Steam pressure issues in coal chemical industry
Thread Content
Why isn’t the steam pressure used in coal chemical industries very high? Is there a trend toward increasing this steam pressure? People from design firms say that high-temperature, high-pressure boilers have high initial costs, but lower operating costs later on. Could someone please provide a brief explanation? Thank you
It is mainly based on the requirements for steam quality in coal chemical production processes as well as the overall balance design of the steam network
High-temperature and high-pressure steam: 1. It can reduce the pressure loss in power transmission, 2. It can improve the efficiency of heat utilization.
Production capacity is a major limiting factor
What was said on the 2nd floor is correct. Although high-temperature and high-pressure steam has excellent thermal potential, it needs to be considered comprehensively for each process. A pinch analysis of the entire plant is required to achieve optimal energy utilization, thereby saving energy and improving efficiency.
It is mainly determined based on one’s own manufacturing process
The steam pressure in coal chemical industry should be determined by the process, right? Is it also related to the choice of engine?
If steam at a higher pressure is required, it can be produced; this is still determined from a process perspective.
