Description

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