Avoid hypothermia and stay warm this winter – Ridge Times

 · This involves the transfer of heat from one object to another, with no physical contact required. For example, the sun transfers heat to the earth through radiation. "It is important to note that hypothermia is not just having a low body temperature or someone who is shivering.

Synthetic fuel

Synthetic fuel or synfuel is a liquid fuel, or sometimes gaseous fuel, obtained from syngas, a mixture of carbon monoxide and hydrogen, in which the syngas was derived from gasification of solid feedstocks such as coal or biomass or by reforming of natural gas.

 · , the operator of South Africa''s coal-to-liquid (CTL) plants, analyzed potential storage capacities in Mozambique, which would be about 600 km from ''s CTL plants []. This is no closer than storing CO 2 on South Africa''s coast, and would require a legal framework that is not yet in place, as discussions on CCS have not even started there [ 31 ].

Combine gas and coal feedstocks to displace high-cost oil

In contrast to the facilities in burg and Secunda, the feedstock for the Mossel Bay facility is natural gas from the nearby offshore E-M and F-A fields. Recently, reports in the press indicate that Petro SA is concerned about adequate supplies of natural gas to supply the operation because the offshore gas field supplying the facility is depleting.

The Design of an Axial Flow Fan for Application in Large Air-Cooled Heat …

The heat transfer characteristics of industrial air-cooled heat exchangers (ACHEs) are dependent on the ability of the fan system to deliver sufficient cooling air. However, under normal operating conditions, variable flow direction and strength often subject peripheral fans to distorted inlet conditions with an attendant reduction in overall volumetric flow rate and cooling capacity.

Synthesis Gas

Synthesis Gas The synthesis gas produced by autothermal processes using air as the oxidizing agent is low-lower heating value (LHV) while allothermal gasification produces medium-LHV syngas. From: Biohydrogen (Second Edition), 2019 Related terms: Al2O3

Carbon/Hydrogen Ratio

13.2.3 Heat transfer The carbon/hydrogen ratio of gas is considerably lower than oil or coal, which results in a flame of very low luminosity. Radiation from the flame is therefore low and furnace design must allow for heat transfer to be primarily by convection and conduction, together with re-radiation from hot surfaces.

The heat transfer is favored by high gas velocities and high ε ,L (ε s in Figure 33), which are typical for the heterogeneous regime. Fig. 33. Estimate of the heat transfer coefficients to vertical cooling tubes [Krishna and Sie, 2000]. 4.5.5 The model

Synthetic fuel

Heat is transferred by hot gases produced by combustion of part of the produced char. A modification of this process, the COGAS Process, involves the addition of gasification of char. [32] The TOSCOAL Process, an analogue to the TOSCO II oil shale retorting process and Lurgi-Ruhrgas process, which is also used for the shale oil extraction, uses hot recycled solids for the heat transfer.
