Feb 15, 2012 · It may be as simple as cleaning the boiler plate. A lot of back boilers/wrap around boilers become coated with a very heavy slag build up which stops the conduction heat transfer from the coals to the water inside the boiler. This slag will have to be scraped using a good paint scraper and glove, preferably when there is a good hot fire down.

Having worked with coal-fired steam locomotives, I can say that even capably-fired coal leaves build-up. Just like we must clean our fire tubes, the asker needs to clean his chimney. We have the advantage of always tending our fire to ensure good combustion and have a short hot flue. A fireplace or stove lacks both those advantages. Clean your

The water on the other hand will not run hot out of the taps even though i can here it bubbling and have to put the radiators on to disperse some heat.
Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C (Shen and Cheng, 2004).
