Burning agrobiomass in practice? Is it worth it?

 Prices of pellets and gas reach the highest levels due to energy crisis. It is not surprising that many customers are looking for a cheap alternatives or renewables to burn in their furnace or burner. Not only the price level prompts us to look for alternative fuels, but also the very availability of gas or pellets - in many parts of the country they are simply difficult to obtain.

Due to voices in the Internet and in the opinion of many users, it is worth considering agro biomass burning. Is it worth it?

 Agro biomass is cheaper but more difficult to burn then pellet or woodchips.  It should be remembered that cheaper agro fuels have more ash and lower caloric value. This gives less energy than certified forestry biomass and a greater combustion loss - we have more ash. Therefore, to achieve similar combustion parameters, we need to add a little more fuel over time - only if the burner does not burn it, we can clog it with slag and ash, and as a result, even damage it.

Oat boilers and burners - what to recommend?

Oats are a very interesting alternative to pellets - it is a renewable fuel, we have oats every year and much cheaper than sawdust pellets. Unfortunately, it is a highly coking fuel, requiring different combustion temperatures and therefore quite difficult to burn. Some burner designs without mechanical cleaning are completely unsuitable for burning or co-firing oats. Only burners with mechanical deslagging and good aeration can cope with oats, but here we will still have a lot of ash, i.e. loss of combustion efficiency. To reduce them, it is better to mix oats with pellets or wood chips in order to achieve optimal combustion parameters. In our MOC or Brenner burners as well as in the Biowarmer boilers, agrobiomass can be burned due to the staggered structure of the burner, thanks to which it is effectively cleaned on any fuel.

Burners and boilers what about a feeder for burning straw briquettes - what to choose?

Straw briquette is another cheaper alternative to coal or pellets. It is another renewable biofuel - its resources are renewed every year, so it gives us 100% energy independence, and the low price of straw briquetting guarantees cheap heating. Straw briquettes have a lower calorific value and more ash than sawdust, but they are much cheaper. They can be automatically burned in our automatic biomass combustion sets and in the Biowarmer series boilers. For years, we have had experience in this field in cooperation with technical universities.

Pellets and oats? Is it worth it?

 As we wrote earlier, there are practically no burners that can convert pellets into oats by 100%. And if there are, for example, our automatic biomass combustion sets, their price is much more expensive and in the case of home stoves it will not pay off quickly enough. Therefore, it is much better to decide to co-burn grain and pellets in the burner, keeping the right proportions. The very idea of ​​co-firing in many devices gives a safe proportion of 20% to 80%, but you can try to adjust the right mixture yourself. Boiler for the combustion of agrobiomass and biofuels - construction The burner and boiler for the combustion of agro biomass and biofuels must therefore be dedicated, specially built for burning with more difficult fuel. The furnace itself must be larger than for pellets due to the volume of agrobiomass, density and calorific value. The feeders must also be proportionally larger and stronger. The burner itself must be more efficiently ventilated and have efficient mechanical cleaning and deslagging of its entire surface.

Therefore, the constructions of such boilers are more expensive than pellets because they have industrial solutions. It should be remembered that in accordance with the current regulations, we should always burn the fuel for which it was certified in the boiler. The user does the co-firing of biomass fuels at his own risk as part of a combustion trial or a home experiment. Combustion of agrobiomass may require the reduction of NOx emissions, and specialized installations are very expensive and do not make economic sense for domestic use.
