A mathematic model for the influence of extraction steam pressure loss on thermal economy of the unit was established based on the matrix thermal balance equation of the thermodynamic system.
基于热力系统结构矩阵,通过严密的数学推导,给出了定流量条件下抽汽压损对机组热经济性影响的计算模型。
A universal formula is raised to calculate flow of reheater when a unit of work substance is pushed out from extraction steam in reheating unit, and verified by examples.
导出了在再热机组中,排挤单位非调节抽汽流经再热器流量份额的通用计算式,并进行了验证。
Drying sewage sludge by indirect heating by extraction steam from turbine is the best technology for power generation by sludge incineration because the total cost of sludge disposal is the lowest.
采用汽轮机抽汽间接加热方法干化污泥,污泥处理的直接成本最低,是最佳的污泥焚烧发电技术。
