Energy saving regenerative gas baking device suitable for baking steel ladle, molten iron ladle

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, digital control of the gas air mixture ratio is achieved through the PID closed-loop control system. The specific control principle can be found on the official website: Regenerative Burner Control

3、 There are usually two types of baking machines: sleeve type and metal preheating type, both of which have problems such as high energy consumption, long baking time, low baking temperature, and high exhaust temperature. The new regenerative baking device designed by Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd. adopts a closed baking method and utilizes a high-frequency directional valve to alternately pass through the furnace flue gas, combustion air, and gas in the heat storage body, providing sufficient heat exchange between each other to preheat the combustion air and gas to around 1000 ℃, increasing enthalpy and achieving stable and energy-saving combustion.

1. The equipment of the regenerative baking device includes a heat storage burner, a two position four way directional valve, a bag cover, and related auxiliary equipment. Its unique structure can recover the sensible heat in the discharged flue gas, reduce the heat loss of exhaust smoke, and improve the thermal efficiency of the baking machine.

4、 Compared to ordinary baking machines, regenerative baking machines have the following main advantages:

1. Fuel saving:

By using regenerative combustion technology, the exhaust temperature of the baking machine has been reduced by about 850 ℃. According to thermal balance calculation, the fuel saved is about 50% or more.

2. Increase ladle temperature:

By injecting heat into the ladle through a regenerative burner, the temperature of the ladle can be increased, thereby reducing the tapping temperature of molten steel and reducing steelmaking energy consumption. When casting at a low tapping temperature of molten steel, high-speed billet drawing can be achieved, reducing steel leakage accidents, eliminating steel leakage accidents, eliminating shrinkage cavities, and improving billet quality.

3. Shorten baking time and improve lining life:

The use of a regenerative combustion nozzle improves the thermal energy utilization rate of the fuel, thereby increasing the average flame temperature inside the bag and accelerating the baking speed. Due to the increase in temperature inside the package and the improvement in uniformity, the temperature of the package lining is more uniform, avoiding local high temperature areas, and thus increasing the service life of the package lining by about 15%.
