Abstract: A duct burner assembly for a HRSG having a casing that defines a combustion chamber with a liner for communicating an exhaust gas. A firing runner attaches to the liner and extends through the combustion chamber. The firing runner defines a plurality of orifices for emitting combustible gas and sustaining a flame. A flame stabilizer attaches to the firing runner and is configured to at least partially shield the plurality of orifices from the exhaust gas. A guide plate attaches to the firing runner and is configured to define a slot between the liner and the guide plate. The guide plate has an upstream end and a downstream end wherein the downstream end is closer to the lining than the upstream end to control turbulent flow of the exhaust gas through the slot and cool the liner. To reduce generation of flow turbulence the tubes within the slot are covered with streamline plates. It allows to decrease a mixing between hot and cold gas flows and improve the liner cooling.

Abstract: A technique of controlling a steam generating boiler system having multiple superheater sections includes determining multiple control signals to control a temperature of output steam to a turbine. The technique uses a first control block to determine an offset value based on multiple input temperatures and a dynamic matrix control (DMC) block to determine input steam control signals based on an output temperature and an output temperature setpoint. The technique modifies one of the input steam control signals based on the offset value. The modified input steam control signal and the unmodified input steam control signal are provided to respective field devices to control the input temperatures and, as a result, the output temperature.

Abstract: A door with a gas burner on an inner surface and a system for carrying a combustible gas to the burner on the outer surface thereof. The door comprises a pair of metal sheets rigidly connected to one another at the edges thereof, each sheet having input and output openings for the gas mixture that are mutually separated in order to leave an inner space receiving a deflector plate serving as a thermal shield to be swept over on either side by the flow of the gas mixture supplying the burner. This arrangement reduces heat loss through the door; thus, keeping the outer surface cold, avoiding the risk of burns, and preheating the gas mixture. The invention can be used in heating appliances.

After the post-exposure bake process, the substrate is transferred from the heating unit to the reserved cooling unit which is reserved in advance and subjected to a cooling treatment therein.

Abstract: A fuel-fired furnace incorporates specially designed fuel/air mixing and combustion structures. The fuel/air mixing structure is of a mixing sound-attenuating design and comprises a venturi having a perforated sidewall portion and being surrounded by a noise-damping housing chamber communicating with the interior of the venturi via its sidewall perforations. During use of the mixing structure, air is flowed through the venturi in a swirling pattern while fuel is transversely injected internally against the swirling air. The combustion structure comprises a burner box housing into which the fuel/air mixture is flowed, combusted, and then discharged as hot combustion gas into and through the heat exchanger tubes. The fuel/air mixture entering the burner box housing initially passes through a non-uniformly perforated diffuser plate functioning to substantially alter in a predetermined manner the relative combustion gas flow rates through the heat exchanger tubes.
