Regenerative waste gas incinerator burner: automatic temperature control and remote DCS control

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 keeping the small fire constant, and the thermal requirements of the burner are different at each stage of each furnace. The burner control system automatically adjusts the combustion capacity of the regenerative burner. Within this range, the PID closed-loop control system is used to accurately control the gas and air ratios. The specific control principle can be found on the official website: Regenerative Burner Control Cabinet

3、 Overview of Incinerators: Incinerators can be divided into gas waste gas incinerators, oil waste gas incinerators, and regenerative waste gas incinerators based on the different fuels used.

Overview of the working principle of exhaust gas incinerator: It utilizes the heat generated by auxiliary fuel combustion to raise the temperature of combustible and harmful gases to the reaction temperature, thereby causing oxidation and decomposition. Waste gas incinerator is suitable for the treatment of waste gas from spraying and drying equipment, as well as the purification of harmful gases emitted by industries such as petrochemicals and pharmaceuticals. The gas purification of water-soluble or viscous substances and polymer substances in organic waste gas shows its advantages. Meet environmental and labor protection requirements, while adding heat exchange equipment to achieve the goal of waste heat reuse and energy conservation.

4、 The key components of the waste gas incinerator - burner - are divided into gas burner, fuel burner, and combustion control system based on the fuel used. The incinerator is a furnace lined with high alumina refractory material on the inner wall, with oxygen supply holes designed around it to better contact the exhaust gas with the air. The incineration is designed according to the three T principles (temperature, time, and eddy current). After the exhaust gas enters the incinerator, the combustion flame rotates along the main combustion cylinder of the furnace body at a speed of 2-3 meters/second, and moves axially along the furnace body at a speed of 2-3 meters/second, greatly extending the residence time of the exhaust gas in the high-temperature flame zone, The strong pressure air velocity of 2-3 meters/second forms an intertwined closed firepower network, allowing the flame vortex to fully burn. Then, the toxic and harmful components in the flue gas are removed by the spray absorption tower, and the exhaust gas is discharged into the atmosphere through the chimney.

In addition, Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd. undertakes the overseas project of diesel heavy oil and gas generator waste gas incinerator equipment. For more information, please feel free to call (WeChat synchronization): 15713691937.
