Finn-Aqua T-Series Pure Steam Generators | STERIS - STERIS Life …
STERIS's Finn-Aqua Pure Steam Generator (PSG) utilizes a falling-film type evaporator which produces pyrogen free pure steam, using a unique separation technology. Feed water is continuously pumped to the top of the evaporator heat exchanger, heated by plant steam.
Steam Generator - an overview | ScienceDirect Topics
Large reactors mostly use recirculating steam generators (RSG). While for SMRs, once-through steam generators (OTSG) are preferentially adopted. In an OTSG, the flow in the secondary system is forced circulated by feed-water pumps.
The primary function of a steam generator is to generate steam under pressure, but modern steam generators are also required to do the following: i. Ensure generation of exceptionally high-purity steam by eliminating all impurities from saturated steam. ii. Raise the degree of superheat of supplied steam as specified and maintain the
High-Pressure Steam Generators - Sigma Thermal
The NUK® High-Pressure Steam Generator is a closed-looped (hermetically sealed) system that produces steam for high-temperature applications. Therefore, this steam generator is able to produce non-toxic process heat while offering the same advantages of a …
FINN-AQUA Pure Steam Generators are designed with our environment in mind. Lower utility consumption means less operating costs for you and saves energy for our environment. FINN-AQUA Pure Steam Generators use: > Less Plant Steam – The effective falling film evaporation and patented water distribution to the column enables a high

Calculate the pump pressure necessary for the given flow. Also, calculate the mass flow rate through the downcomer. 2‐ A drum type steam generator operates at (160 bar). (1260 kg/s) of saturated water goes down the downcomer. The downcomer and risers are all (12 m) high. The average water‐ steam mixture density in the risers is (350 kg/m3).
Finn-Aqua T-Series Pure St eam Generators (PSG) are designed to consistently generate Pure Steam for use in clinical research, pharmaceutical and biotech industries. The Pure Steam is used for sterilization applications such as sterilizers, Steam-in-Place (SIP) systems, sterilization of tanks, mixing vessels and
Thermal hydraulic simulation of the steam generator under fast ...
2023年1月1日 · The computational model of the overall steam generator is achieved by combining full 3D simulation in the riser and 0D modeling with ad hoc Dynamic Boundary Conditions (DBC) in separator/dryer, downcomer, and pre-heater regions.
Riser and downcomer for natural circulation HRSG drum.
In this paper, we present a simple procedure to build a model of a heat recovery steam generator (HRSG) evaporator and drum within the environment of MATLAB/Simulink. The HRSG is part of...
