When the boiler trips on fuel starvation more than once a shift.
Likely causes
What to check
Log O2 and CO during a start cycle and inspect the ash depth on the grate.
When to call us
If de-ashing and a fuel change don't clear the smoke — the air control needs recommissioning.
Likely causes
What to check
Track flue gas temperature; a steady climb signals deposit build-up on the exchanger surfaces.
When to call us
Schedule a clean before efficiency loss exceeds the cost of a shutdown.
FAQ
Often yes — sawdust, shavings, shells and offcuts are all viable. We analyse calorific value, moisture and ash content before confirming grate and feed design.
Where the fuel is a by-product of your own process it is usually far cheaper, plus it carries a lower carbon profile. Bought-in chip or pellet needs a proper delivered-cost-per-GJ comparison, which we prepare as part of an assessment.
More frequent de-ashing and fuel handling attention than gas or oil, but comparable to coal. A well-specified maintenance contract keeps availability high.
