Moulded shell baking furnace burner: regenerative combustion technology is more energy-saving

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

3、 Classification of shell baking furnace: shell baking furnace can be divided into regenerative shell baking furnace and tunnel shell baking furnace according to furnace type. Trolley shell baking furnace is mainly used for silica sol shell baking. Furnace temperature: 1150 ℃. The tunnel type mold shell roasting furnace is mainly used for baking water glass mold shells, with a furnace temperature of 850-920 degrees.

2、 Characteristics of the core component of the regenerative shell baking furnace - regenerative burner:

1. Energy saving. The mold shell baking furnace burner adopts the Zhongwei brand regenerative burner, which is energy-saving, low nitrogen, and environmentally friendly.

2. Regenerative burner control cabinet. The burner of the mold shell baking furnace is equipped with automatic ignition, flameout protection cut-off, and temperature zone control to ensure the uniformity of preheating, heating, and insulation temperatures, prevent mold shell from overheating, and is equipped with a recorder to constantly monitor the temperature difference inside the furnace.

3. The shell baking furnace adopts ignition * control system, leakage protection system, pressure control system, etc.

4. The gas sources of the calciner for water glass mold mainly include natural gas, compressed natural gas (CNG), liquefied natural gas (LNG), liquefied petroleum gas (LPG), and other gases include blast furnace gas, coke oven gas, etc. For details, please call (WeChat synchronization): 15713691937
