Fuel handling, boiler tuning, emissions compliance
Commissioning software for biomass and EfW plants where fuel handling and combustion tuning decide whether the plant ever hits availability targets.
Biomass and waste-to-energy plants live or die on fuel handling reliability and combustion tuning, with emissions compliance testing sitting on the critical path to the operating permit. Deskely tracks fuel reception, handling, boiler and flue gas treatment as subsystems in one register, so combustion tuning runs are evidence rather than a log kept by whoever was on shift.

The problem
Fuel handling failures are the reason EfW plants miss availability, not the turbine.
Reception, storage, conveying and feeding systems for a heterogeneous fuel see mechanical failures during commissioning that a clean-fuel plant never would, and every one of them needs to be closed before combustion tuning can proceed reliably.
Combustion tuning itself is iterative — grate speed, air distribution and fuel feed rate adjusted repeatedly against emissions readings — and without a structured record, the tuning history is lost between shifts.
Deskely tracks fuel handling punch and combustion tuning runs against the same subsystem tags, so the plant's readiness for a reliability run reflects both mechanical completion and combustion performance.
Setting up the register
Fuel handling, boiler and flue gas treatment are separate subsystems with separate completion paths.
The plant is broken into fuel reception and storage, conveying and feeding, boiler and grate, flue gas treatment, turbine and generator, and balance of plant — each with its own equipment tags and record set.
P&IDs, mechanical flow diagrams and equipment lists are parsed into a reviewed register, so fuel handling equipment — cranes, shredders, conveyors, feeders — carries the same rigour as the boiler itself.
Prerequisites are mapped between subsystems, so combustion tuning cannot start against a fuel feed system that still has open mechanical punch.
Combustion tuning and emissions
Tuning runs are logged as records, not left in an operator's notebook.
Each combustion tuning run — grate speed, air split, fuel rate, resulting emissions and steam parameters — is captured against the boiler subsystem, building a history that shows what setting produced what result.
Continuous emissions monitoring commissioning and the compliance test campaign are recorded with the same rigour as the readings a permit will require, held against the flue gas treatment subsystem.
Because tuning history is retained rather than overwritten, a later problem can be traced back to the setting that was in place when it started.
First fire to reliability run
First fire, first synchronisation and the reliability run are gated the same way as a gas plant, with fuel handling added.
First fire depends on fuel handling being mechanically complete and loop-checked, ash handling being operational and flue gas treatment being commissioned to the point of safe operation.
Deskely gates first fire, first synchronisation and the reliability run certificates on those prerequisite subsystems, so a fuel handling issue blocks the certificate automatically rather than being discovered during the run.
Reliability run interruptions are logged against the responsible subsystem, which for biomass and EfW plants is disproportionately fuel handling — visible in the data rather than argued about afterwards.
Handover and the permit file
The regulator and the operator both need the same evidence, in different packaging.
The compliance test campaign, combustion tuning history and continuous emissions monitoring commissioning records form the evidence pack the environmental permit depends on.
The operations team receives the same records packaged as an operating dossier — tuning settings, fuel handling punch history, calibration references — so the plant is run from evidence rather than restarted from zero.
Both exports come from the same signed record set, generated on demand rather than assembled twice.
Ash handling and feedstock quality
A biomass or EfW plant fails on the fuel going in and the ash coming out, and both need their own commissioning evidence before combustion tuning can be trusted.
Bottom ash and fly ash handling — conveyors, silos, dosing systems for lime or activated carbon injection, and the vehicles or bins that take residues off site — is commissioned as its own discipline, and a stalled ash conveyor can force an unplanned boiler shutdown just as fast as a fuel feed fault.
Feedstock quality testing — moisture content, calorific value, contamination checks on incoming biomass or waste-derived fuel — is what a permit and an offtake contract both depend on, and disputes over fuel quality are settled by whichever party kept the more complete sampling record.
Deskely tracks ash handling commissioning and residue disposal records alongside fuel reception sampling data in the same register as combustion tuning, so a boiler trip traced back to ash-side equipment or an out-of-spec fuel delivery is provable against dated evidence rather than argued from memory.
What the environmental permit review reads
The fuel handling and emissions records that decide whether a biomass or EfW plant can take waste on a permit.
A biomass or waste-to-energy plant is licensed on continuous emissions performance as much as mechanical readiness, and the fuel it burns is far less consistent than gas. The dossier holds boiler chemistry, emissions monitoring and fuel handling records so the environmental regulator and the offtake counterparty see the same evidence base.

How it runs
From fuel reception commissioning to a permitted, reliable plant.
Biomass and EfW projects reward tracking fuel handling with the same rigour as the boiler, because that is where availability is actually won or lost.
