Flue Gas - an overview | ScienceDirect Topics

Syngas rich in CO, CO 2, and H 2 can also be generated by steam reforming of natural gas or from the gasification of biomass, municipal, agricultural, or industrial wastes [4548]. During syngas fermentation, autotrophs use CO and H 2 as electron donors to reduce CO 2.

Oxyfuel Combustion - an overview | ScienceDirect Topics

C. Shaddix, A. Molina, in Oxy-Fuel Combustion for Power Generation and Carbon Dioxide (CO2) Capture, 2011 6.1 Introduction. Oxy-fuel combustion of coal produces various changes in the combustion process itself. These combustion-related effects are manifest in coal ignition and coal char combustion and burnout and thus play important roles in the practical consideration of flame stability and

Superheaters - an overview | ScienceDirect Topics

Esa Kari Vakkilainen, in Steam Generation from Biomass, 2017. 7.2.1 Radiative Superheater. Radiative superheaters are used as the first heat transfer surfaces after the furnace. Often a platen arrangement is preferred to create a fouling-resistant construction. Spacing in the first superheaters can be from 150 to 1000 mm. Superheaters are the hottest heat transfer surfaces in the boiler, so

Combined cycle power plant - Wikipedia

A combined cycle power plant is an assembly of heat engines that work in tandem from the same source of heat, converting it into mechanical energy.On land, when used to make electricity the most common type is called a combined cycle gas turbine (CCGT) plant.The same principle is also used for marine propulsion, where it is called a combined gas and steam (COGAS) plant.
