Iraq Najimadin Heavy Oil Burner Project Case

I. Project Overview

The Iraq Najimadin project is located in Sulaymaniyah Province, Iraq. Undertaken in 2023, the project’s full name is the Iraq Najimadin Project. It is a key local building materials production project, focusing on large‑scale production of blocks and hollow bricks, and is committed to raising the level of automation and production capacity in the local building materials industry, thereby supporting the development of the regional construction sector.

The project is planned and designed as a 750 TPD brick plant. It adopts modern, automated production configurations, achieving fully automated control from drying and firing to finished product handling and packaging. This ensures both production efficiency and operational stability, as well as product consistency. Xi’an Brictec (Brictec), with its mature tunnel kiln combustion system technology and extensive overseas project experience, supplied combustion equipment matched to the project’s tunnel kiln, helping the project achieve standardized, large‑scale production that meets the development needs of the local building materials market.

II. Core Project Parameters and Equipment Configuration

Positioned around large‑scale production, the project is equipped with an advanced tunnel kiln, drying system, and automated production equipment. The core configuration and production parameters are as follows. All descriptions are based on the project’s actual design standards and do not include efficacy claims.

Project name: Iraq Najimadin Project

Kiln type: Tunnel kiln with design dimensions 164.45m × 9m × 1.95m. Actual internal width is 9m, length 165.45m. The kiln structure is scientifically designed with sufficient firing space, suitable for continuous large‑scale production. The kiln car height is designed to be approximately 1800mm, allowing stacking of 9 layers of 200mm‑high blocks, effectively supporting the planned production capacity.

Drying system: Equipped with six automatic continuous tunnel dryers, each approximately 112m in length, together with 152 servo fans. The fans are installed on both sides of the kiln car line, effectively avoiding the adverse effects of hot, humid air on the dryer, motor, and reducer that would occur if the fans were installed on the top outside the dryer. This extends equipment service life and ensures stable drying operation.

Production capacity: Daily output of 750 tons, meeting the planned design requirements of the 750 TPD brick plant. The large‑scale production capacity can satisfy the building material supply needs of the local and surrounding areas.

Product specifications: Main product size 400×200×200 mm, also available in 240×115×75 mm. With the existing production equipment, auxiliary products of 200×400×400 mm and 200×200 mm hollow bricks can also be produced, offering a rich product range suitable for diverse building application scenarios.

Combustion system configuration: The tunnel kiln burners use LPG and heavy oil as fuels, meeting the requirements of the tunnel kiln firing process. Fuel supply is flexible, allowing reasonable switching based on local fuel availability, balancing practicality and economy. The heavy oil burners are specially designed to handle the viscosity characteristics of heavy oil, ensuring stable and orderly combustion.

Automation configuration: The tunnel kiln is fully automatic, with kiln doors and kiln cars both under fully automatic control, reducing manual intervention. Kiln car loading/unloading and the packaging line are designed to automatic standards, achieving automated operations from green brick handling to finished product packaging. This improves production efficiency, reduces manual labor intensity, and ensures the standardization and stability of the production process.

III. Project Outcomes

The core strength of this project lies in the deep integration of large‑scale layout and automation. The rational equipment layout and process design effectively improve production efficiency and equipment operation stability. The configuration of six automatic continuous tunnel dryers with 152 servo fans, combined with a scientific fan installation arrangement, effectively avoids the damage to equipment caused by hot, humid air, ensuring stable drying operation. The fully automatic tunnel kiln and the loading/unloading and packaging systems enable fully automated control throughout the process, helping the project achieve standardized production.

The dual‑fuel (LPG and heavy oil) combustion mode adopted by the project matches the local fuel supply characteristics, balancing practicality and economy. The heavy oil burners are adapted to the characteristics of heavy oil, ensuring stable combustion and helping the tunnel kiln achieve uniform firing, thereby supporting stable product quality.

As an important cooperation project for Xi’an Brictec in the Iraqi market, the successful progress of the Najimadin project not only demonstrates Brictec’s technical adaptability in tunnel kiln combustion systems and its ability to deliver overseas projects, but also provides a large‑scale, automated building materials production solution for the local area, supports the upgrading of the local building materials industry, and further expands the influence of the Brictec brand in the Middle East market. This lays a solid foundation for deepening future China‑Iraq building materials technology cooperation and for implementing the “Belt and Road” initiative.
