class Ifc4x2::IfcBurner : public Ifc4x2::IfcEnergyConversionDevice

A burner is a device that converts fuel into heat through combustion. It includes gas, oil, and wood burners.

HISTORY New entity in IFC2x4

Type Use Definition IfcBurner defines the occurrence of any burner; common information about burner types is handled by IfcBurnerType. The IfcBurnerType (if present) may establish the common type name, usage (predefined type), properties, materials, ports, composition, assignments, and representations. The IfcBurnerType is attached using the IfcRelDefinesByType objectified relationship and is accessible by the IsTypedBy inverse attribute. If the IfcBurnerType has ports or aggregated elements, such objects are reflected at the IfcBurner occurrence using the IfcRelDefinesByObject relationship.

Property Use Definition The property sets relating to this entity are defined by IfcPropertySet and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. Property sets may also be specified at the IfcBurnerType, defining the common property data for all occurrences of the same type. They are then accessible by the IsTypedBy inverse attribute pointing to IfcBurnerType.HasPropertySets. If both are given, then the properties directly defined at IfcBurner override the properties defined at IfcBurnerType. Refer to the documentation at the supertype IfcEnergyConversionDevice and ancestors for inherited property set definitions. The following property set definitions are applicable to this entity: Pset_BurnerTypeCommon (PSET_TYPEDRIVENOVERRIDE)

Quantity Use Definition The quantities relating to this entity are defined by IfcElementQuantity and attached by the IfcRelDefinesByProperties relationship. They are accessible by the IsDefinedBy inverse attribute. The following base quantities are defined and shall be exchanged with the IfcElementQuantity.Name = ‘BaseQuantities’. Other quantities, being subjected to local standard of measurement, may be defined with another string value assigned to Name. In this case a valid value for MethodOfMeasurement shall be provided.


Material Use Definition The material of the IfcBurner is defined by IfcMaterialConstituentSet or as a fallback by IfcMaterial, and attached by the RelatingMaterial attribute on the IfcRelAssociatesMaterial relationship. It is accessible by the HasAssociations inverse attribute. Material information can also be given at the IfcBurnerType, defining the common attribute data for all occurrences of the same type. The following keywords for IfcMaterialConstituentSet.MaterialConstituents[n].Name shall be used:

Body: The primary material from which the object is constructed. Fuel: Material designed to be burned.

Port Use Definition The distribution ports relating to the IfcBurner are defined by IfcDistributionPort and attached by the IfcRelConnectsPortToElement relationship. If the burner occurrence is defined by IfcBurnerType, then the port occurrences must reflect those defined at the IfcBurnerType using the IfcRelDefinesByObject relationship. Ports are specific to the IfcBurner PredefinedType as follows indicated by the IfcDistributionPort Name, PredefinedType, and FlowDirection:

Gas (GAS, SINK): Gas inlet for burner.
