In the
combustion chamber of lead column,there are some problems that the second layer air has only a little of support burn
function,the support burn
function is lost in the third layer air,which are likely to lead to incomplete
combustion of coal gas in the combustion chamber.Combustion state in combustion chamber of lead column is measured.The measure results indicate that the combustion course of coal gas is complete combustion and the coefficient of wasting air of coal gas and the oxygen content in combustion outcome at the level direction are not uniform.According to diagnosis about combustion state of combustion chamber of lead column,some conclusions such as symmetrical distribution of gas,air and smoke in each spout of the same layer,flow of smoke in combustion chamber,and gas in the second layer,air in the second and third layer heated by straight rising flue that result in the biggish difference of the coefficient of wasting air of coal gas and the oxygen content in combustion outcome at the level direction,and that air in the second and third layer heated by straight rising flue and their biggish resistance along their roads are the causes why the second layer air has only a little of support burn function and the support burn function is lost in the third layer air,are obtained.The results of study will be beneficial to normal maintenance and operation of combustion chamber of lead column.
