ThermTech - Steam Boiler Economisers

A boiler economiser fitted to the flue exhaust of such a boiler will cool the flue gases down from 230°C to approximately 140°C while pressurised boiler feed water fed from the feed water pump is preheated from 80°C up to approximately 105°C before entering the boiler.

This means a reduction in fuel consumption of 4-6% for the same boiler output, resulting in a 6-18 month return on investment for the complete project installed and commissioned.

• Bespoke design to suit the individual boiler system
• Design conforms to BS EN 12952, the Pressure Equipment Directive (PED) and CE marked accordingly
• Manufactured entirely from carbon steel as the most economical design
• Highly durable extended surface fins spirally TIG welded around the outside of each boiler economiser tube
• Single tube design ensuring a uniform boiler feed water flow through the entire tube element even on a high boiler turn down, avoiding undesirable local hot spots, scaling and sludge build up inside the boiler economiser tubes
• Designed to minimise additional back pressure on the burner fan and additional load on the boiler feed pump at maximum boiler load such that normal boiler operation is not affected
