As standard, burners have the following features:
- Flame viewing port located at the rear of the burner, enabling a unique view of the combustion process.
- Fuel input fixings on either side of the burner, allowing flexibility for site conditions.
- Fitted terminal box from which a 32 way socket connects the burner to a control unit, allowing it to be disconnected and isolated when required.
- Stainless steel diffusers and blast tubes.
- Damper to control air input mounted using sealed bearings for improved control and reliability.
Oil control on the burner is hydraulically operated to ensure absolutely no after burn, this is achieved using a piston controlled shut-off valve closing directly on the oil nozzle outlet. The hydraulic circuit is operated on a 25 bar supply pressure. Nozzles are made of high-alloyed steel to ensure the best possible burn out behavior for variable oil quality. The amount of oil supplied to the nozzle is controlled by a spillback type oil valve on the nozzles return line.
Gaseous fuel is injected at high velocity into the air stream prior to the stainless steel mixing diffuser. The natural gas input volume is controlled via a precision made flange butterfly valve enabling one positioning motor to be used for both fuels. A completely linkageless procedure. Limpsfield Combustion also manufacture Gas Control Trains. These are supplied complete with pilot control train, double block control valves, regulators and isolation valves. Optional equipment includes: gas filters, pressure proving equipment, high pressure shut-off valves, gauges and switches.
Low NOx Capabilities / Flue Gas Re-circulation
All burners are capable of meeting tough US federal codes regarding low NOx emissions. Numerous installations of this nature have been made with excellent results.
Sub-30ppm NO emissions at 3% O2 can be attained. This is due to the utilisation of flue gas re-circulation and the superior flame retention and mixing achievable from the Limpsfield design.
Limpsfield offers its users control panels to accompany the burners. These are designed and built around advanced combustion control equipment which will optimize reliability and performance of the LC burner. All panels are UL approved and built in an ISO9001 environment. In addition, panel design and specification can be tailored to the end user's specific requirements.
