In moderation it's ok, but It is generally not recommended to put ash from wood into a home composting bin.
Ash from wood can contain high levels of potassium and other minerals that can inhibit the growth of microorganisms in the compost and slow down the decomposition process.
In addition, ash from wood can also contain small amounts of unburned carbon, which can cause the compost to become too alkaline and reduce its ability to support the growth of beneficial microorganisms.
