Mechanical Analysis of Ceramic Thermal Insulation Board in Boiler Insulation

In order to solve the boiler and coal load and load adaptability, according to the boiler required by the minimum stable load and coal characteristics, based on the two or three insulation products board laminated structure adjustable adjustable combustion zone.

Each group of adjustable fuselage device mainly consists of inner, middle and outer three layers of insulation board, each insulation layer by the microporous ceramic insulation board using embedded method and heat-resistant steel structure of the integrated structure of the insulation board The

Ceramic insulation refractory fiber board ceramic fiber paper directly exposed to the flame, the steel structure from the heat-resistant flat steel or angle welded together, from the flame directly. The heat-resistant side of the ceramic insulation board is processed into a smooth plane, and the back-fire side is a microporous structure layer, and its pore density can be controlled between 0.5 and 2.0 mm by the foaming manufacturing process.

Due to the use of embedded structure, under normal circumstances, ceramic insulation board from external force, and therefore its strength is not high. The friction of the entire insulating castables layer and the friction in the movement of friction by the steel structure of the insulating castable refractory layer, therefore, the entire adjustable combustion belt design requirements to ensure that: in the furnace conditions, each activity of the insulation layer of steel The actual operating temperature does not exceed its permissible long term operating temperature limit and requires sufficient strength margin.
