Title: Quenching track shed
Inventor: HAASE DIETRICH DR ING
IPC: C10B33/00
Filed: 1981-04-16
Abstract: For the removal of gaseous and ground-level emissions which result on pushing the coke produced in horizontal-chamber coke ovens, quenching track sheds are used which cover the entire coke oven battery on the quenching track side. Early deposition of the extracted dust is prevented by baffles of flow-promoting design underneath the actual roof of the quenching track shed, the roof space as a whole being subdivided into individual cells. The remaining space underneath the quenching track shed can be supplied with fresh air in an optimal manner by associating the coke guide with guide walls which are designed to come down to the upper edge of the quenching car and up to the partitions forming cells. In this way, the region connected to the extraction device is restricted even in this area, while the remaining area underneath the quenching track shed is always freely accessible for ventilation.
