Abstract

The invention provides a coal-fired combustion improver with high stability. The coal-fired combustion improver is innovatively characterized by comprising the following components in percentage by weight: 20-30% of an oxidizing agent, 2-8% of a stabilizer, 20-30% of a catalyst, 2-3% of a dispersing agent, 10-20% of an emulsifier and 10-20% of a penetrating agent, wherein the stabilizer comprises 3,5-ditert-butyl-4-hydroxybenzoyl hydrazine, xylogen, silica powder, sodium sulfanilate and zinc stearate, or 3-methyl-5-tert-butyl-4-hydroxybenzoyl hydrazine, xylogen, silica powder, sodium sulfanilate and zinc stearate. According to the coal-fired combustion improver disclosed by the invention, the effect of adding the stabilizer into the coal is to mainly achieve the effects of delaying the decomposition rate after the oxidizing agent is heated and increasing the action time in the combustion system, and then the actual combustion effect is improved.

Description

technical field [0001] The invention relates to the technical field of combustion aids, in particular to a coal-burning combustion aid with high stability. Background technique [0002] Catalytic combustion aids for coal can be roughly divided into four categories: the first category is based on strong oxidants (such as nitrates, chlorates, perchlorates, permanganates, dichromates), or supplemented by industrial salts , MnO 2 , Fe 2 o 3 , sugar, urea, phosphorus and antimony sulfide, etc., or supplemented with CaO, MgO, Na 2 O sulfur-fixing agent; the second category is mainly various metal oxides and tailings; the third category is mainly low-molecular alcohols; the fourth category is mainly metal carboxylates, including acetate, oxalate Organic acid salts such as acid salts, succinates, and fatty acid salts. The first type of combustion-supporting agent with strong oxidant as the main raw material has a certain effect on reducing the ignition point of the material and...
