Fractal heat conduction model of semi-coke bed in …10/6/2020 · Coke dry quenching (two time heat transfer): the sensible energy of high temperature semi-cokes is recovered through two heat transfer processes in the coke dry quenching. Firstly, the sensible energy of semi-cokes is transferred to cold gas, then the sensible energy of hot gas will be absorbed by the boiler, as shown in Fig. 2 .The cooling chamber coke the coke dry cooling plantCoke dry cooling is carried out in coke drying chamber 1 by passing cooling agent through coke layer. Cooling agent circulation in said chamber is performed by circulation system 2 furnished with exhaust-heat boiler 3 and induced-draft fan 8 3 .

RU31381U1 - Dry coke quenching unit with continuous …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 power generated from the CDQ is environment-friendly and clean energy. In addition, compared with conventional wet quenching system, CDQ brings about advantages such as reduction of dust emission and improvement of coke …Research on Thermal Characteristics in Natural …Dry coke extinguishing installation with a continuous coke unloading device, comprising a quenching chamber connected to a closed loop, a dust precipitation hopper, a recovery boiler, dust collecting cyclones, a blower fan, a coke unloading device with a
