Oxy-fuel combustion is one of the clean coal combustion technologies for CO2 capture. However, post-combustion capture is studied as a challenged technology against oxy-fuel combustion. This paper presented the life cycle assessment (LCA) of these two CO2 capture technologies used in the 300 MW...

This paper focuses on a Life Cycle Assessment (LCA) of four waste management strategies: landfill without biogas utilization; landfill with biogas combustion to generate electricity; sorting plant which splits the inorganic waste fraction (used to produce electricity via Refuse Derived Fuels,...

Municipal solid waste (MSW) is a potential energy resource which can be incineration to energy. Furthermore, it can conserve more valuable fossil fuel and improve the environment by lessening Greenhouse Gas (GHG) emission and the amount of waste that must be landfilled. This paper highlights the...

As the largest developing country in the world, China creates a considerable quantity of municipal solid waste (MSW), which is one of the most serious urban pollution sources. Not only can MSW to energy contribute to a significant reduction in greenhouse gas (GHG) emissions caused by landfills,...

Oxy-fuel combustion technology is an attractive option for capturing carbon dioxide (CO2) in power generation systems utilizing hydrocarbon fuels. However, conventional atmospheric oxy-fuel combustion systems require substantial parasitic energy in the compression step within the air separation...

An advanced oxy-fuel hybrid power system (AHPS) is proposed in this paper. Solar thermal energy is used in the AHPS to produce saturated steam as the working fluid, and natural gas is internally combusted with pure oxygen. It is in configuration close to the zero emission Graz cycle. The...

Growing concerns over greenhouse gas emissions have driven extensive research into new power generation cycles that enable carbon dioxide capture and sequestration. In this regard, oxy-fuel combustion is a promising new technology in which fuels are burned in an environment of oxygen and...

The characteristics of the flame behavior of a non-premixed oxy-methane jet were investigated by increasing the carbon oxide (CO) mole fraction in a fuel jet. In the current study, a lab-scale furnace was used with a slot-type burner to modify industrial furnaces. The flow velocity was fixed at...

In this work, pollutant emissions in a continuous bubbling fluidized bed combustor (∼3kWth) at oxy-firing conditions were measured. An anthracite coal was used as fuel and a limestone was added for sulfur retention. Flue gas recirculation was simulated by mixing different gases (CO2, SO2,...

The thermal reactivity and kinetics of four coal chars (HVN, UM, SAB and BA) in an oxy-fuel combustion atmosphere (30%O2–70%CO2) were studied using a thermobalance. The coal chars were obtained by devolatilization in an entrained flow reactor (EFR) at 1000°C for 2.5s under 100% N2 and CO2...
