Firing

Burning fuel with the AgroTec burner is a very similar process to burning oil. A burner fitted with automatic ash discharge requires little more maintenance than an oil burner. But we do recommend measures such as removing the soot from the boiler.

Fully automatic

The burner and the accompanying feed system operate fully automatically. The burner is controlled by the boilers thermostat.

A preset oxygen function with primary and secondary air supplies ensures the complete combustion of the fuel in a both cost-effective and environmentally friendly manner.

The burner can be adjusted for fuels with different energy and moisture contents.

The burners control unit is pre-programmed so that the on-site engineer can create a basic setting for the fuel that is to be used.

The burner is automatically fed with fuel from the external fuel store by a feed system which is tailored to the boiler and burner and controlled by the burners control unit.

Recommendations on Fuel Pellets

Raw materials

Fuels can be made from different raw materials. The most common material is wood, but there are suitable alternative materials available on the market.

The raw materials have different properties which give them both advantages and disadvantages as a pellet fuel. The important factors are the energy value, the ash content, the volatile matter content, the environmental impact and, last but not least, the price.

You should choose a fuel which has the lowest cost per unit of energy, taking into account the fuel's function in the burner, the ash content and the environmental impact.

The AgroTec burner is primarly designed to be able to burn whole oat kernels.

Oats       Not food grade

Weight 600-650 kg/m

Energy content 4.0 - 4.2 kWh/kg

2.5 ton equivalent to approx.:    10,000 kWh

Moisture content max   12-14%

Ash content / Weight     5-8%

 

Oats are the cheapest way to fuel automatic systems.

Oats are just as good as pellets

This is the burner for you if you want to cut your heating costs right down. With this product the type of fuel you choose depends on your individual circumstances:

Oats are the natural choice if you can use either your own or locally grown fuel.

Why use oats as fuel?

For the financial savings.

Energy can be produced locally and provide employment in the surrounding area.

Unlike firewood, the fuel is always uniform in size and dry, as well as easy to handle, transport and burn in automatic systems. We are preserving open countryside.

Ash and combustion

All systems which burn solid fuel, even automatic systems like the AgroLine 20 burner, require maintenance and servicing.

The majority of the maintenance varies according to the type and quality of the fuel used. This is illustrated by the following comparison: The quantity of ash in oats is approx.: 5-8% by weight, whilst good quality pellets do not contain more than 0.4-0.5% ash by weight.

By choosing a burner and boiler combination including automatic ash discharge, the work is

made much easier.

The ash can easily be returned to the soil, thus reducing the need for fertiliser. Combustion with biofuel does not increase the amount of carbon dioxide (a greenhouse gas) that is released into the atmosphere.

Advice on biofuel  raw materials

For some time pellets made from chips or bark have been a common biofuel, but the market now offers alternative raw materials such as oats. The important factors are energy value, ash content, the volatile matter content, the environmental impact and, last but not least, the price.You should choose a fuel which has the lowest cost per unit of energy, taking into account the fuel's function in the burner, its ash content and environmental impact.

Technical data for AgroLine 20 burner

Feed output, oats            10-20 kW

Combustion efficiency approx.: 90-95%

Voltage                230 VAC

Length from the boiler  450 mm

Height outside the boiler              400 mm

Width outside the boiler               240 mm

Control, regulation and monitoring

The AgroLine 20 burner is controlled by the operation thermostat supplied, normally 75-85C. The control device supplied for the burner then regulates the operation of the burner itself as well as monitoring its functions. The burner's functions comply with the requirements for P-marking.
