Main Gas burners & pilots in operation |
The original 9 x 9MW natural gas burners have been adapted to accept the Credfeld Hazardous Area Igniters, that double as permanent pilots to enable the main burners to be turned off when not required and the boiler to be returned to service seamlessly without having to go through a boiler purge cycle. This has been done to increase availability considerably without compromising on safety, efficiency, reliability or other operational parameters.

35% NOx Reduction on Heavy Oil Firing with Credfeld Osynox Atomizers & Swirlers
Credfeld have installed two boiler sets 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 Units 1 and 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.
The Graphical Emission Report below shows Unit 1 and 2's performance over the period, 11th July to 10th August 2010 and the dramatic decrease in NOx emissions from Unit 1 when the new Osynox atomizers were sequentially fitted and the combustion trimmed between 1st August 2010 and 3rd August 2010. During this period the NOx was reduced from 800mg/Nm3 NOx to 450mg/Nm3 NOx. The new Swirlers are yet to fitted on Unit 1 to bring it inline with Unit 2.

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.

Credfeld have completed commissioning the 3rd Boiler at Rio Tinto Alcan, Lynemouth Power Station. This included Air Atomised PF Light Up Burners, Oil Flame Eyes, Coal Flame Eyes, LT300 Igniters & Burner Management Systems. In addition to this a fibre optic communications link was installed to the Power Station Control Centre to show the coal flame signal strength on each burner. The Coal & Oil Flame Scanners have been configured to give 100% discrimination under all load conditions. |
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.
