InterFire automatic central heating boiler

InterFire boiler has been designed as compact structure. Most of the boiler pieces are hidden behind the covers which protects them against elements and mechanical damage. There two main elements within the InterFire box: the boiler's body and the fuel supply system. The body includes: a collector. a steel heat exchange, the combustion chamber and the ash tray chamber. Inside the steel heat exchange you will find vertical hot gas pipes and the deflector. The exchange features a manual cleaning system. The heat exchange is covered by a collector which collects the exhaust and directs it to the exhaust collar.

The exchange rests on the lower part of the body which consist of the combustion chamber and the ash tray chamber, A burner inside the combustion chamber supports a catalyser made of a stainless steel tube. The burner is also fit with an automatic clearing system. Fuel falls down from the auger feeder having its outlet placed above Burner's ash falls from the combustion chamber to the ash tray in the chamber underneath.
The other main system of the InterFire boiler supplies fuel. It is integrated in the external box of the boiler covers. These includes: pressurised air fuel transport and the auger feeder with a motoreducer. Fuel falls from the main fuel container to the auger feeder. This in turn, pushes fuel to the burner in the combustion chamber.

The system of the pneumatic fuel transport system has been located in top of the fuel container and it feeds the container keeping it full. The boiler body connects to the fuel supply system with the collar of the auger feeder.

Two covering panels are fixed in front of the boiler. You can access the combustion chamber and the ash try chamber with the pair of inspection doors under the bottom panel. Under the right panel you can find a revision opening to the bottom part of the fuel supply system. Also, the manuals of the boiler and the controller are kept there/ A control display showing current status of the boiler is fixed at the front wall of the fuel container.

The inlet and outlet of the heating system water are located at the back wall of the boiler. These are threaded pipe ends with a 1 " internal thread. The back wall also holds the exhaust collar connecting the boiler to the flue system. Returning air fan is fixed to the back wall of the boiler over the chimney flue connector. Exhaust temperature sensor and the lambda sensor are fixed at both sides of the fan, The returning air fan is fixed to the tube over the fuel container which delivers air right to the combustion chamber. Amount of air flown by the fan is controlled by the system controller.

The external covers and the body are insulated with mineral wool to reduce heat loss in operation. The covers are made of steel sheets covered with high quality powder paint.
