Combined boiler BURNiT Advance UB – A

Universal boiler for heating medium and large rooms.

Thanks to the universal retort burner, different types of fuels can be used:
– Main fuels – agropellets (straw and sunflower)
– Alternative fuels – dry stones from cherries, plums, apricots, peaches and olives.

Constructed according to standard EN 303-5.

The set includes: Combination boiler, universal retort burner and fuel hopper.

 

Advantages

Safety valve 3 bar

Fuel bunker

 

Built-in controller

 

STB thermostat

 

Backfire prevention sensor

Advantages:

  • Built-in controller. Functions: Automatic control of the combustion process. Control of a pump for a heating system. DHW pump control.

  • Universal retort burner. Characteristics: Ability to burn different types of fuels (wood pellets, coal and agro pellets);

  • Two cast iron grills for coal and pellets; Strong cast iron body of the burner; Long service life; Easy maintenance.

  • The combustion chamber of the boiler has a large heat exchange surface and low chamber resistance.

  • Turbulators in the ribbed combustion chamber ensure longer retention of flue gases in the boiler and increase efficiency. Three-way path of flue gases.

  • The water jacket completely surrounds the combustion chamber for maximum utilization of the released heat.

  • Fuel bunker. The hopper is mounted on the side of the boiler. Adjustable support. Convenient fuel filler cap.

Note: When using alternative fuels – sunflower pellets, straw pellets, other agro pellets, various types of stones and nuts, it is possible to deteriorate the boiler’s performance indicators, as well as reduce the time period for cleaning the boiler. This is caused by the fact that this type of fuel does not fall under any certification norm, which does not guarantee the quality of the fuel.

Power, kW:

  • 27, 35, 60, 90

Safety features

  • The controller monitors and regulates the temperature in the boiler.

  • Safety valve 3 bar.

  • Safety heat exchanger connected to the water supply installation. In case of overheating, cold water flows through it, which lowers the temperature in the boiler.

  • STB thermostat stops fuel supply to the burner in case of exceeding the normal temperature regime in the boiler.

  • Backfire prevention sensor.

  • Fuse 6,3 А.

Boiler elements UB:

1 – Combined boiler
2 – Bunker
3 – Safety heat exchanger
4 – Turbolators
5 – Three-way path of flue gases
6 – Ceramic plate to improve the combustion process
7 – Universal retort burner
8 – Cast iron grill for burning coal
9 – Cast iron grill for burning wood pellets, agricultural pellets

Options:

a – Water tank
b – Soft connection for water
c – Safety valve by temperature

Optional:

Temperature safety valve (c) connected to the water tank (a) by a soft connection (b). This prevents self-ignition of the fuel in the bunker, as a result of backfire.
