Complete Service, Repair and Upgrade

Waste heat usually released up through the exhaust and into the atmosphere can be captured and utilised to maximise the energy potential of your plant through retrofitting a heat recovery system. For systems which already have this capability incorporated into them, Avantis can offer complete design, service, repair and upgrade solutions to all types of Heat Recovery Steam Generators (HRSG) and Waste Heat Recovery Units (WHRU).

We also offer inventive solutions to capture the waste heat from auxiliary engines installed on ships by designing and manufacturing class approved Exhaust Gas Economisers (EGE) and Exhaust Gas Boilers (EGB), which depending on the configuration mean that the auxiliary boiler on board will become almost redundant.

Heat Recovery Systems - HRSG & WHRU in Detail

Heat Recovery Steam Generator (H.R.S.G.)

A heat recovery steam generator is plant which recovers heat from a gas stream to generate useable steam, with the most common application being from a gas turbine. The steam produced can be used for process purposes or for driving a steam turbine to produce electrical power, known as cogeneration and combined cycle respectively.

HRSGs can be supplied in a modular arrangement with evaporator, economiser and superheater elements, a packaged assembly with a water cooled furnace, or in a once through design, where the inlet feedwater flows in a continuous path without segmented sections for economizers, evaporators, and superheaters. HRSGs can be installed with supplementary burners known as duct burners, to increase the steam output.

Waste Heat Recovery Unit (W.H.R.U.)

A waste heat recovery unit is similar in principle to a HRSG in that it is heat recovery plant, installed in the exhaust heat generating plant, but the main differentiator being that WHRU’s are used to increase the efficiency of an existing plant (cogeneration) and is not the sole or primary steam generator.

WHRU units come in various designs for different applications. An economiser installed in a boiler to increase the feedwater temperature is a form of waste heat recovery. A common marine application is an Exhaust Gas Boiler (EGB), which generates steam from the waste heat coming from the ship’s main engine, or Exhaust Gas Economiser (EGE) installed into the uptake of the auxiliary engine and used to provide a hot water steam mix directly to the vessel’s auxiliary boiler.
