Calibration combustion device for flue gas analyzer, and method for self-adaptively controlling parameters

Abstract

The invention discloses a calibration combustion device for a flue gas analyzer, and a method for self-adaptively controlling parameters. The calibration combustion device for the flue gas analyzer comprises a gas appliance device such as a wall-hanging stove or a water heater, a flue gas discharge pipe, a main control plate, the flue gas analyzer and a communication adapting module, wherein the main control plate is installed on the wall-hanging stove; the flue gas discharge pipe is arranged at the upper end of the wall-hanging stove; a flue gas analyzer detection rod is installed at the inner side of the end part of the flue gas discharge pipe; the flue gas analyzer detection rod is connected with the flue gas analyzer through a conductive wire; and the flue gas analyzer forms connectioncommunication with the main control plate in the gas appliance device such as the wall-hanging stove or the water heater in a manner of conductive wire, Bluetooth, RF wireless communication and the like. According to the calibration combustion device for the flue gas analyzer, and the method for self-adaptively the controlling parameters, the data of the components of flue gas is collected by virtue of the flue gas analyzer, the exclusive combustion parameter data of each wall-hanging stove or water heater is established, a group of self-adaptive control parameters is automatically generatedby virtue of the internal software of the main control plate, and the optimal calibration compensation is carried out on gas component change, gas pressure change, altitude change and other variablesexisting in a use environment of a user, so that the elapsed-time maintenance for a good combustion working condition, of the wall-hanging stove or water heater is guaranteed.

Description

technical field [0001] The invention relates to the technical field of flue gas analyzers, in particular to a method for calibrating a combustion device and self-adaptive control parameters of a flue gas analyzer. Background technique [0002] At present, it is known that the gas flow control method of the wall-hung boiler with self-adaptive function is nothing more than the gas flow control method through the air / gas proportional valve or the gas / air proportional valve. The setting of the combustion parameters of the system formed by the air / gas proportional valve depends on the previous setting, and the corresponding exhaust gas parameters of the maximum power and the minimum power are read through the flue gas meter at the general inspection station or during installation, and the Manual setting adjustment of proportional valve. Using this adaptive control method of proportional valve and its adjustment method, the gas flow rate is controlled by the fan speed, and the ga...

Problems solved by technology

However, this self-adaptive control method has the following defects: although it can maintain the preset flow ratio of air / gas, it cannot take into account the changes in gas composition, gas pressure, or altitude changes in the user's environment. The resulting changes in power differences and the impact on the accuracy of adaptive control make the combustion system unable to maintain good combustion conditions over time when the gas environment conditions change. The burner and heat exchanger group produce serious harmful smoke emission products, which affect air quality and user comfort, and reduce product life

[0003] There is another gas / air proportional valve on the market, most of which do not have an adaptive control method, so for changes in gas composition, gas pressure, or altitude changes in the user's environment, compensation and feedback control cannot be performed, directly affecting The combustion conditions of the wall-hung boiler cause the combustion system to be in an abnormal combustion state such as tempering or floating fire for a long time, which will damage the burner, heat exchanger group, etc., and produce serious smoke emissions, which will affect environmental protection and reduce product life.
