Hot Oil Expansion Tank Design
In case hot oil storage tank is not in the scope of the project the sump pump can be.
Hot oil expansion tank design. This can be system piping the heater or sometimes the thermal fluid space within a user for instance the heat exchanger calendar roll or press platen. Hot oil sump pump is a vertical submersibl e 1 x 100 centrifugal pump placed insi de the hot oil drain drum. Expansion tanks our expansion tanks are designed and manufactured under both the ad merkblätter design code and asme section viii division i u stamp. Designing building and operating a thermal oil heat transfer system can be cost effective if planned for properly from the start.
Myth 3 an open top drum makes a great catch tank. To remove particulate from the system some systems have in line or side stream preferred method filtration units. Plan thermal fluid system layout carefully there are an infinite number of layouts and that is because. This article will show how to do sizing of an expansion tank.
Expansion tank is provided in hot oil system to accommodate for the increased thermic fluid volume due to thermal expansion. There is an expansion tank on the system to allow for the expansion of the hot oil as it gets heated up and contraction when the hot oil is cooled down. Thermal process development hot oil heaters standard design use a dual helical coil layout which has two fluid passes through the hot flue gases. The ideal height for the expansion tank is above the highest liquid level in the system.
The expansion tank is usually elevated so that the normal operating level of the hot oil in the vessel is higher than the highest possible hot oil level in the system. This seems like a good idea until the heater room suddenly fills with smoke or worse. Expansion tanks are occasionally full of hot thermal oil making them both burn and fire hazards. First the expansion tank serves as the safe outlet for the increase in thermal fluid volume due to thermal expansion.
The dual helical coil design provides the highest heat transfer efficiency for hot oil heaters. Starting with common design layouts and continuing through operations cleaning and troubleshooting these 10 tips will help you maximize your investment. Every thermal fluid heater installed inside a building requires a catch tank to collect the discharges of the expansion tank vent and system relief valves.
