35% NOx Reduction on Heavy Oil Firing with Credfeld Osynox Atomizers & Swirlers

Credfeld have installed an initial boiler set of Low NOx heavy oil Osynox atomizers and matched swirl vane flame stabilizers at Delimara Power Station in Malta.  These have been fitted to bring the emissions down in line with the latest regulations of 450mg/Nm3 NOx and a corresponding particulate emission limit of 50mg/Nm3 for existing plant.

New Credfeld Osynox atomizers & swirlers

The original 6 x 41MW heavy oil burners on Unit 2 have been adapted to accept the Credfeld critical components that have been proven on many installations elsewhere to reduce emissions considerably without compromising on efficiency or other operational parameters. 

One UK Power Station was supplied with 6 prototype Hydrapower Valve Assemblies to replace the old Shuttle units that were experiencing excessive wear due to new types of fuels being fired.  The new assemblies have been designed as a direct replacement for the old units & are compatible with the existing oil guns & fuel supply & return system. Once field trials were proven satisfactory the site has now ordered 50 units & will eventually have 108 when all the burners have been re-fitted.

 Credfeld have recently designed, manufactured and supplied two Low NOx Dual Gun Oil Burners for one 60 T/H water tube boiler to be supplied to a site in the Middle East.

The scope of our supply included two Dual Gun Heavy Oil Burners mounted in individual Windboxes complete with individual Air Control Dampers; one Twin Burner Management and Combustion Control Panel; one forced draught fan suitable for two Burners' air supply; one Main Fuel Supply Skid with Atomizing Steam Station and individual Burner Valve Trains.

The scope also included Credfeld LT300 Igniters and Flame Eye FE2020 main flame scanners all interconnected to a Local Panel mounted on each Windbox.

Credfeld have recently supplied and installed Flame Eye FE4 UV/IR Multi-Fuel Flame Scanners to a Heat and Power Plant in Scandinavia.  The installation and commissioning was carried out in less than one week to the delight of the customer  and further sets were ordered and delivered for other boilers on the site.

In February 2008, Credfeld Ltd signed an exclusive agreement with Kdwin Tech for representation in Korea for combustion systems.  Credfeld completed many installations in the past and the new agent will be looking to build on the existing good reputation for quality products and low emission combustion.  There is also a good potential for spare  parts procurement through Kdwin Tech.

Credfeld have commissioned and tested a Single Burner Package, complete with Oil Flame Eye suitable for firing Diesel Fuel with Zero Soot emissions at 0.5% O2. The burner was tested at 0.4 MW and also at 1.04 MW in the same combustion chamber and utilised our standard Low NOx Burner Design scaled down to suit the application.

In December 2006 Credfeld was assigned to supply and install 32 LT 300XL Ignition Systems for a UK Oil Fired Power Station.

Credfeld have successfully secured the contract to supply the second phase of 12 Oil Guns and Coupling Blocks complete with Low NOx Atomisers for a Power Station in the North East of England.

In August 2006 Credfeld was assigned to supply and install 138 Credfeld Flame Eye and LT300 Ignition systems to Grootvlei Power Station in South Africa.
