Diary of a Biomass Boiler Engineer:
Rebuild Viessmann 950 brickwork
Rebuild Viessmann 950. Earlier this year we were set the task to rebuild the brickwork of a Viessmann 950kw Pyrotec biomass boiler. No job is too big! Keith, our biomass engineer spent two weeks rebuilding this badly damaged boiler. Here’s his heartfelt diary from that time. Grab a tissue. It gets emotional.
Day 1 – Assessing the Damage. Work Begins
“Today’s challenge, to strip out the damaged brickwork from a Viessmann 950, installed in Mansfield, Nottinghamshire.
The next challenge that we are more than up for is to replace the brickwork and ash trough.”
This biomass boiler was 4 years old, and looking a bit sorry for itself. Keith spent the first day getting stuck in and stripping out the old boiler’s brickwork.
The continuing strip out
“Further issues were highlighted with this boiler:
The block work floor had also succumbed to resin going between the blocks and attacking the insulation underneath.”
Resin had dripped between the block work, and you can see from these photos what a job Keith had ahead of him.
“The de ashing trough has definitely seen better days, with the sides impacting on the de ashing auger, which resulted in much cursing and cutting to free the auger.”
Ash trough finally surrendered
“After some coaxing (and swearing!) the ash trough was removed from the boiler with much elbow grease being used.
Insulation and brickwork to be started in the morning.”
