Simulates and analyses the heat energy collected by the solar collector, the inlet and outlet temperatures of heat transfer fluid in the energy storage tank, the mean temperature of the phase change material(PCM) and the heat losses from the energy storage tank under different combinations of the collector area and the storage volume for the system with PCM of CaCl2·6H2O applied to a vill.

In the light of the question of short life of regenerator in the process of applying regenerative combustion technology,the development and application of a new high efficiency,low resistance and long life regenerator is introduced.

for example,some problems were analyzed,such as(regenerator′s) agglutination,regenerative chamber leaking fire and air and reversing valve fault.

At first,the paper introduce the developing situation of the regenerator in china and then analysis,find that most part of researching to regenerator focus on design and the situation of online regenerator has been omitted,the paper provide a new method that realize the online diagnosing regenerator,the technology has been used in a large scale reheating furnace and result is good.

Basing on one-dimensional thermal circuit network model and auxiliary heat demand formula with temperature control method,the change of auxiliary heat demand and indoor air temperature under different auxiliary heat control constant and set-point temperature were determined,and the effect of set-point temperature on thermal storage of wall was also discussed.

The heat storage principle and material of electric heat solid heat storage device is introduced, and heat transfer analysis is made on the heating and discharging.
