⇔ Airflow and flue gas flow is slightly lower or about the same. Natural gas boilers operate at lower excess air (O2) and a different airflow requirement for stoichiometric combustion. Coal fired boilers normally operate with 3-3.5% O2 (about 20% excess air). Whereas natural gas boilers normally operate at 1-1.5% O2 (about 7% excess air).
A flue gas stack is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler, or other large combustion device.

SFD-GAS series has been developed for burning the low calorific gaseous process waste of industries such as blast furnace gas (BFG), coke oven gas (COG) in the power plant boiler of steelworks, etc. This SFD-GAS series has been playing an important role in energy saving in the steelwork processes and in their IPP power station.
This raises the possibility that power plant developers will continue to follow the pattern of the 1990s and rely heavily on natural gas plants to meet the need for new power generation.! With current technology, coal-fired power plants using carbon capture equipment are an expensive source of electricity in a carbon control case.

Almost all coal, nuclear, geothermal, solar thermal electric, and waste incineration plants, as well as many natural gas power plants are thermal. Natural gas is frequently combusted in gas turbines as well as boilers. The waste heat from a gas turbine can be used to raise steam, in a combined cycle plant that improves overall efficiency.

The thermal electricity supplied by ENGIE in numerous countries is based on a variety of technologies: Traditional thermal power plants: also called combustion power plants, they operate with energy produced by a steam boiler fueled by coal, natural gas, heating oil, as well as by biomass. The steam activates a turbine which, in turn, drives an
frequent interval. In Power plants it has number of boiling section. This boiling section produces the high temperature water of the steam. Boiler steam temperature in thermal power plant is very complex and hard to control, due to poorly understand the working principles; Boilers have many serious injuries and destruction of property.
2. Background Thermal power plants convert heat into power in the form of electricity. The heat is generated from a diverse range of sources, including coal, natural gas, uranium, solar energy, and geothermal energy. The heat rate (HR, kJ/kWh) of a power plant is the amount of heat input required (kJ/h) to produce one unit of
The Rankine cycle is a model used to predict the performance of steam turbine systems. It was also used to study the performance of reciprocating steam engines. The Rankine cycle is an idealized thermodynamic cycle of a heat engine that converts heat into mechanical work while undergoing phase change. It is an idealized cycle in which friction losses in each of the four components are neglected.
Thermal power plant or thermal power station is the place where we use the energy of heat to produce electric power, and it's the most convenient sources of electric power generation, as we burn fuels such as oil, coal or liquefied natural gas to produce high temperature, high-pressure steam then we use this steam to turn a steam turbine

power plants have been constructed in the last decade.1 Figure 1-1 illustrates the various components of a power plant and factors that affect its thermal efficiency. Operating experience reflects that the thermal efficiency of a power plant declines with use. Much of the efficiency degradation can be recovered during maintenance outages
Modern-day boilers, such as those in coal-fired power stations, are still fitted with economizers which are descendants of Green's original design.In this context they are often referred to as feedwater heaters and heat the condensate from turbines before it is pumped to the boilers.. Economizers are commonly used as part of a heat recovery steam generator (HRSG) in a combined cycle power plant.

Entropy tested the exhaust gases from the Unit 1 coal-fired boiler. The furnace burns bituminous coal. Gases from the combustion furnace pass through two electrostatic precipitators (ESPs) to control particulate. Gases exiting the ESPs pass through a flue gas desulfurization unit (FGD), to remove SO2, and are then exhausted through a stack.
