ENVIRONMENTAL AND TECHNOLOGICAL ASPECTS IN THE PROCESS OF DIRECT AND INDIRECT COOLING OF COKE OVEN GAS
Abstract
The article analyzes the experience of operation and methods of cooling of coke oven gas. The advantages and disadvantages of direct and indirect cooling methods are described. Intensification of heat transfer is achieved by the removal of deposits on heat transfer surfaces. The ways to eliminate pollution caused by organic deposits of coke oven gas are shown. Operating costs for maintenance of the primary gas coolers are directly dependent on the quality of cooling water. The practical experience is described how to reduce the negative impact of the circulating water in the cooling efficiency of the coke oven gas.Key words: direct and indirect cooling, coke oven gas, heat transfer equipment, cooling water.
