### Energy Audit of Coal Fired Thermal Power Plant

Nitrogen content = 1.40 Oxygen content = 6.05 GCV of Coal = 3401 kCal/kg Step 1. Find theoretical air requirement Theoretical air required for complete combustion = [(11.6 X C) + {34.8 X ( X /8)} + (4.35 X S)] /100 kg/kg of coal = 4.74 kg/kg of coal Step 2. Find theoretical % at theoretical conditions = moles= +

Jun 15, 1994 · Entropy operated a mobile laboratory (FTIR truck) containing the instrumentation and sampling equipment. The truck was driven to the site at Kintigh station and parked near to each location. The test runs were performed over three days. Entropy tested the exhaust gases from the Unit 1 coal-fired boiler. The furnace burns bituminous coal.

### Combustion Efficiency and Excess Air

The consensus is that feedwater oxygen, iron, and copper content should be very low (e.g., less than 7 ppb oxygen, 20 ppb iron, and 15 ppb copper for a 900 psig boiler) and that pH should be maintained between 8.5 and 9.5 for system corrosion protection.

### Coal-fired power plants emission standards - ScienceDirect

Conventional PF coal-fired boilers, currently being used in the power industry, use air for combustion in which the nitrogen from the air (approximately 79% vol) dilutes combustion products such as CO 2 and water vapor in the flue gas. During oxyfuel combustion, a combination of oxygen (typically of greater than 95% purity) and recycled flue gas is used for combustion of the fuel.
