 Automatic pellet boiler 200 kW FOCUS  with industrial pellet burner 200 kW FOCUS

Solid fuel boiler TM "FOCUS" designed for uncompromising work in combination with a pellet burner TM "FOCUS". The main emphasis in the development and production of the boiler was placed on the efficiency of the heating system, precisely when working with a flare pellet burner on a high-ash (agro) pellet - as the basis for the economic feasibility of purchasing and equipment payback.

Main advantages :

- Maximum ash pan for high ash fuel operation;

- Hybrid structure of the heat-exchange part of the boiler, taking into account the infrared radiation of the burner flame:

- The section for removing the primary thermal stress of the torch (there is no section of the point effect of the torch on the structure of the heat exchanger) - performs in parallel the role of the deposition of heavy particles of the volatile component of the torch;

- The convective part of the heat exchanger is maximally developed in combination with a highly efficient horizontal heat exchanger;

- Thought-out convenient maintenance of the heat exchanger (wide hatch, horizontal cleaning, ash chamber in front of the chimney);

- The ashtray of the high-capacity boiler is designed for operation in an industrial environment. With the correct selection of equipment, even for high-ash pellets;

- Possibility of stable work on wood, as an independent heating device. For a painless transition from pellet heating to wood heating - the boiler is equipped with two doors. One is equipped with a pellet burner, the other door is deaf (for working on wood and briquettes). The transition from one type of fuel to another is carried out by opening one door and closing another (you do not need to snap off, remove, install anything, and the burner automation in the base supports operation in two modes);

- When working on wood, the supply of primary and secondary air is taken into account, the boiler is equipped with appropriate adjustments (both electronic and mechanical). This ensures almost complete combustion of both the fuel itself and the pyrolysis gases that are formed when the wood is heated. Smoke and underburning are minimized;

- The mirror arrangement of the fasteners on the doorways makes it possible to change the side of the door opening without welding. A set of keys is enough for outweighing;

- The boiler is additionally (at the request of the customer) equipped with a ready-made piping of a three-way or four-way valve with IMP Pumps. That, in combination with the control automatics, gives protection against cold return from the heating system and the absence of condensation in the boiler. This, in turn, increases the efficiency by 30% in comparison with a similar boiler without return protection and on a cold system (when the return is below 40 * C). There is no need for the selection of mixing equipment and coordination with the boiler automation;

- For convenience and speed of installation - the boiler is equipped with a Victaulic quick connection system (Victolic connections, they are also Groovlok). For operational work, guaranteed high-quality connection (does not require symmetric tightening as a flange connection, does not require welding at the installation site), allows slight distortions during installation (up to 2-3 *), which gives the installer freedom in case of deviations of the room from the design dimensions. The boiler is supplied with couplings and elbows for welding or threaded connection (specified when ordering).

- The boiler and the system of connections are designed for assembling a boiler house as a cascade, when initially all the power is not required (for example, during the construction of a large facility), and when there is a need to increase the design capacity, several boilers with a total capacity of up to 2.2-2.5 MW are painlessly added. At the same time, the presence of three-way valves on each boiler and a hydraulic arrow in the heating system disconnects the idle boiler from the flow, without limiting the flow of the system and without cooling the coolant through the heat exchanger of the idle boiler.

- Boiler material - structural steel 09G2S. The thickness of the walls of the heat exchange part (firebox and primary heat exchanger, wells) is 6mm. The thickness of the outer shell of the boiler water jacket is 4mm.

- Thermal insulation - 50mm thick basalt mineral wool.

- Boiler casing - brushed stainless steel AISI201

Solid fuel boilers FOCUS- Two doors for a quick transition from the operation of the pellet burner to the wood and vice versa.

- Adjustable hinges and locks for precise adjustment of the tight fit of the door to the opening.

- Ability to change the side of the door opening.

- Hybrid heat exchanger made of plate and fire tube. Where the lamellar course relieves the torch stress and precipitates the bulk of heavy particles, which is especially important when working with high-ash or agro pellets.

- The most developed convective fire-tube part of the heat exchanger actually corresponds to the heat exchange.

- Large door for easy access and complete cleaning of the heat exchanger surfaces.

- Possibility and ease of changing the side of the door opening.

- Large ash pan designed for several days of continuous operation at medium and above average capacities.

 

 

 Pellet burner TM "FOCUS"installed in this kit will work both on clean wood pellets and on agro-pellets with ash content up to 10% (pellets from seeds, corn, buckwheat, rice, furniture, straw).

Burner advantages:

- Automatic ignition (installed Japanese ceramic candles for non-contact air ignition of pellets);

- Movable mono-grate for tedding burning fuel with subsequent pushing of the high-ash residue into the boiler ash pan;

- auger for supplying fuel to the burner combustion chamber;

- Built-in temperature sensor of the burner auger (safety, automation will turn off the fuel supply with an alarm).

- Built-in infrared flame sensor for fixing and monitoring the level of flame radiation (safety, automation records the presence and absence of a flame, using the appropriate behavior algorithms);

- Selected proportions of primary and secondary air for the correct organization of fuel combustion;

- Highly reliable drive of the Swiss company “Belimo” with anti-jamming protection - moves the grate;

- The nozzle of the combustion chamber with air blowing (for models 100-150 kW) performs the functions of cooling the nozzle and simultaneous heating of the secondary air, increases the efficiency of heat generation by the burner, due to the afterburning of gases at the exit from the nozzle;

- On models from 17kW to 300kW, the nozzle is made of stainless alloy;

- All models of flare burners have a "break" in the fuel supply line, ensuring the safety of equipment operation;

Controllerallowing you to easily configure the equipment;

- Internet connection module as an additional option - convenient for remote configuration and control of the burner, creating statistics on fuel consumption, errors, power graph, temperatures, etc.
