Control system of heavy oil burner of carbon rotary kiln

Abstract

The invention relates to a control system of a heavy oil burner of a carbon rotary kiln, three oil nozzles are formed in a kiln head of a rotary kiln, each oil nozzle is arranged at the end of an oil injection gun, the oil nozzle is provided with an igniter; a shaping wind pipeline is formed in the kiln head, a combustion-supporting wind pipeline is arranged on the circumference of the outer side of the oil nozzle; each oil injection gun is connected with one oil supplying pipeline, three oil supplying pipelines are connected with the oil outlet pipe of the heavy oil burner, the oil inlet pipe of the heavy oil burner is connected with one end of the supercharging oil pipe, a heavy oil heater is formed between the oil outlet pipe of the heavy oil burner and the oil inlet pipe of the heavy oil burner, a supercharging pump is formed on the supercharging oil pipe, the other end of the supercharging oil pipe is connected with one end of a filtering oil pipe, a filter is formed on the filtering oil pipe, the other end of the filtering oil pipe is connected with a diesel tank and a heavy oil tank; the igniter is connected with the first compressed air pipeline. The control system of the heavy oil burner of the carbon rotary kiln has the advantages as follows: three oil injection guns are formed for increasing the regulating ratio of the oil amount and having good atomization effect, and thereby the supercharging pump can be matched with the oil nozzle better.

Description

technical field [0001] The invention relates to a control system, in particular to a control system for a heavy oil burner of a carbon rotary kiln. Background technique [0002] In the process of calcining green petroleum coke with heavy oil as fuel, the quality index of the calcined coke in the firing process has a significant impact on the balance and stability of the entire production process and the subsequent firing of carbon anodes. In actual production, raw petroleum coke composition and sintering temperature are the main factors affecting the quality of calcined coke. If the amount of fuel is not properly controlled, the temperature of the sintering zone is higher than the sintering temperature required by the green coke, and "overburned" clinker will be formed. If the calcination temperature is too high, the bulk density of the raw material will decrease, and the mechanical strength of the product will decrease. It is also not allowed to raise the calcination temp...

Problems solved by technology

Since the viscosity has little relationship with the pressure, the oil with higher viscosity is more difficult to atomize, resulting in poor combustion effect, difficult to ignite and unstable after ignition, low flame intensity, and easy to break due to insufficient combustion
