Abstract

The invention relates to the technical field of fuel heaters, in particular to an air quantity control system used for a power adjustable coil pipe type fuel heater. The system comprises a master controller, an oxygen sensor, a flame sensor, a motor controller, a damper controller, a speed adjusting motor, an air blower, a damper executor and a damper. The oxygen sensor is arranged on a smoke exhaust air flue, the flame sensor is mounted in a combustion chamber, the oxygen sensor is used for collecting the content of oxygen of waste gas, the flame sensor is used for collecting combustion states, a signal is fed back to the master controller, the master controller controls the motor controller and the damper controller, the motor controller drives the speed reducing motor to adjust the rotating speed of the air blower to change the air quantity and the air pressure of air entering in the air flue, the damper controller controls the damper executor to rotate a damper to the determined angle, the air flue air quantity is changed, the system is energy-saving and environment-friendly, system running is stable and reliable, and emission indexes can be improved.

Description

technical field [0001] The invention relates to the technical field of fuel heaters, in particular to an air volume control system for power-adjustable coil fuel heaters. Background technique [0002] Coil-type fuel heaters have been widely used in various cleaning equipment due to their advantages of high power density, durability and stable operation, and can also be used in field environments. In recent years, the power of this coil-type fuel heater has The demand for adjustable technology is gradually increasing, but the development of this power adjustable technology is restricted by the related supporting technologies that have not been properly resolved. Air volume control is one of them. At present, the air volume control methods of coil heaters mainly include the following two : [0003] 1. Match the blower and air duct; [0004] 2. Manual damper. [0005] When the use environment and working conditions of the heater are clear and fixed, the method of directly ma...
