A torque support for a transport device for fuels of a biomass heating system, including: a base plate having three legs and three sides; and a torque support, wherein the torque support is a 3-point torque support that comprises three fastening points for connecting the base plate to a support structure.

The present invention provides a method and apparatus for controlled burning of experimental solid fuel test strands. The fuel test strand is advanced by a screw attached to a computer-controlled stepper motor. The stepper motor controls the fuel test strand position via a proportional-integral-derivative (PID) control loop, adjusting velocity based on transmission of a diode laser beam located at the desired fuel surface position. This provides real-time monitoring of fuel strand position and fuel regression rate during combustion experiments.
