摘要:

对将螺旋扭曲管用于燃机进气温度调节换热器进行可行性分析,模拟燃机进气加热器实际运行的工况条件进行综合传热性能实验研究,得到了传热与流阻准则关系式;引入综合评价因子概念并与传统钢铝翅片管换热器进行对比发现,螺旋扭曲管换热器是钢铝翅片管换热器的1.31~1.52倍。以某建设项目采用的E级PG9171E型机组为例,对采用螺旋扭曲管和钢铝翅片管的两种进气温度调节换热器进行对比发现:当采用螺旋扭曲管换热器时,在同样换热能力下,换热器风侧阻力增大了14.7%;在同等质量下,换热器换热能力提高9.9%左右。

Abstract:

The feasibility analysis of the use of spiral twisted tubes in gas turbine temperature control heat exchangers was carried out, and the simulation of the actual operating conditions of gas turbine intake heaters was carried out to conduct a comprehensive heat transfer performance experiment. The relationship between heat transfer and flow resistance criteria was obtained. By introducing the concept of comprehensive evaluation factor(η) and comparing the spiral twisted tube heat exchanger with the traditional steel aluminum finned tube heat exchanger, it is found that the value of η of the spiral twisted tube heat exchanger is 1.31—1.52 times of the steel aluminum finned tube heat exchanger. Taking the E-class PG9171E type unit used in a construction project as an example, comparing two kinds of intake air temperature regulating heat exchangers using a spiral twisted tube and a steel aluminum finned tube: when using a spiral twisted tube heat exchanger, under the same heat exchange capacity, the wind side resistance of the heat exchanger increased by 14.7%; under the same mass, the heat exchange capacity of the heat exchanger increased by about 9.9%.
