Heating and power plants must continuously improve their energy efficiency, and it can be significantly improved by investing in fuel quality and quality control. These are emphasized, in particular, when switching from the combustion of more homogeneous coal to the combustion of inhomogeneous biomass. It is important to determine the exact energy content of the fuel in order to get the right price for the fuel. In addition, information of the moisture content of the fuel is important for optimizing the combustion process and fuel logistics.
Huge quantities of biomass and coal are transported to power plants with tens, sometimes hundreds of trucks and train wagons. Taking samples of the entire load manually is time-consuming, insufficient and unreliable. This causes faults and increases the margin of error in the quality determination. The Q-Robot sampler automatically takes several samples of each incoming truck and train load, changing the point and depth randomly, and always in accordance with solid biofuel sampling standards.
