Thermal stability Clause Samples

Thermal stability. The thermal stability of an oil is a measure of its ability to resist breaking down when heated to form deposits of resins and sludge. This can occur in the fuel nozzle area and in fuel heaters especially if the heater surface is far hotter than the surrounding oil. This polymerization to form deposits is a time--temperature phenomenon: being accelerated by high temperatures, long exposure times and contact with air. Thermal stability is most critical for high viscosity residual fuels which require high temperatures to meet fuel atomization viscosity requirements. The maximum allowable temperature specified is 275(Degree)F (135(Degree)C).

Thermal stability. The Accelerated Rate Calorimeter EV ARC from THT, see Figure 8, will be used for the thermal abuse tests, in order to determine the temperature at which the cell becomes unsafe. The tests will be performed on cells previously fully charged, according to a standard charging procedure defined by the Partner in charge of the cell manufacturing. Figure 8: Photographs of the calorimeters used at CEA to perform thermal runaway tests Thermal runaway tests will be performed in a pseudo-adiabatic calorimeter, following the “Heat-Wait-Seek” protocol: from an ambient temperature called start temperature, the temperature is raised for a given temperature step, then stabilized until an exothermal reaction of the cell is detected in less than 30 minutes. If not, a new temperature step is done. An exothermal reaction is considered when self-heating is higher than the temperature rate sensitivity measured at skin level. When detected, this temperature level is recorded and called the onset temperature. Then, the temperature keeps on rising until the end temperature threshold is reached, or if the maximum temperature rise criterion called end temperature rate is reached. The Figure 9 below gives an illustration of the process: The setup proposed for ASTRABAT project is:  Start temperature: 30°C  Temperature step: 5°C  Temperature rate sensitivity: >0.02°C/min. = thermal runaway  End temperature: 200°C  test stop  End temperature rate: 3°C/min.  test stop Annex: EUCAR Hazard levels

Thermal stability. Diesel Fuel is increasingly used as a coolant for high-pressure fuel injection systems that can thermally stress the fuel. In some cases, this stress can cause the fuel to degrade and form insoluble materials that can restrict fuel flow through filters and injection systems.
