pulverized coal lance
Stabilizing and increasing coal injection volume is an effective way to reduce costs in the ironmaking industry. Using 2520 heat-resistant steel and wear-resistant high-temperature blast furnace pulverized coal ceramic spray guns not only greatly extends the service life of the spray guns, but also effectively protects the tuyeres, providing strong conditions for reducing blast furnace downtime. The technological innovation involved plays a pivotal role in achieving high blast temperature, oxygen enrichment, and large-scale coal injection in blast furnaces.
I. The Process Soul of Pulverized Coal Spray Guns
The main body of the spray gun is made of indestructible 2520 heat-resistant steel, and ceramics are locally inlaid on the inner wall of its internal steel pipe. This is not only a sophisticated industrial manufacturing process, but also a revolutionary improvement in ironmaking technology.
II. The Application Advantages of Pulverized Coal Spray Guns
Its long service life and low replacement rate reduce workers' labor intensity; the stable gun position design reduces blast furnace downtime, thereby improving production efficiency. More importantly, it can stabilize and increase the coal injection volume, achieve large-scale coal injection, bringing tangible cost reductions for ironmaking enterprises. The repairability of this type of spray gun further extends the overall service life of the spray gun.
The PQ-2000 blast furnace pulverized coal spray gun is like a sharp sword, specially designed for blast furnace pulverized coal injection. Its structure is simple yet exquisite, and operation is convenient yet efficient. The design of the multi-hole gun head cleverly divides the pulverized coal airflow into several thin streams, which mix quickly with the blast furnace hot air, enabling full combustion of the pulverized coal. This not only improves the utilization rate of pulverized coal, but also brings higher economic benefits to enterprises.
During the ironmaking process, this "sword" is accurately inserted into the furnace body. When the blast furnace needs pulverized coal, the spray gun can quickly and accurately inject pulverized coal to meet production requirements; when the blast furnace does not need it temporarily, the ball of the ball valve automatically resets, ensuring that the high-temperature gas in the furnace does not leak out, building a solid barrier for production safety. Despite its high reliability and stability, regular inspection and maintenance are still required when facing emergencies to ensure that it is always in the best working condition.
In summary, through technological innovation and equipment upgrading, we have not only improved the stability and efficiency of coal injection, but also brought new vitality to the ironmaking industry. This is not only a victory of technology, but also a crystallization of human wisdom and efforts.
