1、 Working principle of regenerative burner: The system shall at least include two burners, two regenerative chambers, a heat recovery system, and corresponding control devices. The burner and heat storage chamber can be directly connected together according to the actual situation on site or alternatively connected together using pipes cast with refractory materials. How does a regenerative burner work? How to achieve energy-saving goals? There is a special introduction to the regenerative burner.
2、 The characteristics of the regenerative burner control cabinet designed by Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd.: The regenerative burner control cabinet uses PLC as the core device, which can achieve automatic ignition, flame size indication, automatic conversion of large and small fires, and flameout alarm functions for the burner. Its working principle is: temperature control with PID parameter self-tuning, usually maintaining a low fire and constant brightness, and each stage has different thermal requirements for the burner. The burner control system automatically adjusts the combustion capacity of the regenerative burner. Within this range, the gas and air ratio can be accurately controlled through the PID closed-loop control system. The specific control principle can be found on the official website: Regenerative Burner Control
3、 Composition of coke oven gas:
Coke oven gas, also known as coke oven gas, English name: Coke Oven Gas (COG), belongs to high heating value gas, gas or raw gas. It refers to a combustible gas produced by preparing several types of bituminous coal into coking coal, which is subjected to high-temperature dry distillation in the coking furnace, while producing coke and tar products. It is a byproduct of the coking industry.
4、 Characteristics of coke oven gas:
1. The calorific value of coke oven gas is high at 3994-4493kcal/m3, and the combustible composition is relatively high (about 90%);
2. Coke oven gas is a colorless and odorless gas;
3. Coke oven gas is toxic due to its presence of CO and a small amount of H2S;
4. Coke oven gas contains a lot of hydrogen, has a fast combustion speed, and a short flame. When designing coke oven gas burners, pay attention to this characteristic;
5. Coke oven gas contains some tar and naphthalene to prevent blockage of pipelines and fittings. If necessary, regular cleaning of burners and pipelines is necessary;
6. The ignition temperature is 600-650 ℃;
5、 Application of regenerative coke oven gas burner: ladle roaster, steel rolling heating furnace, forging heating furnace, aluminum melting furnace, scrap preheating system, etc.
