Natural gas is employed to reduce coke consumption in cupola furnaces with an open or closed top. The usual approach here is combustion of the natural gas by means of burners in external chambers at the perimeter of the furnace housing. Depending on their design, the burners ensure partial or...
摘要: Fig. 1. Change in the concentration of C02, CO, CH4, H 2 and carbon in a dry reformed natural gas as a function of the coefficient of air consumption. 1) At 1000-1100~(reformers UPI-SMZ); 2) at 600 3) at 20 (reformers designed by Giprosial and VNIIGAZ)....
Natural gas is used in boilers for space heating, hot water and steam generation, industrial furnaces, power plants for electricity production, and internal combustion engines. 天然气主要成分是甲烷,其他组分包含乙烷、丙烷、丁烷,及其他成分。常压下天然气表现为气态物质,可以压缩储存。主要通过管道气态输送,...
Heat pumps: This is really the way to go. As I said above, natural gas is really a fossil gas, it’s not natural at all (even if you buy “renewable natural gas” – see myfossil gasarticle for more on that). Heat pumps have a number of advantages over natural gas furnaces: high...

Natural gas reforming is indicated as an equilibrium-limited endothermic process, which is normally operated in a multi-tubular fixed bed reactor packed with nickel catalyst pellets, needing external furnaces to deliver the heat of reaction [100]. Nevertheless, this technology is accountable for the ...
Influencing factors and future trends of natural gas demand in the eastern, central and western areas of China based on the grey model Accession number: 20201208318017 Title of translation: Authors: Wang, Jianliang (1, 2); Li, Nu (1) Author affiliation: (1) School of Economics and ...
Climate change could significantly affect consumer demand for energy in buildings, as changing temperatures may alter heating and cooling loads. Warming climates could also lead to the increased adoption and use of cooling technologies in buildings. We a
Furnaces and boilers are examples of high-temperature applications of closed cavities. Consequently, some researchers have considered NCHT with radiation inside closed cavities23,24,25,26,27,28,29,30. In one of these studies, Karimipour et al.31 analyzed NCHT with radiation. They used a ...
The petitioners argue that the Clean Air Act requires the EPA to regulate pollution from residential and commercial furnaces. “The Clean Air Act says, in the text we cite a few times throughout the petition, that if the administrator finds that a source contributes significantly to pollution...
