AGRICULTURAL BIOMASS HOT AIR GENERATORS
AGRO 200
PELLETECH AERO CATALOGUE
PelleTech Agro is a safe air generator because it is fitted with Safety Lock System. The system, connected directly to the circuit board, closes the passage between the combustion chamber flame and the containment silo. The PelleTech Agro is particularly suitable for winter heating of work places such as workshops, warehouses, sheds, greenhouses and farm buildings. The Agro air generator guarantees quality, efficiency and safety in compliance with Standards. The air generator uses solid biomass fuels such as: olive pomace, almond, hazelnut shells, sawdust pellets, etc.
The technology of the hot air generator PelleTech Agro 200 provides the highest quality of a high efficiency heat exchanger and allowing the customer to direct savings in operating costs.
The combustion chamber is unique on its kind, it is designed and manufactured from stainless steel and coated cast iron for superior protection from the oxidative substances produced during the combustion of biomass (Pellets, husk etc.) And double tube bundle to achieve maximum heat exchange between the inside and the outside air, while ensuring strength and longevity.
The development of the tube bundle two routes in the horizontal position maximizes the exploitation of all the generated calorific power (produced by flame and the flue gases) prevents the deposition of ash, thus reducing the risk of obstruction and frequency of cleaning.

Shell and tube fumes-air heat exchanger: heat exchanger where the hot fumes are conveyed
Combustion chamber: Bimetallic stainless steel AISI 304 combustion chamber lined with cast iron plates to flame contact points with the walls that ensures very high resistance to chemical processes and temperatures developed in the combustion chamber.
Burner: The body is made of stainless steel and the grid consists of cast iron inserts
Ports for cleaning and inspection: heat exchanger cleaning doors that function as security doors and protection from overheating (lined with refractory material vermiculite)
Exhaust tube which leads the fumes to the chimney
Reinforced steel screw: lengthens the average life span of the fuel feeding system.
Motor reducer: driven by an electric motor, it allows the screw to transport the fuel
Dual feeding motors new generation: High performance with very low energy consumption, covering all the new European directives.
Pellet hopper: the capacity up to 1 m³ allows prolonged operational autonomy
Exhaust gas temperature control system: Electronic exhaust temperature sensor that provides feedback to the boiler control system and result in adjustment to prevailing combustion conditions and flue gas exit at very low values of the order of 180 ° C.
Automated supply system equipped with a safety device which maintains the continuous seal between the stocking device and the fuel line and prevents the back flow in the fuel line and the fuel tank (Back burn Protection Starvalves System, BPS).
Main Combustion air supply blower
Dual centrifugal fans air supply 17.000 m³ / h (for 200.000 kCal) and 28.000 m³ / h (for 350.000 kCal)
BURNER
If the combustion chamber is the heart of the air furnaces PelleTech Aero Agro 200, the burner is its strength.
The burner is made of stainless steel type AISI 304 while the grate combustion of certified high quality cast iron (GG-20), making it as a burner that can handle difficult types of fuel.
The boiler combustion chamber is designed in the shape of disc for economic and productive fuel management and thanks to the digital control panel that provides ease of use and operation for users. Plane grate systems are suitable for fuel with moisture content below 35% MC (wet basis). This is because the fuel is fed directly into the combustion chamber by the fuel feed mechanism, rather than being dried first as in the case of the inclined grate plants. The Agro plane grate can tolerate up to 40% MC fuels. In the underfed type, fuel is fed by auger into the base of an inverted cone or trough, where it wells up into the combustion chamber, spreading out to the sides.
Primary air is supplied below the fuel, and secondary air above. Underfed stoker is supplied as part of a complete plant package; Ash is created on all sides of the combustion zone, and its removal from the combustion bed relies on simple displacement due to the emergence of new fuel in the centre of the combustor. The removal of ash from the bottom of the combustion chamber is by manual intervention, but it is an option to have the ash augured from the bottom of the combustion bed to an external ash bin.
BACK BURN PREVENTION
Safety is not an optional for us. It is for this reason that we have fitted our boilers with an innovative system, connected directly to the circuit board. This closes the passage between the combustion chamber flame and the containment silo, ensuring perfect isolation of the material stored in the hopper. This type of system has the advantage of guaranteeing lower fuel consumption in the minimum phase due to closure of the air passage.
AUTOMATIC MANAGEMENT
electronic heat regulator is enhanced with many functions. It has been integrated with a combustion phase dedicated exclusively to biomass. This has allowed us to implement a control system in the combustion phases on the circuit board, which allows the automatic passage from pellet to biomass fuel. The circuit board controls and manages all generator components. The board establishes the different operating phases by reading the probes, which are:
ignition, maximum power, modulation and standby.
CLEANING AND AUTO CLEANING SYSTEM
Periodic maintenance drastically reduces the probability of problems through time, thus increasing the reliability of the machinery. It is recommended to clean the generator with a handy brush in order to maintain the same level of efficiency. This allows cleaning the shell and tubes quickly. Another optional available is the automatic ash extraction device
BLOWER FOR AUTOMATIC IGNITION
Generator switch-on is manual, but it can be automated by requesting the installation of the blower as an optional. It is an accessory that allows making the most of the potential of the electronic control unit. This device blows air at a very high temperature onto the biomass fuel in the burner, triggering combustion. The front opening permits the cleaning of the combustion chamber in a short time.
PELLET SILO
Positioned on the side of the boiler, they have a truncated inverted pyramid shape. In the standard edition the Silo is offered with a capacity of 1 m³. The hopper is adapted depending on the generator power band. For those machines, which have the smallest size mounted, a larger hopper can be requested.
