Hydrogen oxygen combustion-supporting device for improving combustion efficiencies of kiln in blown glass factory and boiler in power plant

Abstract

The invention relates to a hydrogen oxygen combustion-supporting device for improving the combustion efficiencies of a kiln in a blown glass factory and a boiler in a power plant. The device comprises a hydrogen oxygen machine, a hydrogen oxygen mixing tank, a heating tank and a mixed fan; a gas outlet pipe of the hydrogen oxygen machine and the gas outlet pipe of the mixed fan are connected with the tangent line of a cylindrical wall on the inner side of the hydrogen oxygen mixing tank; the gas outlet pipe of the hydrogen oxygen mixing tank is connected with the heating tank; and an exhaust pipe of an annealing furnace is connected with the heating tank. A mixed gas of hydrogen and oxygen heated by the heating tank is introduced into the boiler or the kiln to support combustion, so a fuel can burn fully. The device has the advantages of effectively improving the heating efficiency of the fuel, lowering running cost, reducing smoke emission and contributing to environment protection.

Description

technical field [0001] The invention relates to auxiliary equipment for glass factories and power plants, in particular to a hydrogen-oxygen combustion-supporting device for improving the combustion efficiency of furnaces in float glass factories and boilers in power plants. Background technique [0002] The glass industry and power plants are high-energy-consuming industries. The combustion part is the part that consumes the most energy in glass production lines and power plants. Fuel costs account for about 35% to 50% of glass costs. Power plants are even higher. As far as float glass melting furnaces are concerned, Most of the float glass melting furnaces designed by our country can consume 6500kJ / kg-7500kJ / kg of molten glass, while the large foreign float glass enterprises only have 5800kJ / kg of molten glass. There is a certain gap between us and the international advanced level. The thermal efficiency of glass melting furnaces in developed countries is generally 30% to ...

AI Technical Summary

Problems solved by technology

The thermal efficiency of glass melting furnaces in developed countries is generally 30% to 40%, and the average thermal efficiency of glass melting furnaces in my country is only 25% to 35%. Although power plant boilers have improved, their common problem is that fuel combustion is insufficient and the heating efficiency is relatively low. lower, thus higher cost
