This work is devoted to the study of energy technological parameters of heat pump utiliza-tion of exhaust gases heat from rotary kilns in production of building materials for heat technology and industrial heat supply. This goal is achieved due to the proposed new approach to the creation of energy-saving technology and improvement of the heat supply system based on the integration of contact-recuperative and thermal transformer heat recovery. The most important results are as fol-lowing: a modified dependence of the conversion coefficient, an effective system for removing the waste gas heat for industrial and urban heat supply, a thorough assessment of the energy efficiency of the developed system, the dependence of the actual conversion coefficient on the energy technologi-cal parameters, as well as a rational degree of the exhaust gases pre-cooling, depending on their ini-tial temperature and ratio of water consumption of the systems for technological and household pur-poses, and the range of their preferred ratio. The relationship between the consumption of the heating and heated medium in the process of the contact interaction has been substantiated. The results ob-tained differ from those existing by the complex accounting of the energy technological parameters in the analytical solution of the task. The practical significance of the results of the proposed tech-nical solution lies in the fact that they can significantly reduce the consumption of the burned fuel due to a substantial expansion of the energy potential of the recovered heat, reduce heat, dust and gas emissions. |
