- Gas metal arc welding is one of the arc fusion processes that is widely used in industry due to its high efficiency.
- In-situ combustion (ISC) for heavy oil recovery is a high-risk process and thus calls for a deep understanding of the coke combustion front.
- Spontaneous combustion of coal is one of the most severe hazards that affect the safety production.
- The release of potassium during biomass combustion leads to several problems as the emissions of particle matter or formation of deposits.
- The discharge of the flue gas is rich in water vapor and its latent heat, which leads to the main heat and moisture loss for the natural gas.
- Internal combustion engines consume about 90% of fuel refined from crude oil which supplies 30% of the annual global flow of energy.
- Fly ash is an industrial by-product from coal combustion and has been widely used as mineral admixture in normal and high strength concretes.
- Advanced coal and biomass-based gas turbine power generation technologies (IGCC, PFBC, PCFBC, and Hipps) are currently under development and demonstration.
- Gas diffusion-sorption is a critical step in coalbed methane (CBM) exploitation and carbon dioxide sequestration.
- A number of papers have been published in the open literature on the explosion welding of concentric cylinders and on the joining of tubes to tube plates.
- Oxy-fuel combustion technology has great potential as a technically feasible method to significantly reduce CO2 emissions from coal-fired power plants.
- In heat and power production, oil shale combustion forms substantial amounts of solid waste, including fly ash.
- There has been increased interest in the use of plasma actuators for flow control in aerodynamics and combustion to improve efficiency and reduce emissions.
- Efforts to improve the efficiency of internal combustion engines in applications such as heavy-duty vehicles where electric propulsion is currently unfeasible or need complementing are essential.
- Experimental research on combustion systems, from simple flames to internal combustion engines, requires the measurement of sufficient information not only to understand what is happening qualitatively but also to supply quantitative details of subprocesses for which predictive models hopefully can be developed.
- The conventional operation of a hydrogen internal combustion engine (ICE) under lean conditions results in low NOx emissions, however, at the cost of power generated.
- Aqueous suppression systems (i.e. fire sprinkler, water mist) have been extensively utilised for compartmental fire suppression due to their significant heat extraction ability.
- The high thermal load endured by scramjets can cause many damages to the combustion chamber walls of the engine which requires an efficient cooling of the latter.
- The importance of various form of heat treatment operations on medium carbon steel in order to forester the problem that may arise in making a wrong choice of these steel materials or faulty heat treatment operations which may give rise to serious disruption in terms of human safety, higher cost and untimely failure of the machine components is of great concern.
- Premixed charge compression ignition (PCCI) is a promising combustion strategy for reducing in-cylinder NOx and particulate matter formation in diesel engines without incurring fuel penalty.
- With the introduction of novel fuels, which may contain high levels of trace impurities including sulphur and alkali metals, industrial gas turbines are operating with increasingly corrosive combustion environments.
- Impingement of fuel sprays on solid surfaces is of interest in a wide range of industrial applications including automotive, gas turbines, and process and hazard analysis.
