BURNER CASE

A certain special steel company in Hami, Xinjiang, has a rotary kiln production line with a diameter of 4.5×65m. This is an active lime production line with a daily output of 800 tons, using blast furnace gas and pulverized coal as fuel.

In March 2025, the company successfully replaced its original equipment with a five-channel coal and gas co-combustion burner from Xiangyang Zhonghe M&E.

Previously, the special steel company to use coal, gas burner, it is in the process of production of a series of problems: the flame shape adjustment difficulties, leading to poor combustion efficiency and coal consumption is high; The thermal engineering system fluctuates greatly, which in turn affects the output and quality stability of the products.

According to these production bottleneck, Zhonghe M&E response to send technicians to the scene, insight into the roasting process, the production precise equipment parameters.

Through communication with the customer's technical team and in combination with actual usage requirements, key data was obtained, and an upgraded and optimized design was carried out to tailor an SR7-MQ/T multi-channel burner suitable for this production line.

After six months of stable operation, the effect significantly.

Improve output: nissan stability in 830 t/d, to effectively improve production capacity.

Energy consumption: pure coal consumption down 5 kg/t - ash than before; Under the condition of the same gas consumption (10,000 cubic meters of gas), the coal consumption during co-combustion is reduced by 30kg/t- ash, effectively lowering the production cost.

The flame optimization: well-shaped, strong vitality, provides a stable and efficient heat energy support for production.

Zhonghe M&E helps customers to solve production problems in xinjiang, improve production benefit.
