Coal-Fired Thermal Oil Boiler Project for a Printing and Textile Dyeing Company in Nigeria

Project Overview

Kano State, Nigeria, is a major center for the textile and dyeing industry in West Africa. A large local printing and textile dyeing enterprise is one of Nigeria’s primary production bases for all-cotton wax-printed fabrics, with products exported to multiple countries in West Africa. Thermal oil boilers are critical equipment in the printing and dyeing industries, providing stable high-temperature thermal energy for processes such as hot-melt curing, high-temperature steaming, drying, and finishing.

Based on its positive experience from previous collaborations with Huano Boilers, the company has full confidence in Huano’s product quality and safety and has once again chosen to partner with Huano.

Solution

In response to the enterprise’s stringent requirements for temperature stability in processes such as hot-melt curing and high-temperature steaming, Huano Boilers’ technical team provided a YGW-3000MA horizontal coal-fired thermal oil boiler:

Request a Solution

High-efficiency, energy-saving furnace design

The boiler features an optimized furnace arch structure and a multi-pass heat exchange design, providing ample heat transfer area. This enables rapid heating of the thermal oil and high heat transfer efficiency, effectively reducing coal consumption and delivering significant energy savings.

Intelligent Control for Stable Heat Supply

The boiler employs a fully automated operation control system that automatically adjusts combustion intensity based on process load, ensuring minimal fluctuations in thermal oil temperature and stable heat supply—perfectly meeting the continuous production requirements of the printing and dyeing industry.

Safe, Reliable, and Easy to Maintain

With multiple safety interlock protections and a user-friendly interface, local operations and maintenance personnel can operate the system independently after only a short training period, ensuring the long-term safe and stable operation of the equipment.

Core Project Advantages

Coal consumption is significantly reduced, fuel costs are effectively controlled, and operational efficiency is greatly improved.

Stable thermal oil temperature leads to steady improvements in product quality for key processes such as hot-melt curing and high-temperature steaming.

Safe and reliable equipment operation ensures full-capacity production during peak seasons.

Client Testimonial

“Choosing Huanuo Boilers again was a wise decision! As a major local production base for wax-printed fabrics, processes such as hot-melt curing place extremely high demands on thermal energy. This thermal oil boiler operates stably and reliably, and we are very satisfied.”

Ibrahim Musa

Head of Production

“Huanuo’s SZS series steam boiler has performed very stably on our continuous paper production line. The steam pressure fluctuation is minimal, fully meeting the high-quality steam requirements of the drying cylinders. After more than a year of operation, it has maintained high thermal efficiency and a low failure rate—one of the most reliable pieces of equipment on our line.”

Budi Santoso.

Equipment Manager, a major paper group in Indonesia

“Pharmaceutical processes have extremely high requirements for steam cleanliness and temperature control. Huanuo’s electric steam boiler produces clean steam with no on-site emissions and provides precise temperature control. It helped us smoothly pass several international quality system audits. It is a boiler that truly understands the needs of the pharmaceutical industry.”

“Our hotels have very high requirements for the quietness and safety of hot water supply. Huanuo’s vacuum hot water boiler operates very quietly and maintains a stable water temperature—guests hardly notice the equipment is there. Since the upgrade, hot water complaints have dropped significantly, and management has become much easier.”

Ahmed Hassan.

Head of Engineering, a hotel group in Egypt

“The stenter machines in our dyeing and finishing process are very sensitive to thermal oil temperature stability. Huanuo’s thermal oil heater heats up quickly with minimal temperature fluctuation, and the finishing effect has improved noticeably. Fuel consumption is also considerably lower than that of the original equipment. Their after-sales service responds promptly, making the cooperation very smooth.”

Production Manager, a textile dyeing and finishing company in Türkiye

“Our washing workshop requires frequent steam on/off cycles and has limited space. Huanuo’s once-through steam boiler occupies a small footprint and produces steam within 2 to 4 minutes, fully keeping up with our pace. The steam is stable and operation is simple—very suitable for our high-intensity washing conditions.”

Operations Supervisor, a garment washing company in Bangladesh

“Food processing has strict requirements for both steam quality and emissions. Huanuo’s condensing steam boiler has high thermal efficiency and a low exhaust gas temperature, with NOx emissions far below local standards. It helped us easily pass environmental reviews, while natural gas costs have also dropped noticeably.”

Khalid Al-Farsi

Plant Manager, a food processing plant in Saudi Arabia

“We use local agricultural and forestry residues as boiler fuel. Huanuo’s biomass steam boiler has strong fuel adaptability and runs stably, which not only reduces fuel costs but also eases solid waste disposal pressure. Emission indicators meet local environmental requirements, and the overall benefits have exceeded expectations.”

Johan van der Merwe

Energy Manager, a beverage producer in South Africa

“Chemical plants have extremely high requirements for heat source continuity. The waste heat boiler customized by Huanuo fully recovers waste heat from process tail gas and produces steam stably, significantly reducing the cost of purchased steam. Since commissioning, the equipment has operated reliably and provided real help for our energy-saving and consumption-reduction efforts.”

Rajesh Kumar

Technical Director, a chemical company in India

“Our region has long winters and extremely low temperatures, so heating equipment must withstand severe conditions. Huanuo’s hot water boiler starts quickly and supplies heat stably even in low-temperature environments. Throughout the entire heating season, there were no unplanned shutdowns, and our residential heating guarantee capability has improved markedly.”

Dmitry Ivanov

Operations Manager, a district heating company in Russia

“Our exported fruits and vegetables have very high requirements for drying color and moisture content. Huanuo’s hot air furnace provides precise temperature control and clean hot air. After drying, the fruits and vegetables retain a natural color and stable quality, fully meeting export standards. Energy consumption is also lower than that of the original equipment, giving us more reliable capacity during peak season.”
