The engineering briefBuilt for biomass.
Built for biomass.
Calibrated for output.
Off-the-shelf coal and diesel burners aren’t tuned for pellet fuel. The fines accumulate. The ash chemistry slags up heat exchangers. Combustion efficiency drops. We engineered our burner range from the inside out — primary, secondary and tertiary air staged for biomass, firebox geometry matched to pellet flame profile, ash removal automated.
The result: drop-in retrofit kits that swap into existing boiler systems with minimal civils work — and stand-alone units engineered for the next 25 years of process heat.
Burner types
One range. Four use cases.
NT-B SERIES50 – 500 kW
Compact biomass burner
For small commercial heating, bakeries, dairies and small textile units. Single-stage pellet feed, auto-ignition, modulating output.
- · Footprint: 1.2 × 0.8 m
- · Integrated hopper, 200 kg capacity
- · Touchscreen controls, BMS-ready
NT-S SERIES500 kW – 2 MW
Industrial steam boiler
Three-pass shell boilers for steam-driven process heat. Textile dyeing, food processing, oil refining.
- · Saturated or superheated steam options
- · Up to 12 bar working pressure
- · Automated ash removal, screw conveyor
NT-T SERIES1 – 5 MW
Thermic fluid heater
High-temperature oil heating for plastics, chemicals, asphalt and large-scale processing.
- · Outlet temp up to 320 °C
- · Coil-in-coil design, low pressure drop
- · Multi-zone air staging
NT-R RETROFITCustom fit
Diesel & coal retrofit
Conversion kits engineered for your existing furnace. Keep the boiler, swap the burner — typical conversion: 7–14 days.
- · Site survey + thermal balance audit included
- · Burner, hopper, feeder, controls — bundled
- · Commissioning and operator training
Pellet compatibilityTuned for our
Tuned for our
own fuel.
Every NatureTech burner is calibrated on NatureTech pellets. Same supplier, same datasheet — which means combustion curves are predictable from commissioning forward.
Burners are also rated for third-party EN+ A1 pellets and for our high-husk pellet variant. Multi-fuel operation is supported on NT-S and NT-T series with field-tunable air-fuel ratios.
| Fuel | Calorific value | Compatibility |
|---|---|---|
| NatureTech EN+ A1 | 4,800 kcal/kg | OPTIMAL |
| Other EN+ A1 pellets | 4,600–4,800 | SUPPORTED |
| Rice husk pellets | 3,200 | NT-S, NT-T |
| Wood chips | 2,600 | NT-T ONLY |
| Coal blend (transition) | 4,500 | RETROFIT MODE |
Installation & supportFrom audit to
From audit to
lifetime servicing.
We don’t drop ship hardware and leave. The burner ships with a NatureTech commissioning engineer. And it stays in service with our parts inventory and field crew.
01
Site audit & thermal balance
Our engineer surveys your existing fuel chain, boiler condition and plant load. Output: a feasibility report with conversion CAPEX and payback model.
02
Proposal & sign-off
Burner spec, hopper sizing, ash handling, electricals and civils — itemised and costed. Sign and we schedule fabrication.
03
Fabrication & FAT
Built and tested in our Karachi facility. Factory acceptance test on actual pellet fuel, with you on the floor or via video walkthrough.
04
Site install & commissioning
Our crew at your plant. Mechanical install, electricals, controls integration. Commissioning under load, with operator training.
05
Lifetime servicing
Annual service contract optional. Local spare parts inventory. Remote diagnostics on NT-S and NT-T. Response targets in your SLA.
