The paper discusses possible ways of transporting liquefied natural gas (LNG), compares the estimated capital cost of the projects on marine and pipeline transportation of LNG and argues for the economic efficiency of LNG transfer pipelines. The authors offered the most likely options pipelines and LNG method of calculation of hydraulic parameters.
Water-coal slurries (WCS) are not much inferior to such fuels as oil, fuel oil and gas in their energy characteristics. Their combustion is characterized by high environmental safety, low ash content and high combustion efficiency. For efficient combustion of such fuels special requirements should be imposed on burner devices. Thus, the design of these devices should provide supply not only of fuel itself, but also special channels for supplying air as an oxidizer and atomizer and gas for ignition and maintaining combustion in the initial period. The calculation of basic values, describing the process of fuel combustion, the basic geometrical parameters for burner design and justification of design characteristics of a microdiffusion gas burner for WVS combustion are given.
