Problems solved by technology

[0004] However, the current start-up burner has a complex structure and many components
When igniting, the traditional ignition stick and the traditional permanent lamp are in the air flow, and the success rate of ignition is low. Therefore, some manufacturers still use manual ignition outside the furnace. The working conditions are harsh and the degree of automation is low.
In particular, for the four-nozzle coal-water slurry gasification process, the diameter of the gasifier furnace opening is small (Ф180mm-240mm), and it is usually impossible to install a pilot light due to the small space, but the air flow rate is faster, so the flame of the traditional main combustion gun More difficult to organize, higher risk of blowout
Moreover, traditional flame detectors often give false alarms, which is not conducive to flame detection in the furnace, and there are also potential safety hazards

Abstract

The invention provides an integrated gun for a start-up burner, the start-up burner, a using method and an industrial furnace. The start-up burner comprises the integrated gun, a flame detection system, a burner mounting seat and a field control box, and the integrated gun is mounted on the burner mounting seat and is a combustion device of the start-up burner; the flame detection system is installed on the burner mounting seat and used for detecting the flame condition at the position of an integrated gun spray head and sending detection data to the field control box; the burner mounting seat is in butt joint with a combustion chamber of the industrial furnace, so that the integrated gun spray head enters the combustion chamber of the industrial furnace; and the field control box is in signal connection with an ignition / flame detection control box and the flame detection system, local control over ignition and flame detection is achieved, meanwhile, control signals are transmitted to a central control DCS, and remote control is implemented. Through the structural design of the integrated gun, the structure of the start-up burner is simplified, the operation condition is improved, the automation degree is improved, the reliability of the start-up burner device is improved, and potential safety hazards in the using process are reduced.

Description

Technical field [0001] The present invention belongs to gasification, slag gasification, natural gas conversion, three waste (exhaust gas, waste liquid, waste solid) incineration and petrochemical and other energy chemical technology, which involves a integrated gun with burner, start burning, use Method and industrial furnace. Background technique [0002] The burner is used to heat the gasifier or other industrial furnace combustion chambers from ambient temperature to the operating temperature, and meet the requirements of the temperature rise rate, widely used in water coal (focus) pulp / multi-slurry gasification, drizzle gasization, Slag gasification, natural gas transformation, three waste (exhaust gas, waste, waste solid) incineration and petrochemical and other processes, and used as a gasifier, incinerator, heating furnace, hot air furnace main burner. [0003] Taking the water coal (focus) slurry process as an example, the current burner is currently used in the gasifi...
