Coil-Type Steam Generators for Heating Plant Applications

The once-through coil-type steam generator (Figure 3) differs significantly from the recirculation design in that the water is pumped through a series-con-nected multiple coil assembly and then into an integral cyclonic separator. This results in approximately 90 percent of the water being converted to steam with a dryness fraction greater than

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 20–30 bar lower. Sliding pressure operation is adopted to accommodate requirements of part-load running.

Transient models and characteristics of once-through line

Fresnel solar fields, in which there is a long section of two-phase flow. In the once-through mode (OTM), feed water from the power block is directed to the inlet of a loop. The water is then preheated, completely evaporated and superheated along the loop. This paper presents two different types of transient models for such systems.

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 once-through boiler in

In once-through boilers the determination of specific enthalpy after the evaporator is based on the temperature. The reason for this is the unclear state of supercritical steam after the evaporator in once-through circulation. The temperature after the evaporator in once-through boilers is typically between 400 and 450 °C. 4.
