Insulation materials used in power plant

Thermal insulation refractory material in the electric power industry especially thermal power plants, such as coal-fired power plants occupies an important position. It has energy saving, reduce heat loss, to meet the requirements of the power plant production process, ensure theequipment, production and personal safety, improve the environment, improve the economic benefit, is an important part of the construction of power plants. So the power plant is commonly used in the refractory material is light heat insulation brick. According to the present and future development, electric power industry of insulating refractory material demand quantity big, more varieties, high quality requirements, which the fiber insulation refractoriness demand maximum, followed by hard material, and is lightweight materials and thermal insulation coating.

One, according to the various parts of the heat preservation refractory materials of the insulation requirements of choice

(1) The medium temperature of the equipment and the pipeline at 350~600 is chosen to use calcium silicate products, aluminum silicate composite insulation;

(2) with rock, mineral wool products such as insulation equipment and piping medium temperature less than 350 DEG c;

(3) The valve, elbow and other special-shaped pieces of light insulation material or heat preservation coating insulation;

(4) The use of ordinary aluminum silicate fiber rope insulation is less than 38mm;

(5) The low temperature equipment and piping in the wet environment are chosen for the insulation of the hydrophobic insulation material
