The thermal convection tank

The Thermal Convection Tank (Figure 13-22).

■ Can be pressurized or un-pressurized.

■ Conducts a re-circulated flow by thermal convection. When enough heat is generated inside the mechanical seal, it expands initiating a flow into the tank where it cools and contracts and is brought again into the seal.

■ The tank is sealed and welded, and meets the boiler code for pressure vessels.

■ Has a specific location in relation to the seal to optimize the convcctivc flow.
