I did not find information about how does work the process of burning 90% commission coins. At the time of writing this post, the number of coins burned is 47 694.46250556 BGL. Where are these coins stored? I didn't find an address with such a coin balance...
On the first post it's stated
Block Reward = nFees*0.1 + GetBlockSubsidy()
it means that block reward (which is composed of coinbase tx for mining and sum of tx fees.
The burn is implemented in the code, it is not by transfer to some burning address, it's in the core logic itself (validation.cpp
https://github.com/wu-emma/bitgesell/blob/64c24348f1ba8788fbffaf663b3df38d9b49a5d1/src/validation.cpp#L2161), you can check fees in a block and see that reward is 0.1 of those, so 0.9 are burned forever.
