Abstract: A gas burner system comprising a longitudinal burner body defining a longitudinal central cavity, and a ribbon pack configured to be removably installed into the central cavity, the ribbon pack comprising: (i) at least one ribbon positioned between a first vertical wall and a second vertical wall; (ii) a first transverse arm extending horizontally outward from a first longitudinal side of the ribbon pack; (iii) a second transverse arm extending horizontally outward from a second longitudinal side of the ribbon pack, wherein the first and second transverse arms are configured to attach to the longitudinal burner body.

Abstract: An apparatus and method for extracting and recovering water-soluble gas and waste heat from an oven is provided. The method employs a gas-gas heat exchanger for cooling hot stack gas from the oven to a temperature higher than the dew point of the hot stack gas, a double-film-wise heat exchanger for receiving the cooled stack gas from the gas-gas heat exchanger, a condenser/heat exchanger for receiving and further cooling the stack gas from the double-film-wise heat exchanger to ambient temperature by heating a utility water stream, which can then be used for hot water and steam process services, and an ethanol recovery unit for receiving the cooled stack gas from the condenser/heat exchanger.
