Title:
COMPACT DUAL-FUEL COMBUSTION SYSTEM, AND FLUID HEATING SYSTEM AND PACKAGED BURNER SYSTEM INCLUDING THE SAME
Document Type and Number:
WIPO Patent Application WO/2019/207559
Kind Code:
A3
Abstract:
An inward-firing dual fuel combustion burner system comprising a burner casing configured to receive a gaseous mixture at a burner inlet and to provide hot combustion gas at a burner output; a combustion substrate disposed within the burner casing, the substrate having a shape comprising at least a semi-cone, having a substrate angle measured from a longitudinal axis, having a substrate porosity defined by a plurality of pores, and having a substrate inner surface and a substrate outer surface; the substrate configured to receive the fuel-air mixture at the outer surface of the substrate, the fuel-air mixture passing through the pores at a mixture flow rate from the substrate outer surface toward the substrate inner surface; one or a plurality of oil nozzles disposed within the combustion cavity defined by the substrate in fluidic communication with a source of pre-heated and pre-pressurized oil fuel, an oil nozzle configured to receive the oil fuel and disperse the oil fuel into the cavity; the burner configured to be operated using either a gaseous premix fuel air mixture or a pre-heated and pre-pressurized liquid fuel oil; the burner configured such that, during gaseous premix fuel operation, the fuel-air mixture ignites near the plurality of pores to form a respective plurality of flamelets, each flamelet corresponding to one of the pores; and the burner configured such that, during oil fuel operation, the oil mixture ignites during isenthalpic expansion.
