LOW NOx BURNER
LOW NOx BURNER FEATURES
■ Low NOx emission (60ppm, combustion air temp @ ambient)
■ No moving parts for reliable service.
■ Low draft loss enabling low power loss of F/D fan
■ Able to run with low excess air (O₂2%)
■ BP-108 code applied
■ Suitable for vertical, horizontal or angles application
■ Burner design developed using the test facilities
■ Many reference lists for industrial & power boilers and hot oil heater

BURNER DESIGN
For many years Hamworthy have been in the forefront of burner design and recognised as a burner supplier of equipment capable of high combustion efficiency. Burners in operation have met stringent limits on particulate emissions, coupled with low excess air operation for maximum efficiency and acid corrosion control. As its Pool works it has large combustion test facilities, enabling development programmes and trials to be effected with full scale burners. The test rigs are also available for customer demonstration. Fully instrumented for the measurement of NOx, oxygen, particulates and carbon monoxide, it provides one of the most comprehensive research and development installation throughout the Combustion Industry. More recent demands to reduce the level of nitrogen oxides being emitted, without increasing particulates emissions or compromising efficiency, have not gone unheeded. These have enabled Hamworthy to meet levels demanded not only by the U.K. 'Environmental Protection Act', but also more demanding and tougher standards set it other European countries and North America.
