So SO2Concentration also will increase.And then fire coal fully burns, at this time CO2Concentration is stablized in a higher numerical value, and fire coal fills
Divided combustion causes after-flame good, and the flue dust of generation is gradually increased to a stationary value；And gradually release leads to SO to inorganic sulfur2Value by
Gradually rise to a stationary value.Coal-fired burning degree weakens after a period of stabilisation, and after-flame is gradually deteriorated, and leads to the cigarette generated
Dirt gradually decreases；The release decline of inorganic sulfur leads to SO2Value gradually drop to minimum.After smashing coal, unburned portion in fire coal
Separately begin vigorous combustion, thus leads to CO2Concentration, dust concentration and SO2It is synchronous to increase；But the because coal of unburned part
It is less, therefore CO quickly2Concentration, dust concentration and SO2Synchronous downward trend is presented.By analysis it can be found that although hand is burnt
The flue gas generating process of stove and its coal and to smash coal mode directly related, but dust concentration and SO2The variation tendency of concentration with
CO2The variation tendency of concentration shows surprising similitude.In brief, because of CO2Concentration reflects the burning feelings of stove chamber inner combustion
