One of the largest accredited chimney testing centers

Biomass Boiler testing

Accredited type testing of biomass boilers for solid fuels, manually and automatically stoked, nominal heat output of up to 500 kW according to EN 303-5 standards.



Possible test sequence for an automatically stoked, biomass boiler:

  • Pressure test water side
  • Leakage of the combustion system
  • Electrical power consumption
  • Water side resistance
  • Surface temperatures
  • Sudden absence of heat dissipation
  • Loss of electrical power supply
  • Test for unstable combustion chamber pressure
  • Test of ignition failure during start up
  • Test of fuel line safety shutdown device functionality
  • Test for blocked fuel line
  • Loss of combustion air supply
  • Efficiency and emissions during nominal heat output
  • Efficiency and emissions during minimum heat output
  • Construction and safety requirements
  • Dimensions and tolerances
