According to heat transfer theory and the change of temperature field determined through experiment of coal self ignite at low temperature stage, thermal equilibrium method is developed to calculate oxidation heat liberation intensity of loose coal at different low temperature stage.
Based on the analysis of the dry deposition of air pollutants, the short term measurement methods of dry deposition is specially discussed in this paper, such as diffusion tube method, four sections of filter paper method and incline degree and thermal equilibrium method under the conditions of gas current, which is significant to the nnther study on the mechanism of the dry deposition of air pollutants and to the further study on the environmental influence by the dry deposition of air pollutants.
Reducing soil evaporation,the effect of saving water and reducing salt ions content of the top layer of soil were studied by thermal equilibrium method. The results showed that the soil evaporation was reduced by the Populus simonii ×(Populus pyramidalis + Salix matsudana)cv.
?Relationship expression of raising production and extending effective widthin roller kiln is given in this paper. Energy consumption equation and calculating rate of saving-energy by thermal equilibrium method is also introduced.
According to heat transfer theory and the change of temperature field determined through experiment of coal self ignite at low temperature stage, thermal equilibrium method is developed to calculate oxidation heat liberation intensity of loose coal at different low temperature stage. The speed of coal oxidation consuming O 2, creating CO and CO 2 is calculated by the concentration change of gas determined by experiment. Connected bond energy change in coal and oxygen combination proce...
The heat effect is multifarious during coal spontaneous combustion at low temperature, but the main is chemical reaction heat of coal and oxygen. Through simulating the process of coal self-ignite by the experimental unit loading coal 850kg, and according to heat-transfer theory and the change of temperature field determined through experiment of coal self-ignite at low temperature stage, thermal equilibrium method is developed to calculate heat liberation intensity of loose coal oxidation...
