Chenzhou Anren County Changjing Lime Co., Ltd.

Chenzhou Anren County Changjing Lime Co., Ltd. is a lime plant in China with a reported capacity of 144,000 t of lime. It calcines limestone into quicklime in high-temperature kilns. By capacity it ranks #1171 of 1,349 lime plants tracked in China. It emits about 94,819 tonnes of CO₂e per year (Climate TRACE) — roughly the tailpipe emissions of 22,102 cars.

В контексте: как это предприятие сравнивается

На мощности 144,000 t of lime Chenzhou Anren County Changjing Lime Co., Ltd. — это ниже медианная lime plant в China (409,811 t of lime). Подсектор: lime. Как lime plant, оно требует высокотемпературного технологического тепла (обычно 600–900°C) для основных промышленных операций — тепла, которое должно подаваться котлами, печами или прямым сжиганием, и потери через неизолированные сосуды и трубопроводы представляют потраченное впустую топливо. Съёмная модульная теплоизоляция может снизить эти потери на 80–96%, охладив поверхность оборудования до ≤45°C, с окупаемостью часто менее 2 лет. Известковые заводы прокаливают известняк в горячих печах при 800–900°C, и горячую негашёную известь необходимо обрабатывать в изолированных сосудах, чтобы предотвратить реакцию с влагой.

Сравнение производительности и интенсивности CO₂ рассчитано на основе данных промышленных объектов Climate TRACE; роль сектора основана на инженерных справочниках.

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 4,700 MWh/yr (≈ 1,600 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.
