Methods of Optimizing Boiler Efficiency and Reducing NOx Emission
The article explores NOx pollution from fossil fuel combustion, advocating Flue Gas Recirculation (FGR) for up to 50% reduction. It highlights sources, FGR benefits, and
Boiler burners are divided into two types.
a burner head unit and a ventilator system unit. The burner head unit consists of a burner body, gas nozzles, a swirler, a diffuser, a light oil train, an electrical panel, safety devices, and wiring. The ventilator system includes a fan, electromotor, and electrical panel. The ventilator system can install in the same room or a different area, and an Air-Duct connects the two units. As follows, we will illustrate that Dual block burners have more benefits than Monoblock burners in large industrial burners.
Also, one of the dual block burner abilities is to install the fan in a separate area from the boiler room, which has many benefits:

During the last century, Nitrogen oxide emissions, called NOx, have constantly been increasing. Due to the destructive effects of nitrogen oxides on the health of
The «furnace industry» and products determine the type of flame contact. In many heat treatment processes, where the combustion gases must not come into contact
Full electronic modulating burners are designed to safely operate throughout its firing range from high fire to low fire. The most common turndown ratings in DB-Series (dual block) burner are 1:8 up to 1:10. High turndown is used to reduce the burner cycling and maintain a consistent temperature or pressure in the boiler. This is crucial if the boiler is used in an industrial process that requires a consistent temperature or pressure. dual block burners are equipped with an electronic microprocessor management panel, which controls the air damper servomotor, fuel servomotors as well as head regulating sleeve. Using electronic modulation, hysteresis is prevented by the precise control of the separated independent servomotors and the software linked by can-bus. The LAMTEC ETAMATIC / CMS combustion managers or Siemens LMV51/52, as the most popular brands, are frequently used in DB-Series RAADMAN Modular burners. This burner Control System combines the benefits of an electronic fuel/air ratio controller with an electronic burner control unit. Up to five motorized actuators can be assigned to modulate air and fuel drives with the option of an additional module to add variable speed drive control for the combustion air fan. Additional modules are available for field bus interfacing, load control and dual fuel operation.
These modular systems include many standard burner functions as standard, these include integrated valve proving, ambient temperature compensation, flame monitoring and operating hours and system start-up counters. Oxygen trim, CO control, load control and dual fuel functionality are all available options that are used to further enhance system benefits, flexibility and efficiency. These controllers are particularly suited for use on monobloc burners.
Key features and benefits include
For all purposes and possibilities
They can be used wherever heat is needed – in heating residences or hospitals, schools or offices, in industry or trade, on board ships and for mobile plants. They are suitable for all commonly available gas and oil types and are notable for their reliability, longevity and great economy. Nearly all burner types over the entire performance range are available in a Low NOx version, with particularly low emission levels.
BD-series, as a dual-bloc concept, covers a range of 1000-32000 kW in 9 versions/capacities with 1:8 to 1:10 turndown ratio.
PACKMAN Company was established in February, 1975. The company has started its activity in the field of producing High-Pressure Vessels such as Hot-Water Boilers, Steam Boilers, Pool Coil Tanks, Softeners and Heat Exchangers since 1984.
