BOILER CONTROL UNIT

As boiler control unit an innovative controller with flexible settings and a large number of functions has been used to meet the needs of demanding, modern users - ecoMAX 260 TOUCH.

The microcontroller unit is designed to control the operation of a boiler with a fan. The unit stabilizes the boiler temperature by smoothly controlling the fan speed and turning off the fan if necessary.

The process of ignition and combustion of fuel in boilers with an injection fan with boiler temperature, boiler overheating and flue gas temperature control is also fully controlled, the unit controls heating circuits and a hot water boiler, protects selected circuits from overheating.

On board it has an output for controlling the blower fan, heating system pumps and hot water treatment system.

Instructions for setting and controlling the unit are provided to the user together with this manual when purchasing the boiler. Be sure to read the manual and instructions on the eve of starting the boiler.

The principle of operation of the pyrolysis boiler FOCUS

Initially, the boiler was designated as a specialized solution for the automated control of solid fuel combustion; the boiler is equipped with gas-tight doors for safe operation in the solid fuel gas generation mode. The control unit has appropriate settings and algorithms to operate in these modes.

Today, working on solid fuel in the gas generation mode is the most complete and efficient way of burning solid fuel.

The principle of operation of the boiler is based on the combustion of solid fuel in the gas generation mode, when only the lower part of the fuel takes part in thermal decomposition. During operation on solid fuel, after its height, the process of pyrolysis decomposition of biomass takes place with the release of pyrolysis (generator) gas, mixing with the corresponding amount of air oxygen in specialized conditions of the nozzle, forming an oxidation reaction with the presence of a flame, accompanied by the release of heat, gets to the heat exchanger and heats the coolant. In conventional fuel combustion devices for full-fledged combustion of pyrolysis gas, the boiler is controlled automatically using the ecoMAX260 TOUCH control unit, which monitors the temperature of the coolant leaving the boiler, and accordingly regulates the addition of air to the furnace.

Flue gases from the combustion chamber, passing through the heat exchanger, leave their thermal energy and go out to the chimney.

To protect the boiler and the heating system from an increase in maximum pressure, as well as to remove air, a protection group must be installed on the boiler (not included in the delivery set).

Economic justification of pyrolysis (gas generator) heating

Today, the quality and quantity of solid fuel for the needs of thermal energy generation is constantly and steadily decreasing. This trend forces the consumer to seek and choose non-standard solutions for heat generation and low-grade fuel combustion. Manufacturers, in turn, are going to improve the methods of fuel combustion. Scientific substantiation of the process of pyrolysis (gas generation) of solid fuel and biomass waste - provides an economic justification and perspective for the next decades of this technology. Having experience in the development and operation of boilers in gas generation mode since 2014, having clarified the nuances and operation on the part of the consumer, personnel, we are ready to offer gas generation of solid fuel and biomass waste, agricultural waste in a reliable product like a pyrolysis (gas generator) boiler FOCUS. This type of equipment already now gives a payback when switching to waste fuel, waste, combustible residues that are inevitable during construction or repair work, in the production of various products (from agricultural topics to printing houses, furniture production, and other activities). This is a significant economic difference in order to consider waste from economic activities as an alternative type of fuel and not save on heat by heating all the necessary premises and open areas.

Considering that in Ukraine there is a large amount of biomass as an inevitable remnant of agricultural activity, gas and fossil fuels are becoming more expensive, the proposed pyrolysis (gas-generating) boiler FOCUS provides a fairly complete processing of biofuel into generator gas with a high combustion temperature (hence the economic effect). The equipment provides pyrolysis (thermal decomposition) and afterburning of combustion products at a temperature of 1300-1600 * C, reducing ash deposition on the heat exchanger and walls, afterburning ballast gases, for which there is not enough temperature in a conventional boiler with traditional layer combustion and the fuel is essentially in the form of smoke - goes into the atmosphere. In the pyrolysis (gas generation) mode, with correct high-temperature combustion, a developed convective heat exchanger, a rare efficiency is achieved in the 92%, economically distinguishing this type of equipment along with more expensive electric and classic boilers.

In addition, the pyrolysis (gas-generating) boiler FOCUS has a special design of the combustion chamber, where combustion goes from top to bottom, essentially bottom combustion, which allows you to add fuel without stopping the boiler for a new bookmark (which in classic boilers smokes and does not burn until it warms up for the whole bookmark volume).

The developed convective part of the heat exchanger is designed to remove a large amount of heat from rapidly moving flue gases from a high-temperature torch, throwing out only the necessary heat into the street to protect the flue from condensation in severe frost, increasing the efficiency of the equipment.

Pyrolysis boiler 50 kW FOCUS on solid fuels can operate on pellets made by home and artisanal methods, lump fuel, gas coals (which practically do not burn in classic boilers), various briquettes, construction fuel waste. In this case, the cost of heating autonomous farms is reduced to a minimum with a level of comfort comparable to gas heating.

Features of the pyrolysis boiler 50 kW FOCUS 

The proposed generator boiler FOCUS has a number of distinctive qualities and advantages that have no analogues in other manufacturers:

• fan air supply, controlled by the ecoMAX 260 sensor controller (included in the delivery set);
• the controller controls the gasification chamber fan, the boiler pump and the DHW heating pump;
• there are 3 temperature sensors (boiler, hot water supply, flue gases), an input for the safety thermostat STB, an input for a room thermostat sensor.
• power supply 220-230 V;
• vertical heat exchanger;
• the boiler is made of steel 09G2S from solid elements assembled according to the modular principle - minimizing welding;
• the doors are thermally insulated and do not undergo thermal deformation at maximum performance;
• security group is not included in the package (purchased separately).

Pyrolysis boiler 50 kW FOCUS is installed in a separate boiler room.

If necessary, the manufacturer manufactures boilers of various capacities according to the standard range, for FOCUS pellet burners.
