Straw boilers are a good solution for medium and small enterprises, small housing estates, single-family houses, schools, kindergartens, and most of all – farms with farm buildings (boiler for drying rooms, greenhouses, etc.) .
In Poland, every year after the cereal harvest, about 25-30 million tonnes of straw remain, of which 10 million tonnes is not applicable. Meanwhile, straw is biomass – an ecological, alternative source of energy used for energy purposes. During straw combustion, the emission of gases to the atmosphere is minimal, and the carbon dioxide balance – zero. After burning the straw, ash remains, containing phosphorus, potassium and calcium compounds, so it can be used as fertilizer.
Low costs of burning with straw up to 100kW – half the cost of burning with coal. The larger the straw-fired boiler – the greater the difference in costs, in favor of straw-fired. If the straw comes from your own farm, the cost is only to harvest the straw from the field.
Thanks to modern design and technological solutions, straw stoves achieve combustion of 80-90%.
