The study of air fuel ratio for open furnace MILD combustion of biogas on bluff-body burner [PDF]

, 2012
Economical fuel cost is very critical in the heating industry. Lean combustion with high air fuel ratio (AFR) is normally practiced by the industry. Low air fuel ratio or rich combustion will result in unburned hydrocarbons (UHC).

Numerical Modeling of Direct Current Plasma Versus Natural Gas‐Heated Steelmaking Ladles: Validation via Full‐Scale Industrial Measurements

steel research international, Volume 96, Issue 8, August 2025.
This study explores using DC plasma torches with nitrogen as a carrier gas for preheating large steelmaking ladles. Numerical models simulate ladles preheated by 0.7 and 1.5 MW plasma torches, compared to natural gas heating. Results show plasma torches achieve significantly higher bottom temperatures, validated by industrial measurements on full‐sized

Research and Application of High‐Sensitivity Grounding Fault Startup Method for Forest and Grassland Distribution Networks Based on Zero‐Sequence Voltage Vector

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
This paper constructs a phase‐to‐earth fault startup method based on the vector form of zero‐sequence voltage, which can enhance the high‐resistance detection capability up to 100 kΩ under different grounded system. ABSTRACT Single‐phase ground faults in forest and grassland distribution networks pose a risk of igniting wildfires, necessitating ...
