Abstract

The invention provides a rare earth high-performance energy-saving boiler deashing and decoking agent and its manufacture process, which comprises selecting and weighing nitrates, cerium oxide, neodymium oxide, tinkalite, sodium carbonate, sodium chloride, calcium carbonate, magnesium oxide, agitating and mixing, congruent melting, drying, granulating and inspecting.

Description

Technical field: [0001] The invention relates to a rare-earth high-efficiency energy-saving boiler dust-removing and decoking agent and a production method thereof, which are used for dust-removing and decoking of industrial boilers and power plant boilers, and belong to the technical field of clean and environment-friendly products. Background technique: [0002] During the use of the boiler, due to factors such as its specific use environment and the user's use management level, the metal surface of the boiler often corrodes and scales, and the combustion, coal or oil always contains sulfur, moisture and other minerals Impurities. When the flue gas formed after its combustion forms a SO3-H2O-air system, it contacts with the metal when the flue gas flows through the tube wall, resulting in the formation of highly corrosive sulfate and sulfite (NaSO 4 , CaSO 4 , MgSO 4 、Al 2 (SO 4 )Wait. These minerals are in the form of ash, hard scale, and melting, which greatly redu...
