Waste Heat Recovery & Economisers | Turnbull & Scott
By capturing the waste heat in the flue gas with an economiser and diverting it to pre-heat the steam boiler feed water, the boiler thermal efficiency can be increased to as much as 95%. Improving thermal efficiency cuts fuel consumption resulting in significant cost savings often in the region of 4-6% p.a.

Economizer Functions In Boiler System,Economizer for high efficiency industrial-ZBG Boiler
Boiler economizers reuse exhausted flue gas to pre-heat the feedwater entering the boiler. Essentially a mini-heat exchanger, economizers improve boiler performance while increasing fuel efficiency. By rapidly increasing feedwater temperature through captured flue gas, economizers also provide a significant improvement in steam generation and response time.
