Both temperatures are related to the saturation temperature in the steam drum of a heat recovery steam generator. The approach temperature is the water temperature at the economizer outlet, which in many analyses is assumed to be equal to the saturation temperature for simplicity. The "pinch point temperature difference" is the difference between the saturation temperature and the gas temperature at the economizer inlet.

A "pinch" is just that... such as a pinch of salt in a recipe. I was told at one point that a Pinch works out to about 1/8th of a teaspoon, but it's probably even a little less than that. To do "a pinch of salt", one would pinch some salt between their fingers and put it in the recipe.
