The modernizing flue gas treatment at the Bayet incineration plant

Overview

As part of its new public service contract for operating the Bayet incinceration plant in central France, Lucane, a subsidiary of Veolia, intends to carry out modernization work to improve its energy performance:

– Updating the flue gas treatment system (switching to dry processing)

– Implementing further heat recovery from the fumes

Bayet manages around 55,000 tons of household waste annually and is the only plant to process hospital waste in the Allier area, which puts considerable pressure on availability.

Assignment

This modernisation project mainly involves:

- Implementing a dry processing system, with a storage/mixing system, radiant heat transport shafts and updated regulation

- Stopping the scrubbers also implies updating the downstream equipment: chimney, shafts and analysers

- Introducing flue-gas energy recovery to preheat feed water

setec is assisting Veolia in the following areas:

- Validating and updating the feasibility study

- Drafting bid documents (excluding administrative documents) for three packages: analysers, processes and dismantling

- Following up the bid process, analysing candidates and conducting negotiations

- Following up construction design work

- Supervising construction work

- Monitoring comissioning and performance testing
