Boiler Efficiency Improvement amp; Heat Loss Explained

Complete combustion of fuel so that no unburnt is left behind is a good practice and will add to the boiler efficiency. Unburnt carbon coming out of the furnace can be re-injected again into the furnace so that complete combustion of fuel can take place. Bottom ash from the boiler is generally at a high temperature and has a lot of sensible heat.
