CISDI to build Hoa Phat’s green credentials with HRSG power generator

CISDI is assisting a Vietnamese steel plant to increase its green credentials.

It is to build a heat recovery steam generator (HRSG) power generator unit for Hải Dương Steel, which uses excessive heat from the coke oven to create electricity.

The HRSG is more protective of the environment. It can burn all by-products inside the coke oven to streamline production procedures, without the need of gas purification and chemical byproduct recovery.

It generates power from multiple boilers matching to one turbine to recover the COG fume’s excessive heat and plant-wide gas bled.

It’s clean and easy and generates a large amount of electricity. This is the first overseas application for CISDI.

Hải Dương Steel is part of Hoa Phat in Vietnam. The coke oven plant will produce 200,000 tonnes of coke a year and 380x10⁶ kWH electricity a year, creating cost savings of around $21.36 per tonne of liquid steel.

The power generator unit will contain the following hosts and auxiliary facilities:

s   Boilers: one 50t/h high-temperature ultra-high pressure HRSG (heat recovery steam generator) boiler and one 100t/h high-temperature ultra-high pressure gas-fired boiler

s   Generators: one 50MW high-temperature ultra-high pressure intermediate primary reheating condensing turbine and one 55MW generator and auxiliaries
