Comtherm RSP Burner

Comtherm RSP Burner

The RSP series of gas burners are pre-packaged, fan assisted units designed to suit virtually all types of gas fired applications where recirculated air is utilised; typical applications include the firing of industrial ovens and dryers. The RSP can be fitted into process air ducts having air velocities of 5 to 30m/sec. The burners can be installed in a process plant recirculation system where it is not possible to construct a combustion chamber and install a conventional type of burner assembly. The RSP burners consist of an ‘in-line` PH type combustion head mounted on a side plate so as to fire parallel to the side plate in the direction of air flow.

The units are available in two output capacities; the standard RSP is 300 kW per 300mm and the RSP-HC is 600 kW per 300mm. The heads are available in ‘straight`, ‘T` and ‘X` sections which enable the burner to be constructed to suit the appliance layout. All the air required for combustion is supplied by a combustion air fan mounted on the outside of the side plate – air is passed to the burner head via an integral air duct. Process air temperatures up to 300°C can be accepted upstream of the burner. Downstream temperatures should be limited to 450°C. The burner system produces a wide flame spread and short flame; this feature makes the burner ideal for applications where chamber length is restricted.

The RSP burner is simple and safe to operate. All burners are pre-fired and fully tested before leaving our works.
