  • Coal fired boiler - Guideline for energy efficient operation

    :Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted., which would otherwise have been wasted.Learn More
