The insulation equipment required for thermal power plants mainly includes turbine cylinders, high-temperature valve flanges, main reheat steam pipelines, boiler headers, SCR denitration flues, hot air ducts, drain expansion vessels, etc. Rosewool Insulation Refractory Co.,Ltd. PLUS ceramic fiber blanket is preferred as the composite insulation inner layer for high-temperature vibration equipment and irregular overheating parts.

Is there any ammonia or sulfur oxide corrosion condition in the SCR denitrification area of the industrial plant? Is it necessary to use corrosion-resistant and hydrophobic insulation products? SCR denitrification is an efficient process widely used in industrial flue gas treatment at present. It relies on catalytic reduction reactions to decompose nitrogen oxides in flue gas and has become the choice of many enterprises for environmental protection transformation due to its stable treatment efficiency. There are ammonia and sulfur oxide composite corrosion conditions in the SCR denitrification area of industrial plants, and the corrosion risk varies significantly in different segments.

Power plant unit boilers, pipelines SCR、 What are the allowable temperatures of the medium in each part of the steam turbine and the design outer wall? The allowable temperature for important parts of the thermal system in power plants, such as boilers, pipelines, steam turbines, and outer walls, shall comply with the domestic thermal equipment insulation design specification GB/T 4272, which states that "when the environment is 25 ℃, the outer wall temperature of the equipment/pipeline after insulation shall be ≤ 50 ℃"; Some high-temperature equipment and areas that are not easily touched by people can be relaxed to ≤ 60 ℃. General requirements for thermal equipment in power plants: "The temperature of the insulation outer wall should be controlled within 50 ℃ to reduce heat loss, prevent burns, and reduce coal consumption of the unit.

Why does the temperature of the equipment casing in thermal power plants far exceed the design value, causing local overheating and infrared temperature measurement exceeding the standard? The equipment shell of thermal power plants is "hot to the touch" and the infrared temperature measurement exceeds the standard, usually not simply "the shell is hot", but a comprehensive manifestation of increased internal losses, increased contact resistance, deteriorated heat dissipation conditions, or external heat conduction. When making a judgment, focus on whether it is a uniform overall temperature rise or a local hotspot; Whether it changes with the load; Whether accompanied by vibration, abnormal noise, burnt smell, or discoloration.

High temperature resistant glass wool rolls for industrial equipment insulation materials? High temperature resistant glass wool roll felt used for industrial equipment insulation is an excellent inorganic fiber material. Based on ordinary glass wool, it significantly improves heat resistance through special formulas and processes, making it an ideal insulation choice for many high-temperature industrial scenarios. High temperature resistant glass wool roll is an efficient insulation product launched by Rosewool Insulation Refractory Co.,Ltd. for medium and high temperature working conditions (≤ 400-500 ℃).

This article explains the use of calcium silicate boards for insulation in steam turbine plants, covering plant enclosures, fire walls, and equipment partitions. It also shares selection tips such as hydrophobic and temperature-resistant boards from Rosetexwool.
