Heat Recovery Economisers
Efficient economiser units use waste industrial and flue gas heat exchange to produce energy to preheat boilers
We will reduce heat wastage from your industrial flue gas with heat recovery economisers produced in-house to your exact requirements. Efficiently turn waste industrial heat into a useful energy source for water heating, process or space heating, or generating power.Read more >
Installation of economiser units within your exhaust system stack can greatly reduce the exhaust temperatures. Heat recovery usefully reuses the energy wasted within the flue and often improves overall energy efficiency by around 5%. Contact us for a project calculation.
How does an industrial boiler heat economiser work?
- An extended-surface finned tube heat exchanger is fitted inside an exhaust flue.
- The heat exchanger absorbs the heat from exhaust gases.
- This energy is used to heat the water in a water pipe system, for example for heating water being fed into a boiler.
This is a highly effective way of pre-heating boiler feed water: as an example an all-steel economiser battery for a 5,000 kg/hr steam boiler can pre-heat boiler feed water from 85ºC to 120ºC using exhaust flue gas at 210ºC.
Economiser heat exchangers mean greener energy efficiency
Heat recovery improves efficiency in your industrial plant’s activities; this results in a reduction in overall pollution and carbon footprint and reduces your overall costs in the long term as your fuel consumption is cut. Installing and maintaining stack economisers that are customised to optimise your system we look to:
