Abstract: The new application of the waste heat recovery technology in the ascension pipe of the coke oven battery will make the steam production in the coking plant larger than its consumption, on the basis of the existing CDQ waste heat recovery. After comparing the incomes, investments, energy efficiency and land occupation of different steam utilization schemes, it is found that the direct sale of steam is the best option; if not possible, a turbine power station is recommended.
