Automated pellet boiler 40 kW FOCUS with built-in industrial pellet burner, built-in auger ash removal system with a sliding ash collection container
The FOCUS automated pellet boiler is designed for uncompromising operation as a single unit. The main emphasis during the development and production of the boiler was placed on the efficiency of heat removal specifically when working with a flare pellet burner on high-ash (agro) pellets. First of all, based on the economic feasibility of purchasing and the payback of equipment while reducing manual labor to clean the boiler from ash and deposits due to the installed screw ash removal system, which makes it possible to increase the periods between cleanings and remove ash into a rolling container.
Main advantages :
— Maximum ashpit for operation on high-ash fuel;
— Built-in system for auger ash removal from the boiler ash pan;
— Built-in sliding container for collecting and removing ash;
— Built-in system of auger ash removal from the burner grate space into the boiler ash pan;
— The pellet burner is cleaned into the ash pan of the boiler, and through the screw ash removal system into an external container;
– Hybrid structure of the heat exchange part of the boiler, taking into account the infrared radiation of the burner flame:
— The area for removing the primary thermal stress of the torch (there is no area for the point effect of the torch on the heat exchanger structure) – it simultaneously plays the role of settling heavy particles of the volatile component of the torch, working as an ash filter;
— The convective part of the heat exchanger is maximally developed in combination with a highly efficient horizontal heat exchanger;
- Thoughtful convenient maintenance of the heat exchanger (wide hatch, horizontal cleaning, ash chamber in front of the chimney);
— The ash pan of the high-capacity boiler is designed to work in industrial conditions. With the right selection of equipment, even on high-ash pellets;
— Location of the pellet burner on the boiler door in a suspended version, reinforced door hinges;
– 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 pumps. Which, in combination with control automation, provides protection against cold return from the heating system and the absence of condensation in the boiler. This, in turn, on the 30% increases the efficiency 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 to select mixing equipment and coordinate with boiler automation;
- For ease and speed of installation - the boiler is equipped with a Victaulic quick connection system (Victaulic connections, they are Gruvlok). For operational work, guaranteed high-quality connection (does not require symmetrical tightening as a flange connection, no welding work is required at the installation site), allows for slight distortions during installation (up to 2-3 *), which gives freedom to the installer in case of deviations of the room from the design dimensions. Complete with a copper there are couplings and branches under welding or carving connection (it is specified at the order).
- The boiler and the connection system are designed for assembling a boiler house according to the cascade type, when all the power is not initially 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 switch in the heating system disconnects the idle boiler from the flow without restricting 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 (furnace and primary heat exchanger, shells) is 6 mm. The thickness of the outer shell of the water jacket of the boiler is 4 mm.
- Thermal insulation - basalt mineral wool 50mm thick.
– Boiler casing – polished stainless steel AISI201
— Adjustable hinges and locks for fine-tuning the tight fit of the ash pit door and heat exchanger to the opening.
- Possibility to change the opening side of the doors.
— Removable sliding container for the boiler auger ash removal system.
— Automatic cleaning of the burner into the general ash removal system of the boiler;
- Hybrid plate and fire tube heat exchanger. Where the lamellar stroke relieves the stress of the torch 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 really corresponds to heat exchange.
— Large door for easy access and complete cleaning of the heat exchanger surfaces.
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).
The built-in pellet burner TM "FOCUS", included in this set of equipment, will work both on clean wood pellets and on agricultural pellets with an ash content of up to 10%. In this case, fuel pellets from sunflower waste, corn, buckwheat, rice, furniture waste and straw can be used without restrictions.
Pellet boiler FOCUS 40 is the optimal solution for households and small shops, as well as remote sites.
Advantages of the built-in burner:
- automatic ignition (installed Japanese ceramic candles for contactless air ignition of pellets);
- movable mono-grate. It is used for tedding burning fuel, followed by pushing the high-ash residue into the boiler ash pan;
- auger for supplying fuel to the combustion chamber of the burner;
- built-in temperature sensor of the burner auger (safety, automation will turn off the fuel supply with the transmission of an alarm signal);
- 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 appropriate behavioral scenarios);
- 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 combustion chamber nozzle with air purging (only for 120-150 kW models) performs the functions of cooling the nozzle and simultaneously heating the secondary air. Increases the efficiency of heat production by the burner due to the afterburning of gases at the exit of the nozzle;
- on models from 17 kW to 150 kW the nozzle is made of chromium alloy.
All models of flare burners have a "break" in the fuel supply line, ensuring the safe operation of the equipment. Using the controller, you can easily customize the operation of the equipment.
