Waste Heat Recovery Boiler

Isotex superefficient Waste Heat Recovery Systems find ideal applications in Cogeneration Systems working on Reciprocating Engines and Gas Turbines. Engine flue gases contain 30 - 40% of heat generated by burning diesel/F.O. etc. Most of this energy can be recovered by installing one of our specially designed Retromiser waste heat boiler.

Various sources of waste heat:

Exhaust heat recovery from Reciprocating Engine driven Gen-sets used for Captive Power Cogeneration and independent power production.
- Heavy fuel oil Fired
- Gas Fired
- Diesel Fired
Exhaust heat recovery from Gas Turbine exhaust
Jacket heat recovery from Engine

Isotex offers RETROMISER XF series Heat Recovery Boilers to recover this ’waste’ heat and convert it into a useful form such as steam or hot water which can be used for a wide variety of process heating and sometimes cooling applications. Smoke tube composite type-exhaust gas and oil fired boiler as per requirement. The range of heat recovery boilers goes up to 20 t/h with or without post-combustion.

These heat recovery boilers are horizontal (on request vertical) shell and tube type and are used for the production of steam from the flue gas coming from gas turbines, diesel or gas engine, VOC Thermal Oxidisers and any source of hot gas effluent in general. This range of equipment is available in standard design from 500 kg/hr, pressure 10.54 kg/cm²g to 16t/h and 25 bar. The gas on standard design is for up to 1000°C. The design provides a large steam volume, optimises the heat-transfer surface and the quality of the produced steam. This equipment is entirely constructed in Isotex factories and ready for online installation.

Air pollution control and the production of emissions are on everyone's tongue since the discussions about the climate have started up again. Air pollutants such as carbon monoxide, fine dust, soot, sulphur dioxide or nitrogen oxide have to be avoided or kept to a minimum.
