The engineering brief

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 SERIES 50 – 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 SERIES 500 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 SERIES 1 – 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 RETROFIT Custom 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 compatibility

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 & support

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.

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.

Proposal & sign-off

Burner spec, hopper sizing, ash handling, electricals and civils — itemised and costed. Sign and we schedule fabrication.

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.

Site install & commissioning

Our crew at your plant. Mechanical install, electricals, controls integration. Commissioning under load, with operator training.

Lifetime servicing

Annual service contract optional. Local spare parts inventory. Remote diagnostics on NT-S and NT-T. Response targets in your SLA.

Technical specs

All four series
at a glance.

Series	Output	Efficiency	Temp range	Best for
NT-B	50 – 500 kW	90 %	Hot water / low-pressure steam	Bakeries, hotels, light industry
NT-S	500 kW – 2 MW	92 %	Steam ≤ 12 bar / 220 °C	Textile dyeing, food processing
NT-T	1 – 5 MW	93 %	Thermic fluid ≤ 320 °C	Plastics, chemicals, asphalt, large processes
NT-R	Match host	+12 % vs host	As existing boiler	Diesel & coal retrofit
