Energy Efficiency Comparison ·

Regenerative Burner: Achieves thermal efficiency exceeding 85%, with flue gas temperature reduced to below 200°℃. Its core principle involves heat recovery from high-temperature flue gases through regenerators, preheating combustion air to near furnace temperature (100-150°℃ lower than furnace temperature), thereby significantly reducing fuel consumption. Conventional Burner (e.g., conventional centralized heat exchanger type): Thermal efficiency approximately 60%.

Energy saving range

Compared with traditional burners, the theoretical energy saving rate of regenerative burners can reach more than 20%. This conclusion is based on the significant reduction of exhaust temperature (optimized from high temperature exhaust of traditional burners to below 200) and the improvement of air preheating efficiency.

Key Energy-saving Mechanism

Technical Features:

High-efficiency heat storage recovery:

The thermal storage medium alternately absorbs flue gas heat and preheats air to minimize heat loss.

High-temperature combustion:

Preheated hot air enhances combustion efficiency while reducing fuel consumption. Structural optimization:

Design elements like built-in secondary gas pipes and air swirl plates ensure thorough gas-air mixing, minimizing incomplete combustion losses.

Summary

The regenerative burner achieves more than 20% energy saving effect compared with the traditional burner through regenerative heat recovery and high temperature air combustion technology, and the thermal efficiency is increased to more than 85%, which is an important energy-saving technological innovation in the field of industrial heating.
