Hot Oil Expansion Tank

Second the expansion tank provides a mechanism for venting water incondensibles degradation by products and entrained air during startup and operation.

Hot oil expansion tank. 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. Thermal fluid expansion tanks and degassing systems are important for maintaining long oil life as well as lowering the maintenance costs on the thermal oil heater pumps and process equipment. Expansion tank size calculator. First the expansion tank serves as the safe outlet for the increase in thermal fluid volume due to thermal expansion.

Thermal process development can provide an expansion tank degassing tank system or help design a complete new system. This water heater expansion tank stops hot water from backflowing into the cold water line and prevents hot water from escaping through the pressure relief valve and onto the floor. The ideal height for the expansion tank is above the highest liquid level in the system. Constant fluctuations in water pressure can be dangerous and they can damage the water heater properly installing a thermal expansion tank can solve all these issues.

All water heaters regardless of whether they use heating oil natural gas or propane or even electricity can suffer the negative effects of thermal expansion as the cold water coming into the tank turns to hot heated water increasing the overall water volume via expansion and increasing pressure inside the tank. It also helps in removal of moisture and non condensables during start up. This article will show how to do sizing of an expansion tank. The pirobloc de 2500 v hp expansion tank is a reservoir suitable for being pressurized with a diaphragm dividing the tank into two parts air and fluid.

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. Expansion tank is provided in hot oil system to accommodate for the increased thermic fluid volume due to thermal expansion.

Volume expansion is considered as difference between specific volume m3 kg i e. Inverse of specific gravity of hot oil at maximum and minimum operating temperature of the system which is required to be accommodated between low liquid level and high liquid level of expansion tank. Expansion tanks are occasionally full of hot thermal oil making them both burn and fire hazards.
