Technological method of water-coke slurry for glass melting kiln

Abstract

The invention discloses a coke water pulp application process for glass melting kiln, comprising the steps of: mechanically pressurizing coke water pulp containing petroleum coke of 45-75% and then feeding it into a coke water pulp spray gun, making its pressure be 0.3-1.5MPa in the spray gun, simultaneously switching on an air source to feed the air into the spray gun, regulating the air pressure to 0.3-1.5MPa in the spray gun, fully atomizing the coke water pulp and spraying the atomized coke water pulp into the flame space in the glass melting kiln, starting a fan to input combustion-supporting air and preheating the combustion- supporting air to 800-1520 deg.C by heat storage chamber, feeding the preheated combustion- supporting air through a small mouth into the flame space in the glass melting kiln, and thus making the atomized coke water pulp quickly ignited and fully combust. And it can make flame temperature up to 1650-1730DEG C in the glass melting kiln, assuring quality of glass products accords with technical requirements, and largely reduce glass manufacturing cost, save petroleum resources and benefit environmental protection.

Description

technical field [0001] The invention relates to a process method for using industrial kiln fuel, in particular to a process method for using water coke slurry fuel in a glass melting furnace. Background technique [0002] At present, in the glass manufacturing industry, heavy oil, coal tar or natural gas with high calorific value and low ash content are generally used as fuels to manufacture glass products. The shortage and high price have seriously affected the economic benefits of glass manufacturing enterprises. Water coke slurry is a stable slurry with a certain fineness, flowability and certain combustion calorific value, which is made of petroleum coke, a by-product with high calorific value and low ash content after petroleum refining, water and a small amount of additives through physical processing. fuel, its price is lower. Since the water coke slurry contains a large proportion of water, it needs to absorb part of the heat during combustion and gasification, so ...

AI Technical Summary

Problems solved by technology

Since the water coke slurry contains a large proportion of water, it needs to absorb part of the heat during combustion and gasification, so the combustion calorific value, combustion speed and combustion completeness of the water coke slurry are lower than those of heavy oil, coal tar or natural gas. At present, it is mainly used in power station boilers, ceramic hot blast stoves, steel rolling heating furnaces, etc. that do not require high fuel requirements. Since glass melting furnaces have higher requirements on combustion temperature and ash content, etc., at present, water coke slurry is used instead of heavy oil and coal tar. Or natural gas, etc., have not been reported on the use of glass melting furnaces as fuels.
