Coke Dry Quenching (CDQ) System | NIPPON STEEL ENGINEERING

CDQ is a heat recovery system to cool the hot coke from coke ovens. It is one of the most renowned energy-efficient and environmentally-friendly facilities within steel production. CDQ is a system where hot coke removed from coke ovens at a temperature of approximately 1,000°C is cooled and kept dry with inert gas and the resulting steam produced in a waste heat recovery boiler is used to generate electricity.

INTRODUCTION OF CURRENT TECHNOLOGIES FOR COKE …

CDQ is a system to cool the hot coke brought out of coke ovens at a temperature of about 1,000 °C with inert gas and generate electric power by steam produced in the waste heat recovery boiler. Since the sensible heat recovered by the heat exchange in the cooling chamber is utilized as the heat resource for the steam generation, electric

Should you get a heat pump? Here's how they compare to a

Mar 26, 2021 · Given the high initial costs and the limited heating output of a heat pump, having a gas boiler might prove to be cheaper and to a certain extent more efficient, especially during the cold days of the winter, when you might need a higher heat yield. Considering, the continuous improvement of heat pumps, we might expect that in the near future these will increase their performance rate, and therefore will set higher efficiency standards that will be hard to match by other heating …

waste heat boiler of dry quenching – Horizontal Coal Fired

The coke dry quenching equipment broadly consists of a coke cooling tower (pre-chamber and cooling chamber) and a waste heat recovery boiler. The entire process has as follows: Red-hot coke (approx. 1,200°C) is charged into the coke cooling tower, and inert gas is blown into the tower from the bottom.

A Study of Waste Heat Recovery Boiler Operation and

Dry quenching method saves water (around 0.5–1.0 m 3 per ton of gross coke); reduced water pollution as well gives opportunity for waste heat recovery. Stable coke quality and energy efficiency of the process are key driving forces for this technology. Experience with dry quenching in USSR indicated that it improves coke strength by increasing M40 index and by lowering M10 index.
