Corrosion-inhibiting combustion-supporting coke cleaning agent

Abstract

The invention relates to a corrosion-inhibiting combustion-supporting coke cleaning agent and particularly relates to short-chain dehydrogenase (SDR)-4# corrosion-inhibiting combustion-supporting coke cleaning agent which is applicable to different types of boilers and heating furnaces, which use residual oil, thickened oil and mashgas as fuel, and can support combustion and clean coke agglomerate. The SDR-4# corrosion-inhibiting combustion-supporting coke cleaning agent is prepared by weighing zinc oxide, alkaline earth element, zeolite catalyst, potassium nitrate, manganese dioxide, magnesium nitrate, and corrosion inhibitor in a ratio, mixing, placing in a grinding machine, grinding, drying and stirring and has the characteristics of multiple functions of inhibiting corrosion, supporting combustion, cleaning coke and saving energy.

Description

technical field [0001] The present invention relates to a corrosion-inhibiting, combustion-supporting and coke-removing agent, and more specifically, it relates to a combustion-supporting and ash-coking-cleaning substance suitable for boilers and heating furnaces that use residual oil, heavy oil and gas as fuel. SDR-4# Corrosion Inhibitor, Combustion and Coke Cleaner. Background technique [0002] At present, the use of thermal energy in my country is mostly coal, oil residue, heavy oil, gas, etc. Among them, the amount of oil residue, heavy oil, and gas used for energy combustion is still increasing. Coal is a non-renewable fuel. Excessive mining and unreasonable burning use will cause great waste of coal resources in our country. The application of oil and gas furnaces makes the oil residue, a by-product of the refinery, have new uses, which greatly reduces the pollution emissions of oil refining, and also reduces the cost of oil refining. However, when using oil residue, ...

[0002] At present, the use of thermal energy in my country is mostly coal, oil residue, heavy oil, gas, etc. Among them, the amount of oil residue, heavy oil, and gas used for energy combustion is still increasing. Coal is a non-renewable fuel. Excessive mining and unreasonable burning use will cause great waste of coal resources in our country

The application of oil and gas furnaces makes the oil residue, a by-product of the refinery, have new uses, which greatly reduces the pollution emissions of oil refining, and also reduces the cost of oil refining. However, when using oil residue, heavy oil, gas, etc. to burn , a large amount of acid putty coke will be formed on the heating surface, which reduces the heat conduction of the tube wall and causes corrosion to the tube wall, reducing the service life of the boiler. Great detriment to production safety

Therefore, there have been some combustion-supporting additives on the market. These additives have played a combustion-supporting role in the process of coal combustion to a certain extent. High and complex production process
