Brictec ISG/ASG High-Speed Natural Gas Burner The Brictec ISG high-speed burner is equipped with automatic ignition and flame detection. It features intelligent automation control, excellent stability, and a wide power regulation range, operating effectively at any temperature. With automatic ignition and temperature control functions, it is an essential ignition device for external-firing tunnel kiln natural gas burner systems and automatic ignition systems. Each burner is equipped with an independent control cabinet, automatic ignition, flame detection, and flue gas fan signal monitoring for safety. The ISG burner eliminates unburned gases inside the tunnel kiln, improving combustion efficiency and reducing harmful emissions. ISG Burner / Technical Parameters: Parameter Specification Applicable Fuels All gaseous fuels (Natural gas, Butane, Propane) Gas Pressure 0.2 – 0.36 bar Heat Power 60 – 150 kW Ignition Method Electrode ignition Operating Modes Max / Min / Stop Flame Detection Ion probe Installation Kiln top or side ASG Burner / Technical Parameters: Parameter Specification Applicable Fuels All gaseous fuels (Natural gas, Butane, Propane) Gas Pressure 0.2 – 2 bar Heat Power 40 – 70 kW Ignition Method None Operating Modes ON – OFF Installation Kiln top 2. Brictec ASNG/2 Dual-Fuel Heavy Oil & Gas Burner The ASNG/2 burner can operate with either liquid fuels (heavy oil, light oil, crude oil, biofuels) or gaseous fuels (natural gas, butane, propane). Switching between fuels requires only a simple switch, no replacement of the burner. A daily oil tank, installed near the kiln, heats and circulates fuel, ensuring continuous flow and avoiding blockages due to low temperature. All tanks are equipped with heaters, safety floats, and necessary accessories for safe and efficient operation. ASNG/2 Burner / Technical Parameters: Parameter Specification Applicable Fuels Liquid: Heavy oil, Light oil, Crude oil, BiofuelsGas: Natural gas, Butane, Propane Gas Pressure 0.2 – 2 bar (for gas) Heat Power 40 – 70 kW Ignition Method Variable (for oil); ON–OFF (for gas) Operating Modes Variable speed (oil) / ON–OFF (gas) Installation Kiln top 3. Brictec PCS Pulverized Coal Burner The Xi’an Brictec PCS pulverized coal burner is an energy-saving, efficient, and simple device used for coal pulverization and feeding in ring kilns and tunnel kilns. It integrates crushing raw coal to below 200 mesh, automatic feeding, and coordination with the temperature control system for fully automated production. PCS Burner / Technical Parameters: Parameter Specification Applicable Fuels Pulverized coal (≤5 mm, Moisture ≤5%, Sulfur ≤4%, HGI ≥50, Calorific value ≥6000 Cal) Heat Power 115 kW per point (max 12 points) Feeding System Automated feeding Installation Tunnel kiln / Ring kiln  

Discussion on Pressure Regime in Brictec Tunnel Kiln Firing During tunnel kiln firing, the rationality of the pressure regime has a significant impact on firing results. The kiln pressure regime refers to the distribution pattern of static pressure along the length of the tunnel kiln. By plotting the pressure data of different car positions, a “pressure curve” is obtained. The pressure regime directly determines the flow state of gases inside the kiln, which in turn affects: 1. Heat exchange in the kiln; 2. The amount of combustion air required and the exhaust gas discharged; 3. The uniformity of pressure and temperature distribution inside the kiln.   I. Formation of the Pressure Regime The pressure distribution inside the kiln is the result of multiple gas flows acting together: 1. Cooling zone: A large amount of cold air enters, while heated air is extracted. 2. Firing zone: Fuel combustion generates gases, with the addition of primary air and atomized fuel. Pressure in this zone is usually higher than atmospheric pressure, forming positive pressure. 3. Preheating zone: A large amount of flue gas and water vapor is discharged by the exhaust fan. Kiln pressure is lower than atmospheric pressure, forming negative pressure. During the transition from positive pressure to negative pressure, there exists an interface where the internal kiln pressure equals the external atmospheric pressure. This is called the zero-pressure plane (or zero point/zero position). (1) Before the zero-pressure plane (preheating zone) → Negative pressure zone, beneficial for discharging flue gas and water vapor, but may cause cold air infiltration, leading to thermal stratification and increased temperature difference. (2) After the zero-pressure plane (firing zone) → Positive pressure zone, prevents cold air entry and maintains stable, uniform temperature. II. Control of the Zero-Pressure Position In practical operation, most tunnel kilns maintain the firing zone under slight positive pressure, and set the zero-pressure plane at: 1. The middle of the firing zone; 2. Or around 1/3 of the coal-feeding rows toward the insulation zone; 3. Or slightly behind this position. This allows high-temperature gases to evenly fill the entire brick stack, ensuring uniform heating and insulation of bricks at high temperatures. III. Key Points for Controlling Positive Pressure 1. Advantages of moderate positive pressure: Stable kiln atmosphere, uniform temperature, prevention of cold air entry. 2. Risks of excessive positive pressure: Significant hot gas leakage → increased heat loss; 3. If kiln car bottom sealing is insufficient → hot gases flow downward, possibly leading to: (1) Deformation and damage of kiln car skirts; (2) Wear of sand seal grooves; (3) Evaporation of bearing lubricating oil, causing bearing damage; (4) Deterioration of the working environment. Therefore, tunnel kiln operation should avoid excessive positive pressure and maintain only slight positive pressure.
