2. You are working for a power plant that makes use of coal tar, a type of liquid fuel as its raw material for burning in a boller. This type of fuel is mainly composed of carbolic oll, naphthalene oil, creosote oil and anthracene oll. After analyzing coal tar you were able to wow it contalns 85.9% 0,63% H, 2.2% S. 4.5% O and 1.1% N. You told the operators to make use of excess air for combustion. The air was assumed to enter at 30°C with 90%RH. In order to follow DENR regulations, you took a sample of the bumper gis to analyze its contents.   Midway your experimentation, the equipment you used broke so it only gave you a partial analysis of 10.64% CO, 3.19%, CO and 0.64% H. a. The operators had no idea how much excess alr was needed, What do you tell them? b. You need to make the report to be passed that day for the analysis of the burner gas. What analysis will you submit the volume of the bumer gas in m/ka tuel is aso needed in your report c. The alr to be supplied a controlled…
