Greens have been at the forefront of Waste Heat Recovery since Edward Green first invented the fuel Economiser in 1845.

Greens specialise in the recovery of Waste Heat from boiler & process flue gas streams in the Power Generation, Refining, Chemical, Process and general industries.

Greens Economisers are individually designed to client's requirements, for operation with a wide range of fuels and process / waste gases. Greens Economisers operate with super critical power boilers of 1000 MW rating, to small industrial applications with rating of 5 tonne / hr approx.

Power Station Economisers
Greens Economisers operate with large utility super critical power boilers, ranging from 100 MW - 1000 MW.

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

Fuel Range
• Coal
• Lignite
• Biomass (wood, bagasse, straw, rice husks, etc)
• Heavy Fuel oils, Asphalt
• Cement, Garbage, Sulphuric Acid gas streams
• Natural Gas, Blast furnace gas

Greens Economisers are installed by the world's leading boiler makers, including IHI, Babcock Hitachi, Alstom Energy, MHI, L.C.Steinmuller, Mitsui Babcock, Kvaerner Pulping, FLS Miljo, Stork Ketels.

On industrial boiler applications, Greens economisers combine compactness and high performance to achieve enhanced fuel savings within limited installation space and differing operating conditions. Greens manufacture a range of finned tube profiles & types to suit the varying waste gas constituents. Steel 'H' finned tubes (Single /Double) are ideally suited for flue gases containing dust; they provide high efficiency and low fouling characteristics.
