The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.
The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.
· the principle of a low NOx burner technology is At the same time the flame structure also works to reduce the oxygen supply to the hottest part of the flame This not only improves the efficiency of the burner but also decreases the risk of production of NOx The process is successfully attained in three different stages:
Product Description (gas: pyrolysis coal blast furnace coal gascoke oven coal and producer coal) The fundamental reason for the generation of NOx in gas is that the combustion temperature of the gas burner is too high and the flue stays for too long in the furnace the air excess factor is too large
· An Introduction Among the variety of industrial burners the or is basically utilized in the utility boilers to regenerate steam and electricity These are said to be uniquely regenerative which modifies fuel before combustion process which then forms and burns soot within flame
LOW NOX BOILERS AND BURNERS Available for ALL Boilers Our boilers can burn any liquid or gaseous fuel; and come in sizes from 100 to 2500 horsepower with pressures to 450 PSI Hurst boilers are designed and engineered with larger furnaces providing for inherently lower NOx emissions To produce lower emissions our boilers employ technologies such as; gas and air pre-mix flue gas
With a 100-million-Btuh-fuel-input gas boiler the average emission factor for an uncontrolled burner is roughly 85 ppm; for a low-NOx burner it is and for a low-NOx burner with FGR it is 26 ppm1 Keep in mind these are average emissions; they are not regulation requirements and are not to be used as a basis for an air-permit application
ZEECO® Burners Zeeco offers a comprehensive portfolio of package burners conventional burners duct burners and low-NOx and ultra-low NOx process and power/steam boiler burners that are world renowned for energy efficiency and performance From modular units for commercial applications to fully engineered systems for complex burner configurations Zeeco employs its own
Patented Proven Performance Burner Dynamics Inc (BDI) designs and manufactures natural gas burners for industrial boilers and furnaces BDIs patented burner design delivers industry-leading NOx reductions coupled with significant fuel savings and lower combustion noise The unique vortex mixing technology utilized in BDI burner designs produces NOx reductions
The FIR can achieve ULN emissions of less than 10 ppm without the use of flue recirculation The unique burner design provides excellent flame retention for stable combustion at sub-9 ppm NOx levels These levels of NOx and CO will meet the stringent emission requirements found in California Houston and other non-attainment zones Two using FIR burners are installed and running at
