Elga Process Water is helping Veolia Environmental Services to maximise the efficiency of its boilers at the Tyseley energy recovery facility.

Veolia required a specialist conditioning chemical supplier for the boiler water at its facility, which incinerates 350,000 tonnes of Birmingham’s non-recyclable rubbish each year and exports 25MW of electricity to the National Grid to power more than 41,000 homes.

The facility has two 45bar 400C water tube boilers delivering 67 tonnes per hour of steam to the high-pressure turbines.

It also has a 10bar waste-heat shell boiler fuelled by a clinical waste incinerator; this supplies steam to a low-pressure turbine.

In order to maximise boiler efficiency, the quality of the water fed to the boilers has to be carefully controlled.

Tyseley produces high-purity deionised water on site and adds chemicals to scavenge oxygen and adjust the pH to prevent corrosion.

The combination of the two types of boiler with common feed water and condensate systems means that controlling the boiler water chemistry requires a specialist solution.

Elga Process Water, a Veolia Water Solutions and Technologies company, carried out a detailed site survey with technical support from its Boiler Competence Centre.

A solution was developed that included the appropriate chemicals from its Hydrex range to protect the boilers, turbines and condensate system, as well as providing recommendations for regular service support to maintain boiler efficiency and optimal performance.
