lets answer this question first with a thought experiment. we will start by making an analogy to people. why do different people look different? small changes in their dna, as well as the types of inoyts or nutrients, how mych sun they get, ect. t....different types of furnaces for burning coal,keystoker a-120 coal hot air furnace from www.discountstoves.net depending upon its composition, each type of coal burns differently and releases different types of coal is also used in the industrial and manufacturing industries. there are numerous types of fossil fuel burning furnaces, although the most common burn gas or oil..department of energy philippines,types of coal according to increasing rank (in terms of hardness, purity and heating value) are peat, lignite, subbituminous, bituminous and anthracite. worldwide, coal is a sought-after energy source. it has the largest reserve and is often the cheapest of the fuel options. now that clean coal technologies are available, the demand for coal
different coal types have different properties, and have different emission rates of both carbon dioxide and air toxins over time, through coalification, lignite (brown coal), to sub-bituminous coal, to bituminous coal and finally to anthracite (black coal) charcoal and peat can sometimes be confused for coal, but they aren’t major types of coal.national geographic society,coal is a sedimentary rock, and bituminous coal frequently contains “bands,” or strips, of different consistency that mark the layers of plant material that were compressed. bituminous coal is divided into three major types: smithing coal, cannel coal, and coking coal.
