Hot-storage tanks (TANK)Heat loss and heating of hot-storage tanksTANK module package Fundamentals:Storage tanks might have to be heated to compensate for the cooler climatic conditions of the environ-ment. In order to determine the required heat duty it is necessary to calculate the various types of heat loss from the surfaces of the tank. |
TANK calculates the heat losses of insulated and heated storage tanks. The floor plan of the tank might be round, rectangular or arbitrary.
The heat losses through the bottom to the ground, through the wetted wall, through the dry wall or through te roof are determined separately. The program determines also the inner convection flow for the heat loss through the wetted wall to the environment.
If the gas above the liquid is air, the properties are determined automatically. For other gases, the proper-ties can be entered.
The heating is accomplished either by a pipe coil or tube bundle located inside the tank or by welded or otherwise attached pipe coils or tube bundles outside the tank.
The TANK module package performs the calculations by using specialised modules. A quick result is achieved with only few input values.
The calculations are based on the LV Heat Atlas approaches for heat transfer, free convection, etc.
