With excellent flame retardation and thermal insulation properties, SY self-temperature regulation and phase change energy-saving wall insulation material (the material) is composed of concrete and volcano perlite. At present, applied research of this material is not very thorough,especially under the condition of temperature variation, seasonal wind change in North China. In this paper, finite element analysis of external wall insulation layer of the Experimental Teaching Building in Taiyuan University of Science and Technology under negative wind pressure effect is performed. The negative wind load calculated is applied to the surface of the thermal insulation layer as uniform load, and the results show that the material used in the building which shorter than 80 meters in the Taiyuan area has no shedding or destruction under the negative air pressure. This material is safe and available.

In order to obtained the constitutive equations of thermal insulation masonry, the four masonry with different angles has pressed. Study on thermal insulation of masonry compressive mechanical parameters of constitutive equation and two-stage by compression stress-strain curves obtained in the servo press machine tests and data processing. The Basic mechanics parameters can be provided for finite element analysis of thermal insulation composite wall. The experiments showed that the constitutive model is discretization and the maximum stress and strain by press machine testing is different from brick masonry. The constitutive model is close with curve by press machine testing. The performance of mechanics in thermal insulation wall can be application by the stress-strain curves of thermal insulation of masonry. The stress-strain curves based experiments can be used finite element analysis of thermal insulation wall.

The purpose of this work is to analyze the efficiency of the technical solution that is based on thermal insulation of the infrared radiant burner outer surface and to identify of the characteristics of combustion and heat and mass exchange processes. Calculation of the heat balance is performed for thermal capacities of 5, 10, 15, 20, 30, 40 kW and proceeding from the main goal that was to generate directed local heating of workplaces and production areas. We used Ansys Multiphysics software and Fluent CFD solver to implement finite element analysis. Calculation of the thermal insulation layer thickness for a given external surface temperature was additionally performed. The technical solutions offered provides an optimal thermal regime in the whole building and enable us to increase the efficiency of the high temperature infrared radiant emitter to 2-17% and a consequence of the system as a whole.
