Water-based combustion-supporting coal gas frying-pan kiln and Mg catalysis low-CO2RO2 emission technology

Abstract

The invention provides a water-based combustion-supporting coal gas frying-pan kiln and Mg catalysis low-CO2RO2 emission technology. Air is not required to be blown in but water vapor completely replaces combustion-supporting coal, oil and gas, magnesium oxide mineral powder and the like are decomposed in a gasification hearth to obtain magnesium vapor, Mg, MgO, H, C, O and other vapor mixed flows detained in the eddy-current cavity at the top in the eddy current vacuum hearth achieve fully catalytic reaction to realize steady operation of a series of reaction dynamic equilibrium in the vacuum hot-carbon ultra-high temperature dry heat furnace environment of magnesium group vapor catalysis matched with mixed vaporization combustion, so that six-in-one ultra-high-efficiency energy conservation and environmental protection are achieved, the generated heat is exchanged in a three-pass hearth by a 'drum-header-tube bank' pressure-bearing assembly outside the dry heat furnace, and all superheat walls of the inner lining of the dry heat furnace are cooled in the way that an auxiliary engine drives recycling of flue gas.

Description

technical field [0001] The invention relates to a water-based combustion-supporting gas oil boiler furnace and Mg catalyzed low CO 2 RO 2 Emission technology, especially the use of water vapor to completely replace the combustion-supporting coal, oil, and gas without blowing in air. The magnesium vapor produced by burning magnesium oxide ore powder is used in the vortex chamber at the top of the vortex vacuum furnace. The steam mixed flow of vortex Mg, Mg O, H, C, O, etc. fully catalyzes the reaction, and the furnace is closed intermittently or continuously to push coal or jet oil injection and feed dolomite powder and other magnesium-containing raw materials in proportion, and the liquid is mixed in proportion The magnesium group steam catalyzed by gasification combustion is in the dry heat furnace environment of vacuum hot carbon and ultra-high temperature, and the heat is produced by the water-based heat exchange output of the "drum-header-tube bundle" pressure-bearing ass...

Problems solved by technology

[0002] At present, the known coal, oil, and gas combustion technologies all use traditional air combustion-supporting thermal equipment technology except for a small amount of metallurgical furnaces and other oxygen blowing or pure oxygen combustion-supporting technologies. Since most of the 78.9% inert gases in the air are nitrogen, not only It does not help combustion, but also "takes" a large amount of oxygen in the furnace (every 1 ton of N in the combustion product reacts to generate NO 2 , it needs to consume more than 2.29 tons of oxygen, resulting in an increase of 11,000 m to the excess air volume of the boiler and kiln 3 , based on the exhaust gas temperature of 200°C at 15°C, the additional incremental heat exhaust gas is 18,500 nm 3 , the sensible heat loss is as high as 256.32kJ / m 3 The total is 1.13 million kcal) and generates nitrogen oxides that are extremely harmful to human health (according to a research report by an authoritative organization in Western Europe in the 1990s that sounded the alarm to all mankind, if according to the Western European region at the end of the 20th century If the nitrogen oxide pollution situation is left unchecked, then the males in this environment will gradually lose their reproductive capacity), and at the same time, the sensible heat loss of flue gas emissions will also be greatly increased
