Two different parallel watt density cables may be spliced together. Being parallel, the power out put in the two spliced sections will be different as rated. Care must be taken to not exceed the maximum circuit length and circuit breaker rating. The simple solution in this case is to use the maximum circuit length of the higher wattage cable.

While thermal insulations have thermal conductivities, or k-factors, that reduce the flow of heat, the k-factors vary depending on the specific thermal insulation type. They also have different maximum temperature ratings. These factors must be addressed in a heat tracing design.

Typically not. Heat tracing is primarily used for temperature maintenance. Heat-ups in short periods of time (minutes to a few hours) will most likely require more heat than that needed to maintain the temperature at the desired temperature above ambient.

For accurate SO2 measurement a testo fluegas analyser must always be equipped with a SO2 and NO2 cell. NO2 has a negative impact on the SO2 reading by 110%. If the analyser measures NO2, it will automatically compensate for this. If not, then the SO2 reading might be far out depending on NO2 in the flue gas.
