Emissions From the Combustion of Solid Biofuels

Abstract

Owing to the use of excess straw and unsold grain that has gone bad as a biofuel for heating boilers, farmers may save money to be spent on fuel and it allows them to gain additional profits from the sale of biomass that has not been used. In order to assess the usability of waste biomass as a fuel, tests were conducted related to the emission levels of particulate matter (PM), carbon oxide and nitric oxide that are emitted during combustion in the heating boiler of pellets from pine wood and from rape straw as well as a mixture of pine and rape pellet with lentil grain. The values of the emissions of the agents examined from the combustion of crop-based biomass exceeded by many time the values of emissions that occur as a result of the combustion of pine wood pellet only. The high levels of the emissions of particulate matter, carbon oxide and nitric oxide connected with the combustion of waste crop-based biomass may in the future discredit this material as a fuel for low emission boilers.
