Furnace burners for liquid fuel, for pulverized solid fuel or for gas; mechanical stokers, mechanical grates, mechanical ash dischargers and similar appliances

1. Scope and Applicability

This PCR covers factory-gate production of completed furnace burners for liquid fuel, pulverized solid fuel, or gas, together with completed mechanical stokers, mechanical grates, mechanical ash dischargers, and appliances with the same primary firing, fuel-feeding, grate, or ash-removal function. It applies to a declared product model and configuration, including fitted controls, drives, fans, housings, and other components that form part of the delivered appliance.

The PCR excludes complete ovens and furnaces, non-electric bakery ovens, separately supplied spare parts, generic fuel-handling plant that does not perform the covered functions, installation and commissioning at the customer site, use-phase fuel combustion, maintenance, and end-of-life. Manufacturing services on materials owned by another party are a service boundary and are not the reference product of this PCR. The foreground package is cradle-to-factory-gate only when every purchased material, component, energy carrier, and waste treatment crossing that boundary is linked to an appropriate upstream or downstream dataset.

Because products within this category differ materially in fuel, rated thermal input, feed or ash-handling capacity, materials, and control configuration, results per kilogram shall not be used for comparative assertions unless those functional and technical qualifiers are equivalent.

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
dq_product_identity	reference product	Retain model, product subtype, intended fuel or handled material, rated capacity, configuration, and approved specification for every represented product.	specification; nameplate; final acceptance record
dq_product_specificity	bill of materials and manufacturing activity	Use the actual product-specific BOM and company-specific manufacturing activity; averaging across models requires a mass-weighted representative mix and disclosure of every included model.	controlled BOM; production mix; allocation worksheet
dq_temporal	all foreground records	Use one common representative reporting period, normally 12 consecutive months; justify campaign data, shutdowns, abnormal tests, and extrapolation.	dated records; operating calendar; representativeness review
dq_geography_technology	upstream datasets	Match supplier geography, material grade, production technology, electricity supply, fuel state, and waste-treatment route where material; document proxies.	supplier data; dataset metadata; proxy log
dq_completeness	inventory	Reconcile product mass, material issues, energy invoices/meters, test logs, and waste manifests; add every omitted product-specific material, test fuel, finishing chemical, waste, and direct emission as a separate atomic flow.	mass and energy reconciliation; omission register; signed review
dq_emissions	direct emissions	Use monitoring frequency and conditions sufficient to represent included operation, retain factor provenance and abatement status, and do not import upstream emissions into foreground direct-emission rows.	raw monitoring; method; calibration; calculation file; boundary check
dq_uncertainty	calculated and allocated values	Document measurement uncertainty, factor uncertainty, allocation sensitivity, and the effect of unresolved UUIDs and missing empirical ranges.	uncertainty register; sensitivity calculation; review sign-off

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_identity	reference product	Fail validation when product subtype, model/configuration, intended fuel or handled material, rated capacity, product mass convention, manufacturing site, or factory-test route is missing.	un-cpc-3-0-2025
validate_reference_mass	normalization	Require covered_appliance_output to equal exactly 1 kg after normalization and reconcile the denominator to accepted finished-product mass records.	eu-pef-2021-2279
validate_process_routes	conditional processes	Require every applicable onsite surface-treatment and hot-test route to be included; require inapplicable routes to be explicitly declared rather than represented with invented zero values.	ifc-metal-products-ehs-2007
validate_atomic_inventory	inventory rows	Reject combined material, fuel, utility, waste, wastewater-and-residue, or emission-group rows. Require each actual unlisted BOM material, fuel, chemical, waste, and direct emission to be added as one atomic exchange.	eu-pef-2021-2279
validate_balance	material and energy records	Require product-specific BOM reconciliation, electricity reconciliation, test-fuel reconciliation, and documented explanations for material mass-balance gaps.	eu-pef-2021-2279
validate_emission_boundary	direct elementary emissions	Reject upstream electricity, material, fuel-supply, or waste-treatment emissions in foreground direct-emission rows; require source, method, compartment, abatement, and allocation evidence for each direct release.	ifc-metal-products-ehs-2007; eu-pef-2021-2279
validate_unresolved	UUID and range review	Report unresolved UUID rows and unresolved empirical range needs as incomplete review items; do not substitute proxy UUIDs or invented ranges.
