Abstract

The invention belongs to the technical field of coal combustion additives, and in particular relates to a coal economizing agent. The invention solves the problems of unobvious coal economizing effect, high addition level, pollution of the environment and non-compliance of Green blackness of the existing coal economizing agents. The coal economizing agent is prepared from the components in parts by weight: 22-26 parts of a combustion adjuvant, 28-41 parts of a mixed type strong oxidizer, 18-26 parts of a dispersing agent, 2-5 parts of a catalyst and 15-25 parts of a compound sulfur-fixing agent. The coal economizing agent disclosed by the invention can improve the combustion conditions of a furnace body and increase the air permeability of a coal layer, thus enabling sufficient combustion of coal, improving the coal-burning heat efficiency, reducing discharge amount of smoke, improving the thermal conduction efficiency, fixing sulfur to reduce smoke, reducing emission of CO, SO2 and the like, reducing environmental pollution, and achieving the purposes of combustion supporting, sulfur fixing, energy saving and desulfurization.

Description

technical field

[0001] The invention belongs to the technical field of coal combustion additives, in particular to a coal-saving agent. Background technique

[0002] Coal is one of the main energy and chemical raw materials in our country, especially as an energy source, it is the most widely used energy raw material in modern industry. However, as the reserves of coal resources on the earth are getting less and less, the price of coal is getting higher and higher, and the country and relevant departments have stricter and stricter requirements on coal combustion smoke exhaust. How to improve the utilization rate of coal and reduce its pollution has become an important world issue. According to the current research direction, the coal-saving agent can effectively solve these problems. However, the existing coal-saving agent is only in its infancy, the effect is not obvious, and there are problems such as large amount of addition, pollution of the environment, and substandar...
