When shopping for high-efficiency furnaces and boilers, look for the ENERGY STAR® label. If you live in a cold climate, it usually makes sense to invest in the highest-efficiency system. In milder climates with lower annual heating costs, the extra investment required to go from 80% to 90% to 95% efficiency may be hard to justify.
Even some ancient coal boilers that were converted to gas decades ago are typically in the 80% efficiency range. Nearly all operating boilers are designed with sufficient heat transfer area to extract 80% or more of the gas energy burned in the burner.

Hard vs. Soft: Coal falls into two main categories: hard and soft. Soft coal is also known as brown coal or lignite.China produces more hard coal than any other country by a factor of about three. The whopping 3,162 million metric tons of hard coal produced by China dwarfs the output of the second and third-ranked producers—the U.S. at 932 million metric tons and India at 538 million metric
About 85% of all coal used for heating buildings in Europe is burned in Poland and, in many of the country's regions, coal is the main heating fuel for households. Data by the World Health Organization from 2018 shows that 36 of Europe's 50 most polluted cities are in Poland.
P. GoldsWorthy, E. On, in The Coal Handbook: Towards Cleaner Production: Coal Utilisation, 2013. Boiler efficiency and carbon burnout. Boiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler.
Burning coal produces numerous emissions that adversely affect the environment and human health. When coal is burned, carbon dioxide, sulfur dioxide, nitrogen oxides, and mercury compounds are released. For that reason, coal-fired boilers are required to have control devices to reduce the amount of emissions that are released.
