flue gas emission temperature of gas boilers

An Overview of Combined Cycle Power Plant

Jun 26, 2020 · The gas turbine and steam turbine are coupled to a single generator. For startup, or 'open cycle' operation of the gas turbine alone, the steam turbine can be disconnected using a hydraulic clutch.In terms of overall investment a single-shaft system is typically about 5 per cent lower in cost, with its operating simplicity typically leading to higher reliability.

Flue Gas - an overview | ScienceDirect Topics

The flue gas of upward flow carries out heat exchange with the tubes, and the flue gas temperature field also gradually becomes uniform. In Fig. 30, the nonuniformity of the flue gas temperature along the x axial direction gradually reduces with increasing elevation. Uniform flue gas temperature distribution is achieved at y = 8.88 m

Incomplete Combustion - an overview | ScienceDirect Topics

Incomplete combustion is generally due to poor mixing of the air and fuel, insufficient residence time, insufficient temperature and low total excess air. Thus, significant improvement can be obtained in new but also in existing boilers by: • Improving primary, secondary and tertiary air distribution, this includes verification when a boiler is commissioned, or after major modifications; NOx

Combustion of Fuels - Carbon Dioxide Emission

To calculate the Carbon Dioxide - CO 2 - emission from a fuel, the carbon content of the fuel must be multiplied with the ratio of molecular weight of CO 2 (44) to the molecular weight of Carbon (12) -> 44 / 12 = 3.7. Carbon Dioxide emission from burning a fuel can be calculated as. q CO2 = c f / h f M CO2 /M m [1]. where. q CO2 = specific CO 2 emission [kg CO2 /kWh]

The output temperature of the flue gas is also high (450 to 650 °C). This is therefore high enough to provide heat for a second cycle which uses steam as the working fluid (a Rankine cycle ). In a combined cycle power plant, the heat of the gas turbine's exhaust is used to generate steam by passing it through a heat recovery steam generator
