Breakthrough in low calorific value gas combustion technology brings new solutions for emission reduction in industrial furnaces and kilns

2025-04-08

  Significant breakthroughs have recently been achieved in the field of low-calorific gas combustion technology, bringing new solutions to emission reduction efforts in industrial furnaces and kilns.

  Traditionally, low-calorific gas, due to its low calorific value, has been difficult to utilize efficiently and is often disposed of through direct discharge. This not only results in resource waste but also exacerbates air pollution. However, with continuous technological advancements, the combustion efficiency of low-calorific gas has been significantly improved.

  The "High-efficiency and Clean Intelligent Recovery and Utilization Technology and Equipment for Metallurgical Low-calorific Waste Gas" successfully developed by China Metallurgical Group Southern Engineering & Technology Co., Ltd. is a prime example. This technology, through automated control technology, achieves automatic adjustment of waste gas volume, air supply volume, and induced draft volume, maintaining combustion conditions. This significantly increases the pressure and temperature of the main steam generated by gas combustion, reaching a "supercritical" state, significantly improving the utilization efficiency of the calorific value. This technological breakthrough enables the efficient, stable, and clean combustion of low-calorific gas for power generation, providing a new path for emission reduction and carbon reduction in energy-intensive and high-carbon emission industries such as iron and steel metallurgy.

  In addition, the successful application of this technology has not only significantly reduced enterprise production costs and improved product quality but has also significantly reduced emissions of greenhouse gases such as carbon dioxide, injecting new vitality into the green development of enterprises. With the continuous promotion and application of this technology, emission reduction efforts in industrial furnaces and kilns will usher in a broader development prospect.
