Glass-coating and cleaning system to prevent carbon deposition on coke oven walls

摘要

The new technology is described for protecting the coking chamber bricks from damaging by hard-pushing. The technology consists of the glass coating on the wall bricks and a wall cleaner to blow deposited carbon. For the glass coating, a specially developed glaze is sprayed onto the wall bricks by a newly developed spraying device to complete spraying one coking chamber in a few minutes. The wall cleaner installed on a pusher ram is the facility to automatically blow air at a sonic speed during coke pushing. The life of the glazed layer is estimated to be over two years.
