Embodiment 2

[0076] Such as figure 2 Shown, described tail gas dust removal bed equipment of the present invention, by dust removal bed bed surface 2-1, tail gas inlet 2-2, dust removal bed lower baffle plate 2-3, dust removal bed baffle plate 2-4 and tail gas outlet 2 -5, and the boarding ramps 2-6 form a closed space body; the exhaust gas enters the exhaust gas dust removal bed from the exhaust gas inlet, passes through the upper baffle and the lower baffle, and then comes out from the tail gas outlet and then enters the chimney for discharge; The waste heat of the exhaust gas is dissipated by the surface of the exhaust gas dedusting bed. In the figure, 2-7 is the traveling direction of exhaust gas.

[0077] The exhaust gas from the exhaust dust removal bed has been tested, and the total amount of harmful emissions has been reduced by more than 90%. The exhaust gas temperature is lower than 50°C.

Embodiment 3

[0079] An oxygen-enriched steam biomass fuel combustion-supporting agent, said oxygen-enriching steam biomass fuel combustion-supporting agent is composed of steam, biomass fuel and an oxygen promoter, and is directly compounded online by the synthesis equipment of Example 1 when coal is burned It is a fuel combustion-supporting agent that is ready to be mixed and sprayed, and enters the burning coal with the distribution air to support combustion; the weight ratio of the oxygen-enriched steam biomass fuel combustion-supporting agent is 1.2MPa water vapor: 50% content of methanol: 27% industrial hydrogen peroxide = 4: 3: 3; the weight ratio of the coal and the oxygen-enriched steam biomass fuel combustion enhancer is: coal: combustion enhancer = 9: 1.

Abstract

The invention discloses an oxygen-enrichment steam and biomass fuel combustion improver as well as synthesizing equipment and an energy-saving and environmental-protection method thereof. The oxygen-enrichment steam biomass fuel combustion improver comprises 4-6 parts by weight of steam, 3-2 parts by weight of biomass fuel and 3-2 parts by weight of oxygen assistant; and when coil is combusted, the oxygen-enrichment steam biomass fuel combustion improver is directly formed by compounding on line by using fuel combustion improver synthesizing equipment. The oxygen-enrichment steam biomass fuelcombustion improver can be mixed for spraying and enters the combusted coil along with air for combustion improvement. The fuel combustion improver synthesizing equipment is used for compounding the oxygen-enrichment steam and biomass fuel combustion improver in proportion on line by intelligent control and can realize the intelligent control on the stable-pressure combustion of fire coal runningequipment. The invention can effectively solves the problems of low combustion rate and low heat exchange rate of the fire coal running equipment to realize the purpose of saving fire coal by 25%-35%, and can effectively solve the problems of tail gas pollution and waste heat utilization of enterprise fire coal.

Description

technical field [0001] The invention relates to an oxygen-enriched steam biomass fuel combustion accelerant, its synthesis equipment and an energy-saving and environment-friendly method. Background technique [0002] The existing three mature and advanced coal-fired combustion technologies include coal-water slurry technology, oxygen-enriched combustion technology and coal-to-gas technology. Although their application in actual operation has very good energy-saving and environmental protection effects, there are still huge deficiencies, such as Although coal-water slurry combustion technology has been recognized by the country as an energy-saving and environmental protection technology, due to the large and complex operating equipment, the complexity of operation, and the huge investment and operating costs that are unacceptable to enterprises, enterprises It is daunting, and the promotion is hard to imagine; oxy-fuel combustion technology is currently recognized as a fuel-s...
