NEO MAKİNA ve MÜHENDİSLİK A.Ş. supplies industrial pellet burner systems that convert existing solid, liquid and gas-fired boilers to wood pellets. With automatic ignition, electronic combustion control and screw feeding, pellet burners provide low-cost, carbon-neutral heat for everything from residential boilers to industrial steam and hot-water boilers, greenhouses and dryers.
What Is a Pellet Burner and How Does It Work?
A pellet burner mounts on the boiler's existing burner flange, carries pellets to the combustion head by screw, ignites them automatically and burns them with fan-controlled air. When the boiler reaches set temperature the burner modulates down or shuts off, and re-ignites automatically when heat is needed again.
Operating Principle
- Automatic ignition: An electric igniter lights the pellets within minutes; the flame is monitored by photocell.
- Modulating combustion: The controller adjusts pellet dosing and fan speed in steps according to boiler and flue-gas temperature.
- Condensation protection: Flue-gas temperature is kept above 100 °C at low load to prevent tar and acid condensation.
- Automatic cleaning: Pneumatic or mechanical combustion-head cleaning; ash emptying interval 7–30 days depending on fuel quality.
- Energy management: Priority heat-source selection using buffer tank, solar collector and boiler sensors (TS, TV, TK, TSV); AC07X-type control unit.
System Components
- Burner body: Stainless steel combustion head, igniter, fan and control board.
- Feed screw: A25 series (Ø75 mm, 1.5–2.5 m) and A45 series (Ø80–90 mm, 1.7–5 m) shaftless conveyors; drop tube against burn-back.
- Pellet silo: From 300 L day hopper to tonne-scale fabric or steel silos; pneumatic filling option.
- Control unit: Error-code display, electrical component test, automatic troubleshooting, remote monitoring.
Advantages
- Low fuel cost: Pellets are cheaper per kWh than natural gas and fuel oil; a domestic, renewable fuel.
- Easy conversion: The existing boiler is retained; installation with a flange adapter takes a few days.
- High efficiency: 92–95% combustion efficiency with quality (ENplus A1) pellets; low ash (0.5–1%).
- Low emissions: Carbon-neutral biomass; low CO and particulates.
- Fully automatic operation: Comfort close to a gas boiler; minimal operator intervention.
Typical Application Range
- Thermal capacity: 20 kW – 2,000 kW (single burner); higher with multiple burners
- Fuel: Ø6–8 mm wood pellets (ENplus A1/A2); pneumatic-cleaning version for lower-grade pellets
- Applications: residential and estate boilers, hotels and dormitories, greenhouses, poultry houses, textile and food steam boilers, dryers, hot-air generators
- Standards: CE, EN 15270 (pellet burners), EN 303-5
The NEO MAKİNA Difference
Burner capacity is selected from the boiler's furnace geometry and draught; silo, screw and ash system are engineered for the site. Installation, commissioning, combustion tuning with flue-gas analysis and operator training are included.
Frequently Asked Questions
Which boilers can take a pellet burner?
Steel and cast-iron boilers with sufficient furnace volume, thermal oil heaters and hot-air generators; it replaces the gas or oil burner via a flange adapter.
How much fuel cost does it save?
At current prices, 40–60% versus fuel oil and LPG and 10–30% versus natural gas depending on region; the calculation is provided at proposal stage.
How often is ash cleaning needed?
Every 2–4 weeks with ENplus A1 pellets; longer with automatic ash-removal versions.
