Our original design called for the use of steam (medium-pressure steam) to feed the furnace tubes. Due to the instability of the medium-pressure steam available in the company, we want to add an additional supply of water for feeding the furnace tubes. We would like to ask whether the same control valve can be used for both steam and water supply, and whether the amount of water supplied should be the same as that of steam
Steam injection into the furnace tubes and water injection into the furnace tubes are two different methods of operation. Steam injection into the furnace tubes is used to control the temperature of these tubes by introducing medium-pressure steam, while water injection is used to control the humidity and temperature of the furnace tubes by adding water. In the original design, medium-pressure steam was used to inject steam into the furnace tubes; due to the instability of medium-pressure steam, it is possible to consider adding a water injection line for the furnace tubes as a solution to this problem. Water injection into the furnace tubes can be controlled via an injection control valve to regulate the water flow rate, thereby controlling the temperature and humidity of the coking furnace tubes. The same control valve can be used for steam injection into the furnace tubes and water injection into them, but adjustments and settings need to be made according to specific conditions. The water injection volume and the steam injection volume are not necessarily the same; the appropriate water injection volume must be determined based on the requirements of the coking furnace tubes and the process specifications. The setting of the water injection volume requires taking into account factors such as the temperature, humidity, and flow rate of the coking furnace tubes, and the optimal water injection volume must be determined through experiments and adjustments based on actual conditions. .
Is it confirmed that the role of injecting steam and water is to control the temperature of the furnace tubes?
