Environmental assessment of domestic boilers: A comparison

Jan 20, 2017· A life cycle assessment of two different domestic natural gas boilers has been carried out. The assessment used the CML and CED methods, by considering the EPD certification systems categories. The condensing boiler technology has a lower environmental impact than the traditional one in all the impact categories.

Super heater and re-heater coil failures occur very often and thus the boiler have to be shut down affecting power generation. Pre-assessment of the component helps to plan procurement and replacement activities in advance and also improves the reliability and availability of the plant by reducing unplanned forced outages.:International journal of applied engineering research · 2015:P Raghuram · S Hemanath · S H Hiran · M Vignesh · S RanjithBoiler life extension requires accurate condition assessmenthttps://Boiler life extension requires accurate condition assessment. The typical cost for a tube bundle survey and life estimation, approximately $15,000 to $25,000 according to Paterson, is easily recovered if using the results prevents even a single boiler tube failure and subsequent forced outage.
