An apparatus for generating a black smoke signal is provided. The apparatus includes an acetylene burner assembly that further includes an acetylene delivery structure, a perforated burner head disposed at an end of the acetylene delivery structure, and an electric spark igniter disposed adjacent to the perforated burner head, so as to allow a flow of acetylene through the perforated burner head to be ignited. An acetylene flow control system provides acetylene at a rate that causes the acetylene to be partially combusted in atmospheric oxygen through the acetylene burner assembly, so as to generate black smoke.
