Energy-saving environmental protection coal combustion catalyst

Abstract

The invention discloses an energy saving and environmental friendly coal combustion catalyst, the catalyst is prepared through dissolving raw materials with the following mass parts in 100 parts water and evenly mixing, the raw materials and the mass parts are that: sulphuric acid plant residues 20-30, electroplating plant discard solution 25-35, electrolytic copper plant discard solution 25-30, nitrification rare earth 5-10, anionic surfactant 3-5 and soluble calcium salt 2-5. When the coal combustion catalyst of the invention is in use, the coal combustion catalyst is only needed to be evenly sprayed on the coal surface and sufficiently mixed evenly with a mixer. The coal combustion catalyst of the invention is applied to various coal powders spraying boilers, coal slurry boilers, chain boilers, boiling boilers, other forms coal-fired boilers and civil scattered burning coal which enables the use to be convenient use and cost to be cheap and can increase the combustion intensity and the fire box temperature of the coal, improve the combustion performance of the coal, lower exhaust emission volume, saves the coal by 10-20%, and the like.

Description

technical field [0001] The invention relates to the technical field of coal energy, in particular to an energy-saving and environment-friendly coal combustion catalyst suitable for various pulverized coal-injection boilers, coal-water slurry boilers, chain furnaces, fluidized fluidized boilers, other forms of coal-fired boilers, and civil scattered coal combustion. Background technique [0002] Coal is the most important source of energy in our country. Improving the combustion efficiency of coal and saving energy is the focus of our country's national policy and enterprise work. [0003] In the existing coal-fired process and equipment, there are generally low combustion efficiency and incomplete combustion, such as unburned coal in slag or fly ash (physical incomplete combustion) and combustible gas (chemical incomplete combustion) released with flue gas. incomplete combustion), etc. [0004] Existing methods for improving coal combustion efficiency and reducing unburned ...

Problems solved by technology

This method can play a certain role in some boilers or occasions with insufficient oxygen supply, but with the improvement of combustion equipment and technology, and the application of coal-water slurry, this method cannot show satisfactory results
