between 0.80.9 kg/kWh, seven plants use between 0.9- 1.0 kg/kWh, and at three plants - coal usage exceeds 1.0 kg/kWh. Hence the efficiency of the plants and the coal usage per unit of electricity generation also differ at each plant. There is a need to modernize India's thermal power plants and reduce the coal usage per unit of

The application of CWS technology developed by Zhejiang University has been proven in more than 90 steam and power generating plants utilizing CWS in China, with capacity ranging from 1.5 MW to 200 MW.
Get A Quotecoal was performed in order to examine the environmental aspects of current and future pulverized coal boiler systems. Three systems were examined: 1) a plant that represents the average emissions and efficiency of currently operating coal-fired power plants in the U.S. (this tells us about the status quo),
Get A QuoteThe proposed methodology was successfully applied to the boiler of a 660 MW e coal-fired power plant. While the burner equivalence ratios predicted by the standard equipments were in the range 0.9-1.05, it was shown that the actual range was significantly broader (0.65-1.25).

Get A QuoteTwo advanced tools are combined for air-fuel ratios monitoring per burner in large boilers. • They were tested in a 660 MW e coal-fired power plant. • The measured ranges are significantly broader than estimated by standard techniques. • This helps optimising the combustion process for better performances and less pollution.
Get A QuoteThe boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal and about a 11% heat loss while firing natural gas. When firing natural gas, other losses such as dry gas loss, moisture in fuel and
