RSP BURNER

The 'RSP' series of gas burners are pre-packaged fan assisted units designed to suit virtually all types of low temperature gas fired application; typical applications include the firing of industrial ovens and driers.

The RSP can be fitted into process air ducts having air velocities of 5 to 25m/sec. (recommended = 7.5m/sec) - Air flow should be uniform across the air duct, both upstream and downstream of the burner.

The burners can be installed in a process plant recirculation system were 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 sideplate so as to fire parallel to the sideplate in the direction of air flow.

All the air required for combustion is supplied by a combustion air fan mounted on the outside of the sideplate - air is passed to the burner head via an integral air duct.

Process air temperatures up to 400C can be accepted upstream of the burner - downstream temperatures should be limited to 700C.

A heat resistant viewing window and small access plate is fitted into the sideplate and allows visual inspection of the flame during operation.

The nozzle mix design of the burner and the progressive air mixing feature of the combustion head ensure that burners can operate with high turn down capability; turndown ratios up to 40:1 are possible depending on burner applications and selection.

PREPACKAGED ASSEMBLIES

Each burner unit is supplied with a packaged and prepiped valve assembly, including the safety valves and controls necessary to form a fully pre-packaged combustion module.

All burners have an integral combustion air pressure switch, ignition spark plug and flame sensor; all the electrical components on the burner are prewired to a terminal enclosure mounted on the burner assembly.

The electrical terminal enclosure would normally be fitted with burner run and flame failure indication lights.

Burners are normally supplied complete with a gas valve assembly consisting of pilot/start valve assembly, safety shut off valves, pressure switches and governors; the exact type of valve assembly will depend on the application and the country of installation.

Burners are normally fitted with complete prewired automatic ignition and flame safety equipment.

Most types of flame failure and automatic ignition control units can be supplied; utilising either flame rectification or ultra-violet flame sensing equipment.

Burners can be supplied with extra large control consoles containing special control gear and switchgear to suit the requirements of any specific application; burners can be supplied with special valve arrangements; burners are supplied with left handed (SF) valve assemblies unless otherwise specified.

Fully prebuilt burner packages are fully tested and the operation of all components checked before despatch from the factory.

SPECIAL APPLICATIONS

The standard range of RSP burners are designed to be installed on the suction (negative) side of the oven/dryer process air fan.

Burners can be supplied fitted with higher pressure combustion air fans so that burners can be installed on the pressure side of the process air fan.

Burners supplied for installation into positive chamber/duct pressures are fitted with a three way solenoid valve system designed to ensure correct supervision of the combustion air fan pressure switch.

BURNERS FOR HIGH TEMPERATURES

Standard RSP burners are supplied with uninsulated sideplates; when burners are required for high oven temperatures the sideplate can be insulated.

Insulation is of a high quality type with excellent insulation properties; insulation thicknesses of either 100mm or 150mm can be supplied.

To prevent ingress of insulation material in to the process air stream the insulation is completely cladded and welded to the sideplate with stainless steel.

TYPES OF CONTROL AVAILABLE

RSP burners can be supplied suitable for high-low control operation; however the majority of burners are supplied as fully modulation controlled units.

Burners are normally fitted with electrical motorised butterfly valves although other types of control valve can be fitted when required (e.g. pneumatic)

The control valves can be fitted with all types of control motor to accept all types of input control signal.
