Water absorbs heat in the boiler (or nuclear steam generator, waste heat boiler, etc.) to produce steam, which is then sent through pipelines to the turbine to expand and perform work, driving the generator to produce electricity. After performing work, the spent steam is directed to the condenser, where it is cooled by seawater, cooling water, or air, condensing back into water. This water is then sent back to the boiler through feedwater pumps for reheating, generating steam again. Some of the steam is also provided to the steam jet air ejector to maintain system vacuum, or it is used to heat feedwater heaters to form a regenerative cycle to increase overall thermal efficiency. Additionally, some steam is supplied to the deaerator to remove oxygen from the boiler water, thus forming a closed loop. This steam power cycle is known as the Rankine cycle.
We can provide various types of heat exchangers for power plants employing the Rankine cycle, as well as complete plant planning services. Whether it's for new plant construction, expansion, or retrofitting existing units, we can provide assistance.
