Although some flue loss is unavoidable, an equipment tune-up using combustion analysis data can often significantly reduce this source of heat loss and save fuel costs by improving fuel efficiency. (1 p, 1 K). We don't save this data. [ 4] divided the oxidation process of coal into seven stages: conception, complexity, self-heating, activation, thermal decomposition, fission, and combustion (in order). Data Table 2: Heating and Combustion Chemical Initial Observation Heating Observations Burning Observations Mg Looks like small pellets of metal, dull Very bright, not as reactive as with direct heat Burns much quicker Zn Looks like a dull metal.
