船用柴油机、柴油发电机和辅助锅炉装置均不工作，从而大大节省了船舶动力装置的燃料。
