Let's draw some Atari ST bombs!
Jelly, 43 44 bytes

+1 byte - forgot to double the characters (not that anyone noticed!)

How?

Preparation was to compress the data as a run-length encoding of the original image:  


Count the length of each run of 1s (space) or 0s (hash) in the image, ignoring new lines - yields a list: [4,2,11,1,1,...];  
Subtract one from each number - this gives a range of [0,15];  
Treat this as a base-16 number (enumerate the values, v, with index i in reverse and sum up 16**i*v = 19468823747267181273462257760938030726282593096816512166437);  
Convert this to base-250: [5,119,249,42,...];  
Map into Jelly's code page as indexes: ¥vẏ)X;ndĊɓ¡ẹ3ċi}Ịɲ¡P


Now the code evaluates this number, maps the 1s and 0s to space and hash characters*, doubles each, splits into lines and repeats each the appropriate number of times.
* actually the implementation is performed modulo 2 to save bytes, so spaces are odd and hashes are even:

“¥vẏ)X;ndĊɓ¡ẹ3ċi}Ịɲ¡P"¦ḊƥṾ’                  - base 250 number, as above
                           b⁴                - convert to base 16 (the run length - 1 list)
                             ‘               - increment (vectorises) (the run length list)
                              Ė              - enumerate (pairs each with 1,2,3...)
                               Œṙ            - run length decode
                                              ([1,1,1,1,2,2,3,3,3,3,3,3,3,3,3,3,3,4,5,...])
                                  ⁾ #        - string " #"
                                 ị           - index into (1 based and modular)
                                              (makes a bomb without line feeds)
                                     Ḥ       - double (each char becomes a list of 2 chars)
                                      s⁴     - split into slices of length 16
                                        ẋ€³  - repeat each input, n, times
                                           Y - join with line feeds
