Enhancement of the efficiency of burning low-reaction coal in the swirl burners of boilers at their high-concentration dust supply under pressure
Journal Title: Проблеми загальної енергетики - Year 2017, Vol 0, Issue 4
Abstract
We describe the results of investigating the work of swirl burners of TPP-210A boiler of a 300 MW power unit at traditional and high-concentration systems of dust supply and the influence of these technologies on the efficiency of burning low-reaction coal. The effect of using transport air in high-concentration dust supply on boiler operation is estimated. The results of our studies confirm the possibility of using designed burners of TPP-210A boiler in the case of its work with high-concentration dust supply under pressure. This technology enables one to enhance the efficiency of swirl burners, to reduce chemical and mechanical underburning, and to increase the gross boiler efficiency in the control range by 0.383 - 1.02%.
