Hot Oil Expansion Tank Elevation
Hi dears i shall design a hot oil system.
Hot oil expansion tank elevation. The key concepts are. Volume expansion is considered as difference between specific volume m3 kg i e. Its main purpose is to allow some place for the heat transfer fluid when heated to expand into and when cooled a source to draw fluid from to keep the system full. Pressurizing the air side of the tank to equal the static pressure of the water at the expansion tank location and before adding water to the system.
The vessel should be elevated so that the normal operating level of the heat transfer fluid htf in the vessel is higher than the highest possible htf level in the system. Expansion tank size calculator. 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. This tank is critical to the operation of the system.
Free shipping on orders over 99 we only ship within the united states. Expansion tanks are occasionally full of hot thermal oil making them both burn and fire hazards. My system includes a heater with vertical radiat section and horizontal convection section do you know how shall elevation of hot oil expansion vessel be selected is it required that hot oil expansion tank located in highest point of system convection setion or it can be possible to. Thermic fluid density is 1056 kg m at 30 c and 761 kg m at 350 c.
The hot oil system expansion vessel or surge drum should be connected to the system return line on the pump suction side. L d to be used as 2 5. 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. The ideal height for the expansion tank is above the highest liquid level in the system.
Fluid is heated from 30 c to 350 c. Hot oil expansion drum calculation. It is also a built in reserve tank for your system just in case. A detailed procedure for sizing diaphragm type expansion tanks is given in reference 1 as well as several other industry publications.
The final component of a hot oil system is the expansion tank. To the hot oil storage tank or into main s ystem itself in case hot oil. Head of the pump is estimated based on the elevation of the expansion vessel. For product availability in your area please verify your zip code.
Myth 3 an open top drum makes a great catch tank. System hot oil volume is 7 87 m. Inverse of specific gravity of hot oil at maximum and minimum operating temperature of the. A minimum volume 10 20 is considered in expansion tank at start up in cold.
This seems like a good idea until the heater room suddenly fills with smoke or worse.
