Where is Watt's improved steam engine better than before?

Newcomen's steam engine consumes a lot of coal and has low efficiency. Using scientific theory, Watt gradually discovered the faults of this steam engine. From 1765 to 1790, he made a series of inventions, such as separate condenser, cylinder external insulation layer, piston lubricated with oil, planetary gear, parallel linkage mechanism, centrifugal governor, throttle valve, pressure gauge and so on. , make the efficiency of the steam engine to more than three times that of the original newcomen machine, and finally invented the modern steam engine.
