What is the difference of pressurized gas tank to compression tank?4 answersA pressurized gas tank typically maintains pressure using a secondary fluid or a flexible bladder to exert pressure on the primary fluid. On the other hand, a compression tank, like a heatable compression type high-pressure gas tank, utilizes a flexible sealing part that allows the tank body to change capacity by sliding, effectively reducing the tank's volume to increase internal pressure. Additionally, a pressurized tank for conveying powder features check valves and an elastic body to prevent air flow back from the piping, ensuring controlled powder feeding. These differences highlight how pressurized gas tanks focus on maintaining pressure through secondary fluids, while compression tanks adjust capacity to enhance pressure and functionality.
What are the factors that affect the performance of gas turbines?4 answersThe performance of gas turbines is affected by several factors.
