Configuration Scheme

Low temperature economizer is an efficient way to recover the flue gas waste and to improve the efficiency of the boiler. Several basic layout of low temperature economizer are introduced in this paper. Layout is divided into flue gas side arrangement and water side arrangement. In this paper, combined with the parameters of a 600 mw, the economy of the different configuration is calculated and compared.

Pulverizing system equipped by fan mills uses three medium (ie. low-temperature furnace smoke, high-temperature furnace smoke, hot air) for drying coal, especially in large-scale plants burning lignite. A constantly increasing unit capacity leads to a more complicated design for pulverizing system, with a heavier weight of furnace smoke tube. This paper focuses on a research of water-cooled membrane flue tube instead of traditional inner and outer insulation tube through experiments like changing water side parameters to replace the low-temperature flue pipe from three medium to two medium (ie. adjustable-temperature furnace smoke, hot air). This paper studies heat transfer coefficient of water-cooled furnace smoke pipe at different flow rate and flue gas temperature though a established water-cooled furnace smoke pipe test bed. It is using a certain mathematic method to obtain dimensionless relationship among Nu, Re, Pr and obtain the dimensionless rule equation of water-cooled furnace smoke tube.

SO3 is one of the main precursors of atmospheric PM2.5, and its emission has attracted more and more attention in the industry. This paper briefly analyzes the harm of SO3 and the method of controlled condensation to test SO3. The effect of cooperative removal of SO3 by ultra-low emission technology in some coal-fired power plants has been tested by using the method of controlled condensation. The results show that the cooperative removal of SO3 by ultra-low emission technology in coal-fired power plants is effective. The removal rate of SO3 by low-low temperature electrostatic precipitators and electrostatic-fabric integrated precipitators can be exceeded 80%, while the removal rate of SO3 by wet flue gas desulfurization equipment displays lower than the above two facilities, and the wet electrostatic precipitator shows a better removal effect on SO3. With the use of ultra-low emission technology in coal-fired power plants, the SO3 emission concentration of the tail chimney reaches less than 1 mg / Nm3.
