Abstract
Experimental studies of heated materials with the surface temperature from 313 to 363 К transported by conveyors in production conditions were carried out in order to obtain the data required for the design of heating and ventilation systems of conveyor galleries. Experimental researches were conducted analytically on a laboratory test bench, which allowed to simulate actual conditions corresponding to production ones as accurately as possible. The factors influencing the heat exchange of heated materials with the temperature from 313 to 363К under conveyor transportation have been identified. Calculated dependences have been obtained for determining heat release from the surface of these materials. The data provided in the present work can be considered more reliable than the data of the authors of previous studies, since the studies carried out by the latter were conducted with the use of less advanced equipment which lacks the capacity of accurate simulation of actual production conditions. The empirical dependences that enable the determination of local and average coefficients of general and convective heat transfer at conveyor transportation of materials with the temperature from 313 to 363К have been received, and the heat flux coming from heated materials’ surface calculation has been calculated. The obtained data are necessary when designing heating and ventilation systems for production rooms where conveyor transportation of heated materials with the temperature of surface from 313 to 363К is carried out.
