Oxygen-enriched air mixed blowing combustion adjuvant boiler energy-saving method and equipment used thereby

Abstract

The invention provides an energy-saving method of an oxygenized air mixed blowing supporter combustion boiler and equipment used by the method, belonging to an energy-saving and emission-reduction combustion technology of the boiler; the invention more particularly relates to an efficient energy-saving combustion technology combining oxygenized air technology and supporter combustion technology and equipment thereof; the effects of energy-saving and emission-reduction of the invention are different according to the different running situations and equipment of the boiler (kiln); the statistics obtained from the cases studies of dozens of boilers and kilns proves that the lowest coal-saving ratio is 5.7%, the highest coal-saving ratio is 25%, and the coal-saving ratio of a pulverized coal fired boiler of 670t / h in a thermal power plant is 8.34%, so that the statistical data shows that the effects of energy-saving and emission-reduction of the technical improvement measure are excellent, the technology can be widely popularized, and good social and economical benefits can be brought about.

Description

1. Technical field [0001] The invention relates to an energy-saving and environment-friendly combustion technology for burning coal, fuel oil and gas, in particular to an energy-saving method for an oxygen-enriched air mixed blowing combustion-supporting agent boiler that solves the current insufficient energy utilization rate, and the equipment used therein and its application. 2. Background technology [0002] my country's annual fuel consumption is about 2 billion tons of coal, 300 million tons of fuel oil, and more than 40 billion tons of natural gas 3 , and increasing year by year, but my country's energy utilization efficiency is far lower than that of developed countries. At present, existing oil and coal-fired large energy consumers, such as thermal power plants, industrial boilers, oil field boilers, gas generators, ceramic wall and floor tile combustion furnaces, steel ingot heating furnaces, cement kilns, etc., have insufficient combustion, low combustion efficien...

AI Technical Summary

Problems solved by technology

However, at present, these two methods of combustion are used separately, especially in the case of using the combustion enhancer alone, the cost and cost performance are not much improved, so it is common to use oxygen-enriched air alone to support combustion. At present, there is no combination of combustion enhancer and The scientific and organic combination of the two technologies of oxygen-enriched air is used together, which further improves the energy-saving and emission-reduction technology to a new level
