Taking the Russion Boiler TПП 316/CO of Huaneng Nanjing Power Plant as an object of study, some results are compared with actual onsite operational parameters.
The basic situation of the retrofitted steam turbine control system (DEH) for a 320 MW unit at Huaneng Nanjing Power Plant has been presented, and combined with engineering practice, the new techniques used in retrofitting the said system and their features have been analysed and evaluated.
According to the development and composing of the power station SIS system this paper,carries on the detailed contrast and analysis between the real system and the SIS system,finally takes the Huaneng Nanking power station as an example,puts forward new thought to match the SIS system technology to reform gradually the existing real system.
On the above bases, the article analyse and establish the control strategy and method of AGC, and connect the AGC works of Huaneng Nanjing Power Plant, introduce the generally way of AGC system exploitation and operation in thermal power plant, and forecast the direction of the development.
In this paper,the physical and microstructural characterics tics of the glass microspheriods in coal powder fly ash from Huaneng Nanjing Power Plant,such as shape,size distribution,types of particles,kinds and content of mineral phases,weight percent of cenospheres, density and crustal thickness of microspheriods,as well as their thermal stability etc, have been researched by modern analytic technology in detail,and the genetic menchanism of cenospheres were discussded.
The paper presents the enthalpy equation at the entrance of starting separators in supercritical once through boilers, under the assumption, that, at low load, the water walls follow without retardation. Taking the mean enthalpy and the mean density as the characteristic variables, launching behavior of a starting separator in a supercritical once through boiler is simulated from a cold start up to throttling operation. Taking the Russion Boiler TПП 316/CO of Huaneng Nanjing Power Plant as an object of s...
The major chemical compositions and mineral phases are alike in the particles of powder fly ash with different sizes from Huaneng Nanjing Power Plant.The volatilization-condensation of the minerals of powdery coal in high temperature combustion results in that the trace elements tend to enriching in smaller particles of powder fly ash,and the degree of enrichment of trace elements is closely related to their geochemical properties and the average particle size of fly ash.The smaller particles are most serio...
