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 boiler. This type of fuel is mainly composed of carbolic oil, naphthalene oil, creosote oil and anthracene oil. After analyzing coal tar, you were able to know it contains s 10% CO2, 1.2% CO and 8.7% O2 at 870°F. Saturated with water vapor and enters 70 degree F with 745 mmHg. a. The operators had no idea how much excess air was needed. What do you tell them? how much air is needed in how much air is needed in ft3/lb of coal? b. You need to make the report to be passed that day for the analysis of the burner gas. ultimate analysis of the coal. Initial data from the coal says it contains 73% carbon, 5.2% moisture and 10% ash. Assume negligible nitrogen and sulfur content. d. In order to effectively maintain the stack used for the combustion products, In one day, the boiler makes use of 50 tons of coal, how many ft3 of stack gas is produced?
