Product description

1. The overall outer frame is made of carbon steel material, which has high heat resistance and wear resistance, extremely strong oxidation resistance, and higher hardness. The surface adopts plastic spraying technology, which is not easy to rust, has a long service life, and the coating surface has the characteristics of bright color, safety and reliability, and strong adhesion.

2. The inner chamber of the kiln adopts the structure of mullite brick JM-26, lightweight ball brick, and heavy high alumina brick: (high temperature resistance, up to 1400 ℃ or above, room temperature compressive strength 2Mpa, good thermal shock resistance, and improved insulation efficiency)+high-temperature cotton (aluminum silicate refractory fiber woven blanket), with mullite arch design on the top of the furnace for more even heat circulation.

3. Ignition system: equipped with high-speed firing, each burner has functions such as automatic flame detection, extinguishing alarm and cutting off gas, automatic temperature control, automatic control of large and small fires, and manual switching between high and low fires.

4. Gas safety system: equipped with safety shut-off valve and safety release valve. In case of power outage, gas pressure overpressure or low-pressure, or failure of combustion and smoke exhaust fans, the electromagnetic safety shut-off valve will immediately automatically cut off the gas supply, and the safety release valve will release overpressure.

5. Combustion/cooling air system: adopts variable frequency control regulation, and each group is equipped with an actuator to participate in automatic control of single point proportional adjustment, ensuring the atmosphere and temperature requirements inside the kiln.

6. Smoke exhaust system: adopts mechanical automatic smoke exhaust, controlled by fan frequency converter, to regulate the smoke flow rate and kiln pressure. The smoke exhaust main pipeline is equipped with thermocouples to monitor temperature to protect the fan, and after heat exchange, it is directly discharged into the desulfurization tower for environmental protection treatment of waste gas.

7. Power control: Adopting MCGS touch screen computer centralized non-interference control method, automatic control of temperature, pressure, atmosphere and other curves is achieved through control software programming. Equipment such as fans, actuators, solenoid valves, ignition controllers, etc. operate and alarm interlocking control.

8. The main functions of the operation station system are to set and manage the temperature curve (temperature range point values, alarm limits), combustion pressure curve, smoke exhaust kiln pressure curve, and time period curve of the process formula curve, to meet different process technical requirements.

9. Safe operation guarantee: (1) Equipment operation safety interlock; (2) Accidental shutdown and gas interruption of any burner; (3) Gas pressure exceeds the limit and cuts off gas; (4) Automatic detection of power failure; (5) Real time detection of thermal control parameters.
