Indonesian Fertilizer Plant Client Visit | Technical Expertise and Delivery Capabilities Earn Recognition

A client from the Indonesian fertilizer industry recently visited SIMO Blower to conduct an on-site facility inspection and engage in technical discussions regarding potential collaboration. The proposed project involves the supply of industrial centrifugal fans for several critical process stages in a fertilizer production line, including drying, cooling, granulation, and dust removal. During the visit, the client focused on evaluating SIMO Blower’s manufacturing capabilities, machining standards, expertise in technical selection, and project delivery arrangements. Requirements for Industrial Fans in Fertilizer Production Fertilizer production involves a variety of distinct process conditions, each requiring specific airflow, pressure, and equipment configurations. During drying and granulation stages, exhaust gases may contain corrosive substances, moisture, and dust. These operating conditions impose stringent requirements on the materials used for fans, as well as on their corrosion resistance, wear resistance, and long-term operational reliability. When selecting fans for equipment that operates continuously within a production line, one must not rely solely on airflow and pressure parameters; rather, a comprehensive assessment of the actual operating conditions is essential. Key considerations include: Drying: Handling high-temperature, high-humidity, and dust-laden exhaust gases. Cooling: Providing a stable airflow to meet process cooling requirements. Granulation: Supplying process ventilation and exhaust gas treatment support in humid and dusty environments. Dust Collection: Maintaining the necessary airflow and pressure for dust collection and conveying systems. The selection of materials, protective coatings, and wear-resistant structural designs must be determined based on the gas composition, temperature, humidity, and dust characteristics specific to each application. Technical Discussions and Factory Visit During the visit, the SIMO Blower technical team engaged in in-depth discussions with the client regarding specific requirements for various process stages, identifying the key parameters that influence fan selection. The dialogue covered requirements for airflow and pressure, operating conditions, material specifications, as well as solutions for corrosion and wear resistance. The client also toured our production facilities and processing equipment, gaining a comprehensive understanding of our manufacturing processes, production organization, and quality control procedures. In addition to equipment selection, our team consulted with the client on matters such as production planning, manufacturing coordination, and project delivery schedules. By clarifying these requirements prior to contract finalization, both parties were able to identify potential technical and manufacturing considerations early on, helping to mitigate the risk of specification mismatches during the subsequent project execution phase.

ID Fan Replacement for SCR Retrofit at a Waste-to-Energy Plant

Project Background: Increased System Resistance Following SCR Installation To comply with more stringent emission standards, a waste-to-energy plant incorporated an SCR (Selective Catalytic Reduction) system as part of an upgrade to its flue gas treatment process. The addition of the SCR equipment altered the resistance characteristics of the flue gas system. Consequently, the operating conditions of the existing induced draft fan had to be re-evaluated to ensure it could meet the operational requirements of the upgraded system. Rather than selecting a replacement fan based solely on the original equipment parameters, this project sought a solution specifically tailored to the requirements of the modified flue gas system. Fan Requirements for the Upgraded Flue Gas System SIMO Blower provided a customized centrifugal induced draft fan for the flue gas upgrade project of Boiler No. 4. The primary operating parameters are as follows: Parameter Specification Fan type Induced Draft (ID) Fan Fan model 3400DWB21F Airflow 189,588 m³/h Static pressure 15,588 Pa Operating temperature 150°C Impeller diameter 3,400 mm Main motor power 2,240 kW This fan has been configured to meet the "high air volume, high pressure" requirements specified for the flue gas treatment process in this project. Its mechanical structure and auxiliary components—including bearings, temperature monitoring devices, and vibration monitoring equipment—have all been selected in accordance with the project's specific needs. Key Engineering Consideration: Recalculating Fan Operating Points Following SCR Retrofitting An SCR (Selective Catalytic Reduction) retrofit involves more than just the addition of emission control equipment; it also alters the pressure loss characteristics of the flue gas treatment system. The SCR reactor, catalyst layers, connecting ductwork, and other components can introduce additional flow resistance. The actual pressure loss depends on the specific system design and operating conditions. If the existing induced draft (ID) fan cannot accommodate the resistance of the modified system, the power plant may encounter issues such as insufficient airflow, operational instability, or the fan operating outside its design envelope. Therefore, when implementing an SCR retrofit, the selection of an ID fan must account for the entire upgraded flue gas system, including: ● Required flue gas volumetric flow rate post-retrofit ● Total system resistance and fan pressure requirements ● Operating temperatures and flue gas characteristics ● Pressure losses across ductwork and SCR equipment ● Motor power and operating conditions ● Fan construction, materials, and monitoring requirements The critical step is to determine the required fan operating point based on the upgraded system, rather than simply relying on the nameplate specifications of the existing fan.
