Waste heat water pumping model with direct contact cooling

摘要: The performance of a patented water pumping model with steam-air power was presented, which operates automatically by direct contact cooling method. main objective to study feasibility for underground water. In this model, heater installed within the heat tank represented sources waste as energy input finding appropriate conditions 10 L pump model. system operation had five stages: heating, pumping, vapor flow, cooling, and suction. overall heads 3, 4.5, 6 7.5 m were tested. At same time, it found that 50% air volume is sufficient desired level. experiment, temperatures in heating stages 100–103 °C 80–90 °C, respectively. pressure stage 12–18 kPa, suction about −80 best performance. It could 170 at 2 head, 120 3.5 100 5 65 6.5 head h. A mathematical larger pumps also nearly present system. Economic analysis included.
