A well test burner system has a plurality of burner nozzles supported by a support structure. Each burner nozzle has an air inlet, a well product inlet and an air/well product mixture outlet. At least one of the burner nozzles is supported to pivot relative to the support structure while the burner nozzle is operating to expel air/well product mixture.

A combustor arrangement includes a combustion chamber with a front panel, and a premix burner of the multi-cone type, which is connected to the front panel through an elongated mixing zone in an axially moveable fashion by a sealed sliding joint. A wide range of axial variation of the burner with a minimized influence of the leakage air flow on the oxidation process within the flame is achieved by positioning the sealed sliding joint upstream of the mixing zone.

A combustion system includes a fuel and oxidant source, a perforated flame holder, and a support structure that supports the perforated flame holder at a selected distance from the fuel and oxidant source. The fuel and oxidant source outputs fuel and oxidant onto the perforated flame holder. The perforated flame holder receives the fuel and oxidant and sustains a combustion reaction of the fuel and oxidant within the perforated flame holder.

The present disclosure describes an assembly configured to mitigate the harmful effects of smelt fouling, airflow interference, and operator exposure to hot air from the furnace and wind box through use of an extractable startup burner and an isolation chamber engaged to a windbox. The present disclosure also describes a method for safely extracting a startup burner from an active recovery boiler as has method for inserting an extractable startup burner into a recovery boiler during operation.
