Abstract

The invention discloses a combustor, which comprises a combustion head, an ignitor, a fuel conveying / regulating device, a combustion air conveying / regulating device, a safe operation monitoring device and an electric control device, wherein the combustion air conveying / regulating device is provided with an air door mechanism controlled by an air door actuator and a frequency converter for controlling the rotate speed of an air blast motor and is provided with a displacement sensor which is linked with the air door actuator to control the output frequency of the frequency converter; a programming controller of the electric control device instructs the air door actuator to control the switching value of the air door mechanism according to the requirement of fuel loads; and the frequency converter adjusts the frequency output of the frequency converter to the air blast motor according to a switching value signal, which is detected by the displacement sensor, of the air door mechanism so as to control the rotate speed of the air blast motor. Thus, the firepower regulating ratio range of the combustor can be widened by the combination of frequency control and air door regulation.

Description

technical field [0001] The invention relates to a combustion device, in particular to a burner. Background technique [0002] Burners commonly used in heat exchange equipment such as boilers and air-conditioning units and heating equipment such as dryers and heat treatment devices are mechatronics products with a high degree of automation, mainly composed of combustion heads, igniters, fuel delivery / regulation device, combustion air delivery / adjustment device, safety operation monitoring device and electronic control device. Wherein, the function of the combustion-supporting air delivery / adjustment device is to blow enough air into the combustion chamber of the combustion head to meet the needs of fuel (such as gas or oil) combustion. The blower of the traditional burner operates at a constant speed, so that the motor of the blower still operates at a constant power during low-load combustion, resulting in a waste of part of the input power of the motor. [0003] There is ...
