Daye Dajing Calcium Industry Co., Ltd.

Daye Dajing Calcium Industry Co., Ltd. is a lime plant in China with a reported capacity of 409,811 t of lime. It calcines limestone into quicklime in high-temperature kilns. By capacity it ranks #724 of 1,349 lime plants tracked in China. It emits about 269,847 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 62,901 cars.

Facility data: Climate TRACE v6 (asset-level capacity & CO₂e, CC BY 4.0), id ct-38468710.

En contexte: comment cette installation se compare

À 409,811 t of lime, Daye Dajing Calcium Industry Co., Ltd. est autour de la médiane des lime plant en China (409,811 t of lime). Sous-secteur: lime. Comme lime plant, elle nécessite une chaleur de procédé intensive (typiquement 600–900°C) pour ses opérations industrielles essentielles — chaleur qui doit être fournie par des chaudières, fours ou combustion directe, et les pertes par les récipients et tuyauteries non isolés représentent du combustible gaspillé. L'isolation modulaire amovible peut réduire ces pertes de 80–96%, refroidissant les surfaces à ≤45°C, avec des délais d'amortissement souvent inférieurs à 2 ans. Les chaufourneries calcinent le calcaire dans des fours chauds à 800–900°C, et la chaux vive chaude doit être manipulée dans des récipients isolés pour prévenir la réaction avec l'humidité.

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 9,000 MWh/yr (≈ 3,100 t CO₂/yr) — scaled to this site's reported CO₂ within its sector. Bare or damaged surfaces recover several times more.

See Inzonex insulation → Estimate your site →

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.

External climate finance your country can access

Domestic energy-efficiency grants are limited here; industrial decarbonisation is mainly funded externally:

• Japan JCM (Joint Crediting Mechanism) — Japan co-finances diffusion of decarbonising tech incl. INDUSTRIAL ENERGY EFFICIENCY in partner countries, in exchange for carbon credits. Channels: MOEJ model projects, ADB trust funds, NEDO demonstrations.
• UK International Climate Finance (ICF / ODA) — ~GBP 6bn ODA over 3 yrs; industrial-decarbonisation flows via Climate Investment Funds (CIF) - Clean Technology Fund.
• Green Climate Fund (GCF) + ADB / World Bank / UNIDO — Concessional finance & grants for industrial energy efficiency. E.g. GCF $200M ADB-led India Green Finance Facility; World Bank FP071 'Scaling Up Energy Efficiency for Industrial Enterprises in Vietnam'; ASEAN ACGF energy-efficiency revolving funds incl. SMEs.

CBAM. Exporters of cement, steel, aluminium, fertiliser, hydrogen and electricity to the EU face the Carbon Border Adjustment Mechanism — cutting embedded emissions (efficiency + insulation) lowers the levy.
