What does one kilocalorie (th)/second represent?

It represents a rate of heat transfer equal to one thermochemical kilocalorie per second, exactly 4184 watts.

Why convert to calorie (IT)/hour units?

Calorie (IT)/hour units express very small steady heat flow rates and are useful in detailed calorimetric analysis and technical documentation.

Are kilocalorie (th)/second and calorie (IT)/hour directly comparable?

They measure power at very different scales and use different calorie definitions, so conversions yield large values and require careful interpretation.
