Up-Tube Heat Exchanger Engineering Design and Heat Transfer Analysis

In the coking process, a large amount of 750℃-800℃ coke-oven gas is produced, and the traditional process is to use circulating water spray to cool the coke-oven gas instantly to 80-90℃, and the sensible heat of the coke-oven gas is wasted. In order to recover sensible heat of coke-oven gas reliably and stably, this paper puts forward a kind of uptube heat exchanger for sensible heat recovery of coke-oven gas based on the problems existing in the past heat exchanger and the characteristics of coke-oven gas itself, and analyzes the heat transfer process equation of heat exchanger.
