Analysis Of Gas Emission Capacity Of Main Herbaceous Fuel Types Of Hei Longjiang Province

This article has taken the Daxing'anling and Liangshui Forest Farm of Xiaoxing'anling in Heilongjiang Province as research area,by the method of wild investigation and laboratory control condition burning experiments,measured and computed emission factors and emission quantity of CO₂,CO,C_xH_y,NO and SO₂ within 135 kinds of herbaceous in different burning stage,then from the perspective of release speed have analyzed the burning characteristics of different forest fuels,main content and results are as below:The difference of gas emission between different types of forest fuel was tested by the method of Lowest Significance Difference(LSD).The result showed that CO₂ was the dominating gas released during the fuel burning process,the difference of gas emission between different types of forest fuel was prominent(P＜0.05).The duration of sufficient combustion process was long,flaming stage proportion was larger,and the burning characteristics was obvious.Fuel of different herbal cluster analysis,the same family of herbs with similar emission characteristics.Different branches of the plant as a result of their physical and chemical properties of plant and C(N,S) elements,such as the differences may be the cause of its release in the combustion reaction of the various trace gases amount of different reasons.Determination of the 13 kinds of forest types under the herbal fuel combustion gas emissions,and significant testing.CO₂,CO,C_xH_y,NO and SO₂ emissions in five gas unit 50241.05,4272.894,127.4829,72.31481,366.7545 respectively.Different forest types of fuel combustion under the herbal release the five kinds of major gas emissions are among the significant correlation between.And grass,respectively,of 20 different parts of the fuel to release the five kinds of combustion gases,the main factor,CO₂,CO,C_xH_y some of the ground between the underground sections of significant differences.And NO,SO₂ emission factor between no significant correlations between.The results of the research will provide basal data and academic base for researching of gas emission from forest fuels burning.
