Coal Gasifier & Biomass Gasifier
Syngas analyzer apply in gasifier 1. Coal gasifier The coal gasifier can be divided into four modes by the movement pattern of the coal in the gasifier: fixed bed (moving bed), fluidized bed, entrained bed and molten bed. While it can be summarized to atmospheric and high pressure styles according to the gasification operating pressure. Based on the feeding method, the coal gasifier contains ...

Thermodynamic performance simulation of a coal gasification and SOFC based combined cogeneration plant by energy and exergy analyses
This paper presents a thermodynamic model of a combined cogeneration plant that employs a coal gasifier, a gas cooler and a solid oxide fuel cell (SOFC) upstream of the gas turbine and a downstream HRSG to generate process steam at low pressure. Simulated performance of the plant with respect to variations in some design and operating parameters has been reported. While energy analysis indicates ...

Thermochemical reactor design and thermal breakdown in middle-rank coals
Experiments conducted at bench scale can throw new light on the operation of pilot and plant scale processes. In the coal gasification/combustion area, such experiments have ranged from determinations of coal reactivities for novel entrained-flow gasifiers, to investigating the fate of injectant coal during blast furnace operation. Meanwhile, the accurate mimicking of conditions within pilot and ...

Energetic and exergetic performance assessment of some coals in Turkey for gasification process
This paper undertakes a study on energetic and exergetic performance evaluation of various types of coals in Turkey, such as Armutcuk, Amasra, Zonguldak and Catalagzy hard coals and Tuncbilek, Beypazari, Cayirhan, Afsin, Soma, Yatagan, Can and Sorgun lignites for gasification purposes, where syn-gas may subsequently be used for the production of electricity, heat, hydrogen, etc. in industry. The ...

Can we bury the carbon dioxide problem?
Seriously — carbon capture and storage could be a game-changer. Mention “carbon capture and storage” — the process of trapping carbon dioxide produced in fossil-fuel burning or other industrial processes and burying it underground — in polite company, and you’re likely to be pounced on. It’s absurdly expensive. It can never be rolled out en masse. ...
