Gasification involves turning organic fuels (such as biomass resources) into gaseous compounds (producer gas or syngas) by supplying less oxygen than is needed for com­ plete combustion of the fuel. Gasifica­ tion occurs at temperatures between 1112o and 2732o F and produces a lowto medium-energy gas depending upon the process type and operating conditions. Gasification of biomass resources is ...

Coal gasification with carbon dioxide is a process for generating clean gaseous fuels and relieving greenhouse effect. Zhundong coal has high alkali and alkali earth metals (AAEMs) content, medium volatile and low ash in nature. Isothermal CO2 gasification of char derived from Zhundong coal (R-char) and char from acid washing R-char (AR-char) are performed in thermo-gravimetric analyzer (TGA). ...

C3F7H (FM-200) has recently been introduced as an alternative for Halon 1301 (CF3Br) fire suppression agent. In this paper, as part of an effort to study the effects of C3F7H on high temperature ignition of gaseous fuels, we are expanding on our earlier evaluations of ignition inhibition characteristics of C3F7H. Of particular interest is a better or improved understanding of the fundamental me...

We propose a conceptual study of prototype strained hydrocarbon molecules as high energy density additives for hybrid rocket fuels to boost the performance of these rockets without compromising safety and reliability. Use of these additives could extend the range of applications for which hybrid rockets become an attractive alternative to conventional solid or liquid fuel rockets. The objective...

Road transport is one of the most important factors for national economy due to its universality and comprehensive possibilities transporting people goods. Unfortunately, from energy point view, it also cost-intensive has a negative influence on natural environment. For these reasons, issues related limiting use conventional fuels are very important, which results in reducing emissions this sec...

The freight sector is expected to keep, or even increase, its fundamental role for the major modern economies, and therefore actions limit growing pressure on environment are urgent. use of electricity a option decarbonization transports; in heavy-duty segment, it can be implemented different ways: besides full electric-battery powertrains, used supply catenary roads, chemically stored liquid g...

This paper is devoted to the analysis of effect gas injection on efficiency gaseous fuel burning. A coaxial burner with a perforated inner wall presented in which methane–air acceleration observed. With use numerical analysis, it demonstrated that flame related flow separation from that, turn, leads reduction heat losses as well vortex formation and momentum losses. On basis obtained results, n...
