摘要： A combustion burner using hydrogen as the primary fuel and including a burner housing, a hydrogen fuel conduit extending within the housing and defining a hydrogen fuel exit opening, a combustion air conduit extending within the housing and defining a combustion air exit opening, a hydrocarbon fuel conduit defining a hydrocarbon fuel exit opening, and a mixing/combustion zone in which the hydrogen fuel, the combustion air, and the hydrocarbon fuel mix and combustion takes place. The hydrocarbon fuel exit opening is positioned such that the hydrocarbon fuel is heated prior to mixing with the combustion air injected from the combustion air opening. Also, a method of firing a combustion burner using hydrogen as the primary fuel, where hydrogen fuel, combustion air, and hydrocarbon fuel are injected into a mixing/combustion zone of the combustion burner such that the hydrocarbon fuel is heated prior to mixing with the combustion air.

摘要： A method for providing uniform temperature in a furnace, such as a soaking pit or a reheat furnace is disclosed. Temperatures at a front wall and a burner wall within the heating chamber are constantly monitored by a computer, and the computer operates a direct-fired burner, or for example, a pair of regenerative burners, in one of two modes to place heat either at the front wall or the burner wall. The burner is oversized in relation to a maximum firing rate required by the heating chamber design. To heat the front wall, an impulse firing mode is initiated by the computer wherein the burner is fired at its full, overrated capacity for a time proportionally less than a normal firing cycle. To heat the burner wall, the computer initiates a proportional firing mode wherein the burner is fired for the full normal cycle, but at a rate which is equivalent to the actual firing rate demand calculated by the computer. These firing modes may be combined throughout an entire heating campaign to uniformly heat the heating chamber.

摘要： The radiant tube burner assembly comprises a radiant tube having a burner leg and an exhaust leg. A plenum for mixing combustion air and products of combustion from the exhaust leg is positioned to direct the resultant mixture into the burner leg. A jet pump for directing high velocity combustion air through a nozzle and along a central longitudinal axis of the plenum aspirates the products of combustion from the exhaust leg through a duct in registry with the plenum and the exhaust leg. A restricted orifice associated with the duct is dimensioned and sized in relation to the jet pump nozzle to control the amount of products of combustion aspirated to the plenum. A conventional fuel source including a fuel pipe and conventional exhaust means also form a part of the assembly.
