ONCE-THROUGH BOILERS

Feb 02 2011 · Once-through boilers are generally associated with high pressure operation and the feed water enters at high sub-critical (>180 bar) or supercritical pressure whilst superheated steam leaves at a pressure some 2030 bar lower. Sliding pressure operation is adopted to accommodate requirements of part-load running. Figure 1.

Once Through Steam Generators - Nooter/Eriksen

Once Through Steam Generators (OTSGs) are very similar to Heat Recovery Steam Generators (HRSGs) except for the actual process of steam generation in their evaporator section (s). N/E under a license from Siemens AG utilizes two single pass evaporator stages to evaporate and partially superheat the steam flow in the evaporator section. The primary stage evaporates the water to an

Sep 20 2016 · Todays supercritical boilers burn pulverized coal and are considered once-through boilers meaning that they do not require a drum to separate steam from water. Rather than boiling water to produce steam and then using that steam to turn a plants turbine a supercritical operates at such high pressure (3208 psi/221.2 bar or above) that the fluid matrix in it ceases to be liquid or gas.

Introduction of High-efficiency Once-through Boiler System ...

In this project a high efficiency one-through boiler (gas type) is introduced for energy saving. This one-through boiler with PI control better manages the combustion and feed waster supply which contribute to increased boiler efficiency and stable steam supply. For instance it can achieve maximum efficiency of 98% (95-97% under practical condition) whereas the efficiency of conventional fire tube and water tube

Mitsubishi Power Ltd. | Once-through Boilers

Once-through boilers are able to produce steam at higher pressures and temperatures than drum boilers. In thermal power plants raising steam conditions (pressure and temperature) can enable efficiency gains in power generation equipment allowing an operator to reduce its fuel consumption and CO 2 emissions. Mitsubishi Power delivered its first supercritical pressure - in 1968 and followed up in 1981 with delivery of the first supercritical variable pressure - ...
