PZ100RL Biotech Pellet Boiler Maintenance Shipley

BD18 3AN

Description of work:

Biotech PZ 65RI/PZ100RL 99.9 kW pellet boiler troubleshooting. The boiler hadn’t been operating for about 3 months.
System filling – there wasn’t any pressure in the water system.
Fire chamber cleaning . It was not only dirty, but completely full of ash and pellet powder.
Pellet auger cleaning – the auger was comletely blocked, so all the pellet from the dailly container had to be removed and the auger had to be pulled out.

Other maintenance work to do in the near future:

  • Cleaning the heat exchanger
  • Empty the ash containers
  • Replacing the carbons of the igniter and the vacuum fans
  • Replacing the faulty fluegas, outside temperature and burning chamber sensors
  • Put back the ash auger motor
  • Inflate the pressure vessel to 0.75 bar on the air side
  • Reseting pellet suction turbine failure
