FOCUS

Любое горение топлива представляет собой процесс возгорания пиролизных газов, выделяемых при сгорании дров, угля, пеллет и любого другого углеродного сырья. Конструкция твердотопливного котла FOCUS спроектирована таким образом, чтобы получить завершенный процесс горения с максимальным выделением тепла и аккумулировать его, передав энергию теплоносителю с помощью развитого конвективного теплообменника.

Combustion chamber design

Твердотопливный котел FOCUS спроектирован с учетом эксплуатации pellet burner, для установки которой в отопительное оборудование ФОКУС имеется дверной адаптер. Конструкция топки предполагает наличие двух дверей, что подразумевает его использование как классического твердотопливного дровяного котла, с возможностью работы на дровах, брикетах, угле и пеллетах.

Таким образом, камера сгорания котла ФОКУС адаптирована под сжигание дров (любого твердого топлива) и пеллет. Процесс горения и автоматическая подача топлива при эксплуатации пеллетной горелки контролируется микроконтроллером PLUM, позволяющим подключить до 10 датчиков. При установке пеллетной горелки в твердотопливный котел FOCUS and supply of pellets from the pellet hopper, the buyer receives a pellet boiler room at a lower price with the efficiency of heating equipment 95%.

Heat exchanger

The main combustion product is "bulk" hot air. In addition to efficient combustion of fuel, the boiler must provide heat convection of a large volume of hot air. For these purposes, the heating equipment is equipped with a developed heat exchanger built into the structure of the furnace.

Many solid fuel boilers use cast iron heat exchangers. Heating the metal with a high heat capacity improves the efficiency. Steel heat exchangers also provide good convection, especially in cases of special design solutions.

The FOCUS solid fuel boiler has a combined heat exchanger. Originally a plate type, also used as an ash filter. The main convection of hot air is provided by a horizontal fire-tube heat exchanger, as the most efficient and often used in industrial and pellet boilers.

The design of the heat exchanger assumes that the movement of gases from the burners is fast enough for efficient heat exchange.

Ash cleaning

The possibility of using fuels with high ash content and cleaning the boiler is ensured by its design. A plate heat exchanger is used to sediment the bulk of the ash, which can be easily removed. Serial version of solid fuel boilers FOCUS focused on operation with an ash pellet. The heating equipment is equipped with a fire-tube heat exchange circuit without turbulators (*), which are quickly brought in by ash during the active movement of flue gases from the flare burners and complicate subsequent operation.

Afterburning of pyrolysis gases

Full combustion of pyrolysis gases released during heating of solid fuel reduces the volume of ash emitted and the level of contamination of heating equipment during operation. For the combustion of high-ash fuel, as well as problematic grades of coal (DG grade) and biogranules of lignin with an ash content of 15-17% in FOCUS solid fuel boilers, a classical approach is applied. The air supplied to the combustion chamber is divided into primary and secondary. Primary air is fed under the grate to ensure fuel smoldering. Secondary is supplied above the fuel for afterburning pyrolysis gases and maximizing smoke reduction (underburning of gases).

Automation 

The ecoMAX860P TOUCH sensor automation regulates the air supply to the pellet burner and the solid fuel boiler separately, taking into account the different operating modes of the equipment. This approach implies a wide range of automatic settings.

(*) To all solid fuel boilers FOCUS design changes can be made during production according to the customer's specifications... Can also be installed turbulators provided that wood pellets are used during operation.

Features of solid fuel boilers FOCUS

Solid fuel boilers FOCUS - Firebox - Solid fuel pellet boilers, pellet burners, industrial

The body of the FOCUS solid fuel boiler is made of 092GS carbon steel, which is resistant to corrosion and has increased strength compared to general-purpose steel. Boiler steel grades are not produced in Ukraine, but the design of the boiler implies a balanced thermal load. 

The boiler body is made of 4 mm steel, the inner lining is 6 mm, and is reinforced.

The doors of the combustion chamber, ash pan and heat exchanger are thermally insulated and do not pose a danger to workers in the process of fuel combustion in the furnace. As a result of a well-thought-out engineering solution, the thermal loads of the boiler are within a safe range. On the outside, the doors are coated with gray heat-resistant powder paint.

In the production of a solid fuel boiler FOCUS the technology of weldless assembly is used. With the maximum number of cut and bent elements. It includes the use of adapters such as Victaulic for non-welded connection of pipes for the layout of multifunctional boiler houses with a capacity
up to 2.2 MW.

The boilers are undergoing production testing. If the operating characteristics of the boiler go beyond the normal range, its operation, the 4-way valve and the heating circuit, compensating for the critical parameters, is controlled by the automation.

A fast assembly system is used.

FOCUS solid fuel boilers are pellet automatic boilers with weather-dependent automationconnected to the "Smart Home" system, which do not require a buffer capacity. With their help, autonomous heating of objects remote from public mains is provided, using biogranules in full automatic mode. 

Our engineering company is engaged in the deployment of FOCUS autonomous boiler houses with a capacity of 17 kW to 2.2 MW.

For remote objects

Remote objects, such as gas stations or houses outside settlements, can use automatic heating units for autonomous heating and heat production without gas with a comparable level of comfort.

Using FOCUS heating equipment, from ordinary solid fuel boilers for heating private houses, shops, offices and industries, you can get boiler rooms that work with manual loading (emergency) and use of firewood on the principle of gas generating boilers and provide automatic fuel supply (with the help of additional equipment).

FOCUS solid fuel boilers in combination with a flare burner and a hopper work as pellet boilers adapted to the combustion of agricultural granules. During the combustion process, the equipment is contaminated with ash in a controlled manner due to the well-thought-out technology of burning pellets, which is also used when laying firewood, coal or briquettes, and the emitted pyrolysis gases. Flue gases provide a high coolant temperature and good heat transfer.

With all the advantages, this equipment has a not very high price and high efficiency with the ability to operate on an agricultural pellet in a fully automatic mode.
