Soft Sensors for Monitoring Combustion Quality and Flue Gas Emissions in Power Station Boilers

Flame Monitoring in Power Station Boilers Using Image Processing

Combustion quality in power station boilers plays an important role in minimizing the flue gas emissions. In the present work various intelligent schemes to infer the flue gas emissions by monitoring the flame colour at the furnace of the boiler are proposed here. Flame image monitoring involves capturing the flame video over a period of time with the measurement of various parameters like Carb...

Measurements and Modeling of Flue Height Influence on Air Pollution Emissions and Thermal Efficiency of Natural Draught Gas Fired Boilers

This paper presents and analyses results from experimental and CFD work undertaken on a 24 kW domestic natural-draught gas fired boiler. The effect of chimney height on boiler flue gases is being considered to address the need for increasing concern over environmental safety as well as saving of energy. A multi-component analysis computer (DELTA 2000 CD) is used to analyze the flue gases. 3D nu...

Air and Fuel Staged Co-combustion of Coal with Biomass in Power Station Boilers

The overall objective of this investigation is to develop a technology to employ biomass as substitute fuel for coal to help reduce NOx.. It was achieved by governing NOx formation kinetics through in-furnace air and fuel staged co-combustion technology. An extensive series of experimentation was carried out in a 20 kW down fired combustor to evaluate the effect of co-firing of Shea meal, Cotto...

Radon monitoring in gas turbine and thermal power station A comparative study

Background: In this study, measurement of indoor radon and its progeny levels was carried out in Gas Turbine Power Station in Haryana ( India ), where natural gas is used as fuel. For comparison, the results of a study carried out in thermal power plant in Haryana are also presented. Radon being a ubiquitous air pollutant has global impact and its monitoring in the environment at work places is...
