Sulfur dioxide removal efficiencies of 80-95% are possible, with lime slurry being somewhat more efficient than limestone slurry. Available cost estimates indicate that the addition of scrubbing facilities required for 90% sulfur removal at a coal-fired generating plant burning 3.5% sulfur coal would increase the total cost of power by 10% or more.

Pollution Control. Thermal Power Plants produce electricity by first creating heat, and the U.S.A. still produces most of our energy by burning fossil fuels (coal, natural gas, or oil) to create this heat. Despite our nation's move towards clean, renewable energy production, coal-fired plants still produce about 30% of our electricity.

involved in a HAZOP study of a coal grinding and firing system.

Clinker free lime (CaO f) should be as high as possible to avoid hard burning of clinker, but safely below value, inviting mortar expansion; normally, between 0.5% and 1.5%. Free lime indicates incomplete clinker burning, therefore should be monitored regularly and maintained closely in the acceptable range.

During the combustion process the sulfur in the coal combines with oxygen in the air to form SO 2. To remove the SO 2, the flue exhaust gases from a coal-fired power plant are commonly led through a spray of limestone slurry in a so-called scrubber. The resultant reaction typically captures 90% or more of the SO 2. Approximately 80-85%

A generalized material flow diagram for a lime manufacturing plant is given in Figure 11.17-1. Note that some operations shown may not be performed in all plants. The heart of a lime plant is the kiln. The prevalent type of kiln is the rotary kiln, accounting for about 90 percent of all lime production in the United States.

It takes as little as 1.4 kg (3 lbs) of pulverised coal in 28 m3 (1,000 ft3) of air to form an explosive mixture. Since a large boiler burns over 40 kg (88 lbs) or more of coal per second, the safe burning of pulverised coal necessitates strict adherence to planned operating procedures.

value of the coal under investigation is 5500 kcal/kg. One kg of clinker as clear from the Table-3 needs about 420 kcal/kg. This means that 5500 kcal is produced from the burning of 1000g coal; therefore 420 kcal of heat, which is needed for one kilogram of clinker, is obtained by burning 76.36g of coal.

Coal fineness has a direct relationship with its reactivity. Hence in the cement plant a special significance has been given to the milling behavior of coal. It has been observed that low volatile matter in coal can be co mpensated by finer grinding. It is also desirable that coal must have a high Hardgrove Grindability Index (HGI)
