What is a pulverized coal burner for heating furnace and rotary kiln
Pulverized coal burner refers to equipment that can fully ignite pulverized coal in a short period of time, causing high-temperature vortex. According to the main purpose, pulverized coal burners are divided into:
1. Special type pulverized coal burner for cement rotary kiln;
2. Pulverized coal burner for heating furnace;
3. Special pulverized coal burner for asphalt mixing station.
The pulverized coal burner has a multi-level plug exhaust oriented structure with a unique design scheme, which can cause the pulverized coal to cause a high-temperature vortex in a short period of time. It has complete ignition, high heat utilization, sales of smoke and ash, high efficiency, environmental protection and energy saving. Improving the standards at work and alleviating the advantages of labor efficiency are ideal products for green and environmental protection. The high-efficiency ignition technology of pulverized coal and the low-NOx ignition technology are two different technologies. Reducing the conversion of NOx and pollutant emissions depends on the control and ignition area. The temperature should not be too high, but the ultra-low temperature ignition harms the ignition rate of pulverized coal. The two technical applications are harmoniously used to achieve the best comprehensive practical effect. In fact, it is stipulated to control the process of pulverized coal burning. It can not only ensure the reliability of the pulverized coal fire, but also have a lower ignition temperature, and in addition, there is a sufficient long ignition time at a certain temperature to ensure the burning of embers.
1. The luminosity of the smoke and dust discharged from the pulverized coal burner is Ringelmann 0-1;
2. The fixed carbon content of desulfurized gypsum in the pulverized coal burner is around 0.1%, and the foundation has no carbon powder;
3. The environmental protection and energy saving ratio of the new pulverized coal burner is 15-30%;
4. The smoke and dust components in the combustor are changed to the lower exhaust flue under the condition that there is no dust removal device in the exhaust flue. If the wind coal is sufficiently ignited, the national industry standard can be achieved.
