Abstract

The invention discloses a coal burning catalyst as well as a preparation and a use method thereof, which belong to the energy conservation and emission reduction field of catalytic combustion of the coal. The catalyst comprises the following raw materials in parts by weight: 326-472 parts of water, 202-292 parts of ferrous chloride, 125-181 parts of potassium chloride, 77-111 parts of calcium chloride, 48-69 parts of urotropin, 19-27 parts of tourmaline powder, 18-26 parts of fumed silica, 15-21 parts of octaphenyl polyoxyethyiene, 15-21 parts of sodium dodecyl benzene sulfonate, and 11-16 parts of methylene-naphthalene sulfonate. When the coal burning catalyst is used, the catalyst is diluted with water actively processed via the tourmaline powder, and then uniformly sprayed on the coal. The catalyst disclosed by the invention has the beneficial effects of low material price, no any safety hidden trouble, good stability and convenience for use. After the activating treatment carried out via the tourmaline powder, the effect of the catalyst is further improved, and the coal-saving effect and the sulfur fixation effect are obvious; and at the same time, the coking accidents of boilers can be prevented.

Description

technical field [0001] The invention belongs to the field of coal catalytic combustion energy saving and emission reduction, and in particular relates to a catalyst for improving coal combustion efficiency and reducing harmful emissions, and a preparation and use method thereof. Background technique [0002] In my country's primary energy consumption, coal consumption accounts for the largest proportion, close to 70% of total energy consumption, of which more than 85% of coal is used for direct combustion in thermal power generation, industrial boilers, industrial kilns and household stoves. At present, the utilization efficiency of coal combustion in my country is generally low, which not only causes serious energy waste, but also brings serious combustible air pollution. How to reduce energy waste and environmental pollution caused by inefficient coal combustion, the application and promotion of coal combustion catalysts is undoubtedly one of the effective means.
