基于特征结构的锅炉报价CAD环境

针对电锌锅炉结构复杂，其报价过程繁琐，周期长，且难于控制报价准确性等的问题，在分析电站锅炉报价设计应用的结构图形基础上，划分出锅炉图形的结构特征和参数特征，包括：炉膛结构，大屏过热器，高温过热器，低温过热器，高温再热器，低温再热器，省煤器及锅炉图形中常用的符号和标准图形等，并根据电站锅炉产品报价设计的需要，开发出基于特征结构和参数化的电站锅炉报价系统CAD环境，给出了该环境下的总体结构，开发特点及系统的功能实现等。

CAD Environment for Quoting Utility Boiler Based the Characteristic Construction

The authors discuss such questions for utility boiler as the complicated flameworks,combined quoting course, long cycle, hardly controlling the quoting veracity and so on. Based on the construction diagram of quoting design for utility boiler, Which is into the boiler sketch's construction and parameter characteristic. They are furnace construction, big screen superheater, high temperature superheater, low temperature superheater, high temperature reheater, low temperature reheater, economy coal implement, common use sign and standard sketch in boiler sketch, etc. According to demand of the quote design for utility boiler, the CAD environment of quoting system based on characteristic construction and parameter are developed. Total construction of this environment , developing characteristics and function of this system are given.
