Energy Efficiency Analysis of Direct Contact Solid State Thermal Storage Electric Boilers
Energy efficiency evaluation is an important manifestation of the effect of heat source energy use,the traditional solid thermal storage electric boiler due to the small specific heat capacity of air and the need for multi-stage heat transfer,which will reduce the heat transfer efficiency of the sys-tem,direct contact solid thermal storage electric boiler technology improves the heat transfer effi-ciency of the heat source,but the lack of a complete set of energy efficiency evaluation standards.The analysis is carried out using the energy analysis method to grasp the operating parameters of the heat source and the energy conversion relationship,determine the energy analysis model and calculate to obtain the energy efficiency evaluation index;then use the combination of weighting and other methods to determine the weight of the index,the fuzzy comprehensive evaluation to de-termine the score and level,to form the energy efficiency evaluation system of the direct-contact e-lectric boiler;and finally,combined with the theoretical analysis of thermodynamics and the use of specific experiments to validate the reasonableness of the evaluation system,to provide a compre-hensive set of evaluation criteria for the direct-contact solid heat storage electric boiler.Finally,the evaluation system is combined with thermodynamic theory analysis and specific experiments to verify the reasonableness of the evaluation system,which provides a reference for the technical im-provement and promotion of the development of direct-contact solid heat storage electric boiler.
