Automatic solid fuel boiler 800 kW: how profitable is it to use

The use of pellet heating in this solid fuel boiler allows saving up to 50% in heating costs compared to traditional energy sources. Even when using expensive wood pellets with an ash content of 1%, fuel costs remain significantly lower. Moreover, the FOCUS 800 kW boiler is ideal for operation with granulated fuel from sunflower husks with an ash content of 5-7%, which makes it universal and adaptable to various types of biomass.

The boiler efficiency when using a pellet burner reaches 92%, which is an excellent indicator for boilers of this type. This is ensured by pyrolysis afterburning of gases arising from thermal decomposition of fuel, and an air supply system that minimizes ash deposition and increases the efficiency of the equipment.

The automatic solid fuel boiler 800 kW FOCUS is also capable of operating on pellets made by handicraft methods, which makes it even more economical for autonomous households. In the basic configuration, the boiler is designed to burn such types of fuel as wood and coal, which expands its possibilities of use.

Features of the boiler include fan-controlled air supply with ecoMAX 260 MINI controller, which regulates the operation of the heating circuit, indirect heating boiler pump and blower fan. The boiler is equipped with a horizontal three-way heat exchanger with an area of 65.8 m², doors for manual fuel loading and the ability to install a pellet burner. The structure is made of durable 09G2S steel, which guarantees the reliability and durability of the equipment.

Among the unique additions in the field of heating equipment, the boiler supports pyrolysis afterburning of fuel from thermal decomposition, fully controlled air supply to the combustion chamber, which also reduces soot deposition on the heat exchanger and combustion chamber walls. The optional torch-type pellet burner has an efficiency of 92%.

Why choose the automatic solid fuel boiler 800 kW FOCUS

FOCUS 800 kW is the optimal solution for boiler houses, providing high heating efficiency with minimal fuel costs and comfortable control in automatic mode.

The automatic solid fuel boiler 800 kW FOCUS can operate on handicraft pellet granules. For these purposes, foliage, wood waste, chopped straw, various agricultural waste and peat can be used. Even with an increase in the ash content of the fuel, the proposed equipment will cope with the heating task, and the costs for the granule can be minimal for you.

In the basic version, the boiler is designed to burn solid fuels such as wood, coal, including DG brand.

Features of solid fuel boiler 800 kW FOCUS 

The proposed automatic solid fuel boiler FOCUS 800 kW when operating on manual fuel loading has a number of distinctive qualities and advantages that have no analogues from other manufacturers:

• controlled air supply to the furnace, controlled ecoMAX 260 MINI controller (included in delivery);
• the built-in microcontroller is connected to the indirect hot water heating boiler pump (switching it off when the set temperature is reached), the boiler heating circuit, the booster fan, together providing the temperature;
• There are 2 inputs for sensors, 1 input for the boiler protection thermostat;
• three-pass horizontal heat exchanger with a maximum area of 65.8 m²;
• the kit includes a door for manual loading of solid fuel. The second door is supplied optionally, it has an opening for installing a FOCUS pellet burner. It is installed on the existing fasteners in the boiler, in a mirrored arrangement. When installing an integrated door, the door for manual loading and the door of the pellet burner open in different directions as needed. The sides of the door opening are interchangeable, can be reconfigured depending on convenience and installation of the boiler;
• Automatic boiler operation mode provides more efficient heating. Solid fuel boiler 800 kW FOCUS is a modern program-controlled equipment with two types of fuel loading;
• the boiler is made of structural steel 09g2s from solid elements, with a minimum set of connections, assembled according to the modular principle;
• The 800 kW FOCUS solid fuel boiler has a heat-insulated door that is not subject to thermal deformation under maximum operating conditions;
• To operate the boiler and install the boiler circuit, a safety group is required (purchased separately).

According to the manufacturer's recommendations, the automatic solid fuel boiler 800 kW FOCUS is installed in a separate room, in the boiler room. If necessary, the manufacturer makes boilers with a lower capacity for FOCUS pellet burners, also offered in a wide range of power ranges.

Boiler complies with GOST32452-2013 (EN 15270:2007). A 12 month warranty is provided.
