摘　　要：焦炉上升管荒煤气带出热量占焦炉支出总热量的36%,增设荒煤气显热回收系统是实现热能回收,降低能源消耗、碳排放和生产成本的有效措施。荒煤气显热回收系统采用外置双曲线螺旋管换热器与强制、自然双循环系统相结合的工艺技术,可在保证安全的基础上,最大程度回收荒煤气显热。The heat brought out by the raw gas from the riser of the coke oven ac-counts for 36%of the total heat of the coke oven expenditures,and the addition of the raw gas sensible heat recovery system is an effective measure to realize the recovery of heat en-ergy and reduce the energy consumption,carbon emission and production cost.Raw gas sen-sible heat recovery system adopts the technology of combining external hyperbolic spiral tube heat exchanger with forced and natural dual-cycle system,which can maximize the re-covery of raw gas sensible heat on the basis of ensuring safety.
