Dragon And Phoenix Heat And Power Plant High-temperature Steam Pipe Insulation Technology Research,

The insulation of the thermodynamics installation and pipelines of thermal power electricity generation has significant sense, which contributes to increasing the installation's safe reliability, decreasing the heat loss, producing the warmhearted work environment, conserving energy and so on. The investment of the insulation material of the power plant takes about 1% of the total investment, what is more, taking consideration of the fire-proof material supplied correlatively, the total investment will be much more impressive. The developed countries such as Japan and America take great appreciation for the performance of insulation and energy conservation, and some greats middle-sized power plants have achieved considerable effect. Most of the high temperature steam pipelines of Longfeng heat and power plant have been worn* and the heat is lost seriously, which directly causes the energy cost of the corporation increases and the economic efficiency decreases, what is more, thanks to the high temperature in the workshop, the environment that employee staying is bad. Therefore it is necessary to perform the research of insulation technology for the high temperature steam pipelines of this corporation.This original presents the universal insulation materials and the general testing and evaluating method for pipelines' insulation of the thermodynamics power generating plant; Performs the insulation testing and evaluating of the high temperature steam pipelines of Longfeng heat and power plant; Takes composite structural research on the high temperature steam pipelines, and establishes the relevant optimizing physical and mathematical model of the insulation layer, confirms the constraint and boundary condition, carries on optimizing design for the thickness of insulating layer; In order to more systematically analyzing the present situation of insulation of the installation and pipelines of Longfeng heat and power plant, develops a suit of software namely "the information associated decisive system for the insulation project" , taking advantage of this software can achieve .the design, evaluation and direction to building for the insulation project, examine the criterion of design and building, the performance and manufacture data of different insulation material, which is convenient to the selection of insulation material.
