Problems solved by technology
Changes in gas temperature will also lead to changes in gas flow, which in turn will affect combustion and thermal efficiency
[0009] Since the control device of a conventional gas engine is very simple and can only operate in a fixed mode, it is impossible to realize the high automation, high safety, high stability and high intelligence chain control and intelligent alarm required by large and high-performance burners, obviously. There are defects such as low accuracy of air-fuel ratio, low heat conversion efficiency, poor stability and safety, and complicated operation process.

The invention discloses a numerical control gas burning device. The numerical control gas burning device comprises a gas valve assembly, a gas metering unit, a blower, an ignition device, a flame detection device and a high-intelligence control system, wherein the gas valve assembly, the gas metering unit, the blower, the ignition device and the flame detection device are arranged in sequence in a matching way; the high-intelligence control system is connected with the gas valve assembly, the gas metering unit, the blower, the ignition device and the flame detection device respectively. The high-intelligence control system is fully different from a special controller for the conventional gas engine, can be used for monitoring and recording an entire burning process and important parameters of a controlled object at any time, and can make sound, light and character information alarms in case of failures; a burner can be controlled automatically according to the severity of failures to take a corresponding measure for ensuring absolute safety of people and equipment.
Description
technical field [0001] The invention relates to a gas burner, in particular to a digitally controlled gas burner. Background technique [0002] At present, in the broad concept of burners, household water heaters, gas stoves, and even lighters can all be considered as a type of burner (or burner). According to its working principle, the burner can be defined as: it is a kind of equipment that converts substances into heat energy through the chemical reaction of burning, that is, air and fuel are mixed in an appropriate proportion through a premixing device to make them fully burnt. [0003] A gas burner (such as a natural gas burner) is a heating device that uses gas fuel. It is collectively referred to as a device that makes gas and air spray out and mix (or mix and spray) combustion in a certain way; gas machines are divided into industrial gas burners by type and application field Engines, civil gas engines, and special gas engines. [0004] Conventional proportional re...
