Abstract

An increase in the heat transfer efficiency of the open-type heat recovery unit due to the sequential heat and mass transfer enhancement is considered. The graphs of variances in the water temperature, gas temperature, gas enthalpy and gas specific humidity at the end of each site are presented. The proposed designs of the open-type heat recovery unit can be used for the flue gas disposal, including the disposal of natural gas combustion products in the greenhouse facility.

Highlights

IntroductionThe studies conducted during the recent decades both in Russia and abroad have shown that the use of highly efficient condensation heat exchangers (CHEs), including the open-type CHEs (direct liquid and gas contact for deep cooling of the exhaust gases below the dew point), allows to make comprehensive solutions in relation to the energy preservation tasks and reduce the amount of harmful emissions into the atmosphere

Summary

Introduction

The studies conducted during the recent decades both in Russia and abroad have shown that the use of highly efficient condensation heat exchangers (CHEs), including the open-type CHEs (direct liquid and gas contact for deep cooling of the exhaust gases below the dew point), allows to make comprehensive solutions in relation to the energy preservation tasks and reduce the amount of harmful emissions into the atmosphere. Water heated in the CHE can be used in the construction industry to produce foamed concrete. The development objective is to increase the used design efficiency for the Donetsk Chemical and Metallurgical Plant and the Ministry of Industry, Energy and Science of the Sverdlovsk region due to the consistent heat and mass transfer enhancement. The proposed designs of the open-type heat recovery unit can be used for the flue gas disposal, use of the natural gas combustion products in the greenhouse facility
