| With the improvement of living standards and social development, energy conservation become the theme of our lives. At the appeal of of low-carbon life, businesses are working hard on new products and technologies for energy saving and environmental protection .In the field of energy, the use of gas occupied all aspects of life, especially in the use of gas stove account for a large proportion.It is imperative for energy saving and environmental protection from the aspects of gas stove. Mainly in the aspects of development new structures and increasing the gas stove attachment. This article research the specific structure attachment of energy-saving cover and analysis of its energy saving features.This article uses computational fluid dynamics software FLUENT to simulation research energy-saving type and general type of two different structures gas stove in the case of use or no use energy_saving cover, obtain the temperature of combustion space. Through building mathematical models of gas stove at the cases of use and dosen't use the energy-saving cover and using the non-structure grid and the k-εdouble equation model as a turbulence model,we can establish the closed equations composed with the continuity equation,the momentum equation component,K equation andεequation.Using eddy dissipation components combustion model,definition boundary conditions in turbulent flow of chemical composition mix and reaction,separation solver used for initialization and solve combustion model,we can obtain the temperature.Through calculate two different structures of gas stove we know when using energy-saving cover the temerature is higher than no use. According to the calculated temperature with the basic knowledge of heat transfer we receive energy-saving gas stove in the situation of using energy-saving cover energy saving 28% , general-type gas stove energy saving 32%. Gas saving by experiments was 29% energy saving in energy-saving gas stove, common type gas stoves energy saving rate is 27%. Through experiments using energy-efficient energy-saving gas-fired stoves to save fuel after cover 29% of normal-type gas mask after using energy-efficient stoves to save fuel 27%. The average thermal efficiency of gas stoves has increased: for energy-saving gas stoves, energy-saving cover when not in use 33.5%; use the energy-saving gas stove is 47%. For normal -type gas stove, energy-saving cover when not in use 31% thermal efficiency, use the energy-saving gas stove thermal efficiency is 42%.Theoretical and experimental studies all demonstrated the effect of energy-saving cover.The study of environmental protection aspect of energy-saving cover chose CO and NO as objects.Energy-saving gas stove for the object, use thermal-type NOX model. Calculated by simulation after using energy-saving cover CO decreased, however, precisely because the combustion space temperature, the resulting increase in NO levels.Through research of gas stove energy-saving cover,we can say that using energy-saving cover gas amount used to reduce, this findings have certain practical significance to the fuel gas stove's energy conservation. |
