Heat exchanger design
Thread Content
The flue gas temperature is reduced from 640°C to 165°C. Water is heated from 140°C to a superheated state at 165°C under a pressure of 0.5 Mpa; the temperature of saturated steam is 152°C℃
Can steam be generated in a heat exchanger, saturated or superheated?
You need a drum to generate steam, which can be superheated, but there must be a superheating section. It involves using high-temperature flue gas to superheat the steam, while slightly cooler flue gas is used to generate saturated steam.
First, I use a heat exchanger to generate saturated steam, then use a drum to separate the wet steam from the dry saturated steam, and finally superheat it to become superheated steam, is that correct?
What is generated by the heat exchanger is actually a mixture of water vapor, which is separated in the drum.
Is there a phase change in the calculation process, and does it need to be calculated in three stages?
Can a heat exchanger realize the owner’s idea?
For my graduation project, I need to design a waste heat boiler. I majored in process control, and waste heat boilers also fall under the category of heat exchangers; surely I’m not expected to use boiler design methods for this task
Since there is no pressure in the flue gas, should the heat be calculated using water or the flue gas?
