 pellet burner

Burner features:

  • Possibility of installation on most boilers for solid fuel or oil
  • The combustion chamber is air-cooled sothere is no need to install the burner deep into the boiler.
  • The burner is protected by mechanical and electrical safeguards.
  • It is possible to burn the firewood without removing the pellet burner.
  • Automatic cleaning of the combustion chamber (high pressure blower and grid)
  • Low power consumption.
  • A grid for even more efficient combustion (without residual ash and slag).

SafetyBurner has several safeguards that provide security (electrical and mechanical):

  • A heat sensor on a dosing pipe. (In case this this pipe is heated over than 80°C / 176°F, the dosing of pellets will stop but the vent will still blow on until the temperature is reduced).
  • A heat sensor inside the burner. (In the event of overheating, the feeding of the pellets will stop).
  • A central heating sensor in furnace
  • A water boiler heat sensor in furnace
  • A fire sensor in the combustion tube (more successful ignitions with no back smoke explosions).
  • Airflow slots on funnel (airflow prevents reverse fire).
  • A soft PVC tube (a feeder & dosing pipe connection). (In case of fire, this pipe will melt down so pellets will no longer fall in the combustion tube)
  • All interior parts must be made of fire-resistant stainless steel.

Burner operation/stages processes

The entire burning operation is run by the microprocessor controller (you will find more info about where to buy and how to instal it in the document). Combustion processes are described in the following sections:

  • Dosage of pellets for the first ignition:

A feeder, which is designed to transport pellets from the reservoir to the combustion chamber, ensures that ideal quantity of the pellets, which accumulating in the chamber for a successful ignition.

  • Ignition of pellets:

When the first dosing process is completed, the igniter turns on and produces hot air to a temperature of 800 - 1000 ° C. With the help of a fan, the first pellets ignite causing a fire.

  • Transition from ignition to full power operation process:

A photocell detects and measures the luminosity of fire, and arranges the increase in fire strength in the  shortest time possible. This is achieved by the speed of the fan and feeder.

  • Operation in full power:

The burner now works with the full power, which has been set in the controller, in order to quickly achieve the right water temperature in the boiler, (also set in the controller). The speed of achieving the temperature depends on the strength that has been entered into the controller.

  • Transition to a maintenance temperature:

When the water in the boiler reaches the set temperature, the controller switches the burner to a maintenance mode. In this mode, the fire strength decreases by more than half, just enough to ensure that the water temperature is only slowly dropping down.

  • The Repeat process:

When the temperature drops at a difference set in the controller, this will switch the burner back to full power operation. The processes of full operation and maintenance are continuously repeated.
