Performance, Reliability and Emissions Reduction in Waste Incinerators.
The Mission of the PREWIN European Network is to support progress towards improved performance and reliability of European Waste-to-Energy plants (incineration and co-incineration) while maintaining low or reduced emissions to the environment.
What is being organised?
Twice a year there will be held a meeting at an interesting location in Europe. A plant visit is always part of the meeting, which typically is joined by 140+ participants. During this one and a half day, members of the network or guest speakers will present their experiences on a specific topic.
The main areas for future meetings are based upon questionnaires which roughly once in three years is distributed under the participants. Some of the topics of the last years were.
- High-efficiency Waste–to-Energy plants
- Corrosion and Materials
- Plant condition/emission monitoring methods
- Better materials and better informed selection of materials for critical applications
Examples of meeting agendas can be found here:
At the meeting in Prague, June 2016, results were presented of a benchmark study on the availability of WtE plants. Data from 208 lines processing 2750 tonnes of waste per hour has been gathered. Results from availability, unplanned outage and overall equipment effectiveness are available. Further it shows clearly different maintenance strategies (time between planned stops and length of planned).
In spring 2019 this survey has been updated. Data from 248 lines were collected. Results from availability, unplanned outage , length of stops are available as function of e.g. capacity, thermal load.
In 2017 a survey on maintenance costs was conducted. The results were shared among the operators who completed the survey.
Unplanned shutdown classification
In 2018 a survey on unplanned shutdown classification was conducted. The results were shared among the operators who completed the survey.
A maintenance working group has been created. This working group which comprises maintenance engineers from operators is exchanging experiences during one day workshop meetings. The working group gathers twice per year.
