> Information on Casing Components of KSB Boiler Circulating Pumps Type LUV <
Sometime ago KSB AG had already informed power plant owners that fatigue cracks might occur on casing components of boiler circulating pumps type LUV. Primarily pump casings and thermal barriers might be concerned. On some casings indications of cracks were detected by non-destructive testing which resulted e.g. from material fatigue pending on decades of pump operating times and changed mode of operation, especially due to grid feed-in of regenerative energy.

> List of New Power Plants in Europe: Update February 2014 <
The list New Power Plants comprises power plants in planning and under construction in Europe. Energy sources like gas, hard coal, lignite, wind, water, waste etc. are considered. Based on the list, the planned total output (MW) and the portions of the sources of energy (MW) can be determined.
The current list is available in myVGB for download:

> BREF-LCP Process <
End of 2013 over 8,500 comments to the first draft were introduced by the members of the Technical Working Group (TWG). Although many associations and member states have called for the submission of a second draft, EIPPC office and European Commission refused to do so due to the tight time frame and other starting BREF revisions. Also support from the TWG by the formation of subgroups, which should work out specific issues, is refused from EIPPC office. Instead, an interim meeting of the TWG takes place on June 17-18, 2014, where the following topics will be discussed: EIPPC office will continue with the detailed assessment of the major comments and will release background papers (revised chapters of the D1) in time before the scheduled final meeting of the TWG at the end of the year.

1) Call for Assistance in the Revision of European Test Standards for Fly Ash for Concrete EN 451 Parts 1 and 2

At its last meeting on March 6/7, 2014, CEN Technical Committee 104 for concrete decided to revise the standards with test methods for fly ash for determination of
- free calcium oxide content (EN451-1) and
- fineness by wet sieving
editorially and technically. Working Group 4 of TC 104 will prepare and discuss the revised standards at its next meeting in September 2014. The standards will be voted by CEN member states in early 2015.

In their comments for the revision especially of EN 451-1 the power power plant operators by majority asked for a more detailed process description, the implementation of alternative procedures for end point determination, the reduction of the cooking time from 3 to 1 h and the implementation of the free lime determination by conductometric analysis.
As background information for the reduction of the cooking time the results of comparative analysis have to be compiled and introduced to the WG 4. In the same way the results of comparative testing by conductometry (correlation data) have to be prepared.

We therefore ask all laboratories and test centres to assist the revision work and to provide their results.

2) Fire and Explosion Protection in Biomass Power Plants - VGB-S-018-00-2013-12-EN

The VGB-Standard "Fire and Explosion Protection in Biomass Power Plants" presents methods of using operational and adapted technical measures to keep the risks of fire and explosion as low as possible. In this way, potential hazards can be avoided by the deployment of suitable operational workflows. Fires can be detected without delay and combatted effectively under the specific conditions of the type of plant concerned. The formation of potentially explosive atmospheres can be limited by operational and technical measures.
