MOISTURE SEPARATOR<br />
REHEATER<br />
For many decades now <strong>Balcke</strong>-<strong>Dürr</strong> moisture separator reheaters<br />
(MSRs) have been setting benchmarks world-wide in terms of<br />
efficiency, reliability and quality workmanship. As pioneers in<br />
technological development, we supplied the MSRs for one of the<br />
first German nuclear power plants in 1968. Since then most of the<br />
nuclear power plants in Germany as well as numerous international<br />
sites have been equipped with our MSRs.<br />
By fitting out the first European Pressurized Water Reactor<br />
(EPR), we are accomplishing our declared aim of always tailoring<br />
the design of our MSRs to tomorrow‘s requirements. The MSRs<br />
developed for the EPR are therefore not only the world’s largest<br />
and longest-lasting but are also equipped with the most advanced<br />
separation technology, namely “Powervanes”. Upstream “Powerseps”<br />
ensure optimal component protection.<br />
Our product range based on proven, practical designs<br />
covers all the conventional types of construction: MSRs<br />
in vertical or horizontal configuration with single or two-stage<br />
reheating system. Our comprehensive spectrum of supplies and<br />
services extends from CFD analyses and model tests to design<br />
engineering, manufacturing, erection and commissioning.<br />
Irrespective of the OEM for the MSRs, we develop turnkey<br />
modernization solutions to extend the service life and raise<br />
efficiency. These are always established in close consultation with<br />
our customers.<br />

■ Perfected MSR technology based on decades of experience<br />
■ Original equipment manufacturer for the EPR (European<br />
Pressurized Water Reactor)<br />
■ Proven designs for vertical and horizontal MSR configurations<br />
■ Modernization by optimizing and replacing fine separators and<br />
reheater bundles<br />
■ Maximum component protection thanks to Powerseps installed<br />
upstream<br />
■ Excellent separation rates with considerable design reserves<br />
achieved with Powervanes<br />
■ All parts in contact with wet steam made of stainless steel to<br />
ensure erosion and corrosion protection<br />
■ Optimal compensation of all thermal expansion thanks to<br />
themoelastic connection systems<br />
■ Restrictive component dimensioning achieves vibration<br />
resistance
TECHNOLOGY<br />
MSR design is critical in view of its direct effect on plant availability.<br />
The MSRs are also subject to highly complex operating conditions<br />
on account of a corrosive two-phase flow on shell and tube side<br />
and considerable load variations.<br />
To cater for these special requirements, we attach great importance<br />
to our MSR design being based on conservative design criteria and<br />
combining both thermo-hydraulically and mechanically optimum<br />
properties:<br />
■ Powervanes ensure top separating rates with low pressure drop<br />
and high reliability against water carryover. Independent studies<br />
have demonstrated that this high-performance vane used in the<br />
fine separator is by far the most efficient one on the market.<br />
■ Perforated plates upstream and downstream of the fine<br />
separators ensure homogeneous flow profiles with constant<br />
separating efficiency locally. Deflectors also contribute to an<br />
even distribution and flow-through of steam.<br />
■ The fact that all components coming into contact with wet<br />
CFD analysis of a moisture separator<br />
steam are stainless steel or stainless steel clad means full<br />
protection against erosion and corrosion.<br />
■ Under all loads, flexible connection systems guarantee<br />
compensation of the different thermal expansions between<br />
vessel shell and reheater bundle as well as between reheater<br />
tubes and bundle structure.<br />
■ A high degree of vibration resistance is provided by numerous<br />
support plates arranged in the reheater bundle. The tube holes<br />
have rounded edges and tight drill-hole tolerances.<br />
■ Full accessibility to the interior for testing and maintenance<br />
purposes is provided by manholes and inspection openings.<br />
