Condensing boiler - Wikipedia

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. This condensed vapour leaves the system in liquid Principles of work· Usage· Efficiency· Control· ReliabilityRefuse-Fired Boiler Heat Balance - The Fu Foundation School of · PDF Refuse-Fired Boiler Heat Balance John S.

Condensing boiler applications in the process industry -

Latent heat recovery is the most significant advantage of condensing boilers, greatly improving thermal efficiency. Fig. 1 shows this for a wood chip boiler with a condensing heat exchanger at different excess air ratios (λ). The fuel (wood chips) used in the boiler has Cited by: 113Publish Year: 2012Author: Qun Chen, Karen Finney, Hanning Li, Xiaohui Zhang, Jue Zhou, Vida Sharifi, Jim SwithenbankEPSRC THERMAL MANAGEMENT OF INDUSTRIAL PROCESSESresearch.ncl.ac.uk/pro-tem/components/pdfs/EPSRC_Thermal· PDF I Executive Summary A considerable amount of waste heat in boiler flue gases is in the form of latent heat of water vapour. This energy cannot be recovered until the flue gases are cooled to a temperature below the dew point. One of the main reasons why not
