Abstract

The invention discloses a measurement design system and design method for a furnace wall insulation structure of a garbage incineration boiler, comprising: a furnace wall insulation system; a heating surface temperature control system; a thermocouple temperature measurement system; an infrared thermal imager temperature measurement system; a computer system; The data measured by the thermocouple temperature measuring unit is collected and recorded by the data acquisition instrument, and the temperature change curve and gradient of each layer of the insulation material of the furnace wall insulation system are obtained through the computer system, and the insulation characteristics of the insulation material are intuitively displayed; With the cooperation of the electric translation platform, the "point-line-surface" temperature data on the surface of the thermal insulation structure is collected to form a temperature cloud map; by adjusting the structural size or material of each layer of thermal insulation material in the furnace wall thermal insulation system, the surface temperature of the thermal insulation structure can be uniformed. . The invention has various functions, is simple and quick, and can conveniently change the thermal insulation structure form for the layout of the thermal insulation structure of the furnace wall of the garbage incineration boiler, and provides an optimized combination form of the thermal insulation structure.

Description

technical field [0001] The invention relates to the technical field of thermal insulation structure measurement and design and boiler thermal efficiency, and more particularly relates to the structural measurement, design optimization and the combination of different design structures of thermal insulation materials of different materials, thicknesses and surface emissivity on the surface temperature of a waste incineration boiler. Background technique [0002] As a waste treatment equipment, waste incineration boiler is of great significance to save energy and protect the environment. The optimization of the thermal insulation structure design of the furnace wall of the waste incineration boiler plays an important role in inhibiting the corrosion of the furnace wall, reducing the heat dissipation loss of the boiler and improving the thermal efficiency of the boiler. The heat dissipation loss of the boiler is an important part of the boiler performance assessment, and the re...
