Natural gas thermal oil furnace

Natural gas thermal oil furnaceAs an efficient thermal energy conversion device, it uses natural gas or flammable liquids as fuel and thermal oil as the heat carrier. By using a circulating oil pump to force liquid phase circulation, heat energy is efficiently delivered to various heating equipment, and then returned for reheating, forming a DC working cycle. This equipment is widely used in various fields such as petrochemicals, textiles, printing and dyeing, plastics, rubber, food processing, wood processing, asphalt heating, cardboard box production, vegetable dehydration, baking paint, casting sand mold drying, etc. In addition, it can also meet the process requirements of baking, steaming, shaping, melting, drying, etc. at ≤ 350 ℃.

Natural gas thermal oil furnaceStructural features:The heating surface structure of the main body is compact, consisting of tightly arranged disks inside and outside. The inner coil serves as a radiant heating surface, effectively absorbing heat; The outer coil and the outer surface of the inner coil together form a convective heating surface, further improving thermal efficiency. The boiler is composed of an upper body and a lower combustion chamber, making it easy to assemble and install on site. After the fuel in the combustion chamber is fully burned, the high-temperature flue gas undergoes efficient heat exchange through radiation and convection heating surfaces. Then, the air required for combustion is preheated in the air preheater, treated by the dust collector, and finally sent to the chimney for discharge by the induced draft fan.

Detailed explanation of application areas

1. Chemical industry: Suitable for heating various chemical reaction processes such as distillation, evaporation, and polymerization, as well as heating synthetic devices such as pesticides and intermediates.

2. Oil industry: plays a key role in processes such as oil decomposition and fatty acid distillation.

3. Paper industry: Provide stable heat sources for equipment such as coating rollers and drying rollers.

4. Plastic and rubber industries: meet the heating needs of production processes such as hot pressing and heat extension.

5. Synthetic fiber industry: providing efficient thermal energy in processes such as polymerization and melting.

6. Fat and paint industry: suitable for heating and curing equipment such as high-pressure reactors and dryers.

7. Wood industry: Provide stable heat sources for equipment such as hot pressing and drying, and improve production efficiency.

Overview of Product Features

It consists of two core parts: the furnace body and the combustion chamber, and is equipped with heating, combustion, and electrical control systems. The heating system includes auxiliary equipment such as expansion tanks and oil storage tanks to ensure stable transmission of thermal energy; The combustion system is equipped with blowers, induced draft fans, etc. to achieve efficient combustion; The electrical control system is responsible for monitoring and operating the overall equipment.

Guidelines and Precautions for Use

1. Operator qualification: Operators need to undergo professional training and obtain corresponding certificates to ensure safe operation.

2. Operating procedures: The user unit should develop detailed operating procedures, clarify the operating procedures and precautions for start-up, operation, shutdown, etc.

3. Pipeline insulation: Insulation measures should be taken for pipelines, but flange connections should be avoided from being covered to prevent safety hazards.

4. Exhaust and boost: During the ignition boost process, multiple exhausts should be carried out to ensure that air, water, and mixed steam are completely removed; The gas-phase furnace stops exhausting after the temperature and pressure match the corresponding relationship.

5. Heat carrier management: Heat transfer oil needs to be dehydrated before use to avoid mixing different heat carriers; Regularly analyze the performance of the heat carrier and replace or regenerate it in a timely manner when it is found to be unqualified.

6. Heating surface inspection: Regularly inspect and clean the heating surface to ensure stable equipment performance; Store the inspection and cleaning results in the technical file.

7. Safety test: After installation or major repairs, hydraulic and air tightness tests should be conducted to ensure the safety and reliability of the equipment; Local boiler safety supervision personnel should participate in the supervision during the experiment.
