The application of FR-1 heat-reflective coating material in heater

FR-1 heat-reflective coating material is developed with regard to the defects of heat-radioactive coatings such as high heat loss, easy-falling off and short service life. The principle of the energy-saving coating material, acting as the medium, is to reduce the blackness of lining, decrease the absorption rate of radioactive heat, increase reflective rate, modify the lining with a fine reflective capability and reflect the radioactive heat from smoke and fire back into the heater during heat transfer. It was trial applied in SINOPEC's Guangzhou Company, Gaoqiao Company and PetroChina's Yumen Oilfield, and field applied in SINOPEC's Xiangfan Oil Transportation Company. Result showed that heat absorption at the backside of heater tube was increased up to 1.5%, the outer wall temperature of radioactive room was reduced at 10%~15%, heat loss was reduced to 30%~50%, the fuel saving rate reached 2%, the total heat efficiency of heater was raised over 1% and the annually average total heat efficiency of heater was improved over 1%.
