摘要： The present disclosure relates to a flue gas exhaust system for an industrial furnace, especially a steam reforming furnace. The flue gas exhaust system comprises a stack having an inlet opening for introducing flue gas into the stack and an outlet opening for exhausting flue gas. The inlet opening of the stack is in fluid connection to an outlet of a heat recovery system of the industrial furnace. Further, the fluid connection between said heat recovery system outlet and said stack inlet opening comprises a transition flue gas duct that at least partly embraces a part of the stack.

摘要： A waste heat boiler system for cooling a process gas, including a first shell-and-tube heat exchanger for cooling relatively hot gas down to relatively warm gas, an intermediate chamber for receiving gas, cooled down to relatively warm gas, coming out of tubes of the first heat exchanger, and a second shell-and-tube heat exchanger for cooling relatively warm gas further down to relatively cool gas. The intermediate chamber is provided with an outlet fluidly connected to a bypass channel for allowing a part of the relatively warm gas to bypass tubes of the second heat exchanger. The bypass channel and tubes of the second heat exchanger are both fluidly connected with a mixing chamber for mixing together relatively warm gas flowed from the intermediate chamber into the mixing chamber via the bypass channel and relatively cool gas come out of the tubes of the second heat exchanger.
