1.Introduction to Control System

1.1 Temperature Control
a. Each temperature control unit is equipped with a thermocouple, a temperature controller and an electric regulating valve. The temperature control system automatically adjusts the proportion according to the temperature of the kiln.
b. There are 36 burners in the whole kiln.
c. The temperature control unit in the high temperature area is controlled by 6 sections up and down, each section has 6 muskets, 3 on the left and right, staggered and evenly distributed, and the flame is even.
d. The burner is a special high-speed burner for oxidizing flame.
1.2 Pressure Control
a. There are filters, pressure regulator valves, safety solenoid valves, high and low pressure switch alarms and pressure gauges in the gas main process, and operators can make adjustments at any time as needed.
b. The combustion-supporting fan has a pressure sensor, which is adjusted by the frequency converter to automatically adjust the set air pressure.
c. A kiln pressure sensor is installed at the junction area of the smoke exhaust section and the medium temperature section, and the exhaust fan automatically adjusts the drawing force according to the size of the kiln pressure.
d. There are 5 fire baffles in the kiln, which divide the kiln into several districts, and the pressure in the kiln is adjusted and controlled.
1.3 Atmosphere Control
a. The burner is a special burner specially designed for the proportion of oxidizing flame according to natural gas. The burner burns completely and has good energy saving effect.
b. The gas volume of the burner is controlled by the actuator.
c. The pressure assembly adjustment system ensures stable wind pressure.
d. Baffles and fire-blocking walls are provided in different areas of the kiln to form a combustion chamber to ensure that the oxidizing atmosphere meets the product firing requirements.
2. Gas Safety Measures
 2.1 Fan Interlock
 There is an electrical interlocking system between the kiln head exhaust fan → combustion fan → gas assembly solenoid valve. That is, the exhaust fan → the combustion fan → the gas solenoid valve must be turned on in sequence. If they are not turned on in sequence, the gas solenoid valve cannot be started. After the exhaust fan is turned on, a negative pressure state is formed in the furnace, and the residual gas and other waste gas in the furnace will be emptied in time. After the combustion-supporting fan is turned on, each burner will have combustion-supporting air. After the two fans are all turned on, the gas solenoid valve can be turned on to ensure the safety of the kiln ignition. When the two fans are in normal operation, no matter which fan suddenly stops, the gas main solenoid valve will immediately close the valve to cut off the gas to ensure the safety of the kiln.
2.2 Pressure Sensor
A kiln sensor is installed on the combustion-supporting fan pipeline. After the combustion-supporting fan is started, the gas solenoid valve can be activated only after the pressure sensor detects that there is pressure. Conversely, if the pressure sensor cannot detect the wind pressure, the gas solenoid valve cannot be activated.
2.3 Main Solenoid Valve and Emptying Solenoid Valve
At the end of the main gas pipe of the kiln, an automatic emptying device is installed. When the main gas solenoid valve is opened, the emptying solenoid valve will be closed immediately and no longer emptying. When the main gas solenoid valve is closed, the emptying solenoid valve immediately opens the switch to empty the room. After emptying, the main gas pipeline of the kiln will lose pressure, and no more gas will be sprayed into the furnace through the burner to ensure the safety of the kiln.
