In this work, a model of gasification process that enables all, material and energy balance, calculation of gas composition, gas heating value and reactor temperature is presented. The model parameters were estimated by laboratory experiments. A fraction of MSW generally separated from inorganic materials and biodegradable components, so called Refuse-derived fuel (RDF), was studied by material...

An interior trajectory simulation of the canister launched missiles has been developed with the help of FLUENT. One of the special features of this simulation is the method by which the coupled three-phase problem is reduced to solving the fluid equations only. Several new source terms describing the influence of droplets and particles on gas have been created in the present case and added to t...

PROCESS AND TECHNOLOGY STATUS – Combustion boilers are widely used to generate steam for industrial applications and power generation. While all kinds of energy sources fossil fuels, biomass, nuclear and solar energy, electricity can be used to generate heat and steam, the scope of this brief is limited to combustion boilers using fossil fuels and biomass. Boilers can be grouped into two broad ...

Currently, hydrogen is mainly produced through steam reforming of natural gas. However, this conventional process involves environmental and energy security concerns. This has led to the development of alternative technologies for (potentially) green hydrogen production. In this work, the environmental and energy performance of biohydrogen produced in Europe via steam reforming of glycerol and ...

A combined steam-gas plant with in-cycle steam gasification of coal and hot gas purification is considered as a promising technology for increasing the efficiency energy production simultaneous reduction in environmental impact. To intensify steam-air gasification, mechanical activation fuel used; it consists high-stress grinding mill-disintegrator. The supply to gasifier allows an increase rea...

this study mainly focuses on enhancing the overall efficiency of gas transmission networks. the authors developed a model with detailed characteristics of compressor and pressure reduction stations. following this, they suggested three different systems with gas turbine including: organic rankine cycle (orc), air bottoming cycle (abc), and abc along with steam injection (si-abc). in addition, u...

Nanotechnology has the potential to introduce revolutionary changes to several areas of oil and gas industry such as exploration, production, enhanced oil recovery, and refining. In this paper, the effect of different concentrations of Fe2O3 nanoparticles as a catalyst on the heavy oil viscosity at various temperatures is studied. Furthermore, the effect of a mixture of Fe2O3 nanoparticles and ...

Introduction The Water Gas Shift Reaction (WGSR), an important industrial reaction for the production of chemicals and/or hydrogen, is expected to play a key role in the integration of gasification technologies with a H2 production/recovery unit. The effluent stream of the gasifier, mainly H2, CO and CO2 at high pressure (up to 30 atm) and temperature (up to 1000C), will be directed to the wate...

Most parts of the electricity generating equipments in power plants work at elevated temperature and high steam pressure, including boiler, turbine and connected system of tubing and piping. The generating equipments operate with steam pressures in the range of 20MPa or even more and the steam temperature is also high in the range of 600 °C. This will be the condition of water and steam inside ...
