Caldaia industriale è una centrale elettrica indispensabile, ampiamente utilizzato nell'industria chimica, fabbricazione della carta, tessile, e industrie alimentari. Come combustibile principale, L’efficienza della combustione del carbone e le prestazioni ambientali possono influenzare direttamente il funzionamento della caldaia. Questo articolo introdurrà i principi scientifici, la fase di combustione del carbone nella caldaia a vapore industriale.
La combustione del carbone è un processo di reazione chimica in cui il carbonio, idrogeno, e altri elementi combustibili nel carbone subiscono reazioni di ossidazione con l'ossigeno, liberando grandi quantità di energia termica. L'energia termica può essere assorbita dall'acqua nella caldaia, produrre vapore o acqua calda, applicando nella produzione industriale o nel riscaldamento.

I tipi di carbone utilizzati in caldaie a vapore industriali sono diversi, includendo principalmente l'antracite, carbone bituminoso, lignite, eccetera. Diversi tipi di carbone hanno diversi poteri calorifici, contenuto di sostanze volatili e contenuto di ceneri, e queste caratteristiche influiscono direttamente sul rendimento della combustione e sulle emissioni inquinanti. Ad esempio, l'antracite ha un alto potere calorifico e una combustione stabile, ma ha un basso contenuto di sostanze volatili ed è difficile da accendere; il carbone bituminoso ha un alto contenuto di sostanze volatili, che facilita l'accensione, ma durante la combustione, tende a produrre fumo nero.
Il processo di combustione del carbone nella caldaia a vapore può essere generalmente suddiviso nei seguenti processi o fasi.

Caldaie industriali a carbone utilizzare diverse tecnologie di combustione per migliorare l'efficienza della combustione e ridurre l'inquinamento.
Qualità del carbone: Il carbone con alto potere calorifico e basso contenuto di ceneri ha un'efficienza maggiore

Durante il processo di combustione del carbone, various pollutants are produced, including:
Optimize the combustion technology: Use efficient coal powder combustion technology or circulating fluidized bed combustion technology.
Improve the coal quality: Use the coal with less ash and high calorific value.
Equipment maintenance: Regularly check and maintenance the combustion equipment.
Install environmental protection equipment: Install efficient desulfurization, denitrification and dust removal equipment.
Coal combustion is an important energy for industrial steam boiler. But the combustion efficiency of coal and the environmental performance of coal should be improved continuously. If we use advanced combustion technology, improve the coal quality and install environmental protection equipment, we can improve the combustion efficiency, reduce pollution, promote the sustainable development of industrial production.
