CISDI has created an innovative dual fuel solution for a 120-tonne-per-hour reheating furnace at Vietnam’s Dung Quất Steel Joint Stock Company.

The dual-fuel solution is a major feature of Dung Quất Steel Joint Stock Company’s full-process steel plant in Vitenam's Ouang-ngai Province. The Hoa Phat Group have invested $2.5 billion in the plant.

To improve reheating quality and bring about cost savings by reducing energy, LOI and emissions, CISDI created dual-fuel regenerative burners, evaporative cooling, combustion control and a number of other core technologies.

An optimum combustion system has been tailored to utilise different fuel supplies at various production stages. Blast furnace gas is used when available, and liquefied petroleum gas kicks in at other times.

CISDI’s combustion solution works automatically and does not require modification to switchover fuels and has been highly praised by Dung Quất Steel and the Hoa Phat Group.

The furnace was built by CISDI Thermal & Environmental Engineering on an EPC basis and has now been dried off and has entered its hot commissioning stage.
