EMB universal burners — heating oil and rapeseed oil.
Burners from Germany for boilers and warm-air heaters that fire light heating oil and rapeseed oil. Outputs from 27 to 260 kW. We select, install, commission and service them.
A standard oil burner needs a thin, clean fuel. The EMB universal burner has its own heated tank and atomises the oil with compressed air, so it copes with oils thicker than heating oil — above all rapeseed oil.
How the EMB burner works
- Oil is pumped from the supply tank into a tank inside the burner. A float switch keeps the level, and a separate switch stops the burner if the tank overfills.
- A heating cartridge (1100 W) warms the oil to the set temperature — up to 140 °C for rapeseed oil, no preheating for heating oil. Only then does the burner start.
- The nozzle atomises the oil with compressed air, which also serves as primary air. Nozzles of this type wear very little.
- The fan adds secondary air at the baffle plate. The burner control monitors the flame, and the burner shuts itself off if the oil exceeds 150 °C.
Models and outputs
The output range depends on the fuel: on rapeseed oil the same burner delivers less than on heating oil.
| Model | Heating oil | Rapeseed oil | Compressed air | Weight |
|---|---|---|---|---|
| EMB 20 | 33–52 kW | 27–40 kW | 4 m³/h | 20 kg |
| EMB 50 | 50–75 kW | 40–52 kW | 8 m³/h | 25 kg |
| EMB 70/100 | 70–132 kW | 65–101 kW | 11,5 m³/h | 24 kg |
| EMB 150 / 200 / 260 | 148–260 kW | 95–190 kW | 25 m³/h | 26 kg |
Fuels
EMB burners are certified to EN 267 for light heating oil and rapeseed oil. The manufacturer rules out flammable liquids: thinners, petrol, alcohol, brake fluid and antifreeze mixtures. Oil containing water or sludge causes faults, so the tank has to be drained regularly.
What the installation needs
- Compressed air — a compressor sized to the model (4 to 25 m³/h) with an operating pressure of about 0.4–1.5 bar at the burner.
- Fuel supply — a tank and an oil feed system; for rapeseed oil in a cold room, a heated one.
- A flue sized to the output of the boiler or heater.
- A suitable room without high humidity, dust or corrosive vapours, as the manufacturer requires.
- A 230 V supply — the burner uses a 7-pin plug, like a typical oil burner.
Operation and service
A burner running on rapeseed oil needs more attention than one on heating oil. The manufacturer recommends:
- after any standstill longer than 3 days — draining water and sludge from the burner tank,
- every month — cleaning the filters, photocell, electrodes and baffle plate, and blowing out the nozzle,
- once a year — a full service including the heating cartridge and tanks, ideally before the heating season.
We carry out commissioning, combustion adjustment (O₂ 4–5%, Bacharach smoke number below 1) and annual services ourselves, and show the monthly routine at commissioning.
Frequently asked questions
Which fuels can the EMB burner use?
Light heating oil and rapeseed oil — the burners are certified to EN 267 for these two fuels. Changing fuel means changing the settings: preheating temperature, primary air pressure and secondary air.
Do I need a compressor?
Yes. The burner atomises the oil with compressed air. The compressor output depends on the model: from 4 m³/h for the EMB 20 to 25 m³/h for the EMB 150–260.
Will the EMB burner fit my boiler or heater?
Usually yes — it mounts on a flange like a typical forced-draught burner. We check the output, the combustion chamber and the flue. A photo of the boiler or heater rating plate is enough to start.
Send a photo of the rating plate — we will tell you what can be done.
