The invention relates to the technical field of decoking and slag removing agents, and in particular, relates to an environment-friendly and energy-saving decoking and slag removing agent for a boiler, wherein the decoking and slag removing agent is composed of the following substances in parts by weight: 60-80 parts of a magnesium compound, 9-16 parts of an oxidizing agent, 0.3-1.5 parts of a catalyst, 2-6 parts of a swelling agent, 3-5 parts of a corrosion inhibitor, 8-15 parts of a copper compound, 40-60 parts of a nitrate compound, 4-12 parts of zinc stearate and 7-9 parts of boron nitride. The prepared decoking and slag removing agent promotes generation of products at the initial stage of boiler combustion, improves boiler combustion, is different from potassium-sodium-based slag removing agents which are popular in the domestic market, and has the advantages that ash is converted from a glassy state to a crystalline state due to base type change, crystallization is promoted to be rapidly completed, the
