W kontekście: jak ta instalacja się porównuje

Przy 401,965 t of lime, Calcidrata - Indústrias De Cal, S. A. (Ci) jest poniżej medianę lime plant w Portugal (702,065 t of lime). Podsektor: lime. Jako lime plant, wymaga intensywnego ciepła procesowego (typowo 600–900°C) do swoich głównych operacji przemysłowych — ciepła, które musi być dostarczane przez kotły, piece lub spalanie bezpośrednie, a straty przez nieisolowane zbiorniki i rury stanowią zmarnowane paliwo. Modułowa izolacja demontowalna może zmniejszyć te straty o 80–96%, chłodząc powierzchnie do ≤45°C, z zwrotem inwestycji często poniżej 2 lat. Huty wapienne kalcynują wapień w gorących piecach w temperaturze 800–900°C, a gorący wapień żywy musi być obsługiwany w izolowanych zbiornikach, aby uniknąć reaktywności z wilgocią.

Heat loss & insulation profile

A lime plant like this runs hot equipment that sheds heat continuously: kiln, preheater, hot-gas ducting, valves & dampers (surface/process temperatures around 200–900 °C). These surfaces lose energy to the air year-round; removable modular insulation cuts that loss, brings outer surfaces to ≤45 °C, and unclips for inspection.

calcination-heavy like cement; fuel side only.

Indicative recoverable energy

On an already-insulated site (pipes & valves in cladding / jackets), closing the remaining gaps, flanges and damaged sections and switching to removable covers indicatively recovers about 8,900 MWh/yr (≈ 3,000 t CO₂/yr) — scaled to this site's reported CO₂ within its sector. Bare or damaged surfaces recover several times more.

Indicative, not a measurement. Conservative floor for an already-insulated plant; a TIPCHECK on-site audit gives a measured figure. Industry context: EiiF TIPCHECK — industrial insulation can save ~14 Mtoe/yr in EU, payback typically <2 years.

Safety & the no-regret first step

Bare hot surfaces here exceed the touch-safe limit (EN ISO 13732-1); insulation to ≤45 °C is a worker-safety and compliance win. And before electrification, fuel-switching or CCS, eliminating surface heat loss is the cheapest, fastest, lowest-risk step — audit the bare spots first, rip-and-replace later.

EU: funding & obligation

Obligation. Under the EU Energy Efficiency Directive (Art. 8), large undertakings (>250 staff or >€50M turnover / >€43M balance) must run an energy audit every 4 years or operate a certified energy management system (ISO 50001).

Funding. National energy-efficiency grants and white-certificate schemes typically apply — check the local programme.
