Greens Industrial Economisers are designed to operate with both shell package type and water tube boilers. The economic range starts at 5 Tonne/Hour.

An Economiser is a Money Saver for operators of industrial boiler and furnace plant, helping make the most of valuable primary energy.

Why Greens Power
TEi - Greens have more practical experience in Economisers than any other company. It was Edward Green, the company’s founder who invented the original economiser in 1845. The units in production today are the result of an unbroken history of practical development and a thorough understanding of industrial users.

Financial Benefits
The annual fuel bill for a typical industrial boiler plant will far exceed its original capital cost. Clearly every 1% saving is of great and increasing significance.
Generally 6% of the fuel bill can be saved by an economiser even on efficient modern packaged boiler plant. A Greens Power Economiser, individually designed to suit your particular requirements will produce these savings year in - year out and will require very little routine maintenance.

Operational Benefits

Easier Steaming
By using heated feedwater, the boiler reacts more readily to loads.

Longer Boiler Life
Heated feedwater substantially reduces ‘racking stresses’ caused by relatively cold water entering the hot boiler. The economiser protects the boiler from these thermal stresses and helps to prolong the service life of the boiler.

Increased Steam Capacity
Where required an economiser can be used to increase the steam production above previous maximum outputs.

The Right Heating Surface
Greens Power have developed over the years several different types of extended surface tube to suit many fuel types, maximising thermal efficiency and low fouling characteristics.
