KBR's proven Top-fired Steam Methane Reformer (SMR) as implemented at a recent grass roots ammonia plant.
For conventional methane reforming operations, KBR's top-fired steam-methane reformers (SMR) design circumvents many of the mechanical design problems in competitor's primary reformer designs. The reformer tubes are efficiently heated from both sides, with firing occurring downwards from the top of the firebox, providing a relatively even load along the tubes. The convection section provides heat recovery from the flue gas for optimum furnace efficiency. Additionally, KBR's fired reformer can also be coupled with a gas turbine that drives an air compressor. This design allows the gas turbine exhaust to be used as preheated combustion air for the reformer radiant section, which reduces overall plant energy consumption.
