A coal containing 2% sulfur is burned completely to ash in a brick kiln at a rate of 30 kg/min. The sulfur content in the ash was found to be 6% of the initial amount of sulfur present in the coal fed to the brick kiln. The molecular weights of S, H and O are 32, 1 and 16 g/mole, respectively. The annual rate of sulfur dioxide (SO,) emission from the kiln (in tonnes/ year, up to two decimal places) is

Charcoal samples from Stonehenge in England wereburned in O2, and the resultant CO2 gas bubbled into asolution of Ca(OH)2 (limewater), resulting in the precipitationof CaCO3. The CaCO3 was removed by filtration anddried. A 788-mg sample of the CaCO3 had a radioactivityof 1.5x 10-2 Bq due to carbon-14. By comparison, livingorganisms undergo 15.3 disintegrations per minute pergram of carbon. Using the half-life of carbon-14, 5700 yr,calculate the age of the charcoal sample.

A 1000 MW pulverized coal fired steam plant (40% efficient) uses coal with a heat content of 11,250 BTU/lb. The coal has an ash content of 9%. Within that 9%, 65% is fly ash and the rest 35% is the bottom ash that can be regarded as a solid waste. The coal also has a sulfur content of 2%. What is the particular matter emission rate contributed by fly ash (ton fly ash/ hour)? Sulfur is removed in the form of CaSO3 particles using CaO, with 100% utilization of CaO. If the plant achieves 95% sulfur removal, what is the final sulfur emission rate (ton SO2/hour)? What is the solid contributed by formed CaSO3 (ton CaSO3 / hour)? What is the total solid waste produced by the plant (bottom ash + formed CaSO3, ton/hour)
You place a 20 g sample of solid waste in a drying oven overnight and find the mass in the morning (after the moisture has been evaporated) to be 16.2 g. A 1 g (wet) sample is also placed in a 1L water jacket bomb calorimeter and 0.18 g of ash remains in the sample cup after combustion. The temperature in the calorimeter is raised by 2.17 ˚C. Calculate the heat value on a wet weight basis, dry weight basis, and on a moisture and ash-free basis. Convert your values to BTU/lb
