Project Overview In 2025, a leading textile dyeing and printing factory in Kabul, Afghanistan, selected AIX Boiler to supply a complete heating solution for their high-volume fabric processing line. The factory specializes in cotton and polyester dyeing, printing, and finishing, requiring reliable, high-temperature steam and thermal oil for critical processes including scouring, bleaching, dyeing vats, stentering, heat-setting, and drying chambers.
After detailed technical evaluation and site assessment (via video call and local partner coordination), the client placed an order for:
- 1 × 15 TPH SZL Double-Drum Chain Grate Coal-Fired Steam Boiler
- Rated evaporation: 15 t/h (saturated steam at 1.25 MPa / 13 bar)
- Designed fuel: local Afghan bituminous coal (calorific value ~5,200 kcal/kg)
- Efficiency: ≥84% (with economizer and air pre-heater)
- Key features: double-drum water-tube design, wide coal adaptability, automatic chain grate, low-NOx staged combustion, baghouse dust collector for emission compliance
- 1 × 4 Million kcal/h (≈4.65 MW) Coal-Fired Thermal Oil Boiler
- Rated thermal power: 4,000,000 kcal/h
- Max. working temperature: 320°C
- Designed fuel: same local coal as above
- Key features: three-pass coil structure, forced circulation, high-temperature safety valves, expansion tank, energy-saving economizer
Project Purpose & Application
- 15 TPH SZL Steam Boiler: Supplies saturated steam to:
- Dyeing vats and jiggers (high-temperature dyeing at 130–140°C)
- Mercerizing and scouring lines
- Steam agers and curing ovens
- Boiler provides stable pressure and large steam volume to support continuous multi-shift operation.
- 4 Million kcal/h Thermal Oil Boiler: Provides high-temperature heat transfer oil to:
- Stenter frames and heat-setting machines (180–220°C for polyester fixation)
- Calendar rolls and drying cylinders
- Hot oil heating coils in drying chambers
- Ensures uniform temperature across wide fabric widths, preventing color migration and improving fabric hand feel.
Why the Client Chose AIX Boiler
- Proven reliability in high-dust, variable coal quality environments (common in Afghanistan)
- Competitive pricing combined with A-grade quality certification (China Special Equipment Manufacturing License)
- Full turnkey support: detailed drawings, local installation guidance, operator training, and 24/7 remote technical assistance
- Compliance with local environmental requirements (bag filter + low-NOx burner achieved particulate <50 mg/Nm³, NOx <300 mg/Nm³)
- Fast delivery commitment (factory production + sea freight to Karachi port + overland transport to Kabul)
Project Timeline
- Order confirmation: Q2 2025
- Manufacturing & testing: 90 days at AIX Boiler’s Taikang factory
- Delivery & site arrival: Q4 2025
- Installation & commissioning: Q1 2026 (supervised by AIX engineers)
- Full commercial operation: March 2026
Client Feedback (Post-Commissioning Summary) “The 15 TPH SZL steam boiler runs stably with our local coal, and the thermal oil system gives perfect temperature uniformity on our stenter. AIX Boiler’s after-sales support has been excellent — quick response even from China. Highly recommend for textile factories in our region.”
This project exemplifies AIX Boiler’s capability to deliver robust, coal-adapted heating solutions tailored to challenging markets like Afghanistan, helping clients achieve high productivity with controlled costs and emissions.
