Scientific fundamentals and research

Scientific article titled “The New Physical Interpretation of a Flame Front Thickness”, presented by Periflame’s Director of Engineering Iurii Kryzhanovskyi and is published in the “Journal of Energy and Power Sources”, Vol. 1, No. 1, 2014 in July 31, 2014

The new interpretation of the concept of the thickness of a normal flame front and interconnection between the flame front propagation rate, and the specific volume intensity of combustion was presented. Independence of specific volume intensity of combustion upon flow regime has been shown. The new interpretation of the Peclet number for flame was tested. Test results allow drawing a conclusion about existence of an ordered internal structure of a flame front and about new regularities. Researches of the laminar flame front structure for the purpose of its detailing have been made. The measurement of СО2 and NO concentrations and temperatures within a laminar flame front of methane-air mixture at various initial temperatures and excess-air factors has been fulfilled. There was revealed a necessary condition for existence of a self-spreading wave of reaction defined by view of a concentration profile. It was revealed hydrogen burns out as if it was in the free molecular state at burning of hydrocarbons. Explanation of these results demands improvement of a nowadays understanding of combustion process.

Novel Combustion Technology Overview

Microdiffusion Combustion Technology (MCT) Overview:

  • Microdiffusion combustion process enables achievement of the highest scientific echelon of burning
  • MCT provides flame-holders with a structural stabilization zone instead of disorderly mixing and turbulization
  • Advanced topological schemas eliminate the need for swirling vanes and other types of  turbulizers

What performance can you achieve together with MCT:

Increasing efficiency & fuel saving due to

  • Transparent flame over the entire capacity range with maximal convective heat transfer
  • Ecology-friendly, significant NOx and thermal pollution reduction
  • Low NOx emissions due to the utilization of proprietary fuel allocation and adjustable flame aeration methods

Ecology friendly providing lowest NOx and thermal pollutions

  • Low NOx emissions due to the complex of the unique microdiffusion method of the fuel allocation along with the adjustable flame aeration
  • Low level of thermal pollution over the entire capacity range due to a minimum possible air/fuel ratios

Safety, reliability & operational advantages

  • Minimum possible inlet gas (oil) pressure and any required air pressure difference
  • Optimal performance over the capacity range from 10 to 100%

Each burner undergoes rigorous testing and safety inspection

PeriFlame’s Heavy-Oil Burners product line

To address increasing market demands for Waste Oil Burners (WOB), PeriFlame offers patented Heavy-Oil Burners product line (MD-OW) tuned for unconventional fuel types.

PeriFlame understands challenges that come with Waste Oil Combustion.  Our patented MD-OHW product line alleviates our Customers of conventional challenges and addresses our Customer’s combustion needs.  (For additional info, see:  Advantages of MD-OW Burners)

In 2013, Periflame put into operation dozens of WOB in highly-developing European markets, to include,   Steam Boilers plants, Grain drying facilities, etc.

Brief overview of successful adaptation:

·         PeriFlame’s patented straight flow topological schema provides optimal concentration and temperature pattern of combustion zone, yielding complete combustion.

·         PeriFlame’s patented design of pneumatic atomizers allow burner’s adjustments to customer defined fuel types and burner application.
Advantages of MD-OHW Burners patented design:

·         Exclude all potential issues found with high pressure configurations.

o   Atomization quality doesn’t depend on fuel pressure and is determined only by atomizing air pressure.

·         Prevent nozzle clogging and carbon deposits on the burner’s frontal case.

·         Decrease fuel pressure to 2-4 bars (especially important for high-viscosity fuels).

·         Straight-flow burner schema allows using outlet burner nozzles of various cross-section configurations.
