I would like to ask how a diesel hydrogenation heating furnace is upgraded for increased capacity

There are generally two methods for capacity expansion and retrofitting of diesel hydrotreating heaters: increasing the number of furnace tubes and improving the efficiency of the equipment. Based on your description, increasing the production capacity of the heating furnace from 800,000 tons per year to 1 million tons per year by adding only two furnace tubes suggests that the first method was used. Increasing the number of furnace tubes is a common method for capacity expansion upgrades. The furnace tube is one of the main components in a heating furnace used for heat transfer. By increasing the number of furnace tubes, the heat exchange area of the heating furnace can be increased, thereby enhancing its capacity and output. The specific procedure is generally as follows: 1. Select an appropriate location within the existing heating furnace and determine the layout plan for the two new furnace tubes to be added. 2. Conduct engineering design, including the dimensions of the furnace tubes, connection methods, support structures, etc. 3. Purchase or customize new furnace tubes, and carry out installation and connection. 4. Debug and optimize the new furnace tubes to ensure their proper operation. 5. Test and verify the new furnace configuration to ensure it can achieve the desired output and performance. It should be noted that the capacity expansion and renovation of diesel hydrogenation heaters involve certain engineering design and technical operations, which require professional engineers and technicians to plan and carry out. It is recommended to consult with relevant professional agencies or manufacturers before carrying out the modifications, to ensure a smooth modification process that meets safety and quality standards. .

The steps for upgrading the capacity of a diesel hydrogenation heater are as follows: Calculate the gap between the heater’s current capacity and the capacity required after the upgrade. This may require reference to past production data and future production plans. Determine the additional calories needed based on the gap. This may involve evaluating the thermal efficiency of existing equipment to determine the maximum possible increase in heat output. Design a new heating furnace. This may require selecting a new burner, increasing the number of heat exchangers or changing their layout, enlarging the furnace size, etc. Construct new heating furnaces. This may include purchasing and processing new components, assembly, testing, etc. Install a new heating furnace. This may require placing the new furnace on the existing equipment frame, or redesigning the equipment frame to accommodate the new furnace. Debug and test the new heating furnace. This may include checking the heat output, checking the operation of the burner, and checking the thermal efficiency of the heat exchanger, etc. Start and operate the equipment. This may include gradually increasing the operating temperature of the furnace, gradually increasing the production load, etc. Conduct operation monitoring and maintenance of the equipment. This may include regularly checking the operating temperature of the heating furnace, examining the thermal efficiency of the heat exchangers, and performing regular maintenance on the equipment. The above steps are based on general engineering practices; adjustments may be necessary depending on the specific circumstances during implementation. It is recommended to consult a professional engineer or manufacturer before making any modifications to obtain more detailed and accurate information.
