LLT awarded multiple boiler contract for Lyonnais biomass heat project

France-headed thermal energy system provider Leroux & Lotz Technologies (LLT) has announced that it has received an order from Dalkia Centre Est for two biomass 'chute to stack" boiler islands for a greenfield heating project in Lyon, France.

According to a statement, Metropole de Lyon decided in 2015 outsource the public services for the operation and maintenance of the district heating (DH) network in Lyon, Villeurbanne and Bron for a 25 year period. The tender which included an overall renovation and extension programme of the network was won by Dalkia Centre Est.

Part of the programme was to create a greenfield district heating facility located in the 8th district of Lyon and close to the Hôpital Saint-Jean de Dieu and known as the SURVILLE Heating Plant. When completed the facility will consist of three 18 MW biomass-fired heating plants and four gas-fired boilers.

Leroux & Lotz Technologies (LLT) was awarded the biomass scope contract by Dalkia Centre Est after a tendering process. The implementation plan is staged and the contract includes the supply and commissioning of two 18 MW biomass boilers with an optional third 18 MW boiler by 2019.

The boilers will produce high-pressure hot water (aka superheated water) and the ‘chute to stack’ scope consist each of a bubbling fluidised bed (BFB) combustion system with hybrid boiler design of a water tube membrane wall furnace and fire tube heat exchanger section.
