No, equal TNT power equivalent can have different effect depending on the nature of the explosive. The heat spreaded from an amonium nitrate blast, like in Beyrut, does not last as long, from [0],

> However even on this basis, comparing the actual energy yields of a large nuclear device and an explosion of TNT can be slightly inaccurate. Small TNT explosions, especially in the open, don't tend to burn the carbon-particle and hydrocarbon products of the explosion. Gas-expansion and pressure-change effects tend to "freeze" the burn rapidly. A large open explosion of TNT may maintain fireball temperatures high enough so that some of those products do burn up with atmospheric oxygen [...]
